Produce short single channel pulse. #208

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Latest FW on latest taranis.

There appears to be no simple way to produce a short (single) channel pulse on 
switch selection and another pulse when the switch is returned.
I need a video start/stop switch which pulses once for on and again for off.
I have a workaround ANDing 2 out of sync timers (due max 175 sec) but its not 
working great. Also using the momentary switch is possible but if you hold it 
for more than 1 sec it will turn on/off.

I can see no way to 'do something' only if switch MOVES from a to b but not 
when AT a or b.

apologies if im missing something oblivious.

What your asking for is a sequencer feature.  OpenTX for Taranis already 
provides this feature.

This is not a place for getting programming help, but since mixer menu provides 
speed parameters on individual mixer lines, for your output channel you would 
only need two mixer lines (one for the starting point, & one for the end 
point).  The easiest way to visually get from point A to B is using a Custom 
Curve, but that approach is not necessary.

Thanks. That hint about 2 mixers with delay has allowed me get it working.
As far as programming help is concerned, I did not post here lightly. I have 
read all the available information (including the 1200 page 'how to' forum)and 
have asked for help on a number of RC forums all of which drew a blank. Even 
with your help, a search for 'sequencer feature' produces nothing either.
I thank you for your help so please advise where is the appropriate place to 
get help if all usual places fail.

The best place for questions would be on openrcforums.com. 
The issue tracker is really for bug reports and concrete new function 
suggestions.
