calculate pwm resolution

[mrdevis]

Hi,
and thanks for the work you have done on this!
I have a small question as I am a little stuck here.
If I program a PWM frequency of say 100Hz, how would I be able to calculate the resolution of the pulse width?
cheers

The resolution is not determined and is not fixed value as this is hybrid ISR-based, not purely hardware-based PWM.
It depends on many factors such as settings, how many PWM channels you're using, ESP8266 speed, etc.

But the resolution can be guessed around ms, and can be OK with slow PWM, which is the purpose of this library.

It's easier for you to measure the resolution, if necessary for some purpose, by writing extra code to measure. Treat this as an exercise for you.

Good Luck,

Ok, thanks for your reply. So it was hard to figure that out for a reason then :) I will approach this differently then.
