Celebrating 37 years
supplying all your CAN and Embedded Development Tool needs


COMSOL has moved --  Please see the foot of the page for our new phone number and address

CAN FD interfaces now available


The latest enhancement to the CAN standard is CAN FD in which the data segment of the CAN message is transmitted at up to 10 times faster than the 1Mbit rate of CAN 2.0B. 

For details of CAN FD see our Updated Tutorial

Both single and double CAN channel USB FD interfaces are now available from Peak.   See our CAN FD page

Also at the Nuremberg exhibition Peak launched some new modules:  An intelligent RS232 module, a GPS module, a router in DIN rail format and a PCI/104-Express four Channel optoisolated  interface

A New 2015 version of their 120 page Catalogue of CAN interfaces, Modules and Software is available but be warned its a  27MBytes download

Latest News -- Cyclone for ARM supports more chips


Our low cost production FLASH programmer will now program the ATMEL SAMxxx, STM32,  NXP (M0, M3, M4), Freescale Kinetis (all), S32, TI-(Stellaris - LM3S, LM4F),  Infineon XMC4xxx,  Silicon Labs EFM32, SiM3, Cypress' PSoC® 4, Toshiba's TX00/TX03/TX04 as well as a wide range of SPI flash memories.

See Cyclone for ARM page


Embedded CPU debug support  ----  Kinetis special


This newsletter highlights Freescales Kinetis family of low cost Arm Cortex based microcontroller chips and the tool chains available to support development of code for them.  There are over 600 chips in the range whose smallest device is  a 32 pin package selling at < $1 yet it has 32KB of on chip flash.  P&E tools support a wide range of different development routes from the most popular commercial compilers to free GCC and GDB environments.  With Flash memory programmers available for low and high volume use also being available

On Chip Debugging Interface


This On-Chip-Debugging cable supports most Freescale chips and with suitable software can be used for Flash Programming and Debugging embedded target systems. It works with JTAG, SWD and BDM On-Chip-Debugging protocols.

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

It support these Freescale architectures:-   Kinetis  (JTAG and SWD),  ColdFire V1, +V1 and  V2 - 4 , Qorivva MPC5xxx, HC(S)12(X), S12Z, HCS08, RS08, 683xx/CPU32, HC16, DSC, MPC5xx/8xx and Power Architecture® PX series

And includes ribbon cables for all supported architecture

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

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

Generates programming voltage on RESET line for RS08 devices.

For more details.

Aside from supporting a wider range of chips a major attraction of the Universal FX is that for Synchronous architectures such as the Kinetis,  Qorivva,  Coldfire V2-V4, 683xx, HC16, Power Architecture PX Series and the DSC the communications can run at 4 to 10 times faster than the older Multilink interfaces.


ABATRON's BDI3000  now adds on-chip debugging support for the QorIQ™ T4240 (12 physical cores and 24 virtual cores) as well as the 64-bit single- and dual-core  P3041, P5010/20/21/40 communications processors from Freescale.

For the ARM CORTEX it supports........

-A8 such as the OMAP3430

-M3 such as the STM32 and Luminary Stellaris families

-M4 such as the Freescale Kinetis family

-As well as A5,A7,A8,A9,A15 M0, M3,M4 and R4

Now also supports the AppliedMicro's new X-Gene™ processor, the world’s first ARMv8 64-bit Server on a Chip Solution

CLICK Embedded Tutorials

Do you need to quickly become knowledgeable about a CPU family or Embedded USB, CAN or TCP/IP or On-Chip Debugging ?
If so we have prepared a series of short Technology Tasters to get you up to speed with the Micros, Standards and jargon.  We hope you will find them informative.

CLICK Supported Chips Directory

For each Microprocessor chip family (over 100 are listed) our Supported Chips Directory shows all the software and hardware available for developing applications for that family.


Price is always part of any engineering decision so we have always tried to publish prices along with our technical literature. Those items which are normally supplied from stock have their price held on our web shop - you can move back and forward to look at technical information without loosing the contents of your shopping basket. The prices shown on the web shop are for cash with order purchase within the UK for a wide range of products that are normally available for same/next day ship following day delivery or at worst on a 5 to 10 day turnaround and the web site prices do not include VAT (20%) or shipping.  Prices shown on the web site that are sourced from companies in the EU and US may regrettably be out of date given the fast moving exchange rate variations of the current economic climate - call for up to date prices.

 Prices for international purchases are essentially the same but additional costs must be covered and theUCC paperwork is more complex. Follow this link for details of  International Purchase conditions.  The Universal Currency Converter™ comes to you by kind permission of those nice people at Xenon Laboratories. It is supplied as a guide to exchange rates and neither Xenon nor Computer Solutions make any guarantees as to it's accuracy.

About us

Computer Solutions Ltd or COMSOL for short has been in business for over 35 years selling embedded development tools and working on consultancy projects. During this time our consultancy activities have ranged from designing true single chip applications to one system which has over 7,000 linked microprocessors (and that was before the days of the internet).

We like a technical challenge and many of the products described on this site have come onto our books as the result of responding to a clients need. So if you don’t see the answer to your embedded design problem on the site, drop us an email or give us a call and we will try to find you the tool you are looking for.
