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.
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.
v4l-utils is a collection of various video4linux (V4L) and DVB utilities. libv4l is an accompanying collection of libraries that adds a thin abstraction layer on top of video4linux2 (V4L2) devices. The purpose of this layer is to make it easy for application writers to support a wide variety of devices without having to write separate code for different devices in the same class. It consists of 3 different libraries. libv4lconvert offers functions to convert from any (known) pixel format to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420. libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent of the drivers for those devices supporting v4l1 compatibility (which many v4l2 drivers do not). libv4l2 offers the v4l2 API on top of v4l2 devices, while adding support for the application transparent libv4lconvert conversion where necessary.
Smart Card ToolKit provides a library and associated tools for smart cards. Phoenix and Smartmouse protocols are supported for ISO7816 asynchronous smart card access and debugging. JDM is supported for programming PIC-based smart cards like piccard, goldwafer (goldcard), and silvercard. SPI is supported for programming AVR based smart cards (funcard). PIC and AVR loaders provide access to external i2c EEPROM. I2c memory smart cards are also supported. All tools use Intel hex file format to store data. An Intel hex to binary and vice-versa converting tool is also provided.
WinDriver automates and simplifies the development of user-mode Linux device drivers for PCI, CardBus, ISA, PMC, PCI-X, PCI-EXPRESS, and CompactPCI as well as USB 1.1/2.0. No internal OS knowledge or kernel level programming is required. It supports kernel 2.0.31 and above, including embedded Linux, x86 and PowerPC processors, and any 32-bit development environment supporting C or Delphi. Applications are source code compatible across Windows 98/Me/NT/2000/XP/XP Embedded/Server 2003/CE, Linux, Solaris, and VxWorks.
LinCAN is a Linux kernel module which implements a CAN driver capable of working with multiple cards, even with different chips and IO methods. Each communication object can be accessed from multiple applications concurrently. The driver supports Linux 2.4.x, 2.6.x, and 3.x kernels and implements select, poll, fasync, O_NONBLOCK, and O_SYNC semantics and multithreaded read/write capabilities. It works with the common Intel i82527, Philips 82c200, and Philips SJA1000 (in standard and PeliCAN mode) CAN controllers. It is part of a set of CAN/CANopen-related components developed as one of the OrtCAN project components.
OpenCT implements driver and middlerware for smart card readers. OpenCT drivers can be used via the ct-api interface, the ifdhandler interface, or its own interface/middleware. It implements drivers for several USB crypto tokens, USB smart card readers, serial smart card readers, and PCMCIA smart card readers.
