DisplayServer

DisplayServer is a TCP server accepting commands to control a LED matrix display connected to the Raspberry Pi.

Building

To build DisplayServer, the LED Matrix library has to be installed in $HOME/libs/rpi-rgb-led-matrix. It can be cloned and built from https://github.com/hzeller/rpi-rgb-led-matrix.

Server

Build the files. Then run either DisplayServerLed or DisplayServerMock. It will start listening on port 1246.

Client

The client library (both C++ and Python) support the following operations:

• clear()
• clor(r, g, b)
• pixel(x, y)
• rectangle(x, y, width, height)
• digit(position, digit) - to show a clock with up to 4 large digits
• smallText(x, y, text)
• largeText(x, y, text)
• defineImage(name, image) - in Python this expects an 8 bit PIL.Image (see Pillow)
• image(x, y, name)
• show()
