更具lwip移植到stm32上实现以太网服务器

单片机源程序如下:

#include "led.h"
#include "lcd.h"
#include "key.h"
#include "stm32f4x7_eth.h"
#include "stm32f4x7_eth_bsp.h"
#include "netconf.h"
#include "tcp.h"
#include "udp.h"
#include "string.h"
#include "TCP_SERVER.h"
#define SYSTEMTICK_PERIOD_MS 10
/* Private macro -------------------------------------------------------------*/
/* Private variables ---------------------------------------------------------*/
__IO uint32_t LocalTime = 0; /* this variable is used to create a time reference incremented by 10ms */
uint32_t timingdelay;
int main(void)
{
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//设置系统中断优先级分组2
delay_init(); //初始化延时函数
LED_Init(); //初始化LED
//LCD_Init(); //初始化LCD
KEY_Init(); //初始化KEY
// BRUSH_COLOR=RED;
// LCD_DisplayString(10,10,24,"Illuminati STM32F4");
// LCD_DisplayString(10,40,16,"Author:Clever");
// LCD_DisplayString(20,70,24,"23 TCP_Server ");
//
// BRUSH_COLOR=BLUE;
// LCD_DisplayString(20,110,16,"IMT407G_IP:192.168.1.240"); //开发板作为服务器时的IP
// LCD_DisplayString(20,130,16,"TCP_Server_PORT:2040 "); //开发板作为服务器时的端口号
ETH_BSP_Config(); //DP83848相关IO初始化与ETH相关初始化
LwIP_Init(); //LWIP初始化
TCP_server_init(); //初始化开发板为服务器
while (1)
{
LwIP_Periodic_Handle(LocalTime); /* handle periodic timers for LwIP */
}
}
/**
* @brief Inserts a delay time.
* @param nCount: number of 10ms periods to wait for.
* @retval None
*/
void Delay(uint32_t nCount)
{
/* Capture the current local time */
timingdelay = LocalTime + nCount;
/* wait until the desired delay finish */
while(timingdelay > LocalTime)
{
}
}
/**
* @brief Updates the system local time
* @param None
* @retval None
*/
void Time_Update(void)
{
LocalTime += SYSTEMTICK_PERIOD_MS;
}
#ifdef USE_FULL_ASSERT
/**
* @brief Reports the name of the source file and the source line number
* where the assert_param error has occurred.
* @param file: pointer to the source file name
* @param line: assert_param error line source number
* @retval None
*/
void assert_failed(uint8_t* file, uint32_t line)
{
/* User can add his own implementation to report the file name and line number,
ex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */
/* Infinite loop */
while (1)
{}
}
#endif
