===DTMF Tone Decoders=== | |||
I recently became aware that at some point, CD&F made DTMF decoders that use the two tone decoder PCB and have a Norcomm NC401 module attached to them. The manual for the module can be [[:File:Norcommnc401.pdf|viewed here.]] Its based on an 8051 mcu and the classic MT8870 DTMF decoder IC. You can program various functionality and digit sequences into it. | |||
