Hi,
I am working on a can project using the EPS32 device and a can transceiver, I’ve found many libraries online but they seem to not work for me for some reason. One of the, in particular which seemed to be the most complete one: GitHub - sandeepmistry/arduino-CAN: An Arduino library for sending and receiving data using CAN bus..
Whenever I try to compile it, I have these parameters undefined, any ideas of what I can do about it?
