	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.	R4
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.

A copy of this software package is included free of charge with all the PEAK CAN interfaces.  It includes:

• PCAN-VIEW - CAN bus diagnostic package
• Free  Device Drivers and APIs

• Support for a number of CAN Protocols

• Linux drivers
   

PCAN-VIEW

This windows package provides basic diagnostics and allows the user to view messages on the CAN bus and to create CAN messages.  It runs under Windows Vista/ 7/8.1  (32/64-bit).

The transmission rate and ID length are configurable and a filter can restrict the range of message IDs displayed to simplify analysis of large systems.

The most recent data for each message ID is displayed along with the time since last message, count of number of instances, time since last RTR and count of RTR instances. Message IDs can be displayed in Hex or decimal,  data is displayed in Hex, decimal or ASCII and errors such as over-run and baud rate problems are reported.

 

CAN FD is supported and for those interfaces that support it (see interface spec) bus load is also displayed

 

Messages can be sent using the Transmit section as one-shot, repeating periodically or in response to a remote request (RTR).

 

         A trace mode allows the operator to record and save CAN Traffic for later analysis.

   See a Video of the trace in action

 

PCAN-Basic code API

 

Drivers are provided for Windows Vista/7/8.1/CE (ARM & x86) and Linux (all for 32/64-bit). For DOS and older Windows versions call/email with your needs.

They provide a simple interface, that is common to all our PEAK CAN modules, and that is capable of driving up to 8 separate CAN channels. Either simple linear Read/Write commands may be used or the application can be multi-threaded and the appropriate thread started when a specific CAN event occurs. Timing information on CAN messages is available.

Example programmes are provided in C++, C#, C++/CLR, Delphi, VB.NET, Java or Python 2.6.

The API is simple to use: -

	CAN_Initialize	Initialisation of the channel, setting the speed, linking port and interrupt for non PnP devices
	CAN_Write	Sending a CAN message (11/29 BIT ID and RTR are possible)
	CAN_Read	Reading a CAN message
But support is available for more sophisticated ways of working
	CAN_SetValue	Turns on and off .....filtering, Event management, message and DLL entry logging
	CAN_GetValue	Reads back that data
	CAN_FilterMessages	Configures a filter for that channel
	CAN_Uninitialize	Disconnect from channel
	CAN_Reset	Reset a channel
	CAN_GetStatus	Reading the bus status information

 

A useful feature of this package is that it is possible to monitor and interact with an application using these functions from a copy of PCAN-VIEW or PCAN-Explorer running on the same PC without requiring a second CAN interface.

 

Additional CAN Protocols

 

The PCAN-CCP API is a programming interface for the communication between Windows applications (Masters) and electronic control units (Slave ECUs). The API is based on the CAN Calibration Protocol (CCP) by ASAM and is mainly deployed for development in the automotive area.

The Extended Calibration Protocol (XCP) is a further development of CCP, but not compatible with it. XCP supports multiple transmission mediums. The corresponding programming interface by PEAK-System is called PCAN-XCP API which uses the CAN bus as transmission medium analogous to the PCAN-CCP API.

PCAN-ISO-TP API (ISO 15765-2),   PCAN-UDS API (ISO 14229-1)   and the PCAN-OBD-2 API (ISO 15765-4) are all supported.

These all utilize the PCAN-Basic programming interface to access the CAN hardware in the computer and are free of charge.

 

Linux support for Socket CAN is also available.        https://www.peak-system.com/fileadmin/media/linux/index.htm
