On demand ADC application [ADC of STM32]
This program displays the data acquired by manually starting AD conversion of the 1-channel analog input signal of the STM32 ADC each time it is needed.
Numerical data of analog voltage taken from PA0 is converted to character strings for display and sent serially to a PC for monitoring.
In this circuit, the output impedance should be a little larger, depending on the resistance of the volume.
Serial communication for monitors is the simplest, pointer-style string transmission without interrupts.
