RTOS/CC2650: Read ADC value from an Analog capable pin

Part Number: CC2650

Tool/software: TI-RTOS

Hi Team,

I am using CC2650 in external regulator mode. I have changed my Board as per the suggestion and used voltage divider and connected to PIN (IOID_7).

Now I am changing board files to use ADC and measure voltage I have checked related post but Idea is not clear how to use ADC can you explain in detail.

Also I have seen in one of the post which says currently RTOS updated only to use light sensor and not updated ADC to measure voltage in external regulated mode.

If its updated can u guide me how to configure and use it.

I am working on 2.2 Stack.

Thanks and Regards,

Hello,

IOID_7 is not a analog capable pin. You will need to change this to one of the analog capable pin, these are:

IOID23
IOID24
IOID25
IOID26
IOID27
IOID28
IOID29
IOID30

Also our ADC drivers will read out raw data and we provide a ADCBuf_adjustRawValues and ADCBuf_convertAdjustedToMicroVolts API that will convert this raw data into uV.

Hi AB,

Okay,So Battery level measurement using voltage divider for external regulator is possible ?

Thanks and Regards,

Hello,

Do you mind sending that piece of the schematic and I can review it for you.
