Hi everyone,
I'm very new to STM32 Discovery and I want to do some project with it. I need to capture PCM signal(voice) from GTM382 modem before it reaches CODEC. I know there is PINS:
PCMSYNC  - 8 kHz
PCMI - PCM input, which is devided into 8 byte slots.
So I need to overtake it, I need to make STM32 Discovery clock work simultanously with GTM382 modems' (2MHz) and PCMSYNC will show me when is begining of new slot of 8 bytes(flag), so I need to take the stream correctly and send it to PC (make a .wav file). Please help. Any suggestions?
