CAN Stack Example 2 for UC3C-EK Documentation

Introduction

This documents data structures, functions, variables, defines, enums, and typedefs in the software for the CAN driver.

The given example is a CAN driver example using two CAN channels available. A mailbox is defined by the user and all messages are sent easily.

Compilation Info

This software was written for the GNU GCC for AVR32 and IAR Systems compiler for AVR32. Other compilers may or may not work.

Main Files

• canif.c: CAN low level driver.
• canif.h: CAN low level header file.
• can.c: CAN High level driver.
• can.h: CAN High level header file.
• conf_can.h: Configuration file for the CAN Lib.
• can_example2.c: CAN Driver example.
• conf_can_example.h: Configuration file for the CAN example.

Configuration Information

This example has been tested with the following configuration:

• UC3C_EK evaluation kit;
• CPU clock: 16 MHz; This example demonstrates that how to send/receive messages from the CAN.
• Plug a DB9 cable on CAN1 DB9 connector and an external CAN node to setup a 'point to point' network.
• Configure the baudrate to 1Mbps.
• Start the example.
• A menu is displayed – 1) If choose 1), the UC3C_EK will send a message on CAN node. In case the message is correctly sent, a message is displayed. – 2) If choose 2), the UC3C_EK will receive a message on CAN node. In case the message is correctly received, a message is displayed with the content of the FRAME. – 3) If choose 3), the UC3C_EK will send a remote message on CAN node. In case the message is correctly sent, a message is displayed.
• The CPU is in sleep mode (STATIC) at the beginning of the application and then is waked up after the reception of the message from the external CAN node
