Real-Time Graph/Datalogger Demo for Embedded Webserver

This project is a proof-of-principle that an existing home medical device remote user interface that displays real-time analog signals in a chart recorder at 10 samples/second can be deployed over the Web. It involves developing a real-time scrolling chart display in a web page, which plots an analog signal being input into a Microchip microcontroller. In addition, the analog signal will be logged on the user's host in a basic ASCII file at 10Hz sampling rate. Using the Microchip [url removed, login to view] 2 demonstration board (we will supply) and the Microchip TCP/IP stack and demo webserver (all downloadable from their site and will be loaded and working out of the box)the assignment is to create one addditional web page which consists of an X-Y scrolling chart recorder-type graphical display of the potentiometer voltage input on the [url removed, login to view] board. The Microchip hardware and TCP/IP stack are well designed and stable, and their existing demo web pages already incorporate real time numerical display of the data via an AJAX script. The stack comes with support for basic form (GET,POST) functions, AJAX, the vendor's javascript library, and good implementation of basic protocols. There is little support and no room for server-side scripting, although it may be possible to modify the stack to support some additional query functions. Use of third-party chart code is fair game, depending on cost. We are open to a variety of approaches, as long as the chart scrolls smoothly without jitter or gaps and the log file works. All rights to be owned by us. Experience with embedded firmware (C), AJAX, Javascript, and dynamic data display in Web pages are key considerations.
