MATLAB: Is it possible to configure or change CAN Identifier settings in the Embedded Target for Motorola MPC555

Target Support Package FM5

I would like to change CAN identifiers from 29 bit identifiers to 11 bit identifiers. What file or action do I need to change to get the MATLAB downloader to send 11 bit identifiers?

Best Answer

The MATLAB downloader (Embedded Target - Download Control Panel) uses 29-bit identifiers by default and this is hard coded into the implementation of the Download Control Panel. Hence, this feature to change CAN identifiers from 29-bit to a different size is not available.
To workaround this issue, you can perform one of the following actions:
1) Use an additional MPC555 development board and develop a Simulink model using the embedded target which converts 29-bit message identifiers to 11-bit message identifiers and connect this to the intermediate CAN node.
or
2) Purchase additional CAN hardware to convert the CAN identifiers.
