Default iX20 mAh used callouts

Is it possible to have the iX20 read out battery percentages at pre-determined intervals?

For example, warnings at 75%, 50%, 30% and 20% of rated battery capacity?

If that's not possible, can you have it read out pre-determined intervals of mAh used/remaining?

I've gotten as far as configuring a switch throw to tell me mAh on demand, but I'd rather have it work as an automatic fuel gauge so I can finally get rid of the flight timer...

Are you using a smart esc and smart batteries? If not then you will need the Spektrum energy sensor.

You can program the DX-, NX- & iX to call out out the value of any sensor based on time - EG: Speak the value of "mA Consumed" every X-seconds.
And, of course, you can program an alarm based on when sensor reaches a value that you entered - EG: 3500 or 5000.

You would have to write a macro that compares a fixed value ("Total Capacity") against a measured value ("mA Consumed") and calculate the percentage ("Total Capacity" / "mA Consumed" x 100) and then only speak if the value is one of 10 values (0%, 10%, 20% - etc, etc, etc).

If you could write that macro and it could run at least once per second, it might work.
