rasbian tft display drivers in stock

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:

Unfortunately, their “driver” is an SD card image containing a complete installation of Raspbian which has been preconfigured to use their display. Which is fine if you’re setting up a brand new system that doesn’t need to be a specific distro, but if you’re trying to add the display to an existing Raspberry Pi, already configured the way you want it, with software installed and data present, or if you want to use a specific distro such as Octopi, then it’s not terribly helpful.

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 ?

Yes, it may be that the screen isn’t supported. Newer screens might not have drivers yet. I do know it is possible to make your own driver but that’s above my level of knowledge :)

i have a watterott display (https://github.com/watterott/RPi-Display) and changed the device-name to “rpi-display”. i use a rsapberrypi 2 and hae the latest raspian image installed.

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

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?

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.

I remember that I plugged in the screen wrongly one time, before configuring any of the GPIO pins. Can this have damaged the screen? Still it’s weird that the display part works well and the touch part not at all.

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.

Here is a link to an updated image from waveshare. Upon install it got the display up and running, but I still do not have touch functionality. I’ve been playing around with it, but it has been to no avail…hopefully someone better at this stuff from me can get the touch working.

Great write up – worked first time for me. The only difference is by modules blacklist file was empty so there was no change needed there. Maybe to do with me being on a newer rasbian?

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.

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’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 ??

There was no disk included. I asked for drivers and was given a download link to the image file. After down loading this I tried it and still got just a white screen. The HDMI monitor locks partway though the boot. I can still log in to pi using putty from my PC.

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.

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 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)

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 )

i am sorry, but i am a naive , and i have this question, can we upload any file into it for the display? like have a software in which if i tap it gives back a feedback to the code?

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 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.

Of course. Raspbian Jessie does not come with the drivers needed to talk to the screen. See my previous comment (September 22, 2016 at 11:54 am) and follow it.

PLEASE DELETE this article. You have great power with this article showing up for so many people in their search results, and you display ZERO responsibility. This is terrible!

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

hello. I really appreciate your blog post. I have a raspberry pi 3 B. I have been unable to get my waveshare 3.2 screen to work.I am at a complete loss for what to do. I do step 2 I change fb0 to fb1 and then follow your directions I don’t get the prompt to reboot; however, I do it manually with sudo reboot. that works fine then I complete step three and that works just fine; however once I reboot from getting those drivers and when I attempt to reboot it is unsuccessful and then my whole raspberry pi will not restart. then when I power it back on it will just shut back off. I then have to redo noobs onto a new SD card I would GREATLY appreciate anyones help

it worked. but the resolution is for bigger screens. i got the menubar small, but the rest appears too big , and out of screen. the wastebasket icon is 1/6 of my 3.2″ screen. wich HAS the resolution capability too display the whole desktop. But i’m a PI newby and dunno how to adjust the screen resolution on this display. anybody?

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:

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.

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

[*]Is there any way I can extract some information of what driver has been used, or tried to use, for the TFT via that half working distribution? As far as I know, a GPIO/ SPI connection will not gather connected hardware information...

I bought a display off Amazon described as [ SainSmart 3.5" inch TFT LCD 240x320 RGB Pixels Touch Screen Display Monitor For Raspberry Pi for Model B & B+] and sold by: Sain Store. What I received is the 320x480 display you described. I am also trying to verify the model before I try to set it up.

What I would like to do is be able to "diff" a clean image and the modified image to find out exactly which drivers were used, what files have been modified for their use to be able to create a standalone install package that be used on a clean install.

It was working but was a bit too slow so, I Increased the speed After setting Everything back to normal the screen is not working properly. The display is fine , but the touch is not responding. Please help! Did I BROKE it ?

I just finished two solid days of work trying to get an HDMI LCD panel working with one of the inexpensive older model TFT LCD displays in a "Dual mode" configuration. There was a tremendous amount of help from this post, which got me most of the way there, but the infamous "last mile" still took me a while. I"m leaving some breadcrumbs here, as well as asking the group if anyone knows of a better way.

I am working on a device that uses a Raspberry Pi 4 as an embedded controller. For output, I need an 2K DSI LCD w/ its own HDMI adapter (Sharp LS055R1SX04, about $65 USD), as well as an inexpensive TFT LCD used for a basic touch user interface. The TFT LCD, which uses an ILI9341 LCD controller and an ads7846 touchscreen controller, can be had for about $10 USD. The Pi was flashed with the latest Raspberry Pi OS 32 bit then updated, so everything is current as of this writing (March 2021).

Initial configuration of the display worked with little issue. The HDMI adapter for the Sharp LCD works at 50 Hz only, so it requires custom timings. The TFT LCD uses the same controller chips as the original 3.5" Raspberry Pi LCD, so I was able to activate it with the rpi-display dtoverlay.

