SOCKET-BASED CAN SUPPORT FOR EMBEDDED OPERATING SYSTEMS

The Controller Area Network (CAN) has been adopted as the network communication technology of choice in many real-time application domains. Due to the ever increasing sophistication of contemporary embedded controllers, it becomes both possible and convenient to access this kind of network by means of a well-known and standard application programming interface instead of resorting to an ad hoc framework. This paper describes the addition of CAN support to the eCos embedded real-time operating system, from the device interface layer up to the extension of its network communication modules, based on Berkeley sockets.
