Colorduino GFX Library for Arduino

This library depends on a slightly modified version of the Adafruit GFX library and provides advanced drawing functions(lines, circles, text, ...) for the Colorduino or the Colors Shield.

Installation

The Colorduino GFX library depends on the Adafruit GFX library. Use the original Adafruit GFX library or the 8-bit mode of the slightly modified version for a smaller code size. Download and install the dependencies first.

Download the source code and rename the uncompressed folder to Colorduino_GFX. The folder should at least contain the files Colorduino_GFX.cpp and Colorduino_GFX.h. Place the folder in your <Arduino-Sketch-Folder>/libraries/ folder and restart the Arduino IDE.

Usage

Include all required libraries first.

#include <Adafruit_GFX.h>
#include <Colorduino_GFX.h>

Create a new Colorduino instance.

ColorduinoPanel Colorduino;

Initialize the Colorduino and set the white-balance in the setup() function.

void setup() {
  Colorduino.init();
  Colorduino.setWhiteBalance(36, 63, 63);
}

Now the Colorduino is ready to use.

void loop() {
    GFX_Color_t color = Colorduino.color(255, 0, 0);
    Colorduino.drawLine(0, 0, 7, 7, color);
    Colorduino.swapBuffers(true);
}