Booting with the above correctly revealed two framebuffer devices listed with ls -l /dev/fb*. The display initially showed as all white, then went all black, indicating correct initialization. However, when starting the desktop GUI, only the Sharp LCD showed any contents, and only it was listed as a device by xrandr.

The above configuration seems to work well. Both displays showed data. VNC showed a single combined desktop. Moving a window from left to right moved to the appropriate display as expected by the Option "Xinerama" "true" option of the server layout.

Based on claims of the above not being "ideal", I experimented with various settings. If the above file is deleted entirely, xrandr reports the Sharp LCD as the sole display. If you put the above file in place, and remove all references to the Sharp LCD (including the Device, Monitor, Screen, and ServerLayouts), xrandr correctly reports the TFT LCD, but not the Sharp LCD. I left JUST the Device sections in, but xrandr failed to correctly report one of the other.

No matter what combinations I tried, I was unable to get xrandr to list both the HDMI display and the SPI display at the same time. If all parts above ARE explicitly listed in the configuration, running xrandr reports an error that the RandR extension is not loaded. Thus I was unable to use the more advanced built in layout management of X11 using the RandR extension.

Since xrandr was INOP in this configuration, I could not use xinput --map-to-output to limit touchscreen coordinates to the TFT LCD. Instead, I settled on using a combination of touch screen rotation, and input coordinate translation:

You may be tempted to try to hack a dtoverlay that uses the ads7846 driver and specifies the x-min, x-max, etc. parameters. Don"t. I wasted a huge amount of time on this. While you can specify min/max, they apparently do NOT affect the output of that driver. The raw numbers are still reported when watching X11 input events via sudo DISPLAY=:0.0 evtest /dev/input/event0 no matter what the min/max parameters to that driver are.

The reference post noted that you can"t change the background color or image of the small display with this configuration. While that is true using the GUI, those configuration options are stored in the following files:

Xserver wants to talk to either DRM/KMS for all rendering, or goes to /dev/fbX nodes if there is no DRM/KMS available (and then Xinerama is required to support multiple displays).

With DRM/KMS X will render one "super desktop" covering all displays in their correct positions, and then tell each DRM/KMS device to display the correct bit of it. That"s how it works with dual HDMI on Pi4.

Now these SPI displays used to be driven by a driver that only exposed them as /dev/fbX nodes. They now appear to be under the tinydrm driver, so I would have expected them to show up as DRM/KMS devices. The output from modetest would be interesting to see (X can not be running when you run modetest). "xrandr --verbose" may tell you if you have vc4-(f)kms-v3d enabled. (Sorry, I don"t have one of these displays to test with)

That is how I believe things work if you were to drop 2 different graphics cards into an x86 PC - one does all the rendering through OpenGL, and then they each get told which bits of the resultant image to display.

As I mentioned in my initial post, what "works" for me is the "rpi-display" overlay. If I execute fdtdump /boot/overlays/rpi-display.dtbo on my current configuration, I see this fragement:

I"m not real familiar with this stuff (I stumbled across it while I was stuck in the mud), but I assume by these results that there are two different drivers possible: fb_ili9341 which is the framebuffer version, and ili9341 which I assume is the DRM version. If I understand how this all fits together, it appears that when I select the "rpi-display" overlay, its picking the framebuffer version due to the last line in modules.alias?

Adding "tinydrm" to my google searches revealed this Github issue: https://github.com/notro/tinydrm/issues/14, and it mentions in passing "here is an example overlay source file", pointing to the rpi-display overlay. However, when I look at the referenced source, https://github.com/notro/tinydrm/blob/m ... verlay.dts, it contains this:

I suspect that perhaps my pins may not be set up correctly for those drivers? The overlay sources seemed to indicate they were the same, but I don"t know if that is true.

I"m not sure if I uncovered an inconsistency in what is supposed to be in the distribution, or if in order to get this to work, I need to download and compile the drivers? I"ll keep experimenting, but I wanted to report what I found thus far.

Switching to the "multi-inno,mi0283qt" compatible and I get nothing. Reading the DT bindings, the backlight has been moved from being a GPIO property of the display to being a link to the backlight device driver, so it"s understandable that the backlight stays off.

On my CM4 xrandr didn"t even list the extra SPI display, whereas on x86 it is listing all the connected and disconnected displays (7 of them total!). On both systems they show up under /sys/class/drm, so it may be the way that X enumerates the displays.

So, I tried the dtoverlay you posted, and sure enough - I was also able to get a test pattern using modetest! So, that explains part 1 - the pinout is different on some of these displays.

