ESP8266 - Slider Max PWM Value 12 bit unsupported, with data mapping

I use ESP8266 with Arduino IDE, which defines by default max GPIO PWM value as 1023 (12 bit).
However, into Blynk project max PWM values are set to 255, inpependently of board type.
This limits upper PWM value for 25% of duty cycle in the data mapping mode!!!
In fairness it is not a problem for direct pin value access mode, because extreme values can be reset.

@vshymanskyy could you please advise?

Well, the proposal is:

  • set max PWM value for 1023, when board ESP8266 selected,
  • or customize it with a parameter: resolution - (8, 9 or 12 bit).
