MatrixDemos

A collection of demos for a Raspberry Pi and the Adafruit 32x32 matrix

Software Dependencies

• Python >= 3.6

• Pillow

• pygame (for joystick support)

Hardware Dependencies

• Raspberry Pi 2, 3, or 4
• Adafruit RGB Matrix HAT
• Adafruit 32x32 RGB LED Matrix
• 5V 4A power supply
• USB joystick (optional)

Instructions

1. Assemble your Matrix HAT
2. Wire up and configure the Raspberry Pi
3. Install MatrixDemos

sudo pip3 install MatrixDemos

Now, the MatrixDemos are installed. You can test by running this, which lists the possible demo commands:

python3 -m matrixdemos

Usage

Execute any of the following console commands.

• matrix_digitalclock: Shows the time and date. Run with -sdn to only display time.
• matrix_analogclock: Displays a simple analog clock, use command line options to change colors
• matrix_slideshow path/to/images/: Display images from a directory. Use -l to change the slide time in seconds, and -b for the background color
• matrix_snakegame The classic "snake game" now on your matrix! Requires a USB joystick!
• matrix_stars Displays some twinkling stars. Use -s to adjust speed
• matrix_textswarm Displays text flying about. Use -c to edit the text color, and -b for the background color.
• matrix_animations [[PATH]/[DEMO]] Shows an animation from images in a directory. Use -f to adjust framerate, and -l and -n to control looping. Use -g to specify an animated gif or video
• matrix_scrolling [[TEXT]/[PATH]] Scrolls text or an image from left to right. Use -c and -f to adjust text color and font, -s for speed, -r to repeat, and -b to bounce.

Visit the Gallery to see a visualization of each demo.

Setting Colors:

When setting the color on (ie. -c in matrix_textswarm) you can specify either the color's name (RED) or its hex code ("#ff000").

Example of setting the color of the analog clock: matrix_analogclock -c "#333" -s Red -m white -h "#aaaaaa" -b "#001"
