kedei 3.5 inch spi tft lcd arduino in stock
Is there a chance of getting it working with an Arduino Uno R3 or Mega2560? The graphics libraries that use SPI that I"ve found keep mentioning the RST and DC lines, which aren"t present on this board.
I haven"t had the opportunity to try it on a Raspberry Pi yet. From pinouts of raspi (googled images) they only have one long strip of GPIO/etc connectors, do they not? Even if plugging this board onto the 40-pin connector, where the two 5V pins match up, on the raspi the opposing two aren"t GND, they"re listed as "+3,3V" and "SDA". Something tells me that.. well, either I"m missing something, or this display needs some form of connector between itself and the raspi it"s meant to run off originally. (Oddly enough, they came with raspi-with-TFT-on-top plastic enclosures, which wouldn"t leave any space for rewiring pins.)
I doubt it. It would be a lot cleaner with regular SPI for both. You just change mode each time. e.g. 9-bit mode #3 for TFT. 8-bit mode #0 for the XPT.
Ah-ha. The HC595 is a shift register. They might use them to produce 16-bit parallel to drive the TFT. If they do, it will be a nightmare. Even worse than 9-bit SPI.
Well, it"ll be interesting to see if I get this to work eventually. A quick guess would be that with L_CS pulled low, the LCD chip gets to talk with the MISO/MOSI lines. After initializing it, I suppose the next step will be to (read datasheet..) and see if the MISO/MOSI-lines are used to clock out display data with L_CS high so the LCD chip doesn"t listen to that garbage, or if it is meant to be fed through the LCD chip aswell.
16-bit modules are cheaper than SPI display modules. So it is quite possible that he has crippled the display with shift registers instead of buying a proper SPI module.
Oh, this makes it easier - googling for the tarball I needed (lcd_show_v6 for my board since it"s got "v6.1" printed on it) got me to OsoYooTFT/README.md at master · jgamblin/OsoYooTFT · GitHub and http://en.kedei.net/raspberry/raspberry.html
Hrmm.. I don"t think source is included. In the lcd_show_xx blobs are just kernels and modules, with a couple of very small scripts to copy the LED or HDMI kernel to the /boot place of the filesystem. (And no error checking, if you try copying the LED kernel, it backups the original kernel, but if you then run the copy-LED-kernel command again, it happily overwrites your original kernel, leaving you with two LED-enabled kernels and no original. hrrf..)
Well, I downloaded the whole 35MB .GZ file. Unpacked it and found 3402 .ko files. I presume that these are kernel object files. Nothing that looked remotely like source files for your TFT display.
Since the ILI9481 can be driven directly by SPI, this seems a crazy way to do things. Especially since a HC595 might be clockable at 100MHz but you need to wiggle all 24-bits. And an AVR can only manage 8MHz on a good day.
Not when you consider that once you have loaded an 18 bit colour all you need to do is toggle the T_CS pin at say 10MHz and you can load the same pixels sequentially at 10Mpixels/s (=180Mbps) i.e. clear the screen faster than it is refreshed. With SPI you have to keep serially sending the same pixel N bits of colour over and over again, which is very inefficient. In the worst case (where sequential pixels are different colours) the shift register still wins if you can clock it faster than an SPI link maximum rate (easy on higher performance computers) because the same number of bits need to be clocked whatever interface is used.
This suggests more control bit are shifted in than is actually needed, but my hunch of an 18 bit + control parallel interface to the TFT seems to be correct.
That aside, I sort of assume I"ll need a 3,3V logic converter, since the rpi has 3,3v GPIO pins and most arduinos have 5V? So I don"t accidentally burn out the display chips.
Yes, I expect that bodmer or myself could probably get you working if we made some inspired guessing with the schematic. You could always email Kedei and ask him for the genuine schematic. Make sure that you tell him the Revision number(s) on the pcb.
I had success with downloading Kedei"s 4GB images specific for the 6.1 board and putting on an SD card. Now the raspi boots up, and I see the boot messages scroll by. The original article said "expect about 6fps from the display" and that seems right - it"s jerky, but works.
I"m going to order a couple of logic level converters now (a pair of 74LVC245 should do nicely on a breadboard), and then I can poke at it from an arduino environment.

The display support comes before the assembly on the RJ45 connection. As a touch screen, I use the Elegoo Display 3.5 "inch TFT LCD touch screen monitor 480x320 for Raspberry Pi.
While googling for any info about lcd controller I came across this page: http://heikki.virekunnas.fi/2015/raspberry-pi-tft/, author managed to get from manufacturer patch file for kernel sources and tested it with 4.1.y - on which lcd worked. But still LCD replace HDMI, but I want to use this screen as additional for user interaction, while the bigger on HDMI as presentation monitor.
