- Add 100us settling delay after enabling voltage divider - Average 8 ADC samples to reduce noise - Disable voltage divider after reading to save power (~2uA) - Move ADC configuration to begin() for consistency - Move getBattMilliVolts implementation to .cpp file Signed-off-by: Reid Tonking <Reid.Tonking@gmail.com>
- Add boot voltage protection (won't boot below 3.3V) - Add LPCOMP wake configuration for voltage recovery - Implement initiateShutdown() with LPCOMP wake on low voltage - Enable NRF52_POWER_MANAGEMENT build flag Device will enter protective shutdown on low battery and wake automatically when voltage recovers to ~3.7V or USB is connected.
