I'm getting into discus launched gliders and I've acquired a Frsky variometer for use in reporting my height and vertical airspeed. The telemetry works great--I have the current values displayed perfectly.
My puzzle is trying to figure out how to get er9x to record the highest altitude value observed until cleared. I've read the manual and it seems that the 'Latch' logical switch mode is the right choice. I noticed that the custom telemetry display will show global variables... and I can assign a global variable to accept the values of a pair of logical switches. Seems like I"m nearly there, but the GV field in the custom display screen remains 0. I suspect I don't quite understand how latch switches look.
Here's the logical switch pair that i hacked together...
The thought is that the latch logical switch will be triggered any time altitude is greater than 600 feet. I live at 900 feet, so it should always be on.
Logical switch 2 is a latch that sets its point when L1 is triggered, and clears when the throttle momentary switch is flicked (which right when I launch it). None of this happens, of course. How close am I?
Code: Select all
LSw Funct V1 V2 L1 v>val Alt 600(feet) L2 Latch L1 THR