Since, fbtft has been merged with rpi kernel, so the fb drivers (including ili9341.c) was moved to fbtft_device driver (so the author of page can"t compile latest kernel with driver+patch).
So something about hardware, which I reverse engineered by the "hard way" - "grab multimeter and run through all LCD FPC pins and shift register pins"
Now I noticed there is "9486L" which can suggest that LCD screen is controlled by ILI9486L, I found this LCD on taobao too but I can"t contact seller.
I"m pretty sure about D/C (Pin 37 on LCD) and Reset (Pin 19 on LCD) pins by looking into driver code, but I can"t identify other signals (WR/RD/CS/etc...)
- Controller is not ILI9341/ILI9325 - those are for smaller displays (320x240, etc...), I guess this might be ILI9486/9488 because they are for 480x320 displays. But when I compared init with DS it does not fit right so LCD can have a clone of ILI9486/9488 ...
- Module use only SPI interface and two CE signals (CE0 for touch controller, CE1 for LCD shift registers - compared to others lcd modules, in KeDei module this is swapped),
This LCD Touchscreen HAT fits snuggly on top of the Raspberry Pi, practically form fitting on top of it so as not to compromise the overall dimensions of the credit card sized single board computer. The resistive touchscreen provides you with an easy way to display information coming off of the Raspberry Pi and the OS currently running on it.
The 4:3 aspect ratio backlit LCD equipped on this HAT possesses a resolution of 480 by 320 pixels with over 65 thousand colors and an SPI interface with a 16MHz driver speed. Simply plug the 13x2 GPIO header into your desired Raspberry Pi and you"ll be able to start using your new resistive touch screen!
This is a modified version of the official PJRC ILI9341_t3 library (https://github.com/PaulStoffregen/ILI9341_t3) to work with KeDei Raspberry Pi displays.
And it is always a Work In Progress. Also using a lot of work from the the Raspberry Pi implementation: https://github.com/cnkz111/RaspberryPi_KeDei_35_lcd_v62
This library was created to allow extended use on the KeDei Raspberry Pi display and supports T3.5, t3.6 T4 and beyond. It also has support for other T3.x boards as well as TLC.
Your SPI communications on this board does not go directly to display but instead go to three shift registers. There are also two SPI Chip select pins, one labeled, which looks like it is for the Display and the other looks like it is for the touch controller. This is partially true.
However the SPI communications with the display are a lot different than any other I have seen. For example there are no reset pins, nor a Data/Command(DC) pin. Instead this information is encoded into the SPI data that you send to the display.
We figured it out, as the RPI startup code, did several strange SPI transfers at the beginning, which appeared like they were directed to the XPT2046 Touch controller.
This library borrows some concepts and functionality from another ILI9341 library, https://github.com/KurtE/ILI9341_t3n. It also incorporates functionality from the TFT_ILI9341_ESP, https://github.com/Bodmer/TFT_ILI9341_ESP, for additional functions:
The teensy 3.6 and now 3.5 have a lot more memory than previous Teensy processors, so on these boards, I borrowed some ideas from the ILI9341_t3DMA library and added code to be able to use a logical Frame Buffer. To enable this I added a couple of API"s
Place the Adafruit_ILI9341 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE
I successfully installed KeDei 3.5 inch 480x320 TFT LCD on a Raspberry Pi Zero with Raspbian Buster. It works nicely as text console, especially when I use lens to magnify the view. :-)
However, I want to use it for another purpose: I would like to keep the regular screen & console output at HDMI port and use the LCD as a special-purpose peripheral.
Is there any tutorial how to set up this kind of device (TFT LCD with SPI interface) either as a serial port, or some other kind of device that would allow it to be used by a single application for special prupose, such as control panel for some communication equipment?
3) pls try to install the image with raspbian and 3.5 driver and try it again: https://osoyoo.com/2016/05/26/osoyoo-lcd-touch-screen-for-raspberry-pi-installation-guide/
Hey Nikeron, is the used module really an ILI9325? Maybe we could then traceback the display connection and reverse-engineer it. From that point on when the schematics are released for everyone to build those displays themselfes, we could hack it then and create a free driver?
I downloaded RetroPie from https://retropie.org.uk/docs/First-Installation/ and have been trying to get my 3.5″ LCD to work. I downloaded the driver from http://kedei.net/raspberry/raspberry.html as described, but whenever I try and extract it with the “tar xzvf LCD_show_v6_1_3.tar.gz” around 50 lines are executed and then the Pi crashes. When I restart it, it goes into a kernel panic every time. I’ve reinstalled my OS multiple times. I cannot download the raspbian distro with the driver because I have been unable to install RetroPie on top of it and have been unable to display it on the LCD.
