We are using this device with an external reference of vref- = 0V and vref+ = 2.5V
If I set the HIGHEXTREF bit of adc1con I am only getting half my range.
If I do not set this bit I am able to use the full range. However I am not getting the readings I expect.
What is the proper configuration for this register using these voltages
These are my other settings for adc1con
adc1conDefaults = BIT15 + BIT11 + BIT4
