Battery beep was created by domcars0

PB as you are here .. Have you an idea of how often firmware enter the main.c::BATTERY_Check() ? I'm playing with code to have multiple bip when TX battery is low.

It is called every 100msec in the LOW_PRIORITY section.
The other call only executes on powerdown.

Also, Please create new topics for new ideas. I don't really like having threads polluted with unrelated topics. It makes search very hard.

take a look at the timer code. that beeps every several seconds after going negative. it'll give you an idea how to make the battery beep continue.

I've made code modification in the main.c file...
Now Battery alarm is beeping every 5 secunds.

It works on my Devo10 and in the devo8 emulator.

I would just remove the use of 'warned' for bit 0x02 altogether, you don't need it.
I'd probably also use CLOCK_getms() instead of a counter, so it is more obvious exactly how frequently to warn.

Hi PB,
I kept the warned 0x02 bit in case of hysteresis issue ( in the worst case we can have a beep every 200ms

) , but for sure you can remove it ...
We can also use the CLOCK_getms() but I tought that use of a counter variable is much less power hungry (no function call) and beep interval is not critical at all.
