Fuori frequency measure

[Vlelectroniclab]

Hi everyone,
I have to do a project where I have to read 4 frequencies at the same time.
the frequency ranges from 0 to 500hz.
I wanted to use esp32s3.
anyone have experience? you can help me?
regards Vito

Sounds doable. What research did you do yourself already?

There are 4 independent PCNT units on an esp32-s3. There is not an arduino wrapper for pcnt, but the IDF functions will work if you just include the appropriate headers.

Hi, thanks for the replies. does anyone have any files for example that are not complex? I'm seeing the best frequency meter, but it's very complicated for me now. Greetings
