The attached code drives the CM8880 DTMF chip and was lifted from the parallax site http://www.parallax.com/Portals/0/Downloads/docs/cols/nv/vol1/col/nv7.pdf and ‘tweaked’ to work with a 28x2 (I hope adequately.. please advise if not!).
I have left all the original comments in so as to keep context.
I have not tried the code live; but my question concerns the simulator.
Please tell me why on the simulator the pin A.4 pin ‘button’ flashes on when symbol CS_p referenced (only evident when debug/pause as inserted by Froggs).
Otherwise I think the code will do what I want!
Thanks for your comments in advance.
