UHF digital wireless microphone based on the arduino DUE and cheap SI446x modules with 26mhz oscillator.
The project is using DIY shields; 2 x Audio CODEC (WM8731) Mikroe 506 Proto Boards 3 x SI446x shields ( 1 on TX shield and 2 on true diversity RX shield )
The project includes a true diversity reciever setup and will hopfuly support embeded LTC timcode TX RX.
This Code depends on;
Radio modules driver , RadioHead RH_rf24 http://www.airspayce.com/mikem/arduino/RadioHead/classRH__RF24.html
Custom 200khz RF mask GFSK connfig file fir 26mhz oscilator based modules made with free WDS software had problems with this so went back to using;
I2S SSC driver for ARduino Due
ArduinoDueHIFI , https://github.com/delsauce/ArduinoDueHiFi
LTC Timcode decoding / encoding, libLTC, https://github.com/x42/libltc
IMA_ADPCM audio compression library , http://yxit.co.uk/source/documentation/classIMA__ADPCM.html
It early days, don't expect this code to work at all !!
