Hello

I am about to make my own library of ADC hardware. But first, I'll try to use ADC Analog Watchdog for my project. But there is a problem I think I cannot face it. I want to use only 2 channels with analog watchdog. The others, I want to use as single convertion or scan mode. Reading the datasheet, I found a description as follows:

Can I use only two channels with watchdog and the others normally (scan mode) ? Thanks for all answers.

Hello

Sousa.Flavio

,

If I understand well, there are several channels programmed in the ADC sequencer, and only 2 of them must be monitored by the analog watchdog.

In fact, for STM32F1, it is not possible to monito

r only 2 channels. I

t is either one channel or all channels.

This is detailed in the RM0008, in the

Table Analog watchdog channel selection.

O

n some others series like STM32F3, STM32L4, ... you can do that.

You can use STM32CubeMx which help you in your ADC configuration.
