Is the Vref output always available when the processor boots up, or is it only good during an actual A/D conversion. I am not getting any output on my Vref pin, and I want to know if it is a hardware problem with my module, or if it is a software issue.
I have tried to measure the Vref output on the BufIn and the Bufout of the A/D chip on th core board, but there too I only get a few millivolts of output instead of the expected 2.5V
