Arduino library for calculating PWM DCs for a linear LED brightness ramp.
CIE1931 is a small C++ library (if you can call it that!) that uses constexpr to generate a lookup table for translating a PWM duty cycle scale into a mostly linear brightness output.
Maintainer: Chris Marc Dailey (nitz)
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