Next, I removed my previous 99-multihead-conf file from my "/usr/share/X11/xorg.conf.d/" and restarted the desktop manager. I opened a terminal window, entered "xrandr", and both displays listed! I thought it was solved, but at that point, my poor little Pi completely locked up. I had this same problem in the past when I was trying the various DRM driver overlays. The desktop just became very unstable.

Strange that the SPI display showed up for you but not me, even if it did then crash. I"ve tried an upgrade of my RaspiOS 32bit install (although with latest kernel) and it still doesn"t want to acknowledge the SPI display through xrandr. Could you post the output from xrandr when it sees both displays?

is needed for xrandr to see the display (listed as Unknown19-1 for me, presumably as X hasn"t been built with any knowledge of DRM_MODE_CONNECTOR_SPI being 19. https://elixir.bootlin.com/linux/latest ... ode.h#L390

However it is as I suspected - we have no mouse pointer on the TFT screen, presumably as X can"t cope with one display having a cursor plane and the other not. I don"t know the best way to overcome that.

*edit*: Minor correction there. If the two displays overlap, then the mouse cursor disappears on the SPI screen. If you set them to be independent (eg "xrandr --output Unknown19-1 --right-of HDMI-1"), then X switches mode and renders the mouse cursor.

I have a Raspberry Pi 4 and an Adafruit PiTFT 3.5" screen. At some point in the past I had a screen (some random Amazon version) that acted as a second screen with its drivers installed. Ie. in the Screen Configuration tool it showed up as a separate display.

There is a KMS driver for HX8357D in https://github.com/raspberrypi/linux/bl ... /hx8357d.c for what appears to be an Adafruit display, but AFAIK there isn"t an overlay for it at present, nor the driver being built into the kernel.

If it is anything like the 2.8" PiTFT , all I could get it to do was either 1) Mess up my monitor resolution to match it, or 2) terminal on both it and my monitor.

First, with both displays enabled the system is slow and almost impossible to work with. Any ideas how to improve this? (I don"t really need both in operation at once, so I am thinking maybe a script to swap between them?)

The pitft35 is really slow at 32MHz and if vc4/HDMI has to wait for pitft35 to complete its pageflip before vc4 gets its turn, both displays will run at maybe 8-10fps?

The fbtft driver calls the property "rotate" and the DRM driver calls it "rotation". The DT overlay needs a fix to the rotate parameter like it"s done here: https://github.com/raspberrypi/linux/co ... 3e881ca468

When following the same setup that works on the 32 bit system, the 64 bit becomes stuck in some kind of display reboot loop as soon as the 3.5" driver is installed. If the HDMI is unplugged completely it is possible to use the 3.5" screen normally, but if the HDMI is plugged back in the 3.5" screen and HDMI displays both seem to alternate rebooting and become unusable. Even the VNC display is no longer available. If the HDMI is unplugged the VNC display returns.

As it is an RGB interface you can directly connect it to the Raspberry DPI interface (https://www.raspberrypi.org/documentati ... /README.md) without "glue logic".So, what you will need is an adapter board which converts the 40pin GPIO (2.54mm pitch) interface to 0.5mm FFC. In addition you will need to input the timing (page 10) to let the RPI now how to drive the display.

This is what the above setup looks like "in action". That 5.6in display is 640x480pixels native resolution. I"m running KMS graphics driver which allows me to scale my desktop to 1024x768pixels which still has a good readability on the display (xrandr --output DPI-1 --primary --scale 1.6x1.6)

Note: DSI to RGB chip used on the RPI display is EOL; so there is the chance that we will see a new official display in the future (but also a risk that RPi decided to make a last-time-buy with huge quantaties in orderto be able to ship longer).

if you did not/been unable to salvage that component from your display donar device you need to find a new one (extra costs, different specs, ..). And..there is still the risk the backlight fails on first start attempt!

Simplest use of a DPI display is by adding the timing to `panel-simple.c", write an overlay which uses it, compile everything and then add the overlay to config.txt. No need to write any driver.

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 ).

Finally got my whitescreen issue resolved with a loooong processes of a clean headless install of raspberian stretch and the drivers as outlined above. I have no monitor other than this screen. I now have an issue continuing with my project whose first step is to do an update and upgrade. This reverts me to the whitescreen issue again. Can I presume that every time I do an update I also then need to reinstall the driver? What else does the driver install overwrite?

this can make bigger sales $$$$ if the creator gives a driver that can solve the problem or show how to enable the HDMI for extended display or double display mode activated function.

“ATTENTION” in the instructions they wrote >>./LCD_dhmi<>HDMI to R-pi display<<: it is just to reinstall the driver again, I need to execute the point 5) through the point 7) again.

this is a bit annoying to change from "R-pi display to HDMI" or "HDMI to R-pi display", if you want to give a public presentation or if you make projects involving the HDMI connector at the same time using a extended display or cloned display or projecting video or images PNG.

