LED easings for Raspberry Pi Pico by using PWM and easing functions. Implementing some functions described at easings.net.
See pico_led_easings.h for available easing functions.
See main.c for usage example demo.
For quick demo just drop pico_led_easings.uf2 into your regular Pico (non W).
Optionally, if you have an RGB LED (common cathode), wire it up to pins 16, 17, 18, and GND. In fact, a regular LED works too with any of said pins.
