Building an FM Radio Station with Go
summary
Goal is to push TMC traffic data into a car’s nav by building an FM station with Go: a Raspberry Pi (3/4), an Si4713 chip FM transmitter (I2C, RDS/RBDS, ~10 m range) and an LCD. A custom Go driver is written because only C/Python drivers exist, and integration uses the Gobot framework. Audio goes through the transmitter jack; reception is validated with an Airspy USB receiver. The system broadcasts music and RDS messages and proves the approach works.
