Yeah, I would not load that pin; just throw an unity gain amplifier at it and you should be good.
Ok that makes sense to me. It felt a bit hack to put a load on it
If the value I measure at this pin without a load does not match the value burned into the efuse that sets vref is there a way to override that value so that I can give it a more accurate readings? I am seeing the estimates generated by
Code: Select all
Return values that are always about 10mv too high and I am wondering if this is due to the fact that the efuse is not the same as that which I read from routing adc2 to gpio.
