Computer Solutions Ltd

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.

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.

683xx, CPU32 development tools

The USB Multilink Universal FX

This greatly simplify the task of programming and debugging embedded target systems. They allow a PC to communicate with a target processor through a high-speed USB interface at the PC and a debug port at the micro. The PC can then control the microprocessor via the debug port of the target.

If you are unfamiliar with the use of "On-Chip-Debugging" we have a short tutorial

Both support the Cortex (see below † ) as well as the NXP/Freescale architectures

683xx / CPU32, HC16, Kinetis (JTAG and SWD), HCS08, RS08, HC(S)12(X), S12Z, ColdFire V1, +V1 and V2 - 4 , Qorivva MPC55xx/56xx/57xx, DSC, MPC5xx/8xx and Power Architecture® PX series. For latest list of chips see http://www.pemicro.com/cyclone/index.cfm#support and also as a wide range of on and off chip SPI and off chip flash memories.

And have these Features

Fast, hassle-free USB 2.0 communications interface

Draw their power directly from the USB port – no external power supply needed

Multi-voltage support for targets ranging from 1.6 to 5.25 Volts

Target Frequency: 16Khz-50Mhz (applies to HCS08, RS08, CFV1, S12Z, or HCS12X only)

Target Auto-frequency detection for HC(S)12(X,Z), HCS08 + trimming capabilities for HCS08 devices.

Generates programming voltage on RESET line for RS08 devices.

Includes ribbon cables for all supported architecture

For Synchronous architectures such as the 683xx, HC16, Cortex, Kinetis, Qorivva, Coldfire V2-V4, Power Architecture PX Series and the DSC the communications can run at 4 to 10 times faster than the Universal or the USB Multilink Universal or the older parallel Multilink interfaces.

Also it can provide 200 mA power to target MCU and it provides I/O line clamping for added protection

Development Software support

By adding the Flash Programming Software these units can program Flash memory and EEPROMs on the chip or attached to it. They are suitable for both development and small production runs

As these chips are no longer being actively developed by NXP/Freescale call COMSOL to discuss interfacing with any development software you may wish to use. PEmicro can provide...

Assembler

A simple command line assembler adequate for many small applications ( no linker but the source file can have multiple includes). It provides macros and conditional assembly.

In Circuit Debugger

A windows package that via the cable provides all the services of a debugger providing as it does access to the contents of variables and registers along with control of the CPU's execution via Breakpoints and Run commands.

Unit programs

A set of C library calls that provide an API for using the BDM interface. Ideal for those who need to write their own PC based test or diagnostics programs. The standard version includes a license for 5 units. The distribution version provides unlimited production of applications.

68K Flash Programming Software

An interactive flash programming software package that allows you to program/reprogram both internal and external flash devices in-circuit, via a PEmicro interface cable. Perfect for development, production line programming, or field firmware upgrades. PEmicros products contains our entire library of setup files for this processor, and includes both interactive and command-line versions for use in development and production.
