    No I haven't tried it, but according to Mr E's multicalc, a PWM PR2 value of 64 yields @8Mhz gives 259 steps, with a value of 258 yielding a duty of 99.23%

    Unless I'm missing something obvious (highly likely!), I'd have thought it'd be simpler to set a HPWM PR2 number that gives exactly 256 steps (therefore a max duty value of 255)