Do you mean you don’t want to install the LCD driver but just install OS? If so, this LCD can’t work, but you can search a 3.5 HDMI LCD in our store and it works with just OS for display function.
Hi, I got version 6.3 of the screen. I tried installing it on the latest Raspbian with latest drivers from kedei.net. But when the Raspberry starts booting, the screen only works for a few seconds before being frozen. ( Raspberry works, only screen is frozen ).
I had this happen initially. To resolve it I DISABLED SPI under raspi-config and then also set the bootup settings to be Desktop. I have a weird keyboard and the CTRL-ALT Fn keys didn’t work right, but normally CTRL-ALT-F1 or F7 change you from terminal to desktop virtual sessions in Linux.

Hello, I have been able to install the driver and play/switch between LCD & HDMI, now is there any way to turn off the white screed or turn off LCD when Im not using it? Thanks
The LCD doesn’t do anything else. Initially I had the Memory split set to 16MB – but this through up a memory error on the LCD. Setting it higher removes this error – but still nothing else.
I orderer a 3.5″ SPI touchscreen with a Raspberry Pi 2 and a case, thinking it would be easy to set up, as it seemed to be like the one here. Unfortunately that was not the case.
With some googling I found out it was made by KeDei LCD and exactly this screen. Identifying strings on the screens were “Madei in KeDei of china”, “3.5 linch SPI TFTLCD”, “480*320 16bit/18bit” and “vision 1.0 2015/6/11”. I hope the guys who made this screen can write code better than english… Seems like it requires custom drivers by KeDei. Drivers could be downloaded from Baidu and they include the diff to compile your custom kernel. I haven’t compiled kernels before, so lets see if I could manage without doing that.
I installed Ubuntu on my Macbook Pro on an external hard drive (which is a whole another story, thanks to EFI), so I could follow instructions on Raspberry Pi pages. Compiling on RPi is quite slow (tried that overnight), so cross compiling is the way to go. Following the instructions worked pretty well, however I cloned tools to my home directory and added /home/heikki/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin to my path. After that everything worked as expected. After cloning and changing branch to rpi-4.1.y I patched semi-manually from the supplied diff from KeDei, however I have uploaded my updated diff to make it easier for you. There’s instructions on patching too, but long story short it’s “cat
You should now have two framebuffer devices, /dev/fb0 and /dev/fb1. I’m not quite sure how the fbtft library interferes with the patch, as it seems to be activated too, but it works so no problem. (Actually I first activated module fb_ili9341, so you can try that too, if it contributed to my success). You can change to console to fb1 by command “con2fbmap 1 1” and back with “con2fbmap 1 0“, or on boot by editing /boot/cmdline.txt: add “fbcon=map:1” to the line somewhere. You can also change the font with “fbcon=font:ProFont6x11“. More things like this here.
However changing the size of the table from const unsigned char font16_B[96][16] to const unsigned char font16_B[96][8] means that the characters displayed on the TFT screen will be smaller.
Using Preprocessor directives to select the font table to use and selecting a subsection of the file font8x8_basic.h from Hepper"s GitHub repository, I added the following to the KeDei TFT library.
I have forked the KeDei TFT library source code from Osoyoo"s GitHub and have begun modifications to the source. The fork is located at https://github.com/RichardChambers/driver/tree/master/KeDeiTFT
In order to support the number of buttons, I rewrote the Button class so that I could have buttons which share some data thus saving about 11 bytes per button. So this GUI with eight buttons that are using the data sharing feature saves some 77 bytes of memory, a significant saving for an Arduino.
Thanks for bringing this to my attention. It appears that the upgrade package overwrites the FBTFT drivers, in particular, the Raspberry Pi bootloader. This seems to solve the problem:
I just tested this, and it looks like the difference is how SPI is enabled. In the RPi 2 it’s enabled in raspi-config, not commented out in the blacklist file. I just updated the post so it should work now!
Looks like the only difference is in how SPI is enabled. In the new release of Raspbian, SPI is enabled in the raspi-config menu under advanced settings. In older versions of Raspbian, it is enabled by commenting out the line in the blacklist file

Hello..I tired to interface this lcd “https://www.crazypi.com/raspberry-pi-products/Raspberry-Pi-Accessories/32-TOUCH-DISPLAY-RASPBERRY-PI” to my Raspberry pi model B+.I got a DVD containing image for LCD in the package.I burned it to the SD card and plugged in the display.But my lcd is completly blank.But green inidcation led (ACT LED) in board is blinking.Why my LCD is Blank ?
