## FM-RDS transmitter using the Raspberry Pi's PWM ## FM-RDS transmitter using the Raspberry Pi
This program generates an FM modulation, with RDS (Radio Data System) data generated in real time. This program generates an FM modulation, with RDS (Radio Data System) data generated in real time.
It is based on the FM transmitter created by [Oliver Mattos and Oskar Weigl](http://www.icrobotics.co.uk/wiki/index.php/Turning_the_Raspberry_Pi_Into_an_FM_Transmitter), and later adapted to using DMA by [Richard Hirst](https://github.com/richardghirst). Christophe Jacquet adapted it and added the RDS transmitter.
