Question

我有一个带有SD盾牌和GSM盾牌的Arduino超级巨星。我正在尝试从SD卡上的文本文件向200个号码发送一个短信，但每次我尝试发送超过100个号码时，Arduino都会重新启动。当我尝试发送到70个号码时，它不会崩溃。我一次只读一个号码，所以我不明白这个问题。我是Arduino编程的新手。

请帮助我这是一场锦标赛。这是代码：

#include <avr/pgmspace.h>
#include <SPI.h>
#include <SD.h>
#include <GSM.h>

#define PINNUMBER ""
GSM gsmAccess;
GSM_SMS sms;



// GSM
boolean notConnected;
//char input;
//byte input2;
//char txtContent[200];
byte i = 1;
byte f = 0;
boolean sendit;
//char senderNumber[11];
const String stopp PROGMEM = "Stopp";


//SD
char numbers[11];
//char nmbr;
int l = 0;

//Optimizing
const char q PROGMEM = '\xe5'; // å
const char w PROGMEM = '\xe4'; // ä
const char e PROGMEM = '\xf6'; // ö
const char r PROGMEM = '\xc5'; // Å
const char t PROGMEM = '\xc4'; // Ä
const char y PROGMEM = '\xd6'; // Ö

void setup() {
//  txtContent[0] = '\0';
  i = 0;
  pinMode(53, OUTPUT);
  Serial.begin(115200);
  //    Serial.begin(4800);
  Serial.println(F("Connecting to GSM..."));
  notConnected = true;
  while (notConnected) {
    if (gsmAccess.begin(PINNUMBER) == GSM_READY) {
      notConnected = false;
    }
    else {
      Serial.println(F("Not Connected"));
      delay(1000);
    }
  }
  Serial.println(F("GSM Ready"));
  if (!SD.begin(4)) {
    Serial.println(F("Error with SD card"));
    return;
  }
  Serial.println(F("SD Ready"));
  delay(1000);
  Serial.println(F("Write your sms and end it with * and press Send"));
  Serial.flush();
}

void loop() {
  char txtContent[300];
  if (Serial.available() > 0 && !sendit) {
    byte input2;
    input2 = (int)Serial.read();

      txtContent[i] = y;
    }
    i++;
    if (input2 == '*') {
      // Remove the * from text.
      for (int j = 0; j < sizeof(txtContent); j++) {
        if (txtContent[j] == '*') {
          txtContent[j] = '\0';

Arduino对我来说是一个奇怪的理由，但如果这有点像C，那么我冒险说sizeof(numbers)可能会返回44，因为你要求字节大小，这可能意味着你当numbers[43]长度为11时，for循环将迭代到numbers[]。请考虑改为：

for (int j = 0; j < sizeof(numbers)/sizeof(numbers[0]); j++) {

在此代码中检查数组大小的所有其他时间也是如此。另外，请仔细检查您的文本文件，以确保它以您预期的格式编写：11个数字，然后是逗号，没有例外。您可能应该尝试在点击逗号前确定f是否超过11位数，并在显示错误消息时“优雅地失败”。
