Retrieving Event and Mailbox Handles from cfg script?

Other Parts Discussed in Thread: SYSBIOS

I have events and mailboxes defined in the cfg script like so:

var event0Params = new Event.Params();
event0Params.instance.name = "eventBC";
Program.global.event0 = Event.create(event0Params);

var mailbox0Params = new Mailbox.Params();
mailbox0Params.instance.name = "mailboxBC";
mailbox0Params.readerEvent = Program.global.event0;
mailbox0Params.readerEventId = 0x1;
Program.global.mailbox0 = Mailbox.create(128, 4, mailbox0Params);

How do I get the handle for these events?

    Hi Darrell Faber,

    You should have a global C variable accessible in your application based on the "Program.global.<variable name>" name.

    The content of the *.cfg file is used to generate a .c file that's then built into your application.

    This generated .c file is found under the Debug or Release folder in your project.

    For example:

        Debug/configPkg/package/cfg/<project name>_<isa>.c

    So the mailbox code you have above:

        Program.global.mailbox0 = Mailbox.create(128, 4, mailbox0Params);

    Should cause something similar to the following to be generated in that .c file:

        const ti_sysbios_knl_Mailbox_Handle mailbox0 = (ti_sysbios_knl_Mailbox_Handle)((ti_sysbios_knl_Mailbox_Handle)&ti_sysbios_knl_Mailbox_Object__table__V[0]);

    I found that declaration in the generated .c file, however I am still unsure how to use this. mailbox0 is undefined when I try to use it.

    Nevermind, added the extern declaration, and it works now. Thanks for your help.
