  • DM9161 和 STM32F107 和 FreeRTOS 和 LWIP

    1、首先移植 FreeRTOS到  107上 可以正常运行。

       可以到群下载移植好的,文件名称:STM32F107VC+FreeRTOS V8.2.3+kfifo(巧夺天工)!

    2、第二步 :ST 官方 下载 STM32F107  的 官方 DEMO (STM32F107xx互联型微控制器上的lwIP TCP/IP协议栈演示

      链接1: http://www.stmcu.org/document/detail/index/id-213140

      链接2:http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-libraries-expansions/stsw-stm32026.html

    3、第三步:复制官方DEMO 文件目录(C:UsersadminDesktopSTM32F107_ETH_LwIP_V1.0.0Libraries)下的 STM32_ETH_Driver 文件到 你的 工程路径下,并添加到工程中。

      我复制到 了 这个 路径。

       添加到工程中:

    第四步:新建 stm32f107_eth.c 文件 ,主要存放 STM32F107 和 DM9161 的 GPIO、DMA、MAC 的 寄存器 配置函数,下面代码分析:

          (注意:以下几个函数都是在官方demo中 stm32f107.c 中 复制 和 稍作修改而来)

        

      注意 在stm32f107_eth.c 文件 中 包含头文件:

        #include "stm32_eth.h"

      第一个函数:void stm32f107_eth_init(void);(直接在 main.c中调用)。

    /**
      * @brief  Configures the Ethernet Interface
      * @param  None
      * @retval None
      */
    void stm32f107_eth_init(void)
    {
        
        GPIO_Configuration();
        
        Ethernet_Configuration();
    
    }
    View Code

      

    第二个函数:void GPIO_Configuration(void);        (STM32F107 和 DM9161 之间的接口是 RMII 接口,所以只配置 RMII接口所用到的引脚和时钟)。

    /**
      * @brief  Configures the different GPIO ports.
      * @param  None
      * @retval None
        * 修改记录:因为选择的是ETH_RMII 接口,因此 屏蔽掉不必要的接口,这样,就不会引起其他引脚的问题!

    第五步:移植LWIP协议

      1、首先下载 lwip 源码,2016年10月22日17:44:25 最新源码的版本是:lwip-2.0.0.RC2.zip

      下载地址:

          http://download.savannah.gnu.org/releases/lwip/

      2、下载ST官网 关于FreeRTOS和LWIP 在STM32F4X7上跑的 DEMO
