history

Project history and usage

lpc21isp is a portable command-line in-system programming tool for flashing firmware to NXP LPC-family and Analog Devices ADUC70xx microcontrollers over their serial bootloaders.

Project history

The official SourceForge README identifies Martin Maurer as the author and describes the project as a portable command-line ISP for the NXP LPC family and Analog Devices ADUC70xx. 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.
