Battery Voltage sampling

Post by puijkh »

Hi is the battery voltage sampled bu the STM32 or by the ESP32.
I would like to sample very fast to log the voltage waveform of a start the sd-card.

What is the number of bits for the sampled voltage, would it be possible to see the voltage ripple from the alternator in the sampled voltage?

Thanks in advance, Hans.

There is no fixed sampling rate for battery. It is measured on request.
