標題: 之前寫了一個智能家居下gsm模塊的程序
之前寫了一個智能家居下gsm模塊的程序，可以根據(jù)按鍵輸入的密碼來判斷是否可以進行修改報警號碼，并向對應的手機號碼發(fā)送報警信息，不過得注意需要插入sim卡。程序附錄如下：
#include "gsm.h"
#include "common.h"
#include "serial.h"
#include "string.h"
#include "delay.h"
#include <stdio.h>
#include <stdlib.h>
#include "key.h"
#include "24c02.h"
#include "lcd1602.h"

#if 0
/* 發(fā)送AT指令 */
int gsm_send_command(uchar *command, uchar *response, uchar waittime)
{
int xdata res = 0;
uart_send_str(command);
if(response && waittime) //需要等待應答
{
while(--waittime) //等待倒計時
{
delay_ms(10);
if(RI)//接收到期待的應答結果
{
if(is_gsm_get_response(response)) break;//得到有效數(shù)據(jù)
RI = 0;
}
}
if(waittime == 0) res = 1;
}
return res;
}

/*
*是否得到想要的回應
* return 0 : 響應正確
* return -1:  沒得到正確的響應
*/
uchar* is_gsm_get_response(uchar *response)
{

uchar xdata resp[20];
uchar *strx = 0;
int xdata len = 0;
int xdata i;
uart_receive_str(resp); //讀取響應
strx = strstr((const char*)resp, (const char*)response);
return strx;

}

int gsm_send_sms(uchar *phone_number, uchar *sms_message)
{
const uchar xdata message[] = "Someone in your home,please check.";
int xdata res;
char xdata *p1;
p1 = malloc(sizeof(char)*4);

res = gsm_send_command("AT+CMGF=1\r\n", "OK",200); //設置文本模式

res =gsm_send_command("AT+CSCS=\"GSM\"\r\n","OK",200); //設置TE字符集為GSM

res = gsm_send_command( "AT+CSMP=17,0,2,25\r\n", "OK",200); //設置短消息文本模式參數(shù)

res = gsm_send_command("AT+CMGS=\"18819467282\"\r\n", ">", 300);
delay_ms(10);
uart_send_str(message);
delay_ms(10);

sprintf(p1,"%c",0x1a);
return 0;
}
#endif

void gsm_call(void)
{
   uchar phone_num[12];
   uchar all[24] = "ATD";
   uchar one[] = ";\r\n";
   iic_read_password_phone(phone_num, 1); //讀出電話號碼
   strcat(all, phone_num);
   strcat(all, one);
   uart_send_str(all);
}

void change_phone_number(uchar *password)
{
uchar xdata pass_set_suceess[16] = "phone number set";
uchar xdata new_phone[16] = "New phone number";
uint i;
int flag = -1;

if(check_password(password, 0, 1) == 0) //密碼正確
{
   flag = password_display(password, new_phone, 16);
   if(flag == 0)
   {
   iic_write_password_phone(password, 1);    //寫入新號碼
   delay_ms(10);

   lcd1602_init(0x0c);
   write_1602com(FIRST_LINE);
   for(i = 0; i < 16; i++)
   write_1602dat(pass_set_suceess[i]);
   delay_ms(2000);
   lcd1602_init(0x0c);
   }
   else
   lcd1602_init(0x0c);
}
}
