uip移植telnetd并添加自定义命令
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();
//自定义shell
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__ */
添加
void telnetd_init(void);
在shell.c中添加自定义命令支持
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}};
/*---------------------------------------------------------------------------*/添加命令显示
shell_output("time? - 获取当前系统时间", "");
shell_output("date?, - 获取当前系统日期", "");
命令列表
{"time?", SHELL_GetTime},
{"date?", SHELL_GetDate},
