Firmware for the RP2040 that allows control of 1 or more daisy-chained LED Matrices over the Hub75 protocol.
Demos shown here are made using a pair of Adafruit 64x32 RGB LED Matrix - 4mm pitch
Requires CMake and GNU make.
In the project root, I run:
cmake -B build
cmake --build build/
Then plug in the Raspberry Pi Pico W in flash mode by holding the BOOT button before plugging in.
Then move build/ledmatrix.uf2 into the USB storage device that the Pico creates.
Connect to the device using the TCP console provided in tools/tcpconsole.py. It's currently hard coded to an IP address and port 2314.
start <app> // Starts an app by name as defined in src/Apps.hpp
forcequit <app> // Force quits an app by deleting the FreeRTOS task, does not perform any cleanup
msg <app_instance> <message> // Connects to an instance of an app as it appears in "listrunning" and sends a message
listrunning // Lists running processes
listapps // Lists all available apps
The script tools/pictureframe.py can be used to upload an image in a picture frame provided that you have already run start pictureframe in the tcp console.
A visually pleasing clock that retrieves time from an NTP server if you are connected
Displays static images on the screen in windows.
Add an image with msg pictureframe0 add <x> <y> <width> <height> followed by the raw BGR image data.
Two demos of the visual capabilities of the OS, both written by ChatGPT. They can be safely forcequit.
- Clock mode that pulls the current time from the internet using Network Time Protocol
- Send images over Wi-Fi to render to screen
- Render moving GIFs
- Render a 3d object file!! (Used as an open-ended final project for my computer graphics class)
