Sticky throttle hold, take 2

last time this was raised in the wrong place, and the answer was "it needs virtual channels". Now that we have them - I still can't figure it out. For those not familiar with it, the idea is that throttle hold doesn't go off when throttle hold switch is turned off, but stays on until the throttle is at zero. This means that turning off throttle hold won't suddenly spin the props I'd the throttle isn't at zero.

Part of the problem is lack of examples for using virtual channels. This might make a good one.

I don't think that has as much to do with virtual channels as conditional switches. For example

if THR !< -99 VIR1 = -100 (or something to that effect.)

Until we have that kind of logic included then what you are looking for is rather hard, if not impossible to do.

This kind of thing is really powerful and why I love er9x so much.

I'm sure it will work it's way into Deviation in time.

That's about what I'd decided in my attempts to do this - I couldn't figure out how to get that THR < -99 value from anything. Depending on how powerful the conditional switch system is, a virtual channel might also be needed. The OpenTx implementation of the sticky throttle needs (or needed when I found it) them.

This leads to another thought of mine: embedding a scripting language into deviationTx for such things. The processor has enough power to do this, but you probably don't want to run a compiler/interpreter on the transmitter.

Your real wish (throttle hold waits until throtte low)will be hard to realize because the mixer system has no possibility to store values somewhere. It always reacts on actual values of inputs.

A interpreter will probably run on the mcu, but the code size and the gui for this might exceed its capabilities (besides the effort to implement).

This is what OpenTx uses a virtual channel for. One of it's inputs is itself.
