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.

FMS Bus/Truck/Trailer Toolkit

The Fleet Management System protocols (FMS and Bus-FMS  ISO 11992-1 ) are being used by a number of leading Bus and Truck manufacturers to provide interoperability of systems installed on heavy commercial vehicles and buses. They include a standard set of addresses and layouts for CAN messages used in these industries. The PCAN-FMS package, along with one of Peak’s wide range of CAN interfaces, will help you develop or debug your FMS application.

Used in the simplest way the FMS CAN bus is monitored by a PCAN interface, the FMS messages are decoded and their values displayed in a window, on the PC, as a  “Dashboard” with simple dials and indicators. If you want to you can then log all of the bus activity to a disk file. Alternatively you can take a previous log – input it to the FMS package and the result will be output to the CAN bus (and Dashboard) as well; allowing you to replay the events and use them as a source of stimuli  for testing an application.

The PCAN-FMS package can also create an FMS data stream by allowing the engineer to enter values via an easy to use graphics interface.

Choose one of three inputs.........        
Set sliders and status switches OR A CAN data stream OR A pre-recorded (and editable) file

Operator selects values with sliders


CAN USB data capture

  Input from a pre-recorded file

The Engineer may


Filter out selected Messages

Enable calculation of signals such as Fill level
  Simulate Errors   Inject selected Messages

Choose any or all output Options

To the PC’s Dashboard display   To a CAN interface to create a live CAN data stream   To a log file
Dashboard Display on PC as output   Output via a CAN Interface   Output to a log file
An ISO-7000 compliant display of Status Signal Names and Values        


FMS 01.00,  02.00 and Bus-FMS 00.01 and 00.02 are supported

For a PCAN-B10011S bus converter that links a high-speed CAN-node and a truck trailer CAN bus (ISO 11992-1) Specification follow this link.

Now with Version 2 of PCAN-FMS

Tour mode provides the ability to launch pre-selected projects from the Desktop to simplify automating standard runs as well as providing additional drive Data such as fuel consumption and average speed.
