Tone frequency limits.

Hello,

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 ?

Phoenix-74.

I think it is in the documentation.

Yup, it is.

Sorry...

I always use http://arduino.cc/en/Reference/ 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

http://arduino.cc/en/Reference/Libraries

takes you here:

http://code.google.com/p/arduino-tone/

and then here:

http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation

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