ST7 pCAN peripheral driver

Posted: 14 Sep 2009 ?? ?Print Version ?Bookmark and Share

Keywords:peripheral driver? ST7 CAN? controller area network?

The controller area network (CAN) norm defines a fast and robust serial bus protocol suited for local networking of intelligent devices such as MCUs, sensors and actuators. It is now widely used, mostly in the automotive domain, but also for home automation and industrial equipment control.

Several members of the ST7 MCU family have a built-in CAN peripheral named pCAN, which allows them to be used as nodes in a CAN network. A software driver provided is by ST to help you start designing and writing applications using the ST7 pCAN cell.

This application note aims to explain how to use the driver and how it works. Thus, you can either build your software from the provided files, or modify them to meet specific needs.

You will find in this application note:

? a brief description of the CAN protocol;
? an overview of the pCAN peripheral;
? the complete description of the user interface;
? the step-by-step development of an example application using the driver features;
? a technical report including a description of algorithms and internal data types.
