Hello,My adc clock is 140.625 KHzMy sample time is 239.5 CyclesSo my Conversion time = 239.5 Cycles + 12.5 Cycles = 251.5 Cycles.1 Cycle = 1/Adc Clock 1/140.625 KHz = 7.1uSSo total conversion time = 251.5 * 7.1uS = 1.78msi.e my sampling frequency = ...

Hello,My objective is:Read voltage in 10 channels of Blue pill using Scan and Poll conversion mode.Problem I face is:Wrong values are read. When I feed 3.3v to the adc input (any input), its adjascent channel reads 3.3v, but that too changes to 2v. ...
