LinCAN 0.2 released

LinCAN is a set of CAN-BUS Cards drivers for LINUX and RTLinux developed as part of the OCERA project. The new version 0.2 includes a RTLinux realtime driver, a virtual board for test purposes and support for new cards.

LinCAN is a Linux kernel module that 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.
It supports RT-Linux, 2.2, 2.4, and 2.6 with fully implemented 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.
The driver has been successfully tested with following boards:
PC104 Advantech PCM3680 dual channel board on 2.4 RT-Linux enabled kernel, PiKRON ISA card on 2.4.and 2.6 Linux kernels, BfaD DIMM PC card on 2.4 RT-Linux enabled kernel, KVASER pcican-q on 2.6 Linux kernel, and the MICROSPACE msmcan on 2.4 Linux kernel with and without RT-Linux support.
The virtual board was also tested on all systems.
