Title
A/D conversion results may contain erroneous data due to possible variances in the internal power supply voltage during
Take an average of more than one conversion result.
conversion. This is caused by the flash memory and A/D converter sharing the same power supply in the MCU.
Perform A/D conversion on the analog input to the same pin four times sequentially. Discard the maximum and minimum
values from the A/D conversion results and take the average of the two remaining values.