Please help: bought a small screen http://www.wvshare.com/product/3.2inch-RPi-LCD-B.htm, anywhere in the manual says that there are no problems with connecting and setting no. However, I am the third day I bet that this device has earned. As I understand it, before you had to download the modified firmware image rasbian and pumps a driver. Now like latest firmware supports such displays, just something where you have to uncomment it in the configuration files. Help please, I beg you!

Won him away. I have found the firmware, which the Chinese hid. Tomorrow I will lay out on Yandex drive and throw a link here, so that others are not obsessed like me. TFT earned immediately. By the way from 2.8 German, too, must go, there is the same pinout.

And, of course, here https://github.com/notro/fbtft/wiki (Image Download section) because this is what I found inside issue.txt file on my microSD after flashing it:

I also have the waveshare tft lcd, but I do not want to use the image provided by the supplier (which in my case did come with the product) and I do not want to use the screen as a replacement for HDMI. I want to be able to send images to the screen.

In this video tutorial http://www.youtube.com/watch?v=dUZjzQuTNX4 , for example, Ben is trying to find the voltage threshold where his display goes down. For a split second @ 4:59, one can see that there is no image against a completely white background. The perfectly operational LCD simply browned out...

Because of the change of 3 pin mappings between rev1 and rev2 you have to change the GPIO signal used for the reset of the display. With version 3 of the display the pin 13 is used for reset. On rev2 boards this pin is routed to GPIO27 but on rev1 boards to GPIO21 (see http://elinux.org/RPi_Low-level_periphe ... .28GPIO.29).

btft_device name=flexfb gpios=dc:22,reset:21 speed=48000000In order for the display switch script (LCD32-show-sys-v3) to copy a corrected config file change the respective file in the subdirectory of the switch script (in my case: /home/pi/DVK512/LCD32-v3-show/etc/modules).

I need help. I have the 3,2" touch screen tft display rev.A from ebay. I tried everything to get it to work. The seller does not respond to my messages.

The same here, I have a model B pi. I tried the DVD_DVK512_CN_EN and the mentioned images on this thread, always it only displays a rainbow sort of screen on the hdmi out.

If you want to install the LCDs on a clean version of Raspbian or Rasbmc, I have written up a step by step guide with a beginner in mind on how to do it. It took several days of research to find out exactly how to install the drivers and get the touchscreen configured and calibrated correctly, but I have it working nicely. If you want to save some time and headaches, check out the article here: http://www.circuitbasics.com/setup-lcd- ... pberry-pi/

Today we are going to learn how to interface LCD TFT display using SPI interface with Raspberry Pi and also how to change the orientation of the screen. The SPI display comes in different sizes and speeds. Here is the list of all different type of RPi display with SPI interface from waveshare.

As I am using the 3.2-inch display without high-speed SPI and with Rasbian OS I am using this comment to install the driversudo ./LCD32-show.below is a table of different installation comments for different LCDs and OS.

There is a specific way in which the display must be connected to the pi. This detail is provided in the rpi-display overlay in the /boot/overlays folder.

In the rpi-display@0 section you will see details of pin numbers. The numbers provided here are in hex format. You will need to convert them to decimal.

The first part maps the boot console to frame buffer 1. Then we change the font to a small size and remove the raspberries that appear on the top left of the screen while booting. Reboot and you should see the console appear on your screen. If you have an external HDMI screen plugged in while doing this, you will notice that the boot messages appear on the TFT. The HDMI display goes to the splash screen and desktop after booting.

If there are problems with wget, then use curl for the download: $ curl -k -L -o rpi-display.sh https://github.com/watterott/RPi-Display/raw/master/rpi-display.sh

Parameters for the ADS7846 overlay (in /boot/config.txt) when the RPi-Display overlay is not used.dtoverlay=ads7846,cs=1,penirq=25,speed=2000000, swapxy=0, pmax=255, xohms=60, xmin=200, xmax=3900, ymin=200, ymax=3900

Note: Only first generation RPi-Displays before April 2014 use 9-Bit SPI.$ sudo modprobe fbtft_device name=mi0283qt-9a gpios=reset:23,led:18 speed=32000000 rotate=270

Add the following Kernel arguments to /boot/cmdline.txt:fbtft_device.name=mi0283qt-9a fbtft_device.speed=32000000 fbtft_device.gpios=reset:23,led:18 fbtft_device.rotate=270

For better accuracy a touchpanel calibration can be done with:xinput_calibrator$ sudo DISPLAY=:0 xinput_calibrator --device "ADS7846 Touchscreen" --output-type xinput
