Greetings,

Just wondering if anyone has been able  to modify SimpleUSB or USBradio channel drivers to be able to use GPIO pins on the PI 3 for PTT and COS.

This would be very useful for using potted sound fobs where you can not access the COS and PTT pins.                

I have noticed that the VK Link guys have channel drivers that support this feature.

Check out their Chan_SimpleUSB,  Chan_USBradio configurations.

Looks like the work has been done, wondering if this could be added to official DIAL release features.

Sure would be nice for folks that want to experiment without having to spend very much to play in the Allstarlink technology.
