Ask teachers, how to realize the STM32 F103 series of ADC precision adjustment? F429 can choose resolution directly, but can't F103, so whether can modify read 12 variables to achieve? But ADC_DR register is read only register, how to modify variables? Beginner STM32, if, can provide routine will be better, thank you

CodePudding user response:

You take out a few not directly reduce the accuracy of the yao
If too much will reduce the sampling frequency fluctuations

CodePudding user response:

Sampling period set longer, AD clock is reduced, to improve the accuracy of the AD

CodePudding user response:

This is considered, are processed by other AD chip directly! Look, there is a good way to share!
