The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
Dmx4linux is a driver package for accessing DMX interfaces with Linux. DMX is a protocol for controlling devices supporting DMX512 like dimmers, moving lights, or scanners. Many commercial and free interfaces are supported. The package includes some simple console and X applications to test the drivers and your hardware immediately.
lm_sensors provides essential tools for monitoring the temperatures, voltages, and fans of Linux systems with hardware monitoring devices. It contains a library for sensors access (libsensors), a command-line tool for sensor reporting (sensors), and a daemon (sensord). It also contains scripts for sensor hardware identification and fan speed control.
parapin makes it easy to write C code under Linux that controls individual pins on a PC parallel port. This kind of control is very useful for electronics projects that use the PC's parallel port as a generic digital I/O interface. Parapin goes to great lengths to insulate the programmer from the somewhat complex parallel port programming interface provided by the PC hardware, and comes as a user-space C library, or linked as part of a Linux kernel module.
DirectFB is a thin library that provides developers with hardware graphics acceleration, input device handling and abstraction, an integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer device. It is a complete hardware abstraction layer with software fallbacks for every graphics operation that is not supported by the underlying hardware.
rioutil is a utility designed for the use of interfacing with Sonic Blue/dnna's third, fourth, and fifth generations of flash MP3 players (Rio 600/800/900/S-Series/Riot/Cali/Chiba/Fuse and Nike psa[play). On many players, it goes beyond the packaged software by providing downloading.
Sand Kit contains libraries designed for neural networks training and calculations, and a Linux kernel module for the SAND board neuro accelerator. The calculation library supports Multi Layer Perceptron (MLP), Radial Basic Function (RBF), and Kohonen networks in hardware acceleration mode and MLP and RBF networks in software emulation mode. It provides a C++ class library and simple C routines for neural network calculations. It has a flexible configuration which includes setting the maximum permitted memory usage, calculation and memory usage optimization options, input and output data sources, and debugging options. The configuration can be changed simply by editing the configuration file and/or with the built-in Gtk+ user interface. The learning library provides a flexible way to write new learning algorithms and methods using a powerful modules library. It contains several common learning routines, including an enhanced random search and resilient backpropogation algorithms. It is integrated with the calculation library to use software as well as hardware modes. All methods have separate configuration files. Support for interface plugins is provided, and all learning routines have built-in Gtk+ interface plugins.
