iSystem daqIDEA It is a simple but effective graphical presentation tool for large data sets . It will be different The value of the variable Displayed in the 2D Chart and Numerical table in .

Acquired data Can be exported to a file , Variable configurations can be saved to configuration files . You can examine the chart carefully by scaling and stretching , If you ignore it , The maximum number of up-to-date data... Will be displayed .

daqIDEA from winIDEA Start in environment .

1 open iSystem daqIDEA

stay winIDEA In the menu bar , Choose in turn Test –> Launch daqIDEA, See the picture 1-1.

  chart 1-1

Be careful ：

First boot , Warnings about missing configuration files will appear , See the picture 1-2. This profile is created by daqIDEA establish , Contains the variable name and other settings from the previous session .

2 How to use iSystem daqIDEA debugging

In the pop-up iSystem daqIDEA In the dialog box , single click Add Variable Button , Add the... To be observed C Code variable name , See the picture 2-1.

notes ：

Application control Introduce ：

  In order to prevent daqIDEA and winIDEA Switching between , You can use the three buttons in the upper right corner for simple application control .

1. Download (F5) – take winIDEA The executable specified in the workspace is downloaded to the destination .
2. Run (F6) – Start / Restore application execution on target .
3. Stop (F7) – Stop application execution on the target .

stay Stop Button The right side of the , There is the running state of the current application .

Data Acquisition Control Introduce ：

  The three buttons above control the execution of the actual application running on the target system , The three buttons under the variable configuration table are used to control data collection .

1. Start/Resume (F9) - Start data collection for the variables specified in the variable configuration table . If our variable name is invalid , A warning appears at the bottom of the table , And the collection process will not continue .
2. Pause (F10) - This does not actually stop data collection , Because the process continues in the background . The purpose of pause is to observe the collected data displayed on the chart . Chart animation can be started by clicking again / Restore button to restore
3. Stop (F11) – Stop data collection . Click start / Resume button , Acquired data will be lost , The whole process will restart .

The following figure is shown below 2-2 Added 3 Take variables as an example .

  chart 2-2

notes ：

1. Sampling： Set the data sampling interval for each variable to one of four values ： 1 second 、100 millisecond 、10 Milliseconds or 1 Milliseconds or the maximum possible acquisition speed （ It certainly depends on the speed of the target processor and other system parameters ）;
2. Variable name：C Code variable name ;
3. Chart：daqIDEA Charts are used in to graphically present the data obtained from the target hardware . Each point on the chart represents a sample of collected data . We have already mentioned the possibility of putting different variables into separate charts , And you can also scale the data of specific variables to make the data more readable .

We can also easily zoom and move the graph with the mouse to see the required details ：

1. • adopt Left click One of the charts and drag it , We can move it .
   • adopt Right click One of the charts and drag , We drew an area that we wanted to look at more closely . This also changes the aspect ratio , If we have a very high density in one dimension .
   • We can also use the mouse wheel to zoom in and out . Rolling time , We zoom in / Reduce the current position of the mouse cursor . If data collection is not paused or stopped , Scrolling the mouse will only zoom in and out of time (x) Axis .
2. Scale： The way the data is displayed in the chart is determined by Scale factor And color assignment .Scale factor Enables us to display multiple variables with exponentially different values . Possible Scale yes 1e-9 To 1e+9 Between 10 Power and its negative value .
3. Format： Used to specify how data is displayed in the data table . For integer variables , The possible format is decimal 、 Hexadecimal and binary , And for floating-point variables , We can choose between regular format and scientific format .
4. Colors： Use the color selector dialog box that pops up by clicking the variable color button to select a color . From a group of 7 Assign a default color to each new variable in the predefined colors .

First click Data Acquisition Control Medium Start/Resume Button , And then click Application control Of Run Button , See the picture 2-3.

At this time in Chart and Data sheet in , Real time sampled variable values , See the picture 2-4.

notes ： Each variable can be assigned a separate chart display , See the picture 2-5.

3 How to export sampling data

The collected data can be exported to three different formats ：Excel、CSV Or a plain text file . This option is available in the menu File --> Export Data Find , See the picture 3-1,3-2,3-3.
