Hi Dan.

Generally following equation is applies:

You must know scale of frequency. Scale * Q.15.

For example scale = 1000 Hz, if Q1.15 = 0.4, then frequency is 1000*0.4 = 400 Hz

I hope this helps.
Best Regards,

Hi Dan,

It would be helpful if you could provide us more information, which MCU are you using? Are you running a demo project?

Thanks in advance!
