Hi there,
I'm using a PIC 16F877 with PIC Basic and a MT8870D chip and I need to get the PIC to receive and process the incoming signals from the DTMF decoder IC. Does anyone out there have some sample code I could use for this?
Many Thanks!
Maria.

Might this help? Its assembler, but explains the MT8870D very nicely.

Or take a walk on the wild side and use the CM8880:

Oh oh. Melanie is going to get you. Look what I found in the archive:

hi there,
i've had a look at the links you (Don) sent and they are a little too complex for what i need to do and what i can understand with my very limited basic knowledge of PICs, PIC Basic & DTMF signalling - does anyone out there have a very simple PIC Basic program to receicve the signals from an MT8870D and display them on a simple 7 segment LED display?
thank you! :)
best wishes,
maria.
