Lloyd,
I thought that I had sent you the attached text files before.?
You basically need to define what GPIO you want and what it's initial state should be in SimpleUSB.conf. (at the bottom in my
example file)
You then map DTMF functions to cop commands in rpt.conf. These DTMF commands will then allow you to "bit-bang" the GPIO as
needed. Once you have that working, I think Doug has a set of macros that will allow you to "write" all of the necessary bits
with one command.
I found this post. It uses the Rpi pins, but I'm sure it could be modified to use the CM119 GPIO instead:
