https://github.com/rusefi/rusefi-hardware/tree/main/digital-inputs/firmware firmware should be sending (and later transmitting) CAN stuff at 500Kb in order to control hardware under test

@dron0gus I've pushed something but logic analyzer does not show happy CAN outbound traffic. Is it CAN registers, pin init or something else?

CAN needs xmitter to be attached - it listens to what is transmits. I see no xmitter on photo. CAN needs at least two nodes - other end should ack valid messages. Without ack HW will go to error state or infinity transmit loop. CAN needs load resistor.
