I implemented two 12 bit ADCs on the CY8C29466, each with its own PGA. Even though the PGAs are tied to different ports at different voltages I get the same reading from the 2nd ADC as I do from the first. The first ADC reading is correct. Any thoughts? I was planning to use one ADC and MUX between the channels but I couldn't find any code examples for switching the MUX. Thanks in advance for any help.
