If I change the ADC settings, do I need to ADC calibrate again?

[rs__zen]

Hi.

I'm using the MKE14F MCU.

In ref manual, it written It is mandatory to calibrate the ADC after power up or reset.

So, after calibrating once, for example, if I change the conversion mode from 8-bit to 12-bit, do I need to calibrate again?

Or is such a change in settings irrelevant to calibration?

Please tell me.

Thank you.

Hi rhata,

You don't need to calibrate again after change the conversion mode from 8-bit to 12-bit.

AN5314 ADC Calibration on Kinetis E+Microcontrollers may help you better understand.

Best Regards,
Robin
