LAUNCHXL-F280049C: Creating SYS/BIOS Queues

Part Number: LAUNCHXL-F280049C
Other Parts Discussed in Thread: SYSBIOS

Referencing SYS/BIOS documentation vbios_6_83_00_18

The ti>sysbios>knl>Mailbox module includes a Mailbox_create function that accepts a msgSize and numMsgs and handles the storage internally.

whereas

the ti>sysbios>knl>Queue module includes a Queue_create function but does not include any way to pass a msgSize/numMsgs. Is there any way to use the Queue module with the storage handled by it?

Thanks in advance

Mailbox allocates memory for its Queue elements--it manages that aspect for you. If you're just using Queue on its own, your application manages where the data is stored. There's a little code example in the Queue chapter of the SYS/BIOS API reference where the application just declares a few structures: https://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/bios/sysbios/6_76_04_02/exports/bios_6_76_04_02/docs/cdoc/ti/sysbios/knl/Queue.html#xdoc-desc
