Hi all,

I'm trying to acquire the value of many ADC inputs on my FRDM-KL25Z. Actually, I saw the example Measuring all ADC inputs on FRDM-KL25 using DMA and i'm trying to do this. But, I don't understand very well the ADC Offset Correction Register.

In this example, that register is set to 4U. I just don't understand why. Can someone explain that?

Thank you!

Hi,Oliverira

This register is used to correct ADC calibration. For example, you calibration our ADC module by a external standard power supply. Then you can transfer data to register ADCx_OFS after you compare testing result and expected result.

Best Regards

Paul
