I am using an external battery management. I need to get a pin high within 500ms. I am running my code with
SYSTEM_MODE(MANUAL) but that doesn’t really help. I made the following timing measurements:
- I connect 10v to VIN.
- 790ms: the 3.3V pin starts outputting 3.3v. I think this is due the BQ24195 (Is there a way to disable it?).
- 1,5 sec: The first line of code is executed. (Maybe the bootloader?)
Anybody an idea how to meet the time limit?
