CANpie defines a Standard API for access to the CAN (Controller Area Network) bus. The API provides functionality for ISO/OSI Layer 2 (Data Link Layer). The CANpie driver is the base for HLPs like CANopen, DeviceNet, J1939, etc. Through its low memory footprint, CANpie can be used for embedded applications (without any OS) as well as for Linux. Access to the Linux CAN driver is via a socket interface (AF_CAN).
Linux device driver for CueCat barcode readers that supports multiple PS/2 CueCats on either the keyboard port, mouse port (without disabling the mouse) or USB port through a PS/2 -> USB adapter, or native USB CueCats. A standalone application that doesn't require the driver and also reads barcodes from a CueCat connected to a serial port through a homemade PS/2 -> serial converter is included as well. The driver separates CueCat barcode scancodes from normal keyboard or mouse scancodes, decode the barcodes, performs error-checking on them and send them in clear text through a normal character device file. NOTE : the company that created the CueCat has disappeared. CueCat readers are no longer produced or distributed.
Device::ParallelPort is a Perl API that allows low level access to the parallel port of most computers. It does this by using a number of drivers, which can be customized and added to, including Linux (direct and parport), Win32, Script, Dummy, and more. It also contains a number of direct access devices including an example printer and a relay controller card.
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.
JTAG Tools is a software package which enables working with JTAG-aware (IEEE 1149.1) hardware devices and boards through a JTAG adapter. This package has an open and modular architecture with the ability to write miscellaneous extensions like board testers, flash memory programmers, and so on.
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.
MuProg is a user space program for programming Atmel AVR microcontrollers. It needs the katmel kernel driver. This application can program the fuses, lock bits, EEPROM, and the flash ROM. It reads hex files. Most AVR microprocessor types are supported and automatically identified by requesting the Chip ID (if supported).
