OpenTx Tricks: Voltage callouts and logical switches

A request over on my discord someone was asking how to get their radio to tell them what the battery voltage was. Here is a quick and dirty video on how to do that.

If you add an "AND switch" at the end of his string of commands on the Lxx logical switch, and add in your armed switch, it will only become true when you're armed and flying instead of when you're plugged into your computer. That can get annoying quick..lol Thanks for the video brother.. Been at this for 6 years and didn't really care to know this stuff until it snowed me in and I got bored and wanted to learn something new.. lol Appreciate you guys that takes the time to make these videos!

Great advice on the logic switch.

[@MCsCreations]

Fantastic tip, Dan! Thanks a lot! 😊 Stay safe there with your family! 🖖😊

[@gammagonad1657]

Awesome and very useful function, that most pilots don’t know how to program. As always thanks Tweet!

Hey really glad you made this video because I have done this in the past and it's on my radial master now. I have a switch that will read out my RSSI and a switch position that will read out my average cell voltage. But if the battery ejects or becomes disconnected it's simply keeps reading out what I think is the last known reading. So if my radio is saying 3.7 volts, 3.7 volts, 3.7 volts and then crashes and a disconnect the battery it just keeps saying 3.7 volts. Or if my RSSI is speaking out 89 DB, 89 DB, 89 DB and I crash and eject the battery, I flipped the switch and it will keep saying 89 DB. Shouldn't it be going to 0 DB because there is no more signal or 0 volts because there is no more battery? Any help is appreciated thank you

My t12 pro only lists vbec.Not vfas.

[@TweetFPV]

It's going to be different based on your receiver

@@TweetFPV I use spektrum and vbec is giving me radio voltage not aircraft.
