Can't get SAR ADC to work on CY8Ckit-049-42xx
For some reason, I cannot get the ADC to work on this project (attached). I am using miniprog3 for debugging and have a varying DC signal on the input pin to an op-amp. The op-amp output is internally wired to one input of the SAR ADC. Program compiles ok, except I get a warning that one of my variables "result" is declared but not used. I don't understand that- code is below. Anyway when debugging, with 0 V input or 5 V input the "result" is 0x05DB (or something like that) and changes a little from read to read, but does not reflect input voltage at all.
What stupid thing am I doing wrong?
result = ADC1_GetResult16(0);
