I am learning Air Manager and LUA as I’m going along, so it’s a bit of a steep learning curve. I’ve got a bit stuck on the Clock/Chrono/Elapsed time display in the centre panel of the Toliss A321 I’m coding.
I would like to have the chrono to only display when Volts >= 10, and to disappear when I press the RST button. The clock needs to be on display all the time. I’m having a lot of trouble getting this to work, even though I have watched Tony’s YouTube tutorials and watched a 3-hour crash course on LUA! I seem to either have it on all the time, or it stays invisible, or the timer doesn’t run.
With the current code, it’s just staying on all the time.
Once that is sorted, I will want to start to code the Elapsed time Chrono.
Could someone take a look and show me the error of my ways, please?
Thanks in advance!
