　  ANDROID  CHART VIEWER

 ---> Show in Japanese ( 日本語で表示 )


ChartViewer (Android Application）

 This software is an ANDROID terminal application that displays data charts in real time.
Receives data from various devices and personal computers and displays the waveform.
Each connected device or personal computer must have a function to transmit data such as sensor output.
Various devices can be connected via serial line (RS-232C / UART) and WiFi (socket (TCP / IP)).
The numerical value is extracted from the received data, and a chart (waveform graph) is displayed in real time like an oscilloscope.


Functional overview

１．Connection

 　Connects to various embedded devices via USB-SErial / WiFi.


２．Menu



３．Filter the waveform display

Check boxes at the bottom right of the screen allow you to select the data items to be displayed on the screen.
(In the following example, the red waveform is hidden by turning off the red check box.)



　You can also show / hide the checkbox itself by tapping the button to the right of the checkbox.

４．Range setting by drag operation (enlarged display of waveform)

 By dragging the screen vertically, the dragged area can be enlarged and displayed.
At this time, the range you dragged is set as the range, and the automatic-range mode is canceled.
Tapping the screen will (again) enter autorange-range-mode.



５．Parameter setting for USB-Serial (RS-232C / UART)
　The figure below shows the screen for setting the communication speed using the "Baud Rate" spinner.
