Its official page frames the project as a Linux-style way to stream text to the device. ### Project history The author wrote the first version after finding a hardware developer manual for the device. The official page says version 1.0 took roughly a Saturday afternoon, and the program was shaped to behave like cat: files go to the display, stdin works as a pipe, and a message option handles one-off text. The project then accreted features from real desk and server use. Preamble graphics were added because the author missed the beginning of scrolling messages, and later releases moved from libhid to direct libusb use and added a tachometer mode for gauge-like displays. ### Adoption history dcled is niche hardware software rather than an ecosystem project. The official page records use for monitoring a game server, Mac OS X compatibility, and a related Ruby userland driver by another developer, which is about the right adoption scale for a single USB novelty device. ### How it is used The practical pattern is Unix plumbing: pipe log output or short status messages into dcled and let the LED board scroll them. The page's example tails a system log through dcled with preamble graphics and echoing enabled so the same text appears on both the terminal and the display. Options cover brightness, clock display, preambles, repeated scrolling, font selection, speed, test patterns, and a no-device mode, which makes it more scriptable than the toy hardware would suggest. ### Why package nerds care dcled is the kind of package that makes old Unix package indexes fun: one odd USB object, a single-purpose CLI, no daemon, no cloud account, and just enough stream behavior to make it composable. ### Timeline - Initial version: Written after the author found the Dream Cheeky hardware developer manual. - 2011: The page records discussion of a related Inland USB LED badge tool. - 2012: dcled 2.1 replaced the libhid layer with direct libusb use. - 2014: dcled 2.2 added tachometer mode and an included cpuload helper. ### Related projects - The official page links to Lewis Clayton's Ruby userland driver for the same Dream Cheeky USB LED Message Board and to an Inland USB LED Badge control project. ### Sources - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** dcled - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Web development packages](https://www.automicvault.com/pkg/web-dev-tools/) - Matched web development metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [usbutils](https://www.automicvault.com/pkg/brew/usbutils/) - Shares av.db curated category or tags: cli, hardware, linux, system, usb. - [cyme](https://www.automicvault.com/pkg/brew/cyme/) - Shares av.db curated category or tags: cli, hardware, system, usb. - [libusb-compat](https://www.automicvault.com/pkg/brew/libusb-compat/) - Shares av.db curated category or tags: cli, hardware, system, usb. - [lsusb](https://www.automicvault.com/pkg/brew/lsusb/) - Shares av.db curated category or tags: cli, hardware, system, usb. - [rkflashtool](https://www.automicvault.com/pkg/brew/rkflashtool/) - Shares av.db curated category or tags: cli, hardware, system, usb. - [ddcutil](https://www.automicvault.com/pkg/brew/ddcutil/) - Shares av.db curated category or tags: cli, linux, system, usb. - [digitemp](https://www.automicvault.com/pkg/brew/digitemp/) - Shares av.db curated category or tags: cli, hardware, system. - [dpcmd](https://www.automicvault.com/pkg/brew/dpcmd/) - Shares av.db curated category or tags: cli, hardware, system. ## Combined YAML source View the package source record on GitHub.
