I anyone has some code to produce DTMF tones.....thats about as simple as you can get thats well documented i'd appreciate it. David Thomas's code is real good and he has been helping me but all the extra keypad stuff seems to be confusing me. I just want a program that lets me put in the values of the tones I want. I anyone has this in the Parallax instruction set i'd appreciate it. I'm going to use this as a memory tone dialer, just a few phone numbers programmed into it, so I don't need anything fancy. If it was written for a clock speed besides a colorburst crystal....i'd appreciate some info on doing the math. I don't know too much about PICs either, I had been programming the 68HC811 for a while and it seems like I have to learn about the PIC's again. Thanks deicide@fia.net
