Hi Kurt,
I’m looking at the ReadReceiver example, but so far the TimerOne lib is not compiling. A good example of using the pin change interrupts, as you said.
Could be a candidate, if the compile errors can be resolved.
I know why he flips back and forth between rising/falling edges, maybe he needed to do that for the particular XCVR he choose? What was the “overlap” you mentioned, and on which XCVR(s)? I’m thinking of getting the Futaba 7C.
