I'm currently trying to interface USB Peak Can with Spark fun can bus shield.
So I'm trying to test sending data from the Shield to the USB Peak Can bus, but nothing is sent at all, the same for receiving.
Here is the pin diagram for Peak USB Can Pin assignment D-Sub
Pin Pin assignment
1 Not connected / optional +5V 2 CAN-L 3 GND 4 Not connected 5 Not connected 6 GND 7 CAN-H 8 Not connected 9 Not connected / optional +5V
CAN-L, CAN-H are connected to the shield CANL, CANH, plus the ground common.
I'm not sure If I should add a terminal resistor, but if it's necessary, how would I connect, can I have a schematic diagram please ?
