BATTERY LEVEL MEASUREMENT ON CUSTOM BOARD

[SAISUSMITH PALADUGU]

Hi Nordic,

For battery_level measurement on the SDK we are using a timer such that for every 5 seconds or 10 seconds if the timer expires then the saadc will be triggered for sampling the voltage which we then pass it to percentage level conversion function of SDK to know a particular level of the battery.

Is there any interrupt support in the SDK for doing battery_level measurement instead of the using the timer such that as soon as the voltage drops from the battery to our required level an interrupt will be triggered and that corresponding interrupt handler gets executed???

Could you please guide through an example or related example if there is an availability  for interrupt support on the SDK for battery_level measurement??

IDE: Segger Embedded Studio

Board: Custom Board based on nRF52832

SDK:14.2

Softdevice:S132 , Version - 5.0.0

Computer Platform:Windows10

Thanks and Best Regards,

Susmith

In addition to what has already been said by awneil you can also use the Power-fail comparator, provided you have the battery connected directly to the nRF (and not via an external regulator).

Thanks awneil and Einar for your reply.

I will go through the datasheet and the design and get back to you.
