用8051MCU做了个RDS发生器,产生RDS CLOCK和RDS DATA,只是没有做FM调制发射出去, 但这个东东对于软件开发已经足够. 作出来的产品经过测试没发现有问题. 简易RDS信号发生器的51程序. RDS CLOCK ==> P1.7 RDS DATA ==> P1.6 具备PS, RT, CT功能. 其中CT特地做成每秒钟发送一次,发送分钟和秒信号,用以检验解码的稳定性. 设计时以11.0592MHz为准. 但12MHz应该也OK的,

The prologic extract compressed 4 channel in stereo mode. You can get center channel by adding Lt + Rt. And surround channel also can be recovered.
