How to configure an additional pwm output?

PX4 Autopilot Configuration & Flight Modes ⚙️

hi All,

is there any way to configure an additional pwm output for wingwing?

i almost have the feeling that i have to adjust this file and compile it again.

Is there an easier way to configure additional PWM outputs?

thanks,

Alex.

I think that’s correct. May I ask what the additional PWM outputs are for?

i’d like to turn “on/off” the fpv gear like cam, osd and video tx by using RC and turn it off after a crash.

In the docs i found a possibility to edit the mixer file without compiling.

I copied wingwing.main.mix and to /fs/microsd/etc/mixers, added the follwing lines and rebooted.

M: 1
S: 3 5 0 20000 -10000 -10000 10000

3 in second mix line stands for Manual Passthrough.
5 in the same line stands for aux1. i mapped an rc channel to aux1 by using qgc

Not sure this is right.

Pwm out 5 has no pwm signal.

i’m wondering if i need an additional mixer as described here

is there some logging about loading the mixer file?

okay found a bit hacky solution. my working mixer file locks now like this:

M: 2
S: 0 0 -6000 -6000 0 -10000 10000
S: 0 1 6500 6500 0 -10000 10000
M: 2
S: 0 0 -6000 -6000 0 -10000 10000
S: 0 1 -6500 -6500 0 -10000 10000
# this will be aux
M: 1
S: 3 5 10000 10000 0 -10000 10000
#throttle 
M: 1
S: 0 3 0 20000 -10000 -10000 10000

i don’t know why, but pwm1 - pwm4 is active. pwm5 and pwm6 not. since pwm3 is not used by wing wing, i chose this as the output.

why is pwm5 and pwm6 not active? How do I activate it?

I still haven’t found out how to configure an additional servo output. Isn’t that possible somehow?
