A Particle library to convert color values between red green blue (RGB) and hue saturation value (HSV).

Usage

Add the hsv library to your project and follow this simple example:

#include "hsv.h"

HsvColor hsv(hue, 255, 255);
RgbColor rgb = HsvToRgb(hsv);

Flash a full example that animates the RGB LED in a rainbow pattern.

Documentation

RgbColor

Structure with red, green, blue colors.

// Create black
RgbColor rgb;
// Create with color
RgbColor rgb(255, 255, 0);
// Extract colors
RGB.color(rgb.r, rgb.g, rgb.b);

HsvColor

Structure with hue, saturation, value colors.

// Create black
HsvColor hsv;
// Create with color
HsvColor hsv(255, 255, 0);
// Extract colors
unsigned char hue = hsv.h;
unsigned char saturation = hsv.s;
unsigned char value = hsv.v;

HsvToRgb, RgbToHsv

Convert between the 2 color types.

HsvColor hsv = RgbToHsv(rgb);
RgbColor rgb = HsvToRgb(hsv);

Contributing

Here's how you can make changes to this library and eventually contribute those changes back.

To get started, clone the library from GitHub to your local machine.

Change the name of the library in library.properties to something different. You can add your name at then end.

Modify the sources in and with the new behavior.

To compile an example, use particle compile examples/rainbow command in Particle CLI or use our Desktop IDE.

After your changes are done you can upload them with particle library upload or Upload command in the IDE. This will create a private (only visible by you) library that you can use in other projects. Do particle library add hsv_myname to add the library to a project on your machine or add the hsv_myname library to a project on the Web IDE or Desktop IDE.

At this point, you can create a GitHub pull request with your changes to the original library.

If you wish to make your library public, use particle library publish or Publish command.
