Hi i am getting issues running a PMOD AD1 on a Zybo Z7 -20 programmed using latest version of 2021.1 Vitis and Vivado. I am using the example code from https://github.com/Digilent/vivado-library/tree/master/ip/Pmods/PmodAD1_v1_0/drivers/PmodAD1_v1_0/examples However the issue is that the ad1 shows 0-4095 for 0-1.65v and then another set of 0-4095 for 1.65-3.3v, effectively splitting the reference voltage of 3.3v into 2 1.65v portions for ADC conversion. Not really sure how to solve this issue. My block diagram in vivado is the default settings
