Power consumption 52832

[Jason Anderssen]

Hi,

I am relatively new to programming hardware at this level, and have developed our product on the 52832, so finally I have purchased the Power Profiler Kit, and downloaded the NRFConnect and power profiler software.

Please see the attached screen shot, and can I ask if this is a good result in power consumption, or should I be trying to improve it further?

Sorry for such a newbie question, and any extra information or links to information to learn about power consumption more, would be fantastic, and much appreciated.

Cheers and thanks in advance for your help

Hi Einar,

One more question, if you dont mind answering, your help has be invaluable!!!  In the example's I have seen for SAADC, how iimportant is the calibration, should I be implementing this in our product? How accurate is the battery reading if I dont calibrate vs do ?

Cheers and thanks again

Jason

Hi Jason,

We have not specified the accuracy of the SAADC without calibration. Why would you not want to do it? You can use the internal reference (so no HW requirement) and the SAADC driver support it, so it should only require a minimum amount of work on your part. It should not have any practical impact on average current consumption either, provided you don't do it often. I suggest you at least calibrate once at startup. After that you do not necessarily have to calibrate it again unless there are large temperature variations (see this thread).
