internal reference voltage varies a bit from chip to chip. Try to use thecalibration driver, that should compensate for the reference voltage and partly for the nonlinearity, but you may be better off also changing the resistor divider so the value is more in the middle of the ADC range. ...

To get the maximum ADC performance (2.4 MSPS, at 2.4V to 3.6V supply range), the ADC clock must be set to 36MHz. As ADC clock is equal to APB2/2, then APB2 value will be 72MHz which lead to maximum AHB (System clock) at 144MHz. Since the sampling time is set to 3 cy...

To recognize fever, the temperature of the body, depending on the location of measuring, ranges from 37.2 to as much as 39 degrees Celsius (°C), most sources take 38 °C as the average limit value. Given the diverse range of publications, pediatricians have problems with giving the ...
