FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. FastLED is used by thousands of developers, in countless art and hobby projects, and in numerous commercial products. We build FastLED to help you get started faster, develop your code faster, and make your code run faster. FastLED supports popular LEDs including Neopixel, WS2801, WS2811, WS2812B, LPD8806, TM1809, and more. ...

An Arduino NeoPixel support library supports a large variety of individually addressable LEDs. Please refer to the Wiki for more details. Please use the gitter channel to ask questions as the GitHub Issues feature is used for bug tracking. A library to control one wire protocol RGB and RGBW LEDs like APA106, SK6812, WS2811, WS2812, and WS2813 that are commonly referred to as NeoPixels and two-wire protocol RGB like Lpd8806, APA102, and SK9822 commonly referred to as DotStars. Supports most...

...Note, some effects make use of more than one color (up to three) and are programmed by specifying an array of colors. Random color introduced alternating from start and end of strip. Alternating white/red/black pixels running. Strobe effect with different strobe count and pause, controlled by speed setting. Classic Strobe effect. Cycling through the rainbow.

...Use for STEM, Coderdojo or similar coding events. Recursive REPEAT statements. INSTANT ON / OFF = Turns on / off immediate execution of commands FD x = Forward x pixels BK x = Backward x pixels RT x = Right by x degrees LT x = Left by x degrees PU = Pen Up (Do not draw) PD = Pen Down (Draw) REPEAT x = Creates a loop to run x times which runs any commands within the loop. Place END or ] when closing loop. END or ] = Closes a REPEAT loop. (can be nested) PEN x = Color of pen (0 - 9) SETBG x = Color of background (0 - 9) CS - Clear screen CT - Center Turtle (Return to Home position) RUN = Runs the current list of commands shown on screen DELETE / DEL = Clears the command list RESET = Clears commands and resets your Turtle SAVE filename = Saves a png of the working graphic to your documents folder QUIT

A Test button is free software that helps display the appearance of button status. * It has different options for customizing button appearances * It is used for shows from the button (two to five) statuses as limited ( normal, click, disabled hover, selected) * it has a fully virtual test status of a button * it has a full option of controlling the appearance of the status button * The source code is included in the setup file for (MSVC) and has been tested with a fully working...

PerceptualDiff is an image comparison utility that compares two images using a perceptual metric. That is, it uses a computational model of the human visual system to determine if two images are visually different, so minor changes in pixels are ignored.

Pixel Toaster is a portable open source framebuffer library for C++. It provides a fast and easy way to get your pixels on the screen. Floating point and truecolor pixel formats are supported on Windows, Mac and Unix.

is a collection of ultra-simple routines I've found useful for making small interactive graphics applications. === Functions include === * Window creation * 32-bit RGBA bitmap creation * Fast software based drawing routines (pixels, lines, text etc) * Mouse and keyboard input === Details === * Written in C * Python bindings provided * Permissive BSD licence * Win32 version currently. Linux and Mac planned. === Performance === Running on Windows XP on an Intel Core i3 530 (3.4 GHz): * Putpixel - 31 million per second * Rectangle fill - 11 billion pixels per second * Text render - 11 million characters per second (8 point, fixed width font)
