Hi Zitron,
I understand the Futaba PPM signal on the module pin is open collector.
So, using your PCB, I added "digitalWrite(3, HIGH)" to the code and it now works -- sort of...!
The spec-an software shows a nice signal.
The servo I had attached to the Rx is jittering something awful and was crashing the gear against the end stop, so I stopped testing pretty quick.
I'm using your RF22 code from here:
On my ghetto 3v3 version, I loaded the same Tx code and the Rx gives a short flicker on the red LED as if it receives something then stops, also no signal appears on the spec-an software.
Will there need to be any code change to make a 3v3 Pro Mini work ?
I have this board, which has the addition pinouts
On your board, which way does the switch/jumper give low/high power?
Jumper across 3v3 and GPIO2 gives high power??
Sounds good reference your new PCB's.
We're getting there!!
Nigel.
