@RobertCNelson My shcematic pdf (https://drive.google.com/file/d/1Bd_lXEkywucwcdcvqsL_ua7Hfz1413MB/view?usp=sharing) is a little different from yours. Is jp8 and not j8. But I know it must be the same, my doubts are below:
Question 01 : The 3.3v and 5.0v pins are already configured or should I proceed similarly to the gpio40?
Question 02 : Similar to the question above, only referring to GND
Question 03 : JP8_40 is can_rx and jp8_18, too (according to my pdf) And not can_rx2 and can_rx1.
Does this change anything when configuring?
Wouldn’t it be better if I use the jp8_34, jp8_35, jp8_36, jp8_37 that are already defined with gpio and not as can_rx ???