My Touchscreen is now working fine.The problem was for the ribbon cable on the back side of LCD.It was not connected properly.I just tighted the cable and it worked fine.Hope it will be useful tip.
Thank you for this great tutorial. I looked everywhere for this information. I have an eleduino 3.5 version A. I was able to get it working on my Pi 2 by following your tutorial and using flexfb as the screen type. I got the other settings from the image that came with the product. I did find that the ts_calibrate didn’t recognize the screen so I installed xinput-calibrator and it worked fine.
What other settings are you speaking of? Where are they on the image? I’m also using the Eleduino 3.5, but I’m not sure which letter version it is. It says version 141226 on the back, and it’s a black PCB.
Just got my Pi2 running Wheezy, working with the Eleduino 3.5 LCD without running the OEMs image… kinda. I didn’t want to rebuild the application environment again, so was avoiding flashing the SD.

Did you check to see if your device is supported yet? The device name should be specific for your screen, as listed in the fbtft file linked to in the beginning of the post
I too have a raspberry pi 2, and a waveshare spotpear 3.2 RPi lcd (v3) and I just can’t get it to work! I suspect I have a faulty LCD, but thought I’ll try this forum for help before I sent it back.
Soon as the pi is powered, the LCD lights up all white, with a few vertical pixels coloured at one of the edges, and nothing else. I don’t think that should happen – not at least before the BOIS has started up.
Anyway, point 1, says to change to dev/fb1 – I don’t have fb1. Only fb0 appears to be there. is that a clue what could be wrong? I have enabled SPI (is there a command to tell if its enabled?) I have also ran spidev to troubleshot (though I haven’t a clue what I means)
Any ideas what going wrong? I am using the latest “2015-02-16-raspbian-wheezy_zip”. Enabled SPI. done all the steps. Even changed mmcblk0p2 to mmcblk0p6 as suggested by Dabomber60 (but that freezes for me)

It seems all appears to be working – just the LCD is still all white with a single line of coloured pixels on edge) and nothing else. Is there a way to output, like jeff G script, of touch points?
I had the same one, I finally found a driver for it here: http://www.waveshare.net/wiki/3.2inch_RPi_LCD_(B) you will need to translate the page, but unpack the driver then run sudo ./LCD-show/LCD32-show. It should reboot and all will be good with the screen :)

The LCD display shows the raspberry correctly. However, the touch screen input does not work. The mouse pointer can I move correctly with your finger, but I can not select things (function of the left mouse button).
Can someone upload SD card image that works with RBP2 ? My idea is to use Eleduino TFT as additional screen and play movies via HDMI.. is it possible?
Do not follow this article when you don’t know what kind of LCD module. In my case, I follow all of this and my raspberry pi cannot boot anymore. I will try to recover, but I think I should format my SD card and reinstall OS.
Expecting this would builtin driver module within kernel and help with avoiding mistakenly overwriting anything. But with this is cause LCD screen to go blank white and no boot activity. Also noticed on HDMI it get stuck on Initial rainbow screen and stuck on that.
Does anyone tried splash boot screen with waveshare v4 LCD and Rpi2? I tried to follow some example from https://github.com/notro/fbtft/wiki/Bootsplash but no success.
Great tutorial thanks; got an X session working great 1st time. Has anybody managed to get Kodi/XMBC working on the LCD either Kodi standalone, Raspbmc or Xbian?

After following this tut to the letter on a brand new image of Raspian, I find that the touch driver does not function. Anyone experience the same? Basically all I did was image a current copy of rasping, did a apt-get upgrade, and then did this tutorial. Then the touch driver does not work, meaning the pointer does not respond.
The reason I did this was because on a production version of my system I added the 3.2 screen and it worked great except for the x-axis. So I wanted to see if there was something in my system that was interfering or if this is another error. Now with a raw rasping the driver does not work at all. I wonder if the touch pin has changed since the kernel is using BCM pins instead of GPIO pin numbers?
I have exactly the same problem. I also installed a new version of Raspbian, and the LCD part works fine (except all the windows are way too large), but the touch part doesn’t work at all… I’m using Waveshare Spotpear 3.2″ V4.
I do not think that has anything to do with it. Other than power pins, the rest are communication. If it still works then you are good. No, there is something else. I do suspect it us related to the BCM pin numbering. The real question is… Why isnt the eeveloper responding? I have since abandoned this TFT because of his lack of response.
