示例代码说明

运行方法

配置工程

使用 Freemodbus 软件包示例代码，需要在 RT-Thread 的包管理器中选择它，并根据需要进行配置，具体路径如下：

RT-Thread online packages
    IoT - internet of things --->
        [*] FreeModbus: Modbus master and slave stack  --->
             [*]   Master mode  --->
                 [*]   Enable RTU master mode
                 [*]     Enable master sample
                 (1)       Test slave device address
                 (2)       uart number used by master sample, e.g. 2 means uart2
                 (115200)  uart baudrate used by master sample
             [*]   Slave mode  --->
                 [*]   Enable RTU slave mode
                 [ ]   Enable ASCII slave mode
                 [ ]   Use Contorl Pin
                 [*]   Enable slave sample
                 (1)     Slave device address
                 (2)     uart number used by slave sample, e.g. 2 means uart2
                 (115200) uart baudrate used by slave sample

添加示例代码到工程中，并编译下载之后，可以在控制台中看到这两个命令，分别是 Modbus 主机和从机的示例代码。要看代码运行的效果还需要 PC 端 Modbus Poll 和 Modbus slave 这两个软件的配合。
