Introduces the ST7 MCU series with pCAN peripheral devices and provides drivers and usage methods
This document is an application note for the ST7 pCAN peripheral driver, designed to assist developers in using the built-in CAN peripheral of ST7 microcontrollers. It provides a comprehensive guide on how to utilize the provided software driver to design and write applications for CAN networks.
The note covers the CAN communication protocol, including its characteristics, frame types, and physical representation. It details the user interface of the driver, explains how to implement notification functions, and includes a step-by-step development of a demo application. Additionally, it offers a technical report on the algorithms and internal data types used within the driver.
The protocol allows baud rates up to 1Mbaud for networks of up to 40m.
The document states that 50kbaud is used for networks up to 1km long.
The data field in a CAN Data Frame can contain up to 8 bytes.
