After supplying all your Embedded Development
Tool needs for 42 years
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
Stay well I wish you all success in your future projects.
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.
NXP/Freescale have developed a chip family based on the 68HC08 range that uses newer technology - the HCS08 its faster and with a lower minimum voltage. A major enhancement for this new range is that it uses a true BDM interface rather than the MON08 monitor based debugger used on the 68HC08. The latest family of chips released are the RS08 (Reduced S08) this also uses the same BDM interface.
The USB Multilink Universal Interfaces
These 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 MCF55xx/56xx/57xx processor.
If you are unfamiliar with the use of "On-Chip-Debugging" we have a short tutorial
There are two models in the range - The Universal which is lower cost and the Universal - FX which provides significant performance improvements.
Both support the Cortex (see below † ) as well as the NXP/Freescale architectures
And have these Features
Target Frequency: 16Khz-50Mhz (applies to HCS08, RS08, ColdFire V1, 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
The USB Multilink Universal FX
As well as supporting all the architectures listed for the Universal, in addition, these are supported:-
683xx / CPU32, HC16, MPC5xx/8xx and Power Architecture® PX series
For Synchronous architectures such as the Cortex, 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 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
PEmicro Products support a wide range of HCS08 & RS08 Development options
NXP/Freescale CodeWarrior 10.6, Cosmic
-- Built in support for Multilink Universal & FX as well as Cyclone Universal LC and FX for both Debugging and Programming
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.
WinIDE is a windows package that includes a configurable text editor and provides the ability to launch a range of other programs from within its centralised operation. Includes the Assembler.
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.
Using the BDM cable to interface between a PC and a target processor this
windows software package will program either on chip or external
flash memory or on chip EEPROM.
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.
HCS08 & RS08 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.
To see which Flash devices PEmicro support follow this link .
Flash memory functions are :
These Windows packages include a command line driven application,
Cyclone Launch a batch control system and a set of DLLs providing a range of features of
value when using the Cyclone in production situations :-
Basic Edition ----- Free Download ---- Controls a single Cyclone from a PC via USB or Ethernet allowing one Programming Image to be held on the Cyclone which does not have to be downloaded every time so increasing performance.
Professional Edition ----- Controls up to 3 Cyclones from a PC via USB or Ethernet, allowing up to 8 Programming Images, which do not have to be downloaded every time, to be changed on the fly and dynamic data such as serial numbers to manipulated from the PC. Supported devices can be programmed in parallel, even if they are different devices with different data.
Enterprise Edition ----- As for the Pro version but unlimited numbers of Cyclones may be controlled from a single PC, More than 8 images can exist on the Cyclones and Licences for 5 end user PCs are included. Also provided is a full description of the RS232 and Ethernet command Protocols so that non Windows users can implement similar functionality.
