Bug? NodeMcu ESP8266 AnalogWrite values

[derez]

Testing the NodeMcu I have found that the max value in AnalogWrite is 1023 (= digitalwrite(true)), not 255.

It sounds like a bug in ESP8266 libraries as Arduino analogWrite command expects values between 0 to 255.

On ESP the default PWM range is 0 to 1023.
And default PWM frequency is 1KHz.
http://esp8266.github.io/Arduino/versions/2.0.0/doc/reference.html

These values can be changed.
Attached is the files.

Copy rESP8266.xml to folder: C:\Program Files (x86)\Anywhere Software\B4R\Libraries
Copy rESP8266.h and rESP8266.cpp to: C:\Program Files (x86)\Anywhere Software\B4R\Libraries\rESP8266
Remember to create a backup copy first !

I hope the right person will include this in the next version of B4R

I have agreed with starChild and the functions will be included in his Esp8266Extra library !
