I just went through this same process - literally yesterday. It was very frustrating until I ran across this video, which explains everything in detail.
Hope this helps,

Re: Measuring the battery with a blue pill
Remember too that the complete circuit also includes the input impedance (resistance and capacitance) of the analog input pin. With 1M resistors, the analog input impedance might be significant. You are probably better off with something like 100K resistors, which are pretty much guaranteed to be ...
