Its copyright block covers 2003-2013, with later SourceForge code revisions reaching lpc21isp 1.97 in January 2014. The project lived in the classic SourceForge/SVN era of embedded open source: small C sources, Visual Studio and GCC build notes, and a project page oriented around downloads, code browsing, and a simple web site. ### Adoption history Homebrew, Debian, Ubuntu, and MacPorts package lpc21isp according to the supplied package-manager facts, which is typical for embedded utilities that remain useful long after active upstream development slows. SourceForge categorizes the project for developers and command-line use, and downstream ports describe it as an ISP programmer for NXP LPC microcontrollers. ### How it is used Package users install the `lpc21isp` executable and use it from scripts or terminal sessions to transfer a firmware image through a supported serial bootloader. It has no documented project configuration or credential file. ### Why package nerds care lpc21isp matters to package maintainers because it is one of the small hardware bring-up tools that turns a Unix package manager into a practical embedded workstation. Its value is not broad desktop popularity, but being available when a board needs serial ISP flashing. ### Timeline - 2003: Official README copyright period begins for lpc21isp. - 2008: SourceForge SVN history shows the initial imported project files. - 2014: SourceForge code browser shows lpc21isp 1.97 revisions. - 2026: Supplied package-manager facts list Homebrew, Debian, Ubuntu, and MacPorts packages. ### Related projects - Related tools include vendor flash loaders, OpenOCD for debug-adapter workflows, and other serial bootloader utilities for microcontroller families. ### Sources - - - - source_facts.package-manager ## 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:** lpc21isp - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - lpc21isp - 1.97-4+b1: normalized package name match | Debian stable package indexes: lpc21isp from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | In-circuit programming (ISP) of ARM and Cortex microcontrollers | http://sourceforge.net/projects/lpc21isp/ - Ubuntu apt - lpc21isp - 1.97-4: normalized package name match | Ubuntu 24.04 LTS package indexes: lpc21isp from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | In-circuit programming (ISP) of ARM and Cortex microcontrollers | http://sourceforge.net/projects/lpc21isp/ - MacPorts - lpc21isp: normalized package name match | MacPorts ports tree: cross/lpc21isp/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [teensy_loader_cli](https://www.automicvault.com/pkg/brew/teensy-loader-cli/) - Shares av.db curated category or tags: cli, developer-tools, embedded, firmware, microcontroller. - [bossa](https://www.automicvault.com/pkg/brew/bossa/) - Shares av.db curated category or tags: cli, developer-tools, embedded, microcontroller. - [gpsim](https://www.automicvault.com/pkg/brew/gpsim/) - Shares av.db curated category or tags: cli, developer-tools, embedded, microcontroller. - [gputils](https://www.automicvault.com/pkg/brew/gputils/) - Shares av.db curated category or tags: cli, developer-tools, embedded, microcontroller. - [mspdebug](https://www.automicvault.com/pkg/brew/mspdebug/) - Shares av.db curated category or tags: cli, developer-tools, embedded, firmware. - [elf2uf2-rs](https://www.automicvault.com/pkg/brew/elf2uf2-rs/) - Shares av.db curated category or tags: cli, developer-tools, embedded. - [espflash](https://www.automicvault.com/pkg/brew/espflash/) - Shares av.db curated category or tags: cli, developer-tools, embedded. - [jaguar](https://www.automicvault.com/pkg/brew/jaguar/) - Shares av.db curated category or tags: cli, developer-tools, embedded. ## Combined YAML source View the package source record on GitHub.
