- Use raspi-config to make sure I2C and SPI are enabled
- Add BCM2835 modules to config
sudo vi /etc/modules i2c-bcm2708 i2c-dev
- For python support install these libraries
sudo apt-get install python-pip sudo pip install python-can
- Make sure boot config file is setup
sudo vi /boot/config.txt dtparam=spi=on dtoverlay=mcp2515-can0,oscillator=8000000,interrupt=25,spimaxfrequency=1000000
- Reboot and make sure CAN and SPI devices show up
sudo reboot dmesg | grep -i '\(can\|spi\)'
