I'm building this project a part of which will entail sending DTMF tone over an RFS radio to a recieving radio.
Transmitting the DTMF tone is done by a PIC16F628, which I happen to be programming with the PICBasic Pro Compiler (Yes I know basic is bad :wink: And No, I did not shell out $250 for the compiler). Fortunately DTMF out is a standard function in the PICbasic compilers so I have no problem there.
The trouble comes in when I want to recieve the DTMF tones over the second radio with another PIC16F628. I don't know how I could recieve the code using the PIC directly. So I thought that maybe I could use an external IC. Unfortunately the only one I can find is from Parallax.com and they overcharge for everything (I much prefer mouser.com or Jameco.com). So I wonder if any of you know were I can get one? I've scoured google without a single hit. (But I keep hearing people talk about them.)
If you don't know of a place I could find a DTMF decoder, but know of a better way to recieve the DTMF tones, or a better way of sending data over a radio please tell me.
