 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. The transmitter uses the Raspberry Pi's PWM generator to produce VHF signals.
