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.

BDM interface cable provides low-cost debugging for 68HCS12 processors


BDM Multilink

The new Multilink cable from Computer Solutions is an interface that provides low-cost access to the Background Debug Mode (BDM) on Freescale's 68HCS12 (also known as *12) as well as the earlier 68HC12 microcontrollers.

The 68HC12 and 68HCS12 are enhancements of the earlier 68HC11 with additional registers, more address space and an integral BDM interface. The 68HC12 runs at 16 MHz and the 68HCS12 (also known as STAR 12 or *12) at 25 MHz.

The Multilink cable will operate with the latest 25 MHz devices, and has speed to spare for the next generation of devices operating at up to 35 kHz internal frequency.

In addition to operating at 5 V, the interface will accept an external power supply, allowing it to operate with targets down to 2 V. It automatically adapts to the speed and voltage of the target.

The cable provides the hardware interface between an IBM PC parallel port and a standard 6-pin background mode header on a CPU12 target system. As a result, the developer can take advantage of the background debug mode to halt normal processor execution and control on-chip resources.

The interface allows the user to directly control the target's execution, read/write registers and memory contents, as well as carrying out programming of internal or external flash memory devices.

A wide range of PEmicro Products Windows-based software tools that use the Multilink cable is also available from Computer Solutions. The range includes a powerful in-circuit debugger, the WinIDE Integrated Development Environment (incorporating an optional configurable editor and assembler), a flash EEPROM programmer (capable of programming both on- and off-chip flash areas), and the REGXX program for simplifying the debugging of register I/O.

The combination of the Multilink cable interface and versatile debug packages running under Windows 95/98 or NT means that Computer Solutions can offer many of the features of a full in-circuit emulator for these new high-speed devices at a fraction of the price.
