Hi All,

I'ld like to count the frequency (or number of pulse) for the application shown in the image attached;

However, I would like to use Minimum hardware interaction as the MUC (STM32L4) will be busy with other tasks.

Could you please suggest the best approach possible?

 

Best regards,
CM

you can use input capture to count the rising edges.
