发送短信1的时间与Arduino的GPRS SIM900如果iput是HIGH [英] send SMS for 1 time with arduino GPRS SIM900 if an iput is HIGH
问题描述
我面对发送短信1如果输入为高一个问题，如果它是低==>没有SMS发送，如果低到高==>发送短信1。
这code不工作，只是发来的短信，当我打开GPRS，并没有什么发生了。
mclopez帮助我，谢谢你，但没有工作:(，这是新的code，我的延迟（）■写的，但同样的问题。
感谢您的帮助提前。

试着放慢对中断的时间间隔。这可能是由于在运行isr_timer（）主回路的可以如果语句EM>被锁定。我有一个鬼鬼祟祟的怀疑你正在尝试做的太过分了！
要小心试图以过高的频率来执行太复杂的中断，或CPU可能永远不会进入主循环，你的程序将锁定。 参考
话说，并检查您的主循环实际上是运行为什么不能在主
循环（）的底部添加一个简单的调试闪烁板载领导。INT onBoardLED = 13;无效设置（）
{
pinMode（onBoardLED，OUTPUT）; //和所有其余的
}无效循环（）
{
//做的东西 如果（onBoardLED == LOW）digitalWrite（ledPin，HIGH）;
其他digitalWrite（ledPin，LOW）;
}至少这样，你就会知道，如果主
循环（）甚至实际执行。
它是你与后告诉其猜测的没有别的办法通过，但真正获得一个单一的短信明明运行一次...如果一切看起来很好的尝试将周围的地方一些进一步的标志只是为了看什么得到执行，哪些不是。除此之外，建议我不能再发现什么，但有兴趣了解一下！祝您好运。

刚挖出这个环节我的书签。您可能会发现它很有用。结果
- 尼克金门 - 中断I faced a problem to send 1 SMS if an input is HIGH,and if it is LOW==> no SMS to send,if LOW to HIGH==> send 1 SMS. this code not working,just sent SMS when I turn the GPRS on,and after nothing is happened.
mclopez helped me,thank you,but not working :( , this is the new code that I wrote with the delay()s,but the same problem.
Thank you for helping in advance.

解决方案Try slowing down the interval on the interrupt. It is possible that due to several
ifstatements running underisr_timer()that the main loop may be locking up. I have a sneaking suspicion you are trying to do too much!Be careful about trying to execute too complicated of an interrupt at too high of a frequency, or the CPU may never enter the main loop and your program will 'lock up'. Reference
Saying that and to check that your main loop is actually running why not add a simple debug at the bottom of the main
loop()to flash the on board led..int onBoardLED = 13; void setup() { pinMode(onBoardLED, OUTPUT); // And all the rest } void loop() { // Doing stuff if (onBoardLED == LOW) digitalWrite(ledPin, HIGH); else digitalWrite(ledPin, LOW); }At least then you will know if the main
loop()is even actually executing. It obviously runs once as you are getting a single SMS through but really with no other way of telling its a guess after that...If all looks good try adding some further flags around the place just to see whats getting executed and what is not. Other than that suggestion i cant spot anything further but interested to find out! Best of luck
