ADC Driver
On the STM32 is a 12-bit analog-to-digital converter (ADC). The role of an ADC is to take an analog signal as an input and give as output a digital number proportional to the magnitude of the input signal. The following formula can be used to determine the ADC reading:
...
In addition, the ADC has two different modes for converting analog signals:
- Single Conversion Mode: The ADC performs the conversion for a channel and stops after the conversion for that channel has been completed
- Continuous Conversion Mode: The ADC will convert a channel indefinitely at regular intervals
