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?
