CAN SDK
Our Boards Test Link
- Arduino + MCP2551 CAN Module <-> Raspberry CAN RS485 Shield <-> USB-CAN sLCAN Board
- Any of these two will work.
EDCAN Test
Use contact software, communicate with Raspberry PI CAN (SN65HVD230DR)

config SPI CAN: edit in file /boot/config.txt, and add following line
dtparam=spi=on dtoverlay=mcp2515-can0,oscillator=12000000,interrupt=25,spimaxfrequency=2000000
Reboot and check if installed: dmesg | grep -i '\(can\|spi\)'
