[arm-allstar] Remote Base BCD Channel Steering

[Doug Crompton]

Ed,

In researching I saw you asked the same question years ago and I did not see an answer then. Did you ever get one?

Using the GPIO on the Pi to BCD control a radio would not be hard. In fact a user has already done that using function codes and an external script I wrote to control the bits. It is in use commercially.  

The idea for the future code we are writing is to get specific stuff out of the base code and put it where users can create their own interfaces to whatever hardware they want.

Here are the basics of how I would do it....

Use the patch command (with a different code) to pass DTMF to a Linux script via an extensions.conf dial plan.
Then the script would take the number sent, convert it to BCD or any other format the radio requires
and send it to the GPIO bits. Of course you would have to interface those bits to the actual hardware.
If you needed to pass a code to a remote node you would use the standard codes to pass the command to the remote nodes dial plan.
