HDC2010EVM: Could we add time information in the output CSV file using GUI like HDC3020?

Part Number: HDC2010EVM
Other Parts Discussed in Thread: HDC3020, HDC2010,

Hi 

Customer wants to record time information of sampling data from GUI to CSV file like adding timestamp.

In HDC3020, it can be achieved. Could we record the time information to CSV file when using HDC2010?

By the way, what is the meaning of these data?

Thank you，

Yishan Chen

    Hi Yishan,

    I am working to obtain an EVM so I can check the GUI and address these questions. I should get back to you tomorrow!

    Hi Yishan,

    Unfortunately the HDC2010EVM GUI does not log the time stamp, however it does log the sample serial number "x" and "logDeltaMs". The time stamp can be calculated from those 2 logs. 

    "logDeltaMs" (the data you highlighted) is the time-delta in msec between the consecutive measurements. This data should match the Data Sample Rate (it might be a bit larger due to communication delays). You could sum the data in this column to get the total elapsed time from the first measurement.

    You could also calculate the time stamp from the sample serial number "x" by multiplying it with the Data Sample Rate.

    I would advise to match the Data Sample Rate (set under Data Streaming tab > Graph Configuration) to the configured Output Data Rate (set on the Configuration tab). Please see screenshots below.

    Best regards,
