Implementation of power ON/Off feature:

[pavan]

hello all, I am using nRF52832 and blow is my querry.

1. Implementation of power ON/Off feature:We are able to put the board to system ON low power and System OFF low power modes. However, we want the system to wake up on button press+hold of 5 sec. For this, as per our understanding, since we need to have a timer to count seconds of button press+hold, the system should be in System ON low power mode. When we do this, the system keeps restarting/resetting. ?

2. SAADC issue: We are trying to implement battery monitoring mechanism using SAADC example. We are facing issue with reading the value in buffer. The buffer keeps reading some unwanted junk values though the pin is connected to fixed input voltage (voltage devider).?

Pavan,

It's tough to know why the unit is resetting and your ADC isn't working. Can you provide some example code?

If your device restarts, it most likely ended up in the error handler due to an error code. The default recovery method when an error occurs is to reset the device. Please have a look at this post about debugging to check which function returns the error, and what the error code is.

As Darren said, please provide code examples showing how you setup and sample SAADC, and what values you are seeing. There are examples in the SDK and on this GitHub page, showing how to use the SAADC peripheral.
