as I was not really satisfied with the software PWM implementation from the SDK, I rolled my own.

A lengthy blogpost with details:

The actual code:

I am going to use this, if only because it has the source available! I hate these binary blobs!

Now only either someone makes an espconn interface to the open LWIP implemention or I modify my source to talk directly to LWIP and I am happy

- Wed Jul 20, 2016 6:13 am #51089 BTW is it completely interrupt robust? What happens when I (very) frequently change the PWM values (which some of my code does), is it interrupt safe (request in that code to change of the PWM duty happens in normal context, not interrupt).
