Hi @kl3m3n,
Thanks, I know this chip, but never used it
I have done in the last 20 years almost all my projects with Bascom and Atmega and Xmega microcontrollers, but there are no libraries like in the Arduino, you have to code everything from scratch. With the Esp32 this task is easier, for this there is the lib can.h and you only need the soic8 driver for the bus.
The advantage is that the Atmega88PA is cheaper than the Esp32 but I will still think about which one to choose
Thanks for the attempt to help
Regards
