I was wondering if anyone had any idea's on how too intergrate a DTMF decorder with a microcontroller.
The application i am using this for is, too have a PIC MCU control a secured enterance on an apartment building and i want the PIC too call through existing phones too each suite. Once the call is received, the tentant can hit the # key too let the user in. I have all the other ends of this project underway, just the intergration of the DTMF circuit is giving me some trouble.
Anyway help would be great.
