Component Layout


The Amber Web Server is available in three configurations.  First time developers should consider purchasing the complete Hardware Development Kit (HDK) version which includes everything necessary to start development:  a programming adapter, a programmed web server board and a complete GNU C compiler with all the source code necessary to program a web server application on the board.   The board is also available pre-programmed with a sample application.  For OEM customers the board is available as an un-programmed blank.

Software Tools
A comprehensive set of development tools is available for applications development.  A Windows and Linux GNU C compiler provides high level application development.  An assembler/simulator is available from Atmel for assembly development and programming.  Extensive technical documentation and source code is available including detailed chip operation/management and application programs.

An open source OS, TCP/IP stack and web server code base with broad industry support is available for IP centric application development.  Many of the on chip peripherals are supported with drivers and application examples ensuring rapid application development.  The sector programmed Flash memory includes a small boot kernel for rapid IP based code download and support in multi-WS128 applications.

Hardware Development Kit (HDK)
The Hardware Development Kit (HDK) includes everything you need to start development.  Included is a CD with all necessary application software development tools, a parallel port ISP programming cable, wall mount power adapter and serial cable.  The HDK can be ordered with additional Expansion adapters for custom application development.

Expansion Options
The WS128 AVR Expansion Port connector contains most of the functional pins of the ATmega128 processor.  Several daughter cards are available for video IO, LCD display, general purpose IO,  and prototype  hardware development.
