About:
The dcled package provides a Linux kernel driver and userspace utilities for the Dream Cheeky USB message board, commonly known as the 'USB Roll Up Message Board'. It enables programmatic control over the device's LED matrix, allowing developers to display custom text, scrolling messages, and visual alerts directly from the command line or scripts.

Key Features:

Kernel driver for seamless device integration
Command-line utilities for sending messages and controlling LEDs
Support for scrolling text and custom patterns
Scriptable interface for automation

Use Cases:

Displaying system monitoring alerts (CPU usage, disk space, errors)
Creating custom status boards for CI/CD pipelines
Sending notifications from scripts or cron jobs
Building IoT-style visual indicators

Alternatives:

lcdproc – Supports a wider variety of LCD displays but may be overkill for single USB message boards
libusb-hid-reports – Requires manual HID protocol implementation; dcled provides device-specific abstractions
