According to the description provided in the official manual of ST, it is not difficult to see that the ADC analog watchdog is actually that the user can set an upper and lower limit of the AD value...[Details]
The analog watchdog of the ADC is used to check if the voltage is out of bounds. It has two upper and lower bounds, which can be set in the registers ADC_HTR and ADC_LTR respectively. The library fun...[Details]
The STM8L contains a 12-bit ADC with 25 input channels, including an internal temperature sensor, an internal reference voltage As can be seen from the figure above, there is an internal re...[Details]
How to convert the pin voltage value into V using the built-in ADC of STM32? V(ADC) = Value(ADC) * V(ref)/4096 (The ADC of STM32 is 12 bits, so the maximum value of the AD word is 4096)
Where V(ADC...[Details]
