TDA4VH-Q1: Implementing Capture node timestamp in nanoseconds

Part Number: TDA4VH-Q1

Tool/software:

Hi,

For now in our project we are receiving timestamps from raw image descriptor from viss node in micro seconds can we get the timestamp in nano second precision?

I can see the usage of tivxPlatformGetTimeInUsecs Api is there any alternate api for this purpose ?

What are the steps we need to follow to achieve this?
Kindly guide me through the process.

    hi,

    Well, it uses GTC timer, which is running at 200MHz, so you could probably get the timestamp at 5ns interval only.. You could add another API like tivxPlatformGetTimeInNsecs and use it in the node where you require ns timestamp.
