2.2. CANOPEN_SLAVE

2.2.1. 概述

canopen_slave_demo 例程提供如下功能：

• HeartBeat 心跳测试

• NMT 测试

• SDO 测试

• PDO 测试

2.2.2. 硬件设置

一块开发板下载 master 例程, 一块开发板下载 slave 例程, 连接两块开发板

2.2.3. 运行步骤

程序下载成功后, 会主动上发 pre-optional 信息, 等待主栈下发指令

2.2.4. 运行现象

当该例程成功运行后，会在串口终端打印如下:

2.2.4.1. 测试

The current routine is a canopen slave role. The board runs the current routine and connects to the board running the master role.

Slave 端打印如下所示：

rxSize = 11, txSize = 8
excessive number of concurrent CAN RX filters enabled (needs 11, 16 available)
enter slave mode ~ ~

Slave 端不会有特殊打印, 判断测试结果以 master 端打印为准。
