4 CAN I/O Support

Introduction

xPC Target offers support to connect an xPC target system to a CAN network

using the CAN driver blocks provided by the xPC Target I/O block library. The

library supports the following CAN-boards from Softing GmbH, Germany.

For more information on the board specifications visit

www.softing.com.

The xPC Target CAN library intentionally restricts it’s support for Softing

boards with two CAN ports (boards with one channel would be available as

well). This is because the two port versions allow checking the correct

functioning of the board and drivers by just connecting the first CAN port to

the second CAN port. This forms a loop-back without having the need to

connect the board to a ‘real’ CAN-network. The xpcdemos directory

xpcdemos

contains simple loop-back test models to test the ISA, PCI and PC/104 boards.

Type the following commands to open the corresponding test models.

The size of the driver code of the CAN boards supported by the xPC Target

block library is significant and because not all xPC Target applications will use

CAN, the CAN library code is not linked by default when building a target

application. This makes target applications smaller if no CAN-communication

functionality is needed. If the model to be built contains CAN driver blocks, the

corresponding CAN-library support has to be enabled prior to the initiation of
