Hi  

The datasheet show the 12-bit ADC frequency is 20Mhz.

When I setting the processor expert of the ADC, it always show "Warning : A/D frequency is too fast" and "Warning : A/D frequency 1 is too fast"

No matter how you change the frequency, this warning will not disappear.

Did I miss anything that I didn’t set?

 

 

Thanks,

Kris

Hi, Kris,

I have tested to try to input different value for the "Clock divisor select value" box, the "warning: A/D frequency is too fast" always appears, so I think it is a bug of the PE for MC56F84xxx for CodeWarrior for mcu ver11.x.

Pls do not care about it.
