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.

CAN Bus analyser and exerciser with data-logger,
control and display functions

CAN Bus Analyser

The new PCAN-Explorer CAN Bus analyser and exerciser from Computer Solutions is a flexible Windows program for showing what is happening on the CAN bus and for controlling and interacting with CAN systems.

The new software can be used for debugging the system or as a PC program driving it. PCAN-Explorer has a script language that makes it ideal for testing CAN units and for simple control and data acquisition. Its capabilities can be extended with predefined or user-produced add-ins.

The new software can be used in three ways: as a protocol analyser to decode and analyse all messages on the CAN Bus; as a data logger for recording and time-stamping data; and as a paperless recorder for displaying data in a strip-chart format.

The VB script language allows users to generate powerful test or operational sequences, and a 'control panel' panel plug-in allows the user to create a virtual instrument which can be controlled by an operator having no detailed knowledge of the CAN Bus parameters.

PCAN-Explorer shows all received messages in a list containing ID, length and decoded data. Each CAN message ID can be given a unique name ('speed', for example) which is then used in place of the ID when messages are logged, making complex systems easy to debug. The data is split, decoded by bit, byte or word files and then displayed in the appropriate base or scaled if it is a floating point to allow it to be easily interpreted.

The user may automate tasks in PCAN-Explorer by adding commands to perform these tasks, by adding toolbar buttons to control these commands, and by responding to CAN events.

Data-logger functions include flexible facilities to save logged data in text form compatible with EXCEL. The user has the option of logging all messages or a filtered subset, and up to four messages can be collected and their data displayed as a trace or strip-chart like display.

Predefined add-ins include CANdb Import, which enables openCANdb descriptions to be imported and exported, and Enhanced Plotter, which allows unlimited numbers of channels and Y axes to be displayed as well as offering much greater control of scales and layout. X- and Y-axis zooming is possible even while collecting data, and multiple cursors may be defined to allow complex relationships to be measured.

The User Panel add-in gives the user the ability to create a virtual instrument panel including LED-bit displays and pushbutton switches, a variety of meters and bar graphs with adjustable scales and maximum/minimum indicators, trend plots of CAN message signals, and slider and dial controls to set values. Using these features along with the VB Script language allows a complete CAN application to be controlled by an operator who need have no detailed knowledge of CAN.

PCAN-Explorer can be run on a laptop with a CAN interface for non-intrusive viewing of the events on the CAN bus. For a user developing a CAN application in C that is running on a PC, there is no need to buy a second CAN interface, Explorer will share the interface in order to test the application.

PCAN-Explorer is available for next day delivery from the Computer Solutions online web shop.
