AdvancedAnalogWrite | enabling PWM features on certain pins

AdvancedAnalogWrite is a C++ library. AdvancedAnalogWrite has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

advancedanalogwrite is a library for enabling pwm features on certain pins beyond what the standard arduino ide offers. 1.0.1 eliminated requirement for backup registers affecting millis()/micros()/delay() functions. 1.1.0 added variable resolution modes for 16 bit counters and ocr top for 8 bit counters and phase correct pwm on 16 bit counters; requirement for bitdepth field for write() is eliminated and pwm mode specifier for write() can be 0 for speed to skip checks on pwm value for speed. 1.2.0 added initialization with a pwm frequency option. 1.3.0 added query functions and demo sketch is now universal. supported boards (and derivatives): uno (mega/leonardo/atmega8 will be included in a later release). fast pwm (maximum 1/256 cpu frequency vs 1/32768 for most pins vs 1/16384 for certain pins) and phase correct pwm. on certain sets of pins, pwm resolution (can be faster than 1/256 cpu frequency). programmable pwm frequency prescaler with external t input for external clocking of supported pins. ability to stop and resume micros()/millis()/delay() to avoid conflict with these functions. readback of current pwm value. usage: init(pin, bitdepth, mode, polarity): initialize pwm on a certain pin and if set for external clocking, set the external clock input pin as an input and enable its
