Raspberry Pi with ultrasound example in C
The code is meant to be run using two Raspberry Pi. Each Pi is connected to a MCP2515 module. One Pi is connected to a HC-SR04 ultrasound sensor. The sensor calculated distance to an obstacle is transmitted as a 32bit float. The float is serialized using canard_dsdl.h. At the reciving end the float is deserialized and the distance is printed to the console.
