None of those seemed to make a difference so I connected it to my RPi that’s running HA. I tried a reset, different USB cable/port, resetting the board, and holding the boot button on connect (not sure what’s supposed to happen here, but nothing changed). Try resetting your device or holding the BOOT button while selecting your serial port until it starts preparing the installation. Source: How to Install Kuman TFT 3.I just purchased this ( Overview | Adafruit ESP32-S2 TFT Feather | Adafruit Learning System) to try out ESPHome.įor the initial configuration, I tried to connect to it directly from my PC using USB and got this error:įailed to initialize. I hope these steps will help everyone to configure the display with their Raspberry Pi in Retropie and in general. This configuration works for me personally, but feel free to change the parameters to the one that best works for you.
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=onĭtoverlay=tft35a,speed=62000000,fps=40,rotate=90 Remember to connect via ssh to your Raspberry Pi to run this command:
If you start to play you will notice that the game is not very fluid on your screen, the way to fix this is by making some changes at the Config File. This will take you to the main menu of RetroPie, where you must choose: update all installed packagesĪs soon as the installation is complete, restart the system and you will have your screen working together with your TV. 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/ Restart and you should see the content on your Kuman 3.5″ display. Next, copy the following code to download the best driver from Github: git clone After that let the system install and do not restart. Now press Y to continue and select the best options in the menu just pressing 1 or 4. Start with: cd curl -O -Pi-Installer-Scripts/master/pitft-fbcp.sh
