The LED Matrix library allows you to easily interact with an 8x8 LED Matrix using .NET

Feature highlights:

• Write Bitmaps to display
• Write byte arrays to display
• Clear display
• Set rows
• Set Columns

And more helpful features

To use the LedMatrix you first grab the dll file above, and put it into your project. For more information on how to set up a dll file, refer here.

You also have to set up the LedControl library. How?

Grab the zip file from that repo, then in the Arduino IDE, navigate to:

Sketch > Include Library > Add .ZIP Library. Then select "Add .ZIP Library".

Find the .ZIP file, select it, paste the "ledcontrol.ino" file into the IDE, and you're good to upload.

For more information on .ZIP libraries, refer here.

LedMatrix lm = new LedMatrix("COM8", 9600);
// --stuff--

LedMatrix lm = new LedMatrix("COM8", 9600);
byte[] data = {
  0b10101010,
  0b01010101,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000
};
lm.Write(data);
stuff

Takes an array of bytes and writes the bytes to the ledmatrix display.

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.Write(new byte[] {
  0b10101010,
  0b01010101,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000,
  0b00000000
});

Takes a filepath to a bitmap as well as the pixelwidth, converts to a byte array, then writes the data to the ledmatrix display.

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.Write("C:\dev\my_img.png", 1);

Sets all leds on the display to off

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.ClearScreen();

Takes a row and a byte to write to the row, each bit corresponding to an LED

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.SetRow(5, 0b00101010);

Takes a row and a byte to write to the column, each bit corresponding to an LED

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.SetColumn(5, 0b00101010);

Takes the path to the .gif, the length of time before the next frame, and the pixel size.

LedMatrix lm = new LedMatrix("COM8", 9600);
lm.WriteAnimation("C:\dev\my_gif.gif", 1000, 1);
