I have the same LCD as you do. i was wondering if you could help me with the pinout of the LCD… valdodov has a different lcd and his schematic doesn’t transfer well to the one you have i think. is there a schematic that you could post or tell me where BL_CNT is connected from the 4094s to the LCD?

the Spi (MOSI) is buffering 32 bits (when the strobe is off) then the SPI (MOSI) waits for 32 spi cycles (When strobe is on ) . Am i understanding correctly .

I’m thinking of a Python or C library, or better yet an optimized binary that you can pipe the raw data to from another process to send it to the screen…yes to all the above. You just need to write to the framebuffer

Where did you find the pin out for the sainsmart touch screen? We were looking at the following data sheet and it has different pin assignments. Please help us clear up this confusion. Thank you!!the display in your datasheet uses ILI9325 driver chip for the display.

We were following the instructions on github/notro/fbtft/wiki but I think I just realized that that’s a different method. So in order to install the kernel/modules should we use the compiled files on Voldadov’s site? If so, how do I copy those drivers? I extracted them to the desktop then did:

Finally got it working! (Sort of) Must have had a few dead rails on my breadboard because I purchased an new breadboard, and lo and behold, our screen works. We can see the boot information and there are no errors, but it stops at a blinking command prompt, but I cannot type with the keyboard, and it does not boot into the desktop. So we’re kind of stuck at a blank command prompt. Is there any code I can edit to make it boot into the desktop? Or is there any way to make the keyboard work?Do you have the keyboard directly connected to the Pi? Or are you accessing the Pi via SSH from another PC?

sudo mplayer -vo fbdev2:/dev/fb1 -x 128 -y 160 -zoom fileWe have the keyboard directly conneected to the pi. Should we be using SSH? And we can get it to work by deleting the

I am working for several months with the Raspberry and I also know a few experminete performed. Well me too interested this project. I myself already so bought a 3.2 “touchscreen, but I dunno exactly how to wire the. Could you maybe make a wiring diagram. That would be very nice.For example, with http://fritzing.org/

We are following your circuit for interfacing the raspberry pi with touch screen. We have currently wired on a breadboard and currently working on a better consistent solution like having it on a PCB.

-What driver?I am using the same chips and TFT as you are using. The driver i am using is Raspbian. I am using a breadboard but i have checked the circuit multiple times using a multimeter to confirm the connections so i am not sure if that is an issue.

Thank you for your help. I found a small connection issues with one of the ribbon cables i was using from the raspberry to the breadboard. Now that it is fixed everything works great without any problems. Thanks.

I have a question about kernel: I install the Rpi version 2014-06-20-wheezy-raspbian, kernel version 3.12.25+ #700 after upgrade, but after apply valdodov, kernel come back to 3.6.11 #41 …

Thanks for the Kernel but on my Pi is nothing to go the Display is not working. I have the Sainsmart 3,2 TFT with the Modul that is in the Video (selfmade) but i find no error in my circuit board it is with 3 74HC4094 and 1 74HC4040 . ? Is there a Kernel that Support this Version with no updates.?

anyone a idea where this vertical flashing lines come from?It has been awhile since I have looked at this version of the display with the above SPI interface.

You can also try and force the 4040 to go faster my connecting it to 5vi found the issue…. above GND is a Pin named “VCC” – it was not connected (and looking at your schematics, it didn’t look like it has to be connected to 5v)

I have a couple of these displays. They are different from the Sainsmart, not the SSD1289 controller. It"s the ILI9327, the pin out is different from the other projects I have seen. It looks like it needs to be 16 bit parallel, and the notation on the board makes it hard for us NOOB"s to make the jump to know where to put the sinc signals.

Hey I don"t know if this helps but I found this WaveShare tft that looks exactly the same as the Eleduino tft (only difference is the WaveShare logo and one less button than the Eleduino) on Amazon with this link provided: https://s3.amazonaws.com/ttbox/3.2+Screen.zip If you"re using your own system image it says you need to install WiringPi and C libraries for BCM2835 otherwise it says to use the image provided.

I"m thinking about getting the Eleduino tft screen as well but not before doing a bit of researching. There wasn"t much documentation I could find so this is as close as I"ve gotten to any type. I know it"s not the same brand but they look identical and are both made by the same company SpotPear so I figured this must be what comes included on the disc provided for the Eleduino.

hello i recently purchased a 3.2 tft touch screen for raspberry pi from your company. The product did come with all of the specified parts described but i am having a major problem using the screen. I assembled the screen onto my raspberry pi b+ and I flashed the image that came in the dvd enclosed properly but the the screen only displays a white screen. I gave the device about 4-5 minutes thinking it might take a minute before it displays anything but no luck so I restarted the rpi with a monitor attatched to the hdmi port and all i get is a color boot screen on the monitor. so then I installed the required C libraries on a standard raspbian image without problems and still no luck. Any help would be greatly appreciated and thank you in advance

The documentation I described earlier says to switch the 3.2 tft display to HDMI open the LX Terminal and type: HDMI-SYS-SHOW then wait several minutes while the system loads the driver. When finished the RPi will reboot automatically then wait about 30 sec for info to display on the LCD and enter into startx interface. To do the opposite (HDMI to 3.2 tft) type: LCD32-SYS-SHOW and wait for the designated time. I don"t know if this might help you as you say the screen is all white. I don"t own one yet to test any of this. It could be a defective unit though. At least they said they"ll set you straight with a replacement. Have you contacted them back yet?