Touch actually goes through one of the SPI pins I think. Either the driver is toast with the required kernel update or the driver is using the wrong pin. It is very likely the this works well with previous raspian versions, but not with the new B+ and with the new kernel.
I am trying to use the sainsmart 2.8″ lcd sold through microcenter, using the sainsmart32_spi … seems to have the same pinouts, should I be able to get this to work? I am stuck at the white out screen on the lcd, doesn’t seem to recognize the module either.
Unfortunately I’ve tried that ( a few times actually) but the file still doesn’t exist. Thanks very much for the assistance anyway. I must be doing something wrong. My Raspian came from a Noobs installation, I’m wondering if I should try installing the OS from somewhere else. My LCD screen didn’t come with a CD or any docs so I’m completely in the dark here.
I have the waveshare 3.5 and what to use it only as a secondary screen by putting measurement data with a c program on the screen. Is there any solution?
Well figured out that step 1 was causing my problems. I’m guessing it is shutting off my hdmi feed and trying to switch it over to the SPI, am I guessing right? If so, not sure how I’m suppose to complete the rest of the steps if my hdmi output gets turned off before the LCD is actually set up to work…that sounds kind of smartass-like, which is not my intention, just looking for some clarification on what is going on in that first step as I am fairly new to this stuff. Thanks.
Anyway, I was able to do the rest of the steps with no problem. LCD didn’t work, but I am using a Waveshare 3.5, which doesn’t look to be supported yet. Mostly I am trying to play around and see if I can get it working somehow. Anyone found a way to do this yet?
I am having an issue with getting the GUI back. Every time I use startx my pi just sits there for about two minutes saying “No protocol specified”, and then it just gives up. I went through this tutorial about four times now and am not certain why it is doing this. I have the exact same LCD as is in the tutotial (WaveShare 3.2b). any help would be great.
Thanks for the tutorial. It works, but I get the boot/command line stuff on the HDMI monitor and the LCD only comes on when I do startx. Is there a way to get everything to appear on the LCD screen?
I have a Tontec 7 inch touchscreen with a Raspberry Pi 2 B. After following the instructions the touch screen is functioning but not properly… The only are that works is the upper left (and only a small area of that). I tried changing the width and height in the modules but it didnt change anything. Also the xy seems to be reversed, I changed the swap_xy to 1 but again no change on the screen.
Now the OS freezes at the emulation station loading screen, and if I connect my lcd it gives me a lot of error messages which I can only see on the 3.2 inch screen.
This was an excellent tutorial. I have gotten an output to the screen, but no touchscreen usage . I have the Waveshare SpotPear 3.2 Inch LCD V4 screen, but using Raspberry PI 2 with wheezy. Any ideas?
I filed the steps to calibrate the screen but it did not work.I think because it did not find the TFT pin, because I think the touch problem is the assigned pin to control it changed.
I actually used the driver from here http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B) , from a new wheezy build, did nothing except enable SPI in config, install driver, and change mmcblk0p2 to mmcblk0p6 in cmdline.txt and it all worked, no drama.
Advice to all who have the drivers from the (touch)screen manufacturer and cannot obtain those otherwise: you can skip everything and go to the update steps skipping the kernel and kernel modules update (as mentioned by the author) so that you don’t override the preinstalled drivers. I have a Waveshare 3.5″ RPi v3 (not the 3.2″ supported by notro’s drivers) and actually managed without any problems to get notro’s drivers make it work. However I am still reading about the xinput and xinput-calibrator to figure out how to include it as a kernel module so that I can compile my own kernel and add it there.
i have raspberry pi 2 with 3.2 inch rpi lcd v4 waveshare spotpear.i have done as per your instructions.the display is working but touch screen not working.error shows waveshare32b module not found as well as touch screen module not found messages.
Unfortunately I have lost the Touch facility on my Waveshare 3.5″ LCD Touchscreen? Can you offer any reasons as to why? I copied the Raspbian image to my Raspberry Pi from the Waveshare website first of all. The Touchscreen displays but is not reactive with any touch
I have purchased a raspberry pi B+ total kit and waveshare 3.2 TFT display online. In the package i have been given a pre-loaded NOOBS installed SD card. I did not even start anything yet. What should i do what r the things needed and how to connect the display i really want to know. I need help as i don’t know anything. Does the above solution help or will u suggest something………………..
