* allow to set pin to OUTPUT_OPEN_DRAIN in analogWrite
* remove parameter with default value
* Update core_esp8266_wiring_pwm.cpp
* update documentation accordingly
Matching standard Arduino cores, make the default analogWrite() take
values from 0...255. Users can always use the analogWriteRange() call
to change to a different setup.
Add a `analogWriteResolution` which takes a number of bits and sets
the range from 0...(1<<bits)-1, part of the standard Arduino API.
Remove the PWMRANGE define. It's non-standard and not generally valid
(i.e. it's fixed at 1024 of 256, but the real range varies depending on
what you last set).
Also add note about the change and how to fix pre 3.0 applications.
Fixes#2895
* Add info about installing python3 on Mac, Linux
The Mac requires special handholding to allow SSL connections for
get.py, so document those for end users.
* Add interrupt section to docs
Adds a section on interrupts to the docs and lists the restrictions
and warnings about running long tasks.
Fixes#6428
* Update per review comments
* Analog input voltage can be 3.3V
According to this tutorial and my personal test with my Amica, 1.0V delivers 320 and 3.3V delivers 1024 at 10-bit resolution. I guess 3.3V is possible.
