BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides minimalist replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete POSIX environment for any small or embedded system.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
emlog is a Linux kernel module that makes it easy to access the most recent (and only the most recent) output from a process. It works just like "tail -f" on a log file, except that the storage required never grows. This can be useful in embedded systems where there isn't enough memory or disk space for keeping complete log files, but the most recent debugging messages are sometimes needed.
EVBU simulates the execution of a 68HC11 microcontroller as well as the BUFFALO monitor program that provides a command line interface to executing and debugging programs. A graphical waveform panel allows simulation of 68HC11 peripherals like timers, input capture, etc. Additional features include symbolic debugging and cycle counting.
MiniGUI is a mini graphical user interface (GUI) support system for Linux that provides an event-driven API for applications. It makes it possible for an application to create multiple windows in multiple threads, and can draw in these windows without interfering with each other. A Graphics Abstract Layer (GAL) and an Input Abstract Layer (IAL) are provided for compatibility with many graphics engines, including SVGALib, LibGGI, and X. It provides native support for many image types including GIF, JPG, PCX, LBM/PBM, and BMP, TrueType and Adobe Type1 fonts, and GB2312 and BIG5 charsets.
SRecord is a collection of powerful tools for manipulating EPROM load files. It understands a number of file formats including Motorola S-Record, Intel hex, Tektronix hex and binary, for both input and output. SRecord filters include cropping, filling, splitting, joining, and more. All filters may be applied to all file formats.
TinyLogin is a suite of tiny UNIX utilities for handling logins, user authentication, changing passwords, and otherwise maintaining users and groups on an embedded system. It also provides shadow password support to enhance system security. TinyLogin is, as the name implies, very small, and makes an excellent addition to an embedded system.
Originally named Sync4j, the Funambol Mobile Application server includes a suite of tools to develop, deploy, and manage mobile projects. It includes push email functionality and is a certified implementation of SyncML (OMA DS/DM standard). It includes a mobile application server with connectors to SQL relational databases, Microsoft Exchange, Lotus Domino, and SugarCRM, applications for Outlook, Windows Mobile PocketPC, BlackBerry, Palm, and iPod for synchronizing address books and calendars, and a gateway for supporting mobile email. An SDK and an OMA DM server for remotely managing mobile devices are also included.
Seminole Webserver is a portable Web server designed to be used in embedded systems, where memory space is at a premium. It is written in C++, and has a mechanism to direct requests to application-specific code, complete with the decoding of "CGI" parameters. It also includes a "filesystem" that can package up Web content (and optionally compress it) and store it in a ROM or other "flat" device. It comes with a simple example to make it a standalone Webserver under POSIX platforms for evaluation and testing.
