CC3D Atom and PPM input not working

[acidg]

I have flashed version 2.6.1 to my CC3D Atom and am using a FrSky DR4-II in PPM mode. However, the input is not recognized.
I used pin 3 and 6 of the receiver port as well as pin 6 of the servo port.

The board is working with port 3 of the receiver port and Cleanflight 1.10.0

If you are counting the original PPM pin as 3 (it's actually 1, VCC and GND don't count), then you need to use pin 8, not 6. Last pin of the receiver port.

Sorry, I meant pin 1 and 6. I tried both of the pins, but the signal is not recognized.

Last pin of the receiver port, pin 8, worked for me. This matches the convention from openpilot firmware, but not cleanflight firmware (or docs) which specify pin 3.

Pin 6 (the last one) doesn't work for me. @renejsanchez are you also using a D4R-II receiver from FrSky in RX_PPM mode?

I have also problems with CC3D ATOM,D4R-II and PPM on Pin 8 with oneshot and without oneshot, it doesnt work. Betaflight 2.3.4 is working fine with PPM on Pin 3, but releases after that are not working.

On Librepilot with Flexi Port PPM and Receiver Port Disabled+Oneshot it works, but i would like to fly with betaflight.

That pin has been moved due to timer issues and loss control on PPM.

Please read release notes after 2.3.4

Now i have tested all pins from the Receiver Port, only Pin 3 works with version 2.3.4. I think there was a problem on Pin 8 of my CC3D Atom black pcb. My second CC3D Atom, also black pcb does not work too, only Pin 3 and PPM works. With my normal CC3D (black pcb) i have no issues with PPM + oneshot and Pin 8.

Cool. I will close this issue to prevent cluttering

I'm using an orangerx r410x in rx_ppm mode.

https://github.com/renejsanchez are you also using a D4R-II receiver
