## Features
|
|
|
|
|
|
|
|
|
|
- Networked display reciever compatible with Groovy-based protocols for low-latency graphics.
|
|
|
|
|
- Supports 5 "strings" of HUB75 panels, enabling 320x256 maximum display resolution when using 128x64 panels.
|
|
|
|
|
- Supports complex display transforms, such as rotation.

## Building your Groovylight
|
|
|
|
|
|
|
|
|
|
The hardware involved in making a groovylight is simple: It uses the Colorlight 5A-75B Receiver board as the driver and supports various HUB75
|
|
|
|
|
displays. When thinking about displays, consider target size, display resolution, and panel layout. Due to RAM limitations,
|
|
|
|
|
it required that the total number of pixels per-row does not exceed 256. This means that if you use a 128x64 panel, you can have
|
|
|
|
|
up to 2 of them in series. If you're using a 64x64 panel (not recommended for most setups), you can have 4.
|
|
|
|
|
A total of 5 strings of HUB75 panels are supported, *but they must be the same size*.
|
|
|
|
|
|
|
|
|
|
You can see the setup of a 240p-size display below. It uses 10 128x64 P2.5 panels. One string (2 panels) is rotated on the edge
|
|
|
|
|
to get 320 pixels, and there are 8 extra pixels on the top and bottom.
|
|
|
|
|
|
|
|
|
|
## Simulator
|
|
|
|
|
|
|
|
|
|
A Verilator-based simulator is used for behavioral testing but can also be used to experiment with display layouts.
|
|
|
|
|
The sources can be found in `sim/`.
