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.
This page describes our Programmable CAN Controllers - we have a number of units that require the user to program the modules in C. This gives much more control and flexibility but requires a greater investment in time to program the unit. A GCC Compiler, GDB development environment and sample programs are supplied to cover the most basic functions and get you started.
It's a rather artificial separation but on the Peak Configurable Data Acquisition page we show systems that are configured via simple PC based Windows Applications. The advantage of this configuration process is that no programming expertise is required and configurations may be rapidly created and changed. They all need a PEAK-CAN interface for the initial loading of fresh configurations but after that can of course be read and written to by any valid CAN interface.
The PCAN-Router is a module that accesses two separate CAN networks. It uses a programmable ARM microcontroller to process the data it sees on these two channels , so that incoming CAN messages can be evaluated, converted, and filtered individually, in order to transmit appropriately customized CAN messages to the other network.
The PCAN-Router is shipped with demonstration firmware which performs one-to-one forwarding of the CAN messages between the two CAN networks at 500 kbit/s. The source code for this application is included on the CD-ROM supplied with the units. It is possible to load your own firmware onto the module via CAN by means of a pre installed boot loader.
The module is mounted in an aluminium casing, and is shipped in versions with two Sub-D connectors, or a screw-terminal strip. A power supply 7-26V DC is required.
The router can be fitted with an additional LIN channel if required.
Although designed as a Router these unit could ( within the limits of their single chip micros) be used as a network controller for simple systems
A version is available in a DIN Rail package see PCAN-Router DR which is user programmable
And a 4 channel version see PCAN-Router Pro which can be configured with a Windows app or can be user programmable
PCAN-RS-232 is a programmable module for
putting an RS-232 device (Printer or perhaps an old design of A/D
converter) onto a CAN network. The work of of formatting the data to
be sent to or taken from the CAN messages is done via a NXP LPC21
A GPS, compass, accelerometer, and gyroscope all
included in a single module that may be interrogated by the CAN bus.
It has a satellite receiver, a magnetic field sensor,
an accelerometer, and a gyroscope. The sampled data can be transmitted on
the CAN bus and logged on the internal memory card. The data processing is
performed by a NXP LPC4000 microcontroller.
The PCAN-GPRS Link is a development platform for telematic applications. An API allows simple integration of functions within a specific application environment. The PCAN-GPRS Link supports the evaluation of FMS and Bus FMS data (Fleet Management System) for which it produces consumption related vehicle data.
There are two programmable microcontrollers within the unit which process internal vehicle data and run the GPRS.
The DTCO info interface also allows the connection and processing of a
digital tacho with access to information such as driver identification and
driver working time. The GPS module can be used to determine location and
output the direction of travel.
