Small physical size of the screen, so we recommend you to use 480 * 320,800 * 480,800 * 600 resolution display, it will be blurred if you use too high resolution, and the module power consumption will rise.

Understanding that many people have problems configuring their Kuman TFT display on the Raspberry Pi together with RetroPie, I have decided to make this step-by-step of how to install the Kuman TFT 3.5" display which you can connect directly to the GPIO ports of the Raspberry Pi and run your applications. A lot of people have been buying this Kuman display from Amazon and other online markets for its economical price but it is not an easy display to install for certain applications, compared to other displays that come with integrated HDMI ports that will surely be a lot easier to manipulate and start working.

I advise you to buy a GPIO cable or a ribbon cable to connect the display to the Raspberry Pi, because sometimes (and it happened to me) at the time of manipulating the display and fitting it on the pins of the Raspberry, the screen being so the thin can be broken easily.

Verify that you have RetroPie burn on your SD Card, if you have not already done so, click on the following link, install it and come back here to continue the steps.

Next, copy the following code to download the best driver from Github:git clone https://github.com/goodtft/LCD-show.gitchmod -R 755 LCD-showcd LCD-show/chmod +x LCD35­-show./LCD35­-show

If, after installing, the screen is a mess together with the TV missing icons or words, please connect via SSH to your Raspberry Pi and run this command:cd RetroPie­-Setup/sudo ./retropie­-setup.sh

The previous command will open the Retropie configuration file where in the end you have to look for something like SPEED and FPS and change the values to something like:dtparam=audio=ondtoverlay=tft35a,speed=62000000,fps=40,rotate=90#dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=25000000,fps=20,keep_vref$gpu_mem_256=128gpu_mem_512=256gpu_mem_1024=256overscan_scale=1

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.

Rotating the screen to the proper orientation proved challenging. The config.txt rotate commands don’t work with the raspberry pi4. I couldn’t get the xorg configuration to rotate the display. When I added kernel commandline parameters to rotate the display, that worked for the initial verbose boot screen… but once KlipperScreen loaded, it was the wrong orientation.

At this point your Octoprint should be loaded but your mouse and touch screen will probably be moving backwards. In the newer (Jessi, Buster) versions of Raspbian they change input control from evdev to libinput. You need to install evdev or it will ignore you 40-libinput.conf configurations.

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.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

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.
