hi,
I see in the datasheet that there is only a formula for the frequency calculation of the pwm (fcounter/(4096 - atr).
Is there a formula for the duty cycle calculation ? thanks to all

Hi Spectre,
if you need a formula, in Wikipedia you'll find the term duty cycle : ....the term duty cycle is used to describe the fraction of time that a system is in an "active" state.
So the formula you'll get for the duty cycle must be (DCR-ATR)/(4096-ATR) or (4096-DCR)/(4096-ATR) according to the polarity you chose. Right?
Regards,
WoRo
