Hello,
I'd like to build a pulse to tone converter so that my father can run his old telephones on his current phone like. Unfortunately I'm not even sure where to start. Has anyone built one of these before, or could point me in the right direction on how to create the specific tones the phone line is looking for? I have some basic uC programming skills so if I knew what I needed to look for from the pulses, and what I need to output for the tones, it would be a great start.
Thanks.
