I am trying to use the GPIO pins on the Odroid U3 expansion I/O board to control the repeater logic signals (COR/PTT) but all I could find was information on using either the GPIO pins on the cm108 fob (which must be modified to use) or using a parallel port. The Odroid U3 doesn't have a parallel port and I think the native GPIO pins should have the capacity to use the COR/PTT signals.</span><div style="font-size:12.8000001907349px;"><br clear="none"></div><div style="font-size:12.8000001907349px;">I can't find any information on how to go about using the native GPIO pins on an sbc for All Star Link.
