5.2.2 Web Demonstration
Use the sample Web files located in the “IODemo” folder in HelloDevice utility software for digital I/O control
on the Web. (Refer to the file location in the Figure 5.1) Web files used for the digital I/O demo are “index.html”,
“io.jar” and “404.html”. This example demonstrates control of the demo board I/O with the HelloDevice
connected to the Web
(1) Modify the IP address in the “index.html” file in the “IODemo” folder. Input the current HelloDevice IP
address to the IP address parameter related to the Java applet in the “index.html” file. Leave other parameter
unchanged and save the file.
Figure 5.10. Modifying the “index.html” file for digital I/O control
Note!
Several parameters can be used for Java applet I/O communication.
- IP address: HelloDevice IP address
- TCP port: Always set as 6001
- Polling interval: 100 ms resolution, Set proper value according to the application
e.g. “polling value =1” means that I/O status will be polled at every 10 ms.
(2) Build and upload the Web files in the “IODemo” folder. Upload the Web page to the HelloDevice by
following the steps described in the Chapter 5.1. Select the “IODemo” folder that contains the Web files, instead
of the “FirstDemo” folder.
