this is my playground fro the Raspberry Pico rp2040
it uses to following hardware
MSH-4.0inch Display B
4x4 keypad
The goal is
- get the dispaly to work
- react on touch
- read keypad via PIO
Interaction with LCD is done with the help of https://github.com/Bodmer/TFT_eSPI. After calibration, the cal data are stored in the EEPROM of the rp2040 and can be reloaded on startup.
