Online embedded web-server demo

Hi Wilfred, That's a very interesting approach. Are you actually embedding the C compiler on the device, or it is all precompiled? What is the footprint? What are the intended target platforms? Is this a new company? Is this product for sale yet? How much?

Z-World also has a new scripting language for rapid web interface development (for sale now for $149). It's called RabbitWeb. It runs on Z-World/Rabbit Semiconductor platforms. It operates on program variables and structures to eliminate complex CGI programming. Here's the hangman program source code and HTML ported to RabbitWeb:

The CSP and the C code generated by the CSP compiler is precompiled and embedded into the executable. Read the white papers.

Wilfred, enjoy!

Cool stuff (except for the $10,000 price tag - ouch!). I'd have to limit the RabbitWeb version to one player at a time because users change program variables. Does a single Coldfire board handle mutliple instances of the game for your demo or is there a bank of them?.

Well, yes, that should be obvious. How do you manage to mix up multiple instances of the game and the hardware? Maybe you need to read up on web-development. You can start of by reading this:
