Jim,
I hope you and your family are well.
I am setting up an old quadcopter that requires a PPM input to the flight controller. I flew the thing about five years using a Nano Rx configured to output PPM on pin 2. At that time I used a Futaba 9C transmitter with your XPS Futaba 9C Tx module.
Now I want to fly it with an OpenTx transmitter. I have your JR type Tx module in the Jumper T12 and I use it frequently to fly models equipped with XPS receivers - no problems.
However, I am unable to make the Nano output PPM using the Jumper T12 and XPS JR Tx module.
My gut feeling says that the transmitter and XPS JR Tx module should not care how the Nano outputs the servo signal, whether it be PWM or PPM. It worked when set for PWM and I was able to drive a servo directly. But when I re-binded it and changed the output from PWM to PPM (led "solid on"), I could not get an output.
Can you think of anything I am not taking into consideration?
Thanks,
Paul
