When I using S32K, give the AD input pin 1.6V voltage, use 12bit precision, in my understanding, It should be approximately 2048, however the ad value get is 0. When I using the same AD code reprograming other board, the value read is true. So I'd like to know where is wrong?
(Notes: the ref voltage I used is internal value which should be VDDA and VSS)
Thanks a lot!