Hi great article thanks. I am trying to get a waveshare 7 inch LCD with capacitive touch running it works with the suppled image but if you upgrade it breaks the capacitive touch. I have a sense-hat and GPS which require the latest kernel and RASPIAN image and the install program for the screen replaces the /lib/modules directory and the kernel with older ones. I need to be able to install the touch drivers into a new clean OS can anyone give me some pointers? Thanks
For anyone who have those unbranded cheap TFT touch modules and cannot get it to work with this guide, I had success on my 3.5″ with the following steps: http://pastebin.com/89qmFbPB
I have the WaveShare 3.5 (A) and cannot get it to work with the Kali Linux with TFT for Raspberry Pi. Have anybody gotten the A to work? (Not the B, theres instructions for the B already and dont work with A)
So I have the original image that came with my screen and it works fine with the LCD but my problem is that I want to use my LCD screen with other distros (at this time I am trying to use it with Kali Linux with TFT support by default https://www.offensive-security.com/kali-linux-vmware-arm-image-download/) What do I have to do to transfer the needed files from the original image that WORKS with the screen and use them with another image?
I originally bought this bundle http://www.amazon.com/gp/product/B013E0IJUK?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 with an RPi LCD V3 and no extra documentation on the specifics on the chipset. I tried with the bftft drivers but since I have no idea what to call this screen I just suppose it isn’t supported.
I’ve followed your instructions and am only getting a white screen stil. I am using the Osoyoo 3.5 inch touchscreen from Amazon. http://www.amazon.com/gp/product/B013E0IJVE?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
I’m not sure if the Jessie kernel is compatible – can anyone please confirm or not ?? Adafruit states that their setup for TFT screens are Wheezy only ; is this a different setup ??
I am using the same LCD and followed your tutorial. Have your tested the guide lately? Are you certain that it works? I see the boot messages on console but I get white screen as GUI starts.
Oct 16 17:38:48 spare kernel: [ 12.544859] graphics fb1: fb_ili9340 frame buffer, 320×240, 150 KiB video memory, 4 KiB DMA buffer memory, fps=50, spi0.0 at 48 MHz
Please check out my answer, it may help you if it works. I’m not in that case but I’m assuming that the desktop environment simply doesn’t automatically start running anymore… This can be changed in the raspi-setup
I have tried to set up waveshare 32b on my Pi B using the latest Raspian download. I learned a lot in the process using Windows Putty, Nano etc. I have repeated the setup process several times from scratch and included the corrections for possible overwriting. My Waveshare SpotPear 3.2 inch RPi LCD V4 just shows a white screen. Any suggestions?
Hi, I am using raspberry pi 2 with raspbian jessie installed. I the waveshare spotpear 3.2 v4. The above instructions are not working. and after completing the steps there was no display from hdmi or lcd. One things to notify is.: the etc/modules files only had i2c-dev and not snd-bcm2835.
I am trying to get this to work with Retro Pie 3.3.1 and the Waveshare3.2″ v4 but I only get the terminal on the lcd and emulation station starts on hdmi. to get it working with retro pie i just replaced startx with emulationstation. how do i get this to work?
Sir, Your post has very useful to me. i am using Tinylcd. but i cant get display. i am performing all the steps in your post. i cant get touch controller information from the product website and also i am using RASPberryPi B+ model. could u please give me best solution to my work. Than you.
i installed android OS in raspberry pi 2. can i use same LCD touch screen set up for android installed raspberry pi 2 which you are used for raspbian.
Is it normal the white back light during the whole process of initializing (I suspect that during the transportation trere is a deffect)? The problem is that I missed the step #1 and I performed it at the end. Unfortunately I don’t have any monitor available right now – neither “normal”, neither LCD :))))). Is it possible turning back the system or the only option is reinstallation of the Raspbian?
I have KeDei 3.5 inch TFT version 4.0 by Osoyoo. (released after January 1 2016) how do i get it working with vanilla Raspbian Jessie (do not want to install the image sent by the seller)
I’m trying to use an original Raspberry Pi model B with a cheap 3.5 inch 320×480 LCD which allegedly was manufactured to work with the Pi and has the correct fittings to fit over the GPIO pins. The operating system is the latest, downloaded yesterday and installed with NOOBS. I can’t get past step 2 of this guidance. When I reboot after using raspi-config I can see text generated as the Pi boots, then the HDMI fed screen goes blank apart from a flashing cursor in the top left hand corner. The LCD just remains white with nothing else on it. I have missed out step 1 and rebooted after step 2 and the screen functions as I would expect. Does anyone have any ideas please?
