EdgeTx auto reset altitude on motor arm.
Posted: 26 Jun 2025, 09:40
I have several gliders with vario/altimeter and hence the desire to zero the altitude before flight. This needs the Reset>Telemetry instruction - but if driven directly by the arming switch gets implemented continually. So it needs a short logic set/high on arming. This is done by Sticky Logical Switch:
L0& Sticky !SG^ - - 0.1s
Sticky means it goes on when a condition is set (not disarmed) but goes off by some other condition - that can be another switch/event or can be duration - set here to 0.1s. Reason for 'not disarmed' rather than armed (SG-) is that I use the third position for vario. The reset is then by Special Function:
SF$ LO& Reset Telemetry Enable
Can also be used for other initialisation needs e.g. reset timer x
Works on TX16s.
