User Interface - Tabs
The functionalities of the ROHM EVK GUI SW are divided between separate tabs.
1.4.1
Plotter – Tab
The Plotter in ( Figure 10 and Figure 11 ) shows device data from the current stream. The Plotter tool bar has its own Streaming and Raw data
buttons to enable quick changing between the two ( Figure 34 ).
Figure 34. Plotter tool bar
Toolbar has following functionality
•
Streaming: enables / disables data streaming
•
Data logging: enabled/disabled with the button with a red circle icon.
NOTE : When logging is enabled the red circle icon starts to blink.
•
Raw data: toggle stream data between counts and SI-units (1.4.1.1)
•
Auto scaling: plotter will auto scale the minimum and maximum values in the y-axis according to the device data.
•
Show grid
– enables data grid lines. The shortcut” G” can also be used for this.
NOTE : This may slow down the plotter’s performance.
•
Pause
– pauses the plotter. The shortcut “P” or left mouse button can also be used for this.
•
Clear
– clears all data points from the plotter. The shortcut “C” can also be used for this.
•
FFT
– turns on the Fast Fourier Transform (FFT) functionality of the plotter. More information can be found in ( 1.4.1.6. Frequency
analysis
).
•
Data range
– this slider bar adjusts the amount of data points shown in the plotter.
NOTE : At high data rates, the slider area of Data Range may flash red, indicating that it is unable to draw all the samples received. The data will
be averaged in order to fit into a screen.
The plotter tool bar has also dynamic buttons in the right corner. These dynamic buttons are created according to the device stream data channels.
By using these buttons, the user can show/hide data channels within the used device stream.
For example, for the KX132-1211 sensor, for all data streams that start with ADP (Advanced Data Path), there are two dynamic buttons - Advanced
Data Path and Accelerometer - that can be toggled to show / hide ADP and Raw Output Data streams respectively ( Figure 35 ).
