I'm getting the following error when I try to compile. Using the latest version on Arduino 1.8.5.

Mmm... It should be loading the pwm.h file under libs folder...

I'm getting this to, what is the prefered lib to use?

[xoseperez]

ESPurna uses ESP8266_new_pwm (https://github.com/StefanBruens/ESP8266_new_pwm) by Stefan Bruens. It's basically a drop-in replacement for the SDK pwm.cpp library, it is copied in the libs folder along the header file where the methods are defined.

I can see these file do exist under the lib folder but i'm still geting errors:

i'm only asking as the strip lights i'm trying to use must have the Red and Blue Swapped over. I'm using magic home RGBW

[xoseperez]

The Arduino IDE is a pain in the a**. It will work by moving the pwm.c file from "espurna/libs/pwm.c" to "espurna/pwm.c".

With that change, it successfully compiles.
