AA-lib is a low level gfx library just as many other libraries are. The main difference is that AA-lib does not require graphics device. In fact, there is no graphical output possible. AA-lib replaces those old-fashioned output methods with a powerful ASCII art renderer. The API is designed to be similar to other graphics libraries.
DataReel is a free, cross-platform database and communications toolkit. It can be used to rapidly develop and deploy multi-threaded database and communications applications. The DataReel toolkit is composed of a modular C++ library designed to build cross-platform infrastructures for end-user applications, embedded systems, and reusable libraries. DataReel's unique modular design simplifies adaptation, allowing you to determine the level of complexity. DataReel makes Internet connectivity and database programming easy.
PerlDAV is a Perl library for modifying content on Web servers using the WebDAV protocol. Now you can LOCK, DELETE, and PUT files, and much more, on a DAV-enabled Web server. The PerlDAV library consists of: HTTP::DAV, an object-oriented Web- DAV client API, dave, the DAV Explorer, an end- user UNIX console program for interacting with WebDAV servers (dave looks and feels like a standard UNIX ftp program).
Palm SV203 Serial Control Library was designed to send commands and receive analog-to-digital sensor input from a Pontech SV203 microcontroller board. It consists of one class and several support files. It has functions to control all servo functions (absolute move, incremental move, zero pulse, direct digital pin set/clear/toggle) and analog-to-digital sensor inputs. There is also a test program which utilizes most/all functionality of the library; it can be run standalone on the Palm to test an SV203 board.
