It would be possible to add the library to the DTMF ?

Hi David,

Deal with RC models and I would like to take control of their mobile phone or GSM module and DTMF. The principle is simple DTMF tone has 16 with the receiver it is possible to remotely communicate with the 4-bit communication. The range of the radio is using GSM network and virtually unlimited communication is possible on both sides.

Looking for this project a compiler that can both DTMF synthesis and recognition, DTMF tones.

It would be possible to create for Firewing library to handle DTMF tones for both synthesis and detection of incoming tones?

Some compilers can generate DTMF, but they can not recognize the incoming. Firewing would be the first that should the library had!!

You could possibly use Pwm to generate the DTMF - I found this link on the web

which seemed quite useful. I've not had any experience doing this myself so cannot offer much advice. As for detection, again not any experience, but this Microchip application note may help

Hi david,

Rather, I had a request to add DTMF functions from PROTON IDE or AMICUS to Firewing at least a little bit to extend this feature.

Thank you
