stm32f407VET6 lwip httpd的例程

以下是一个基于STM32F407VET6的lwIP HTTP服务器的示例代码：

/* Includes ------------------------------------------------------------------*/
#include "stm32f4xx.h"
#include "lwip/init.h"
#include "lwip/netif.h"
#include "lwip/tcp.h"
#include "lwip/apps/httpd.h"

/* Private typedef -----------------------------------------------------------*/

/* Private functions ---------------------------------------------------------*/

/**
  * @brief  Initializes the lwIP stack and starts the HTTP server.
  * @param  None
  * @retval None
  */
void lwIP_HTTP_Server_Init(void)
{
  struct netif netif;
  
  /* Initialize the LwIP stack */
  lwip_init();
  
  /* IP address setting */
  IP4_ADDR(&netif.ip_addr, 192, 168, 0, 10);
  IP4_ADDR(&netif.netmask, 255, 255, 255, 0);
  IP4_ADDR(&netif.gw, 192, 168, 0, 1);

  /* Add the network interface */
  netif_add(&netif, &netif.ip_addr, &netif.netmask, &netif.gw, NULL, &ethernetif_init, &ethernet_input);
  netif_set_default(&netif);
  netif_set_up(&netif);

  /* Start the HTTP server */
  httpd_init();
  
  /* Infinite loop */
  while (1);
}

int main(void)
{
  /* Initialize the lwIP HTTP server */
  lwIP_HTTP_Server_Init();
  
  /* We should never get here as the HTTP server is running forever */
  while (1);
}

请注意，此示例依赖于lwIP库和STM32F4xx标准外设库。您需要根据您的开发环境和硬件配置进行适当的设置和调整。
