This tutorial shows you how to connect Raspberry Pi to CAN bus. and PCB gerber files are included.
Use 0805 and SO Packages for PCB and PTH and DIP for DIY Perforated boards
Raspberry Pi Configuration
Update and Upgrade Raspberry Pi
sudo apt-get update
sudo apt-get upgrade
once that is done proceed to edit the /boot/config.txt in the terminal enter the following command
sudo nano /boot/config.txt
Uncomment the following line
Add the following lines
After editing save by pressing Ctrl+X followed by Enter. In the same terminal enter the following commands to install CAN bus utilities.
sudo apt-get install can-utils
After the above command executes successfully we have to add the below line to startup file /etc/rc.local before exit 0. This line will initialize the CAN bus interface with the given speed. In our case speed is 500Kb/s so it is 500000 bits per second
sudo ip link set can0 up type can bitrate 500000
reboot your raspberry pi using the following command
once the raspberry pi is rebooted run the following command in the terminal to check if the CAN bus is initialized successfully.
dmesg | grep spi0
once the above command is executed you should be able to see the following response
this indicates the successful initialization of the CAN bus in Raspberry Pi. otherwise please check your wiring .
