[arm-allstar] Receive PL control with simpleusb

[James K4JK]

Cole,

You may have figured this out already but I was going through the archives
and thought I'd chime in.

I think you're trying to accomplish what I've done with the repeater I'm
building... I have a comm spec TS-64WDS that is connected to the
discriminator of my receiver.

The TS-64 has a Mic Hang up feature that is designed to control whether the
RX Mute Output pin goes into Channel monitoring mode. In the default
configuration when the input pin for this feature (Pin 2, violet) is
grounded the tone decode function on the tone board behaves normally. If
you float or apply a voltage to this pin, the Channel Monitoring feature
will turn on and the RX Mute output will behave as if the board is decoding
CTCSS.

I use RX Mute Output #2 (Pin 7, Brown) for CTCSS input to the URI (Pin 7.)
It grounds when the board is decoding CTCSS so I have ctcssfrom=usbinvert
in my simplusb.conf.

Also in simpleusb.conf I have gpio2=out0, which initializes the GPIO pin
and is hooked to pin 2 of the ctcss board.

I have a couple of commands in my rpt.conf that control this GPIO pin:

60=cop,62,GPIO2=0 ; Turn off GPIO 2
61=cop,62,GPIO2=1 ; Turn on GPIO 2

So *60 will enable CTCSS decode, *61 will put the repeater into
carrier-only mode.

Eventually I will try to setup voice confirmation of the tone decode going
on and off.
