you might try Google 'dtmf decoder PIC' ther are 1,000s of hits. First one is a complete project, quite detailed, and up to you to convert to CCS C or just use as inline asm....

Dear n-squared,

I have used your sent code. The program is running well but I have a little mistake. The FVR voltage is not stable. If I put on the voltage the measured FVR is less. If I put down t ...

Dear n-squared,

Thank you for your code. My PIC 18F25K20 perhaps is not good, because the measured voltage is zero. I have to order some new pieces. But my PIC18f45K25 is going with your program co ...
