Calculate RPM base on number of motor poles

[Rimbaldo]

Hi! Can you add a getRPM() version for Brushless Sensorless BackEMF motors, based on the frenquency and number of motor poles?
Like a get_brushless_RPM() ?

For instance, for my motor it would be: (frequency in hertz) * 2 / (number of motor poles) * 60

Or could you add this function here and then I'll add to the tachometer.h?

Thanks!

Hi, you can use getHz() and add your math around it
