RTOS: What is subframe for in capture link?

Byeongheon Yoo

Tool/software: TI-RTOS

Hi,

I'm looking over captureLink_drv.c.

In that source, there is 

```

if(pInst->isSubframeEnabled)
{
CaptureLink_subframe_drvAllocAndQueueFrames(pObj, pInst);
}
else
{
CaptureLink_drvAllocAndQueueFrames(pObj, pInst);
}

```

Could you explain the role and how it used in capture link?

Thanks.

Regards,

Yoo.

    Hi Yoo,

    It depends upon whether you want to capture a full frame or you want to capture a part of it i.e. sub-frame before getting the interrupt.

    Both are different use cases and driver, queues, etc. need to be configured differently in both the cases.

    You can ignore it for now.

    Hi,

    I haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
