After supplying all your  Embedded Development Tool needs for 42 years
 Computer Solutions Ltd and its web shop are now closed.



 Having reached the grand old age of 75 it is time to relax and fulfil other ambitions.

 Its been an exciting ride with you, our customers, often on the bleeding edge of technology
 and I thank you for your friendship, your trust, and your orders.

Stay well        I wish you all success in your future projects.

Chris Stephens.



     But what to do with the web site ?  It has taken >12 man years of work to create a repository of knowledge on many aspects of the art and science of embedded microprocessor development and even after closing the shop it still gets over 4,000 visitors per month.  So as a service to my customers I have decide to keep it live providing my technical insights on the products and then redirecting viewers to sites where they can purchase the items they used to buy from us. Follow the link   "Home"

       The  "Information zone"  consists of articles produced as background tutorials on subjects of interest to those designing new products.  As different CPUs have became available this has lead to new development techniques and in particular to new ways of communicating between nodes.

Windows-based Wizard eases TCP/IP configuration for 8/16-bit microprocessors

CMX MicroNet Wizard

A Windows-based configuration Wizard which eases the setting up of TCP/IP parameters for use with 8- and 16-bit microprocessors is now available from Computer Solutions.

The new interface, which is integrated with the CMX-MicroNet high-level TCP/IP stack, allows the multiple options of a TCP/IP configuration to be easily set and the necessary initialisation code created.

CMX-MicroNet will work with virtually all 8- and 16-bit processors with minimal RAM and ROM requirements. The stack executes directly on the microcontroller, where support is available for dial-up or direct serial connection as well as Ethernet links. No proprietary protocols, intermediate gateways or special hardware are required to use it.

The system can operate in stand-alone mode or in conjunction with an RTOS. It provides support for multiple sockets, UDP, TCP, SLIP, Modem and IP. Options are available to support PPP, BOOTP, SMTP (post), DHCP (client), TFTP and FTP servers and HTTP web server.

CPUs currently supported include 8051, PIC18, M16C, C16X, AVR, eZ80, Z80/Z180, 78K0, 78K0S, H8/300H, H8S, 51-XA and V850. Source code is supplied, and no licence fee is required to create unlimited ROMs for a single application.

To support users wishing to develop TCP/IP applications in small embedded systems, Comsol has produced a free applications guide 'An introduction to TCP/IP for 8- and 16-bit embedded engineers', which is available from
