在图片中,当我放置线条时,相同的代码似乎不起作用
if (gsm.begin(9600)) //Start the GSM COM
{
(sms.SendSMS("+8613668914901","Your Home Security system is being bridged"));
但是这条线在void设置功能中很有用.
我该如何解决这个问题?在void设置中,草图工作正常,但是当我也将代码放在函数CheckPassword中时,它不会发送SMS.
我也尝试创建一个函数让我们说出无效的SMS并在checkPassword函数中调用它但它没有解决问题,在void设置中调用同样的函数工作正常.
最佳答案 您应该在setup函数中仅初始化gsm一次.
在您的代码中,您尝试在checkPassword方法中再次初始化它,这显然不会起作用.
因此,您应该从checkPassword函数中删除行gsm.begin(9600).
更新1:
在您的方案中,您为键盘保留引脚9,8,7,6,5,4,3,2.但是,同时为GSM模块保留引脚2,3(参见GSM.cpp):
#define _GSM_TXPIN_ 2
#define _GSM_RXPIN_ 3
为了多种目的而使用相同的引脚通常会导致(如果没有正确完成)未定义的行为,在最佳情况下,这意味着您的草图没有按预期执行,并且在最坏的情况下,它可能会损坏您的组件.
您已经在串行库中使用引脚0,1,但根据您的代码,如果您想将现有引脚重新定位到组件,则引脚10,11,13仍然应该是空闲的.
另请注意GSM库中的以下警告:
[3] My shield doesn’t work. Why?
Check this steps and then ask for support on the issues’ page on google
code.1) SIM900 and SIM908 require about 1 A during the hardest tasks.
You should have an external power source that can provide about
1 A at 8-12 V2) If the SIM90X blinks (1 Hz) for some seconds and then turn off,
probably it’s a communication’s problem. Check the switch/jumpers
for Serial communication.3) Arduino Uno has 2 KB of RAM. Library takes about 80% (we are working
to reduce it), if you use more than 20% left, Arduino can restart
or print on serial strange strings.4) Check the jumper of communication, power source (battery or externel) and charge.
