CAN-AC2-PCI
The CAN-AC2 is a PCI-board, and the hardware interrupt line is automatically assigned by the PCI BIOS during the boot-up of the target system. Use the xPC Target function `getxpcpci' (see `help getxpcpci') at the MATLAB command prompt to query the target system for installed PCI devices and the assigned resources. Write down the interrupt line number assigned to the CAN-AC2-PCI board.
- In the Simulink window, and from the Tools menu, point to Real-Time Workshop, and then click Options. Select the category "xPC Target code generations options" in the displayed dialog box. In the "Real-Time Interrupt Source" pop-up menu select the interrupt line number which you have retrieved by calling `getxpcpci'. Close the dialog box and save the model.
- Open the dialog box of the CAN Receive block in the model which defines the CAN-message (identifier) to be used to fire the interrupt. Check the Generate interrupts check box. Checking this box will declare all CAN-messages defined in this Receive block instance through their identifiers as messages, which will fire an interrupt. Or in other words it is not possible to define a single CAN-message within the set of defined identifiers to be the only one to fire an interrupt. In most cases only the reception of one specific message is used to drive the application execution. Therefore use at least two instances of the Receive block. One to receive the CAN-message, which drives the execution (Generate Interrupts checked) and the other for all other "normal" CAN-messages to be received (Generate Interrupts unchecked).