Hi all, I need help buy a lcd tft Waveshare 3.2, and I can not make it work, I have reviewed the web in search of the image to download, but do not get it. If anyone can share what I appreciate

If you want to install the LCDs on a clean version of Raspbian or Rasbmc (no image needed), 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/

Interfacing a Touchscreen LCD with a Raspberry Pi is very useful as this setup can be used to develop Raspberry Pi based stand-alone systems like Weather Monitoring Stations, Security Systems, and Camera Interfacing etc. Adding a Touchscreen to your Raspberry Pi opens up doors to a lot of projects as well as increases the portability of the system.

Having a nice LCD Display on your Raspberry Pi can allow us to make complex projects like a media center, personal computer, smart phone, tablet, etc.

There are different types of Touchscreen LCDs available in the market today for Raspberry Pi from different manufacturers with different screen sizes, resolutions, operable with stylus, etc.

In this project, we will see how to setup an LCD Touchscreen on Raspberry Pi. For this project, we have chosen a WaveShare SpotPear 3.2 inch RPi LCD V4 touchscreen type LCD display.

NOTE: We’ll show you how to setup WaveShare 3.2 inch LCD with Raspberry Pi using the official drivers and also the provided Raspbian image. We tried to install this using our own Raspbian Jessie and Drivers but there were some problems. We will definitely update how to install any type of LCD with Raspberry Pi very soon.

There are different manufacturers of Touchscreen LCD displays for Raspberry Pi like Adafruit, Newhaven Display, Haoyu, Freetronics, WaveShare, Watterott Electronics and many more but we thought Touchscreen LCD displays from WaveShare for Raspberry Pi are affordable, easy to use and comes with drivers and their own version of Raspbian OS (our thoughts and might differ with other users).

There are many variants of Touchscreen LCDs from WaveShare like 2.8 inch, 3.2 inch, 3.5 inch, 5 inch, 7 inch, 10.1 inch etc. For setting up an LCD Touchscreen with Raspberry Pi, we are going to use a 3.2 Inch WaveShare SpotPear LCD.

This particular LCD Display has a Resistive Touchscreen with a screen resolution of 320×240. It is interfaced to Raspberry Pi using SPI protocol. The LCD module has 3 user button that can be programmed to do additional functions.

The Wave Share 3.2 inch display can be directly plugged in to the Raspberry Pi on the GPIO Pins. It uses 26 Pins of the available 40 pins of the Raspberry Pi’s GPIO. Out of the 26 pins used, some do not have any connections (NC – No Connection).

First we will see the Pinout of the Raspberry Pi GPIO and then we will see the relevant pins required to connect LCD using SPI. The following image shows the pin out of Raspberry Pi’s GPIO Pins.

In these 40 pins, the connector on the back of the WaveShare 3.2 inch LCD has 26 pins (2 rows with 13 pins in each). The following table gives the list of pins we are going to need to interface the LCD with Raspberry Pi.

Now that we have seen the basic information about the WaveShare Touchscreen LCD module, we will proceed with the setup. There are two ways you can setup the LCD: 1. Use your own OS (Raspbian) and install the drivers or 2. Use the provided OS image file (it can also be downloaded) and do a fresh install of the OS.

If you want to test whether the LCD is working or not, you can go with the OS image provided by the manufacturer of the LCD. It is usually given in a CD or can be downloaded from the official website.

Write this image file on to the microSD card, insert it into Raspberry Pi and boot the Pi with LCD inserted on the Raspberry Pi. The Raspberry Pi directly enable the Touchscreen LCD display.

But, if we want to use our Raspberry Pi with any OS of our choice, like Raspbian Jessie for example, first thing we need to do is download the drivers for the LCD Module from the website.

You can also download the image file from this site. There are two versions of drivers in the website. We have downloaded the first one (LCD-show-170703.tar.gz) and put it in the Desktop. Do not unzip or unrar it.

Assuming you have already setup the Raspberry Pi using the headless setup (no monitor or keyboard), we will proceed by copying the downloaded driver file in to the Raspberry Pi’s memory (microSD Card).

Download the WinSCP and install it. Once the installation is completed, open the WinSCP application. As soon as you open it, you will be asked to enter the details of the session. Select File Protocol as SFTP (SSH File Transfer Protocol) and enter the IP Address of the Raspberry Pi in the Host name field.

Enter those details as per your settings (if default settings are unchanged, username is pi and password is raspberry). After successful login, you will enter into the main screen of the WinSCP application.

The screen is divided in to two halves and the left side the host computer (in our case the Windows PC which we are using) and the right side is the SSH connection (Raspberry Pi).

On the left side, go to the folder where you have downloaded the LCD Driver file. In our case, it is located on the Desktop. On the right side, go to home/pi folder. Drag and drop the LCD Driver File from left side to right side.

You will get a message about file transfer and just press ok. The file is now transferred from my desktop to Raspberry Pi. You can now disconnect the Raspberry Pi from WinSCP (Session  Disconnect).

Now, open Putty and login in to Raspberry Pi. After logging in successfully, we need to extract the contents of the LCD Driver file. To see the list of files and directories, you can enter the following command and press enter.

Now, to extract the contents, enter the following command. This command will extract the contents of the file LCD-show-170703-tar-gz to the present folder.

A new folder with name “LCD-show” will be created in the process. We need to go in to that directory. For that type the following command and hit enter.

Now, since our WaveShare LCD Module is a 3.2 inch one, we need to install the drivers specific for this LCD Module. For that, enter the following commands one after the other.

After entering the above commands, the installation of the LCD Touchscreen drivers will be initialised and the Raspberry Pi will automatically reboot. If not, you reboot the Raspberry Pi and after booting up, the Raspberry Pi will directly display on the LCD.
