How does labvIEW continuously write data to excel?

Write electron** There is another terminal that you didn't notice.

1) Add to file, Boolean, default to false when not connected, means that the new content overwrites the original content, change to true to solve the problem of continuous writing.

2) Transpose, Boolean, is used to adjust whether the write is written in rows or columns.

1. Configure the Word template. Open Word to create a template frame, then click "Insert" and find "Bookmarks" under the "Insert" menu. Configure it further in Bookmarks.

2. Add the bookmarks you need in "Bookmarks". This is shown in the figure below.

3. Configure the excel template. Similar to the steps above, configure it in the text box. The configured Excel template is shown in the following figure.

4. The first method of Labview call template: use the MS Office Report toolkit. The following figure shows the methods, steps and procedures for using MS Office Toolkit to invoke templates.

5. The second method of Labview call template: use a single function to generate reports (Excel as an example). The following figure shows the methods, steps, and procedures for invoking MS Office toolkit to operate and using a single function to generate reports (Excel as an example).

1 First of all, you need to use the function of file io to read the electronic ** file, and read the data in the txt file into a two-dimensional array.

There are two columns, the first column is the x-axis data, and the second column is the y-axis data.

2 The first of the two index ends of the second index array function is also connected to the for loop.

i(repeatterminal), but the second end is connected to the constant 1, and then the output of the two functions is connected to both ends of the bundle.

3 Here the for loop also needs to hold the reed to access an n (loop terminal). First, connect the input two-dimensional array to the array size function. Source repentance.

4 Then connect the output terminal to the index array. At this point, only one index is connected to the constant 0 and the output is connected to n.

1. First of all, prepare the "sample data" excel** for LabView reading, as shown in the figure below.

2. Switch to the front panel, click the folder icon of the "Select Sample Data ** Path (Excel Sheet)" control, select the "Sample Data" Excel you just created, and click "OK".

3. After selecting the sample data path (excel sheet), run the LabVIEW program, you can see that the "Sample Data Read" control shows the data read from the sample data, as shown in the following figure.

4. If the format of "read sample data" does not meet the requirements of subsequent operations, and you need to transpose it, you can use the "two-dimensional array device" control to transpose **, and the array transposition program and transpose result are shown in the following figure.

5. Next, convert the string data ** (array) into a numeric ** (array), and use the "decimal number string to numeric conversion" function control to convert the data type.

**The display control is a type of control with a slow refresh rate, which is indeed easy to cause flickering, and there are several ways to improve flickering:

a) If the system does not have high requirements for the sampling rate, add a delay, generally when the delay is 300ms or more, it will not flicker.

b) If the system can't delay for such a long time, please right-click on the [**Display Controls] on the front panel, select the first row of [Display Items], and remove the checkboxes of [Vertical Scrollbar] and [Horizontal Scrollbar], which will significantly improve the flashing.

c) Another way is to add a case structure, put [**] in [case], and refresh ** every 500ms**.

Another way is to use a string display control. This widget refreshes very quickly and doesn't have any flickering, but it has two drawbacks, the first is that the strings need to be pre-concatenated, and the second is that there are no ** lines.

Below is the attached drawing:

Figure: Latency of 300 ms.

Figure: Cancel the vertical and horizontal scrollbars.

Figure: Refresh every 500 cycles.

Figure 2: Replace the ** with a string display control.

The image below is the effect:

I think you should look at your question first. It's also a little easier to understand.

1. Configure the Word template. Open Word to create a template frame, then click "Insert" and find "Bookmarks" under the "Insert" menu. Configure further in the Stove Bookmark.

Add the bookmarks you need in Bookmarks. This is shown in the figure below. Configure an Excel template.

Similar to the steps above, configure it in the text box.

2. In fact, this operation is divided into two steps, the first step is to write the title of each column, and the second step is to convert the data format into a string array and then write **. If there is only a hidden potato number data without a string (such as da01), you can store it in the data format in the second step without conversion.

3. Use the write electron** function to write electron** directly to the txt document, when the suffix of the hand-based orange file is changed to xls, it will be associated with excel by default, and it will be like that. With the report toolkit, you can write it in Excel, and you can also customize the template and write it however you want.

Configure the Word template. Open Word to create a template frame, then click "Insert" to find the "Bookmark" of which filial piety under the "Insert" menu. Configure it further in Bookmarks.

Add the bookmarks you need in Bookmarks. This is shown in the figure below. Configure an Excel template.

Similar to the steps above, configure it in the text box.

The solution is to save it in txt format, which can then be opened with your existing excel. This one is the same.

It is recommended to use TDMS files to save the collected data in LabVIEW, TDMS files are very convenient to save and read, and Excel is generally used to generate reports in LabVIEW.

Use the write electron ** function to write electron directly to the txt document, when the suffix of the document is changed to xls, it will be associated with excel by default, and it will be like that. Use the report toolkit, so that you can write it in Li Pai excel, you can also customize the template, and you can write how you want.

First, make sure that the back panel of Labview has a module to display array data; 02 Back to the front panel, this is a one-dimensional array that can be placed with the Warp tool. 03Make sure there is no problem with the program and click run so we can get the data.

Replace the constants in the graph with your time string and the values you read, and put your visa reads and writes in this loop.
