These functions take an 16-bit unsigned integer (uint16_t) and return a signed 16-bit integer (int16_t). Another possibility is to split your leds into multiple shorter strips of leds, which would allow you to have even shorter periods of time with interrupts disabled (and/or not having to worry as much about frame writing being interrupted by long interrupts if you have them enabled) this how good it is for the microcontroller to be calling show successively through FastLed. You can use a technique (supported by FastLED) called "temporal dithering" that can improve color fades, but doesn't really help with brightness fades at low light levels (like fade-in/out). 7 on Windows 10 (installed a while ago to upload a premade program on a Duemilanove) central include file for FastLED, defines the CFastLED class/object This community is for users of the FastLED library.
