MSPM0G3507: Changing ADC resolution on the fly

Philip Neaves

Part Number: MSPM0G3507

Tool/software:

Hello.

Changing ADC resolution on the fly but not sure it's working:

DL_ADC12_initSingleSample(ADC12_0_INST,

DL_ADC12_REPEAT_MODE_ENABLED, DL_ADC12_SAMPLING_SOURCE_AUTO, DL_ADC12_TRIG_SRC_EVENT,

DL_ADC12_SAMP_CONV_RES_8_BIT, DL_ADC12_SAMP_CONV_DATA_FORMAT_UNSIGNED);

Is the above enough, or does other magic need to be done to change the resolution ?

Thanks

Phil

I think you need to make sure that CTL0:ENC=0 by wrapping your call with

> DL_ADC12_disableConversions(ADC12_0_INST);

[...]

> DL_ADC12_enableConversions(ADC12_0_INST);

Setting ENC=0 then =1 should be benign if the ADC isn't actively converting.

Yes, please follow Bruce;s recommendation, and have a try.
