My servo seems to have suddenly changed it's PWM frequency. This is the second time it's happened with completely different hardware. The first time I was a complete novice and thought I'd done something wrong.
Now I'm still pretty new but my servo steps used to drive a wheel about 300 degrees... today it suddenly drives the same wheel about 450 degrees. I have no explanation except I think the PWM frequency must have changed somehow. I don't set it in my code... Is that possible?
I have no other explanation how the movement can have change so significantly.
