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
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(); }
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! */ void GPIO_Configuration(void) { GPIO_InitTypeDef GPIO_InitStructure; /* Enable GPIOs clocks */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB | RCC_APB2Periph_GPIOC | RCC_APB2Periph_GPIOD| RCC_APB2Periph_AFIO , ENABLE); /* ETHERNET pins configuration */ /* AF Output Push Pull: - ETH_MII_MDIO / ETH_RMII_MDIO: PA2 - ETH_MII_MDC / ETH_RMII_MDC: PC1 - ETH_MII_TXD2: PC2 - ETH_MII_TX_EN / ETH_RMII_TX_EN: PB11 - ETH_MII_TXD0 / ETH_RMII_TXD0: PB12 - ETH_MII_TXD1 / ETH_RMII_TXD1: PB13 - ETH_MII_PPS_OUT / ETH_RMII_PPS_OUT: PB5 - ETH_MII_TXD3: PB8 */ /* Configure PA2 as alternate function push-pull */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_Init(GPIOA, &GPIO_InitStructure); /* Configure PC1, PC2 and PC3 as alternate function push-pull */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1 | GPIO_Pin_2; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1 ; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_Init(GPIOC, &GPIO_InitStructure); /* Configure PB5, PB8, PB11, PB12 and PB13 as alternate function push-pull */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_8 | GPIO_Pin_11 | GPIO_Pin_12 | GPIO_Pin_13; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_11 | GPIO_Pin_12 | GPIO_Pin_13; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_Init(GPIOB, &GPIO_InitStructure); /**************************************************************/ /* For Remapped Ethernet pins */ /*************************************************************/ /* Input (Reset Value): - ETH_MII_CRS CRS: PA0 - ETH_MII_RX_CLK / ETH_RMII_REF_CLK: PA1 - ETH_MII_COL: PA3 - ETH_MII_RX_DV / ETH_RMII_CRS_DV: PD8 - ETH_MII_TX_CLK: PC3 - ETH_MII_RXD0 / ETH_RMII_RXD0: PD9 - ETH_MII_RXD1 / ETH_RMII_RXD1: PD10 - ETH_MII_RXD2: PD11 - ETH_MII_RXD3: PD12 - ETH_MII_RX_ER: PB10 */ /* ETHERNET pins remapp in STM3210C-EVAL board: RX_DV and RxD[3:0] */ GPIO_PinRemapConfig(GPIO_Remap_ETH, ENABLE); /* Configure PA0, PA1 and PA3 as input */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_3; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; GPIO_Init(GPIOA, &GPIO_InitStructure); // /* Configure PB10 as input */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10; // GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; // GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; // GPIO_Init(GPIOB, &GPIO_InitStructure); // /* Configure PC3 as input */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_3; // GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; // GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; // GPIO_Init(GPIOC, &GPIO_InitStructure); /* Configure PD8, PD9, PD10, PD11 and PD12 as input */ // GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10 | GPIO_Pin_11 | GPIO_Pin_12; GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9 | GPIO_Pin_10; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING; GPIO_Init(GPIOD, &GPIO_InitStructure); /**/ /* MCO pin configuration------------------------------------------------- */ /* Configure MCO (PA8) as alternate function push-pull */ /*需要STM32F107给DM9161提供 50MHZ 的 时钟*/ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_Init(GPIOA, &GPIO_InitStructure); }
第三个函数:void Ethernet_Configuration(void); 注意要使用这个函数 要进行宏定义两个参数!
//因为选择 RMII 接口 (不懂的请百度)
#define RMII_MODE /* RMII mode for STM32107VC TO DM9161,2016年10月21日17:27:32 */
/* DM9161的物理地址是通过接收的4个脚26到29(与RXD3—RXD0复用)以及35脚CRS/PHYAD4来确定的。
* 具体来说,就是在上电复位的时候,根据这几个脚的高电平来确定地址。
* 比如我手头的板子上采用的RMMI,只接了RXD0,RXD1,其他几个脚空着,所以上电时只有RXD0与RXD1是高电平,
* 因此DM9161物理地址为3.

中断配置 和中断服务函数配置。

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
