Title: Setting up DX8 xm to use rotating knob as TX PID input
Post by: weepop on November 25, 2015, 09:16:54 pm

Hi
my first post and I am a noobie to quads.
I have nearly finished my Robocat 270 (two flty esc's delaying completion) and I am trying to get prepared for adjusting pid's on the fly. I want to use the knob on my xm (labled aux3).
On xm I have altered in switch select to be aux1,  and in gcs  config/input tab have allowed channel 6 as PWM and to accessory 0.

When I do transmitter setup wizard I get no response on accessory 0 when I turn the knob!!

What am I missing ????

Hi,

Are you using the PWM so all wires (one wire per channel input) connected to Receiver ?

Be sure you setup your radio as needed, put a servo on receiver output to test or monitor output in your radio.

Redo transmitter wizard

Yes to above and xm monitor shows aux1 responding to knob !!

If there is receiver output change and something connected on it (input wire), transmitter wizard should detect automatically when it ask you to move the accessory0.

It does not detect any input.

I have tested receiver with servos and all channels work including CH5  as three position flight mode and CH6 as variable controlled by knob.
I have also checked continuity of the wire for CH 6 connection into cc3d.

I must be missing something in setups of the cc3d.

when you follow Tx wizard the last channel (Aux/accessory0) is not detected ?

throttle, Pitch/Roll/Yaw/flightmode are ok ?

Please post your config file:
File > export Uav settings

Thanks f5soh I have located my problem to be a bent pin on the cc3d receiver input socket resulting in no channel 6 input.
All works OK now.
