For example: If you want to chain two of these horizontally to make a 128x32 panel you can do so by connecting the panels in series using the HUB75 ribbon cable. Than you must provide proper configuration structure to the class constructor letting it know that you use "one long virtual matrix chain". Refer to [Pattern Plasma](/examples/2_PatternPlasma/) example for all the details about configuration setup.
Finally, if you wanted to chain 4 x (64x32px) panels to make 128x64px display (essentially a 2x2 grid of 64x32 LED Matrix modules), a little more magic will be required. Refer to the [Chained Panels](examples/ChainedPanels/) example.
Finally, if you wanted to chain 4 x (64x32px) panels to make 128x64px display (essentially a 2x2 grid of 64x32 LED Matrix modules), a little more magic will be required. Refer to the [VirtualMatrixPanel](examples/VirtualMatrixPanel/) example and the [AuroraDemo](examples/AuroraDemo/) example of its practical use.
Resolutions beyond 128x64 are more likely to result in crashes due to [memory](/doc/i2s_memcalc.md) constraints etc. You are on your own after this point - PLEASE do not raise issues about this, the library can't magically defeat the SRAM memory constraints of the ESP32.

## Animated GIF Decoding Example
### Prerequisites
1. The excellent 'AnimatedGIF' library by Larry Bank needs to be installed: https://github.com/bitbank2/AnimatedGIF
2. The files in the 'data' folder are written to the ESP32's SPIFFS file system. In order to be able to do this using the Arduino 2.0 IDE, you need to install the ESP32 LittleFS plugin: https://github.com/lorol/arduino-esp32littlefs-plugin
Follow the instructions in the link to install the plugin: https://randomnerdtutorials.com/arduino-ide-2-install-esp32-littlefs/

Description:
* This demonstrates a combination of the following libraries two:
- "ESP32-HUB75-MatrixPanel-DMA" to send pixel data to the physical panels in combination with its
in-built "VirtualMatrix" class which used to create a virtual display of chained panels, so the
graphical effects of the Aurora demonstration can be shown on a 'bigger' grid of physical panels
acting as one big display.
- "GFX_Lite" to provide a simple graphics library for drawing on the virtual display.
GFX_Lite is a fork of AdaFruitGFX and FastLED library combined together, with a focus on simplicity and ease of use.

A port of Aurora visualisations
======
Not all of the visualisations have been ported. About 17 of 37 work, or have been included as I think they look best.
