The socket CAN sample is a server/client application that sends and receives raw CAN frames using BSD socket API.
The application consists of these functions:
- Setup function which creates a CAN socket, binds it to a CAN network interface, and then installs a CAN filter to the socket so that the application can receive CAN frames.
- Receive function which starts to listen the CAN socket and prints information about the CAN frames.
- Send function which starts to send raw CAN frames to the bus.
The source code for this sample application can be found at: samples/net/sockets/can.
Building and Running¶
Build the socket CAN sample application like this:
west build -b <board to use> samples/net/sockets/can -- -DCONF_FILE=<config file to use>
Example building for the nucleo_l432kc:
west build -b nucleo_l432kc samples/net/sockets/can west build -t run
