Switching multiple auxiliary functions with one RC channel?

ArduCopter Copter 4.1
1

Hello,

I would like to switch multiple auxiliary functions with one switch: 31 (Motor emergency stop) and 94 (VTX PIT mode) - at the same time.

Unfortunately, I didn’t find any option except transmitting that switch on a different channel a 2nd time.

Is that possible somehow, e.g. via a lua script? There I found get_pwm(), but no way to trigger functions.

Thanks
Sebastian

@Sebb,

We haven’t yet merged the feature to allow Lua scripts to execute auxiliary switch options so this isn’t possible for now. It may be that we get this included in Copter-4.1.0 but I can’t promise that.

Depending on your transmitter, you could make the switch operation affect two channels.

Yes, that’s what I meant with “except transmitting that switch on a different channel a 2nd time”. I did that in the past, but I only have 16 channels and I’m using 15 already…

Sorry, no option for doing that. One channel, one auxillary option.

Yes, you can do that on master. Merge was quite recent.

@peterbarker, are you sure it’s been merged? I think this is the PR that needs merging to allow Lua scripts to trigger auxiliary switch functions.

Hello,

I just looked into that, one minor question (before even having tried it yet):

I understand it can only set low/high/toggle (?) as parameter? If I could set a pulsewidth as input, it could also e.g. set the transmit power for Smart Audio, based on e.g. RSSI level in future…(?)

@Sebb,

That might be possible. The trouble I see though is that scripts can’t currently directly read the pwm input. Script can’ read a “button’s” state (e.g. on or off) and a button can be setup to switch on or off based on the pwm value… but scripts can’t read the underlying pwm value going into the “button”.
