- * This module defines the interface for the application. It contains
- * the basic functions and types required to use the Modbus protocol stack.
- * A typical application will want to call eMBInit() first. If the device
- * is ready to answer network requests it must then call eMBEnable() to activate
- * the protocol stack. In the main loop the function eMBPoll() must be called
- * periodically. The time interval between pooling depends on the configured
- * Modbus timeout. If an RTOS is available a separate task should be created
- * and the task should always call the function eMBPoll().
- *
- * \code
- * // Initialize protocol stack in RTU mode for a slave with address 10 = 0x0A
- * eMBInit( MB_RTU, 0x0A, 38400, MB_PAR_EVEN );
- * // Enable the Modbus Protocol Stack.

-# 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。
-
-![1561348568591](figures/run.png)
-
-### 运行主机示例
-
-首先下载安装和主机示例代码配合的 Modbus slave 软件。
-
-然后，在命令行输入 `mb_master_sample` 命令就可以运行主机的示例代码。
-
-运行之后，打开 Modbus slave 软件，点击菜单“Setup”中“Slave Definition.. F2”进行参数设置。
-
-![img](figures/slave_cfg.png)
-
-点击菜单“Connection”中“Connect.. F3”进行连接。弹出连接对话框，根据具体情况配置：
-
-![1561351899477](figures/slave_con.png)
-
-连接成功，可以看到寄存器列表中的第 2、3个寄存器的数值在不断变化。
-
-![1561352048209](figures/slave_run.png)
-
-### 运行从机示例
-
-从机的运行示例和主机相差不大，只是 PC 端配合调试的软件，换成 Modbus Poll 即可。不再赘述。
