Why do I receive a callback error when I try to run the "Sine Wave Generator using RTDX" demo in Link for Code Composer Studio?

I receive the following callback error when I try to run the "Sine Wave Generator using RTDX" demo in Link for Code Composer Studio:

 Error evaluating ‘OpenFcn’ callback: of Run demo block (mask) ‘c2812rtdxtest/’. CCSDSP:CCRtdx: COM wrapper object is not valid.

This enhancement has been incorporated in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

You can receive this error message when RTDX is not being set up correctly or your target does not support RTDX. The Link for Code Composer Studio Development Tools cannot determine whether RTDX is properly configured and if the target supports RTDX operations.

To work around this issue and avoid the error:

1. Verify that your target supports RTDX before running the demo. If it does not, obtain a target that does support RTDX.

2. Make sure that you set up RTDX properly, remembering to both configure and enable RTDX channels.

You can use the ISRTDXCAPABLE function in Link for Code Composer Studio to check whether your target supports RTDX. For more information about function ISRTDXCAPABLE, refer to the documentation by entering

doc isrtdxcapable

at the MATLAB command prompt.

For more information about setting up/configuring RTDX, refer to the Link for Code Composer Studio Development Tools documentation in the online Help system.
