The default software supports 2 LIN message frames:
●
PID = 06, size = 2 bytes: This frame is published by the
GUI to control the ATAB1634 board, e.g., to turn LEDs
ON or OFF.
●
PID = 03, size = 4 bytes: This frame is subscribed to by
the GUI to obtain the status of the ATAB1634 board,
e.g., to find the current potentiometer reading.
If a response is not received for a message that the GUI
subscribes to, a time-out error is displayed for the frame.
