Tone frequency limits.


I'm currently trying the tone() function to drive a stepper motor. But the function seems to not work under 31Hz. Did someone ever calculate the frequency working range of the function ?


I think it is in the documentation.

Yup, it is.


I always use to understand the functions so I didn't see the documentation. I'm French and I'm not so familiar with English. Reading these docs can be tricky for me.

Thank you.

OK, I concede, it is a bit of a paper-trail

takes you here:

and then here:

Where it says that with a clock speed of 8MHz, the minimum frequency is 31Hz with an eight bit timer.
