That's great, I'm glad you have now got it all sussed out.

but now realise the period is critical when choosing duty

Yes, that it why I showed the period as part of the duty calculations.
If the period is change then the Duty value must be updated to give the same %.

Thanks for the help and giving me the insight to playing with the pwm function

You're welcome
