As the AD convertion begins by software,the converted data is stored in the ADC_IDTRx register,where the x is 0 to 2.COM will print these values. Notice: Because there is an offset,when inner temperature sensor is used to detect accurate temperature,an external temperature sensor part should be used to calibrate the offset error.
