[求助] SIM800H库使用出现问题，麻烦进来看一下

本帖最后由 GG1101 于 2017-6-20 21:02 编辑

我前天在论坛上下载了SIM800H库文件，在使用使能来电显示例程的时候出现问题。用设定的号码手机打电话给SIM800H也打不通，后来我通过LCD1602打印 str 发现问题所在[mw_shl_code=c,true]#include <sim800cmd.h>

//initialize the library instance
//fundebug is an application callback function,when someon is calling.
Sim800Cmd sim800demo(fundebug1);

//phone number buffer
char str[15] = {'\0'};

//the setup routine runs once when you press reset:
void setup()
{
//initialize the digital pin as an output.

//initialize SIM800H,return 1 when initialize success.
while((sim800demo.sim800init()) == 0);
//enable SIM800H Modular Caller ID
sim800demo.DisplayPhoneNumber(OPEN);
}

//the loop routine runs over and over again forever:
void loop()
{


}
//application callback function
//Note that not too much to handle tasks in this function
void fundebug1(void)
{
  //get the phone number
  sim800demo.getCallnumber(str);

  if(memcmp(str,"18668603728",11) == 0)
  {
sim800demo.answerTelephone(); //answer
  }
  else
  {
sim800demo.cancelCall();//hangs up
  }

}[/mw_shl_code]

我用LCD1602打印出 str ,发现11位号码只显示了9位，前面的两位没有。根本不是11位完整的号码，而是668603728。出现这种情况不知怎么回事。