Thanks for the great tutorial. I do have a question. Once you install the drivers for the lcd are you effectively disabiling the hdmi port or is it still available to use and will the pi function with both displays. I have a pi 3
once you install the drivers it replaces the kernel by disabling hdmi output and enables it for LCD. i don’t think we have a solution to get em both working at the same time. ( you are encouraged to search for it )
Thanks for the guide, have been doing this with my son but once we leave raspi config and reboot all we get is a black screen with a flashing white horizontal line (dash). Can you help? I have looked in the comments at the end of the article but no one else appears to have this issue.
I have a raspberry pi 2 with waveshare screenn 3.5 inches. Isn’t it the same instructions. But it isnt working, all i get is a white screen, and the red led on the pi is on. The green LED isnot working.
My Rpi3 gets “ERROR: could not insert ‘spi_bcm2708’: No such device” after I enable SPI in the raspi-config.My Rpi3 is freezing on the rainbow screen after I reboot at the end of step 3. I’ve tried adding boot_delay=1 to config.txt.
if any interested, now i have a raspian image working on raspberry 3 with Waveshare 3.5, also with sdr support for dongles and FreqShow working perfectly on touch
I’d like to find the driver software for my 7″ LCD with touch (official Pi unit) so that I can use it in buildroot. I wanted to make sure this kernel is the one before I started digging further.
I started through your tutorial and completed step 3 and rebooted. After the Raspberry screen and some of the boot text on my HDMI monitor, I now have a black HDMI monitor and a white screen on my LCD. Does this mean that the bootloader was overwritten or something else is wrong? How am I supposed to enter in the proposed fixes to the bootloader, when I can’t get the RPi to boot? Do I have to interrupt the boot process at some point to reinstall the bootloader or what?
Its a script. Download and instead of running sudo ./LCD4-show run cat ./LCD4-show to simply display what it does without actually running it. The commands are fairly simple modifying a few files. I actually saved the LCD-show.tar.gz on my own server for faster future download but also for backup as it saved me tons of hours (if that’s a measuring unit for time :) )
I used this link though (smaller file ~ 50 KB, fast download) http://www.waveshare.com/w/upload/4/4b/LCD-show-161112.tar.gz and replaced LCD4-show with LCD32-show in the last line.
I’m using RasPi Zero with latest (as of last week) Jessie Raspbian. Did you run the script? If it didn’t work and you have modified other files in the process of making it work, I would recommend installing a fresh installed image on a new card and running the script. Can you suspect the screen being faulty or got “burned” in the process?
i bought a 3.5 inch tft lcd screen from banggood. and i have installed raspian jessie, the latest version, in my sd card. but when i power on my Pi, only a white backlit screen comes. there are no images or graphics whatsoever.
Will your system work with my SainSmart 2.8″ 2.8 inch TFT LCD 240×320 Arduino DUE MEGA2560 R3 Raspberry Pi ? I would like to know before not be able to back out. Thanks, Lee
I ‘m actually using a LCD Waveshare3.2” , I followed your steps to setup the lcd touchscreen for my rpi and it work but I have a problem with the resolution because if I open a repertory I do not see the whole contents on the screen .
I did a 5inch LCD for my raspberry pi. I dont use the touchscreen so i didnt have to install any drivers. It works out of the box but doesnt cover the whole screen unless you open the terminal and do:
HI I have my RPI running Pi Presents on a view sonic TD2230 Touchscreen. It all works fine, touching the click areas can navigate you thru my presentation, The problem arises when you use multitouch gestures like you would on a iPhone. Pinch or expand etc… and then all touch ability goes away. I can still control the presentation via a mouse, but I don’t get touch control back until I either relaunch Pi Presents, or if I unplug and plug the usb cable going to the touchscreen.
Could you provide me with a os image of open elec that you already built for the waveshare spotpear v4 3.2 inch touchscreen,because I cannot make sense of your website’s instructions?
In the case of the WaveShare driver, their setup script from their “LCD_show” repository will copy a device-tree overlay to /boot/overlays/ that provides most of the module config etc via boot-time device-tree patch.
After I did the step that “INSTALL THE FBTFT DRIVERS” and then reboot, my raspberry pi couldn’t boot successfully and the green light is always on, could you help me solve this problem? Thank you.
TFT LCDs are the most popular color displays – the displays in smartphones, tablets, and laptops are actually the TFT LCDs only. There are TFT LCD shields available for Arduino in a variety of sizes like 1.44″, 1.8″, 2.0″, 2.4″, and 2.8″. Arduino is quite a humble machine whenever it comes to process or control graphics. After all, it is a microcontroller platform, and graphical applications usually require much greater processing resources. Still, Arduino is capable enough to control small display units. TFT LCDs are colorful display screens that can host beautiful user interfaces.
