COMMUNICATION
Figure 14: Main board partial right side view
The development board off ers a single DIP switch located in the CAN COMM. section,
which is used to specify whether the RB2 and RB3 pins should be used as GPIOs or
they should be connected to the CAN transceiver circuit as CAN TX and CAN RX lines.
CAN connectivity is provided only for MCUs installed in DIP28 and DIP40 MCU sockets:
RB3/RB2 (DIP28, DIP40) (10)
GPIO (up): Allows the RB2 and RB3 pins to be used as GPIOs
CAN (down): Connects the RB2 and RB3 pins to the CAN transceiver circuit
The development board can be connected to the CAN Bus by using the 2-pole screw
terminal (11), located in the CAN COMM section. Please note that the CAN H and
CAN L diff erential signals need to be properly connected to the CAN Bus, else no CAN
communication will be possible.
