The 3.2 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.2” display with 320x240 16bit color pixels and resistive touch screen. The LCD is well mated with Pi board and interface with Pi via the high speed SPI port, and support console, X windows, displaying images or video etc. It also provides 4 press buttons for user defined functions.

RPi LCD needs to use a SPI interface, but in the original image file of Raspberry Pi, the displayer is driven via a HDMI port. So the original image is not applicable for RPi LCD, and you should install the LCD driver to your Pi or use the Ready-to-use image file provided by Sainsmart,click here.

Download the LCD driver and extract it to your Raspbian OS (e.g. copy the driver to your Pi by sftpor using U disk). Then run the following command via putty:

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the offer image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually with

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.

SainSmart 3.2" TFT LCD Displayis a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

I am on a steep learning curve, hence the simple questions. I assume given the appropriate scripting the Raspberry will boot straight to the screen with out the need for keyboard inputs

Reason: The hooks on the backight of ER-TFT032-3.1 is always complained by most customers for inconvenient assembly. So we cancel the hooks in the new version of ER-TFT032-3.2.That"s the only difference for these two versions.

ER-TFT032-3.2 is 240x320 dots 3.2" color tft lcd module display with ILI9341 controller and optional 4-wire resistive touch panel and 3.2 inch capactive touch panel with controller FT6236,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8/16-bit parallel,3/4-wire serial interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.2"TFT Touch Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

Has anyone gotten the buttons to work on the SainSmart 3.2" TFT screens for Raspberry Pi? I have some ideas to make them call commands or Python scripts, but don"t have any documentation from SainSmart as to how they work, such as which GPIO pins they are mapped to. I suppose I could experiment and find out, but that"s why I"m asking the forum first.

The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Get Kamal’s source which has the patch for ST7735R controller and the branch for the kernel that is used in 2013-02-09-wheezy-raspbian, which is 3.6.y;

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace ‘raspberrypi’ below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder ‘mark’… yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

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?

Thanks for the schematic, I will try and see if this works. if not, its probably some issue with the kernel. Also, if it is due to the kernel… was the kernel files just supposed to be copy pasted into the specific folders? was i supposed to enter anything in the command-line/terminal to get the display to start working?Just need to overwrite what is on your SD card.

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 .

That’s great and all, but is there a way to push raw image data (bitmap images, video, etc) to this display without making it an active tty/X display? Something that can run headless and have data pushed to it from a remote ssh session, cron job, etc?

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.

If you cant display the image or you get the same error, I would recheck the wiring. Are you using a breadboard?No /dev/fb1 is not present. We are using a breadboard and just rechecked all of the wiring. The wiring looks good, but we are missing the filter capacitors (can’t get them till tomorrow) would that be the issue? It looks like a few people had this same issue but there is no definitive solution. What exactly is error -22?

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.

hae the boot screen with white lines ….. by starting xbmc screen gets smoothy to white and finish….. think its wrong screen size… how can i set the resolution for all in to 320×240?hm…. can see the boot rows…. sometimes…….

sometimes with blue stripes…. sometimes not all letters only a small stripe….. and agter getting message ???52×21??? screen goes slowly white……I think……. i have killed the display :-p … ok next one…

-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)

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!

I used a SainSmart 3.2" TFT LCD Module touch screen display. I believe it"s a re-badge or clone of the WaveShare32 TFT touch screen display. I got it from my local Micro Center.

First I disconnected the flex cable and separated the driver board from the actual TFT display. They"re held together with double sided mounting tape, so that part was easy.

Then I used a dremel tool to cut right along the 4 slim tactile button switches on the side of the driver board. This both resized the width of the board to the same width as the display as well as removed the buttons.

Then I soldered wires from the appropriate pinouts directly to the GPIO on pi zero based on the pinout specs available on the page linked above. The manual linked on the same page also has more pinout details. I put electrical tape on the opposite side of the pin holes on the driver board to prevent any contact with the back of the TFT display.

Lastly, I removed the mounting tape, reattached the driver board to the back of the TFT display using double sided masking tape to reduce the thickness of the display, and reconnected the flex cable.

Drivers are included in raspbian jessie which makes enabling the display so much easier. You simply have to place the parameters below into the config.txt file in the boot folder.

The first set of parameters setup the display resolution. The second to last parameter enables SPI. The last parameter specifies the hardware overlay for the display so the correct kernel modules are loaded along with maxing out the speed and frames per second for the display. I also had to specify rotating the display 270 degrees since I have the display turned around for shorter wiring between the pi zero and the display in the GBA case. More info on the software side of things can be found here.

Since The SainSmart 3.2" TFT LCD Module has a resistive touch screen , I highly recommend you also blacklist the ads7846 touch input kernel module. Otherwise, the kernel will get continuous interrupts from any pressure between the touch screen and the back of the front of the GBA which will affect both input and game performance.