Most of the smaller TFT LCD shields can be controlled using the Adafruit TFT LCD library. There is also a larger TFT LCD shield of 3.5 inches, with an ILI9486 8-bit driver.
The Adafruit library does not support the ILI9486 driver. Actually, the Adafruit library is written to control only TFT displays smaller than 3.5 inches. To control the 3.5 inch TFT LCD touch screen, we need another library. This is MCUFRIEND_kbv. The MCUFRIEND_kbv library is, in fact, even easier to use in comparison to the Adafruit TFT LCD library. This library only requires instantiating a TFT object and even does not require specifying pin connections.
TFT LCDs for ArduinoUser interfaces are an essential part of any embedded application. The user interface enables any interaction with the end-user and makes possible the ultimate use of the device. The user interfaces are hosted using a number of devices like seven-segments, character LCDs, graphical LCDs, and full-color TFT LCDs. Out of all these devices, only full-color TFT displays are capable of hosting sophisticated interfaces. A sophisticated user interface may have many data fields to display or may need to host menus and sub-menus or host interactive graphics. A TFT LCD is an active matrix LCD capable of hosting high-quality images.
Arduino operates at low frequency. That is why it is not possible to render high-definition images or videos with Arduino. However, Arduino can control a small TFT display screen rendering graphically enriched data and commands. By interfacing a TFT LCD touch screen with Arduino, it is possible to render interactive graphics, menus, charts, graphs, and user panels.
Some of the popular full-color TFT LCDs available for Arduino include 3.5″ 480×320 display, 2.8″ 400×200 display, 2.4″ 320×240 display and 1.8″ 220×176 display. A TFT screen of appropriate size and resolution can be selected as per a given application.
If the user interface has only graphical data and commands, Atmega328 Arduino boards can control the display. If the user interface is a large program hosting several menus and/or submenus, Arduino Mega2560 should be preferred to control the TFT display. If the user interface needs to host high-resolution images and motions, ARM core Arduino boards like the DUE should be used to control the TFT display.
MCUFRIEND_kbv libraryAdafruit TFT LCD library supports only small TFT displays. For large TFT display shields like 3.5-inch, 3.6-inch, 3.95-inch, including 2.4-inch and 2.8-inch TFT LCDs, MCUFRIEND_kbv library is useful. This library has been designed to control 28-pin TFT LCD shields for Arduino UNO. It also works with Arduino Mega2560. Apart from UNO and Mega2560, the library also supports LEONARDO, DUE, ZERO, and M0-PRO. It also runs on NUCLEO-F103 and TEENSY3.2 with Sparkfun Adapter. The Mcufriend-style shields tend to have a resistive TouchScreen on A1, 7, A2, 6 but are not always in the same direction rotation. The MCUFRIEND_kbv library can be included in an Arduino sketch from the library manager.
The 3.5-inch TFT LCD shield needs to be plugged atop the Arduino board. The Mcufriend-style shields are designed to fit into all the above-mentioned Arduino boards. The shields have a TFT touch screen that can display colorful images and interfaces and a micro SD card reader to save images and other data. A 3.5-inch TFT LCD touch screen has the following pin diagram.
I changed the Adafruit libraries for TFT: GFX , TFTLCD and TouchScreen. I join all in this one library, the library SPFD5408, to avoid problems with duplicate libraries and enables also have the original library Adafruit ready for use in other projects with another TFT hardware.
The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.
3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)
1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.
This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.
Decided to play with the 74hc595 attached in the same way as U1 for that Kedei display and I attached a Logic Analyzer to some of the output pins. Labeling is based on: https://github.com/wdim0/esp8266_with_KeDei_lcd_module/blob/master/schema.jpg. In a zoomed view it looks like this:
Downloaded your updated lib and ran your test sketch with the "tft.initR(INITR_144GREENTAB_OFFSET);" and it worked perfect for my display (starts with 3,2 if I remember right, also used "tft.setRowColStart(3,2);" with just the initr_144greentab and that also worked.

Not sure if it also would make sense to add my simple test program to the library... If I did would probably remove some of the #define/#ifdef stuff for different boards and different SPI ports... But would add comments that if you specify SCK and MOSI that correspond to another SPI port it will use that port...
Will play soon with that display... May start off by maybe trying to set up an RPI that can at least initialize the display and capture the SPI transfers, to get an idea of what the actual communications are supposed to look like... .
That Adafruit UncannyEyes is pretty nifty - may make a permanent setup for it :) Really nice since you updated the library running at 24Mhz and tested at 48Mhz as well. Still with your updated SPI library as well.
