刚刚移植了一下uip的telnetd,还是比较简单方便的.

首先添加文件,注意usershell是自己写的.

在tcp.c中添加tcp端口监听程序

添加#include "telnetd.h"

void tcp_demo_appcall(void)
{	
	if(uip_conn->lport == HTONS(TCP_ClinetPort))
	{
		tcp_client_demo_appcall();
	}
	else if(uip_conn->lport == HTONS(80))
	{
		httpd_appcall(); 
	}
	else if(uip_conn->lport == HTONS(23))
	{
		telnetd_appcall();
	}
}

在主函数中初始化

telnetd_init();

usershell.c

//用户自定义shell
#include "shell.h"
#include "usershell.h"
#include <string.h>
#include "rtc.h"

char printfbuff[64];

//获取时间
void SHELL_GetTime(char *pStr)
{
	//RTC_Get();		//更新时间
	sprintf(printfbuff, "%02d:%02d:%02d\r\n",timer.hour, timer.min, timer.sec);
	shell_output("[获取时间成功]: ", printfbuff);
}

//获取日期
void SHELL_GetDate(char *pStr)
{
	//RTC_Get();		//更新时间
	sprintf(printfbuff, "%04d-%02d-%02d\r\n",timer.w_year, timer.w_month, timer.w_date);
	shell_output("[获取日期成功]: ", printfbuff);
}

usershell.h

#ifndef __USER_SHELL_H__
#define __USER_SHELL_H__




void SHELL_GetTime(char *pStr);	//获取时间
void SHELL_GetDate(char *pStr);	////获取日期


#endif /* __USER_SHELL_H__ */

修改telnetd.h

#ifndef __TELNETD_H__
#define __TELNETD_H__

#include "uipopt.h"

void telnetd_init(void);
void telnetd_appcall(void);

#ifndef TELNETD_CONF_LINELEN
#define TELNETD_CONF_LINELEN 40
#endif
#ifndef TELNETD_CONF_NUMLINES
#define TELNETD_CONF_NUMLINES 16
#endif

struct telnetd_state {
  char *lines[TELNETD_CONF_NUMLINES];
  char buf[TELNETD_CONF_LINELEN];
  char bufptr;
  u8_t numsent;
  u8_t state;
};

//typedef struct telnetd_state uip_tcp_appstate_t;

//#ifndef UIP_APPCALL
//#define UIP_APPCALL     telnetd_appcall
//#endif

#endif /* __TELNETD_H__ */

void telnetd_init(void);

static void
help(char *str)
{
  shell_output("Available commands:", "");
  shell_output("stats   - show network statistics", "");
  shell_output("conn    - show TCP connections", "");
  shell_output("help, ? - show help", "");
  shell_output("exit    - exit shell", "");
	shell_output("time?    - 获取当前系统时间", "");
	shell_output("date?,   - 获取当前系统日期", "");
}
/*---------------------------------------------------------------------------*/
static void
unknown(char *str)
{
  if(strlen(str) > 0) {
    shell_output("Unknown command: ", str);
  }
}
/*---------------------------------------------------------------------------*/
static struct ptentry parsetab[] =
  {{"stats", help},
   {"conn", help},
   {"help", help},
   {"exit", shell_quit},
   {"?", help},
	{"time?", SHELL_GetTime},
	{"date?", SHELL_GetDate},
	
   /* Default action */
   {NULL, unknown}};
/*---------------------------------------------------------------------------*/

shell_output("time?    - 获取当前系统时间", "");
shell_output("date?,   - 获取当前系统日期", "");

{"time?", SHELL_GetTime},
{"date?", SHELL_GetDate},
