sim800c+GPS芯片
一个练手的小设计，有点丑哈。附上程序和原理PcB图。

第一次发帖，做的不好烦请原谅哈

按键功能一个按键报警，蜂鸣器响，另外一个按键发送短信到指定的手机上，手机号码程序里面写好就行了

单片机源程序如下：

#include 'uart.h'

#include 'gps.h'

#include 'gsm.h'

#include 'lcd.h'

#define GPS_STR_LEN 48

//char xdata GPS_SEND_STR[GPS_STR_LEN];

sbit key = P1^3;

sbit key1 = P1^4;

sbit GPS_EN=P3^4;

sbit led1 = P3^3;

#define RMC_YES led1 = 0

#define RMC_NO led1 = 1

GPS_INFO GPS; //GPS信息结构体

bit GPS_rx_flag = 0;

bit GPS_Have_flag = 0;

#define SEND_NUMBER 'AT+CMGS='13420106297'rn'

char xdata send_data[37]='N: ',E: ',2000-00-00,00:00rn';

unsigned char send_len= 0;
