Installing Raspian and enabling CAN bus

• Download Raspian Lite from: https://www.raspberrypi.org/downloads/raspbian/
• Flash image to micro SD card, for example using: Etcher
• Add empty text file named ssh to the boot partition of the micro SD card, this enables ssh communication with the Pi.

• Insert the micro SD card to the Raspberry Pi and power it on. Use an ethernet cable to connect.
• Access ssh on the Raspberry. Default username is pi, password is raspberry, and hostname is raspberrypi.
• Run sudo raspi-config and change password and timezone. Perhaps also run an update.

• Run sudo raspi-config and enable SPI
• Add these lines to the end of /boot/config.txt:

dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25
dtoverlay=spi-bcm2835-overlay

• Add these lines to the end of /etc/network/interfaces for CAN to automatically start at boot with bitrate 125kbps(used by Torqeedo Interface Card):

auto can0
iface can0 inet manual
pre-up /sbin/ip link set can0 type can bitrate 125000
up /sbin/ifconfig can0 up
down /sbin/ifconfig can0 down

• Reboot

• Add user to dialout group

sudo usermod -a -G dialout $USER

• May also need to add user to tty group.

sudo usermod -a -G tty $USER
