Timestamp TULIP Virtual Port Feeds - rocket.scientist - 10-24-2024 07:59 PM
Can each line in the various serial feeds be timestamped somehow - console, tracer and HP-il scope? I am doing a lot of correlation between different feeds right now. It is hard to match up where a HPIL transaction happens in the tracer feed. Maybe make this an option that can be turned on / off?
If this is not the best spot for a feature request, please redirect me.
Thanks for the consideration.

Best is to add an issue to the TULIP DevBoard GitHub page. But I can do that if you do not have an account there.
In the console I do not think a timestamp adds any value. For the traces it certainly does. I can add the samplecount (first column in the tracer) to the HP-IL scope, so there is a easy cross reference. There will be some jitter in the counter (HP-IL scope data is generated in the non-critical core) but I estimate this is not too much.
A clock will be a bit of a hassle, and there is not battery backed RTC on the device. A disadvantage of the sample counter is that it resets after every power event.

Using the samplecount will help immensely, thank you. Right now I am using the cdcident command to bookmark the feeds, and that is w-a-y too granular.
I will add an issue in the github.

Got the issue.
