SAADC with timer to start ADC conversion every 1 hour

[Avi]

I see many questions on how to enable a timer to start SAADC conversion every period (such as 1 hour).

But never found a simple example.

I would appreciate if you can modify this example: https://github.com/NordicPlayground/nRF52-ADC-examples/blob/master/ble_app_uart__saadc_timer_driven__scan_mode/main.c

to support a timer of 1 hour and keep SAADC inactive to save battery

Thanks

Hello,

Please try take a look at the example I posted here: https://devzone.nordicsemi.com/f/nordic-q-a/71940/low-power-mode-using-saadc-with-ble_app_beacon/296061#296061. I used an app timer instance to trigger periodic sampling of the VDD input voltage.

Best regards,

Vidar
