Hello.
ESP32
I already managed to controll waveshare 4.2inch eink display with arduino ide and GxEPD. Trying it with ChiliPeppr. Any libraries? Can i use SPI in this IDE (ie custom firmware)?
Thanks

The firmware available for download in this workspace has the kitchen sink in it, so it supports SPI and I2C. The docs that are linked to for ESP32 show the SPI and I2C support, so 100% of the docs are supported in the firmware.
