Ethernet Connectivity Board

Title: Ethernet Connectivity Option for Consumer Audio Product Programming: We are seeking assembly language programming for this application. The basic circuit design is not fixed yet, but will most likely be based on the 80C51 microprocessor with the ConnectOne ([url removed, login to view]) iChip for a hardware TCP/IP stack. There will be two user interfaces: 1) A web browser based interface with at least a setup page and an operation page. The setup page will allow setting the TCP/IP network properties (ie- Dynamic or Static IP, IP Address, IP Mask, etc.). The operation page will show the current status of each amplifier channel (Off, Active, Failure), the temperature of each amp channel, and the overall amplifier status (Off, Normal, Failure). There will also be 8 toggle buttons to turn each channel of the amplifier on or off. The telnet interface will use a simple ASCII character protocol (i.e. C1ON [turn channel one on with an ASCII carriage return command end character]) to control the amplifier functions or read back the current operational status (i.e. T1? [What is the temperature of amp channel one?]) Abstract: A circuit board assembly to provide a 10BaseT Ethernet network connection for remotely monitoring the operational status of a consumer audio product. This assembly will mount internally on the product and have analog input channels for temperature monitoring, digital inputs for status, and digital control outputs. The Ethernet port on the assembly must communicate to the external network via TCP/IP using both the http and telnet protocols. Conditions: The coder gives full source code and IP rights to the buyer. The coder reserves the right to reuse code in a non-competing industry (anything outside of the consumer audio or home automation industry)

## Deliverables

Complete and fully-functional working program(s) in executable form as well as complete source code (in assembly and/or C)of all work done. Complete copyrights to all work purchased.

## Platform

8051 microprocessor assembly language

## Deadline information

Code may not be reused by programmer for products used in consumer home audio or home automation. All other reuse is authorized.

Skills: Engineering, MySQL, PHP, Software Architecture, Software Testing, System Admin, Web Hosting, Website Management, Website Testing
