tdms | Ruby library to read files in NI TDMS format

So I ended up contacting the author and he was helpful enough to send a response:

TDMS files internally store times in UTC. You don't say how you're getting the values in the "TDMS file" column but I assume this is from a program that converts times into your local timezone to display them. There is an example of how to convert UTC times from a TDMS file into your local timezone in the documentation.

If you are storing these times in a database though, I would strongly recommend you store times in UTC rather than your local timezone as local times can be ambiguous due to daylight savings changes, and UTC is easily understood from anywhere in the world without having to know the local timezone where the data originated.

If you still feel like making the change from UTC to EST then this should do it:

dask.bytes.read_bytes() will give you whole files if you use blocksize=None, i.e., exactly one block per file. The most common use case for that is compressed files (e.g., gzip) where you can't start mid-stream, but should work for your use case too. Note that the delayed objects you get each return bytes, not open files.

Alternatively, you can use fsspec.open_files. This returns OpenFile objects, which are safe to serialise and so you can use them in dask.delayed calls such as

I got it working finally. Now my Nexys Video card passes through a Full HD video. Here are the details:

1. Both HPA and TXEN pins must be set to '1'. In my case I assigned HPD pin of the source port to the HPA pin of the sink port. Checking the board schematic, the HPD pin is tied to an open drain MOSFET, so it must be inverted before the assignment.

assign HDMIR_HPA = ~HDMIT_HPD;

1. Additionally, after a thorough googling, I found that bridging DDC SCL and SDA pins of sink port to source port seems to be impossible as two bidirectional pins cannot be (simply) wired on FPGAs. So the solution to the problem is adding an EDID ROM emulator to the sink side. Then the FPGA itself behaves as a monitor to the video source device (i.e. the PC in my setup).

I found a VHDL implementation of EDID ROM from here. It emulates a 1024 x 768 monitor, however I changed it to 1920 x 1080.

This is the revised code for the top module:

The method you are referring to exists in the current documentation so it would make sense to

1. Restart the virtual environment (close cmd line; start again; conda activate ).

If this does not help...

1. Reinstall the package:

   conda remove nptdms

   conda install nptdms

(the exact commands may differ depending on your environment).

If this does not help, create a fresh conda environment and install from scratch and check again.

When you write Set wbSource = Workbooks.Open(myfile), myfile becomes the active workbook. The active worksheet will be whichever worksheet was active when the workbook was last saved.

You next write Columns("A").Replace ... . This statement operates on the active worksheet. If the wrong worksheet is active, this statement will not have the effect you seek.

If my guess about the cause of your problem is correct, try Worksheets("xxx").Columns("A").Replace ... where "xxx" is the name of the worksheet containing the column you wish to change.

Edit 1

I find it difficult to understand what is going wrong. You say the name of the worksheet is “Values” but when you try to access that worksheet you are told it does not exist. I will try to explain Workbooks, Worksheets and related terms.

Suppose you open workbooks “A.xlsx”, “B.xlsx” and “C.xlsm”. It is possible to open “A.xlsx”, “B.xlsx” and “C.xlsm” each in their own copy (instance) of Excel.exe, but this is not easy. Normally, there will be one instance of Excel.exe “containing” three open workbooks. Workbooks is a collection or list of the open workbooks within an instance of Excel.. A macro within “C.xlsm” could contain:

Here you go =^..^=

You can use this code to check if a file is empty:

This is not using Python. But a simple batch script "type" can append all the file to txt oor csv file. Try this in command prompt pr save the code as filename.bat:

As explained in the documentation, you can read the metadata directly using nptdms.TdmsFile.read_metadata
