Hi,
I've been loading the example ADC program that come with MQX 3.8.1 on to my m52259demo board. It's working on screen (via serial). However, I'm having a tough time actually sampling anything. I don't know how it was set up. Primarily, I understand that your ref voltage pins are based on what you write to the CAL (power reference) register. I have tried connecting AN2 to the board's 3.3v output and AN6 to the board's ground and to the supply's negative terminal. I then connect AN0 to the supply's positive terminal. Is this the correct way of setting it up. There's no changes when I vary the DC power supply's voltage.
On the other hand, I can't even touch the Vrl and Vhl pins. They come straight off the microprocessor.
Can anyone with experience with the ADC program that comes with this MQX help? Cheers
