liudr:
Sorry for lingering here beyond the [Solved] word but I thought this library provides a way to manipulate timer1 for PWM (arbitrary period and 10bit):
That library looks nice. I must admit that the question was asked in terms of register manipulation, and that's how I answered. Plus I like to understand what all those registers do.
edit: duh, I should reduce the frequency, shouldn't I?
Not sure I understand that question, but 10 bit PWM sounds pretty precise. And you are right, if you write a 1 there is a long gap before the next 1. I suppose it depends on what you need.
