Hi
thanks a lot in advance for any advice. I’m new and have never programmed a Touch Screen. Only the classic and boring 2x16 and 4x32 display.
My project could split into 2 different options:
HW Rasperry + Tool CodeBlocks (C++) and LittlevGL library
HW STM32 Nucleo + Tool System Workbench for STM32.
For each, I would need a Touch screen. I would like totally the second option, but it is not up to me.
Can anyone recommend me one a Touch screen RGB 4-6 inches for both options? I don’t have experience on it and on LittlevGL.
Thanks
I am not sure what kind of touch you are using but if you are using resistive touch with 4 wires there is a library
adafruit_touchscreen.cpp
you can use that library and port it for your stm32. It is completely working. and for adc in your stm32, I recommned you to use two different adc and use it in injected mode.
and last thing use calibration method
