I have been trying for several weeks to get my Portenta H7 with expansion board to read or write to a CAN bus. I have been using the read/write examples in the machine control library with no success. I have tried connecting my transceiver to both the CAN 0 and CAN 1 connections on the breakout board because I cannot tell which one the example program uses. However with either example and either CAN connection I have been unable to get the Portenta to read or write to a known good CAN bus with proper termination resistors. Has anyone been able to get CAN working with the Portenta's built-in CAN controllers? Thanks in advance!
Hi @rlr_jcn ,
I have been trying to use the Adafruit CAN pal TJA1051T/3 with the Portenta H7 to read regular CAN messages but couldn't figure it out. Could you maybe help me out with some source material or documentation to get going?
Thank you so much
