Nano-3x3-LED-Cube

Code for a simple 3x3 LED Cube using the Arduino Nano.

You can find the schematic for the cube here.

Adding animations

To add animations, you'll need to add code in main.cpp, animations.h, and animations.cpp in the src/ directory.

LEDCubeBase functions

As LEDCubeXZOutYIn inherits from LEDCubeBase, all these functions are available to you. Check out lib/LEDCubeBase.h for the class definition. (I'll probably forget to update this list, so you really should check out the header)

void setPixel(ledCubeAxesLength_t x, ledCubeAxesLength_t y,
              ledCubeAxesLength_t z, ledCubePixelValue_t value);
ledCubePixelValue_t getPixel(ledCubeAxesLength_t x, ledCubeAxesLength_t y,
                              ledCubeAxesLength_t z);

void fillYZPlane(ledCubeAxesLength_t x, ledCubePixelValue_t value);
void fillXZPlane(ledCubeAxesLength_t y, ledCubePixelValue_t value);
void fillXYPlane(ledCubeAxesLength_t z, ledCubePixelValue_t value);
void fillCube(ledCubePixelValue_t value);

virtual void update() = 0;

void updateFor(uint32_t duration);

Changing wiring

The architecture of the LEDCube library makes it pretty easy to change how the frame buffer is actually displayed. You'll need to create a new child class of LEDCubeBase and modify the update function to actually display what's in the frame buffer. Check out LEDCubeXZOutYIn to see how I did it.
