RPI-RGB-LED-Matrix

Setup

Hardware

• Make sure you have pins 4 and 18 on the Adafruit LED Matrix Hat soldered together. Otherwise, the LED refresh has a lot of blinking.
• In Pi3 ModelB: If you have the sound module snd_bcm2835 loaded, unload it using sudo rmmod snd_bcm2835. That module and the LED library are not compatible.
• If you have more questions, please also refer to hzeller/rpi-rgb-led-matrix.

Software

• Add the rpi-rgb-led-matrix library from Github as a folder in the root directory of this project.
• Add a games folder with games in the root directory of this project.
  touch games/test1
touch games/test2

Compile and Run

• Compile the project using make in the root directory of this project.
• Run the ./build/gameSystem file, which starts the controllers and menu by running: sudo ./build/gameSystem --led-gpio-mapping=adafruit-hat-pwm.

Others

gamepad functions integrated

To Run the gamepad_example.c

gcc gamepad_example.c ./gamepadHandler.c ./gamepadEventHandler.c -o gamepad_example -I../headers/ -lpthread -lrt

run hzeller’s LED sample on Pi

• Disable sounds
  sudo rmmod snd_bcm2835

If this doesn’t work, please try:
sudo vim boot/config.txt

Change from dtparam=audio=on to dtparam=audio=off.

• run demo on adafruit 32*32 led matrix
  sudo ./demo --led-gpio-mapping=adafruit-hat -D 1 runtext.ppm

• Image Viewer in ‘Utilities’
  To compile, you need install the GraphicsMagick dependencies first:

sudo apt-get update
sudo apt-get install libgraphicsmagick++-dev libwebp-dev -y
make led-image-viewer

Then, you can run it with any common image format, including animated gifs:

sudo ./led-image-viewer --led-gpio-mapping=adafruit-hat some-image.jpg       # Display an image.
sudo ./led-image-viewer --led-gpio-mapping=adafruit-hat animated.gif         # Show an animated gif
sudo ./led-image-viewer --led-gpio-mapping=adafruit-hat -t5 animated.gif     # Show an animated gif for 5 seconds
sudo ./led-image-viewer --led-gpio-mapping=adafruit-hat -l2 animated.gif     # Show an animated gif for 2 loops
sudo ./led-image-viewer --led-gpio-mapping=adafruit-hat -D16 animated.gif    # Play animated gif, use 16ms frame delay
