This application note introduces the basic concepts of Controller Area Network (CAN) and demonstrates how CAN bus communication is implemented using PSoC® 3 and PSoC 5LP.

简介

CAN (Controller Area Network) is a serial communication protocol developed by Robert Bosch GmbH in the early 1980s. This protocol was initially developed for automotive applications to communicate between subsystems without a central control. CAN is also being adopted in areas such as embedded systems (CANOpen) and factory automation (DeviceNet). CAN was standardized by ISO in 2003 (ISO 11898-1:2003).

This application note introduces the basic concepts of CAN protocol and demonstrates how CAN bus communication can be implemented using PSoC® 3 and PSoC 5LP (hereafter referred to as PSoC). Four code examples are included with this application note. Examples 1 and 2 together illustrate a simplex communication between two PSoCs. Examples 3 and 4 together demonstrate the Remote Transmission Request (RTR) feature of CAN.

The video talks about how to transmit and receive messages using CAN controller available in PSoC3.
