led-animator | Web UI to drive one or more RGB LED Matrix Panels

led-animator is a JavaScript library. led-animator has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

If you are using a standard LED panel, its recommended to use the RGBMatrix Hat along with it. It makes hardware setup easier and there are some nice NodeJS APIs for talking directly with the board. No Python or Arduino required. It is highly recommended that you disable the sound on the Pi to prevent flicker on the LED Panel. You will need to jumper pins 4 and 18 on the board as well. This makes a big difference and is worth the extra bit of work. If you are using a 64x64 or 64x128 panel you will also need to add solder to pad 8 on the board to enable the proper LED addressing. You will also need some additional command line options to define the shape of your panel. See the bigPanel.json config file for an example 128x64 setup. You must run NodeJS with sudo so that it gets the proper hardware access needed for high refresh rates. example: sudo npm start config=panel1. Nothing special is needed to play animations on the Creator LEDs. In the Web UI, it will appear as a panel with the size of 35x1. There is an example config file for the creator in the /config folder. The SenseHat comes with a 8x8 LED display on its face. Like the creator, nothing extra is needed to drive the LEDs other then using the proper configuration. There is an example in /config.
