ANSI-C software modules to extend the CANopen Library functionality by special functions and other CiA profiles.

Besides the standardization of communication objects CANopen specifies application objects used in various device profiles. These device profiles guarantee a defined device behavior and provide thereby interchangeability of CANopen devices.

For employment of these profiles port provides extension modules for its CANopen Library. These modules make it possible to use the desired device profiles easily.

Currently port supports the following device profiles:

All modules are available in ANSI-C source code and can be used with all versions of the CANopen Library.

ANSI-C source code of an CANopen boot loader useful for easy In-System-Programming and firmware updates (not only for CANopen devices)

Modern device designs need enormous flexibility in hard- and software. Today hardware is equipped with plenty of resources in order to allow software changes later on. Software itself has to provide means to enable an update/upgrade of the current firmware. At this point in-system-programming offers the greatest possibilities, and thus a change of the software too.

Bootloader with a communication interface allow to do firmware updates by using an appropriate network.
Standardized communication objects and algorithms garuantee a high level of transparency and user friendliness.

The CANopen Gateway Server m4d is an universal CANopen Master application. It features a simple CANopen oriented command language according to CiA 309-3. The CANopen commands are accessible directly or over a TCP/IP socket interface.

The subject Ethernet access down to the fieldbus layer is intensely discussed. The CANopen Gateway Server provides the solution of Ethernet access down to the fieldbus layer right now and relies on the current and field proven CANopen technology.

The universal LINUX CAN device driver can4linux supports a broad range of CAN interfaces. ports AT-CAN-MINI is supported as well as a a bunch of interfaces from other manufacturers. Source code of the software is available. It compiles for Kernels 2.0, 2.2 2.4 and latest 2.6.

An derived version for embedded Linux-devices using micro controllers with integrated CAN or with external stand alone CAN controllers is available too. This one is configured at compile time for a specific hardware architecture.

can4linux is an universal LINUX™ device driver. It can be used to control ISA or PCI interface boards with CAN interface, or embedded CAN controller solutions. The GPLed sources are currently supporting CAN controllers (Philips SJA1000, Intel 82527, Infineon SAK82C900 and Motorola FlexCAN, TwinCAN). The driver can be compiled for all LINUX™ kernel versions 2.4 to 2.6. (older version for kernel versions 2.0 to 2.2 are available.)

The universal VxWorks CAN device driver can4vxworks supports a broad range of CAN interfaces.

The can4vxworks driver is a universal VxWorks device driver and is used for controlling of ISA-, PCI- and PC104 interface cards with CAN bus interface. It supports the CAN controller Philips SJA1000 and the sources can easily be adapted to use any other CAN controller .

With the J1939 server of port it is possible to get access to SAE J1939 network, maybe for diagnosis purposes. Therefore the provides a TCP/IP interface, which the connected client uses to exchange messages with other ECUs in the network. Instead the TCP/IP interface, the usage of the command line is possible too.

The demo version of J1939server for can4linux is available.

The J1939 Protocol Stack (in ANSI-C) is a complete implementation of the SAE J1939 protocol. By providing all communication mechanisms defined in the SAE J1939 specification the stack allows the developer to focus solely on the implementation of the application.

An adaption to other target systems can be performed easily within a few days due to the modular structure of the J1939 Protocol Stack based on the OSI layer model.
