Dtmf to Si570?
- Has anyone developed any software/hardware to do Dtmf to Si570?
what I had in mind was to remote a Softrock with Skype and be able to
control it with a cell phone.

I have made DTMF/cellphone interfaces about ten years for hundreds of
application like a remote control of the ham equipments, for a pay
eagle camera, a remote water alarm,a remote reset,a remote temperature
controls, a remote windgenerator alarms,a remote car heaters etc.
Basically remote control works adding control numbers to end of the
phone number or just pushing the code buttons when the connection is
Adding an I2C interface is only a small detail if somebody finds it
Skype needs a PC and a connection from audio to the DTFM input.
I suggsest an UDP-server instead of Skype.
The UDP server gets commands through a local I2C hadrware using serial
communication to SI570.
