Designing The Next Step In Internet Appliances

Web-Enabled Information Appliances Are Showing Up In Many Places, But The Challenge Is Supplying Web Pages with Dynamic Content.

Date Posted: March 23, 1998 12:00 AM

By utilizing a conversion tool the process for incorporating web content into an embedded device is reduced to the following set of steps.

  1. Generate web content using an HTML editor of choice. For dynamic content pages, proprietary tags are inserted where the dynamic portions are to appear.
  2. Use a conversion tool to convert the HTML pages, images, and applets into embedded application source code.
  3. Implement the generated shell routines that are specific to the overall application running in the embedded device.
  4. Compile and link the resulting source code.

The embedded device can now serve web content that is static and dynamic. In addition, the embedded device also can process forms data returned in response to end user submissions.

The following example illustrates the first three steps in the above process for Osicom's NET+ARM product (see "A Code Example,"). Along with firmware to support an e-mail and FTP server, it comes bundled with an embedded HTTP server, and an application programming interface (API) into the HTTP server. This is a conversion tool that converts HTML pages, images and applets into source code. The basic techniques however, may be easily adapted to the development of any platform with similar capabilities.
