我正在尝试使用arduino yun将机器生成的零件数量输出到谷歌电子表格。通过我的设置，我可以暂时将数据输出到电子表格。然而，过了一段时间，云停止工作。我已经指示代码正在运行的红色LED指示灯熄灭，我无法再在端口列表中看到arduino。 32u4芯片的复位会导致LED重新亮起，表示代码正在运行，但电路板仍然没有出现在端口菜单中。
我在我们的工作室进行了测试，它已经运行了7-12个小时，没有任何问题。只有当我们把它带到生产车间时，我们才开始遇到这些问题。有谁知道问题可能是什么？以下是代码中最相关的部分：
#include <elapsedMillis.h>
#include <Process.h>
#include <Bridge.h>
#include "TimeLib.h"
// On Arduino: 0 - 1023 maps to 0 - 5 voltsf
#define VOLTAGE_MAX 5.0
#define VOLTAGE_MAXCOUNTS 1023.0
unsigned int buttonCount = 0;
float voltage = 0;
elapsedMillis timeSinceLastCycle = 0;
elapsedMillis transmitData = 0;
int pressFlag = 0;
Process date;
int hours, minutes, seconds;
int lastSecond = -1;
Process sendData;
String printDate() {
// String currTime = String(hours) + ":" + String(minutes) + ":" + String(seconds);
if (lastSecond != seconds) { // if a second has passed
// print the time:
if (hours <= 9) {
Console.print("0"); // adjust for 0-9
}
Console.print(hours);
Console.print(":");
if (minutes <= 9) {
Console.print("0"); // adjust for 0-9
}
Console.print(minutes);
Console.print(":");
if (seconds <= 9) {
Console.print("0"); // adjust for 0-9
}
Console.println(seconds);
// restart the date process:
if (!date.running()) {
date.begin("date");
date.addParameter("+%T");
date.run();
}
}
//if there's a result from the date process, parse it:
while (date.available() > 0) {
// get the result of the date process (should be hh:mm:ss):
String timeString = date.readString();
// find the colons:
int firstColon = timeString.indexOf(":");
int secondColon = timeString.lastIndexOf(":");
// get the substrings for hour, minute second:
String hourString = timeString.substring(0, firstColon);
String minString = timeString.substring(firstColon + 1, secondColon);
String secString = timeString.substring(secondColon + 1);
// convert to ints,saving the previous second:
hours = hourString.toInt();
minutes = minString.toInt();
lastSecond = seconds; // save to do a time comparison
seconds = secString.toInt();
String currTime = hourString + ":" + minString + ":" + String(seconds);
return currTime;
}
}
void checkVoltage() {
int sensorValue = analogRead(A0);
voltage = sensorValue * (VOLTAGE_MAX / VOLTAGE_MAXCOUNTS);
Console.println(voltage);
delay(50);
if (voltage >= 4.9 && pressFlag == 0) {
Console.println("Delaying");

unsigned long int intCycleTime = timeSinceLastCycle;
timeSinceLastCycle = 0;
digitalWrite(LED_BUILTIN, LOW); // turn the LED on (HIGH is the voltage level)
printDate();
String pressTime = printDate();
Console.print("PressTime is ");
Console.println(pressTime);
buttonCount++;
Console.println(buttonCount);
pressFlag = 1;
String part1 = "curl -X POST -H \"Content-Type: application/json\" -d '{\"value1\":\"";
String timeString = pressTime;
Console.print(timeString + " seconds");
String part2 = "\",\"value2\":\"";
String numParts = String(buttonCount);

/*while(sendData.running()){

}
} */
Console.print("Data Available: "); // A value of 32 indicates a successful transmission of data, 0 also works if run asynchronously.
Console.println(sendData.available());
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
}
}
else if (voltage < 2.5) {
pressFlag = 0;
}
}
void setup() {
Bridge.begin();
Console.begin();
pinMode(LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
// run an initial date process. Should return:
// hh:mm:ss :
if (!date.running()) {
date.begin("date");
date.addParameter("+%T");
date.run();
}
}
void loop() {
checkVoltage();
if ((timeSinceLastCycle > 300000) && (transmitData > 300000)) { // If 5 minutes have elapsed without a part being produced, output that the arduino is transmitting even if not part is available
sendData.runShellCommand("curl -X POST -H \"Content-Type: application/json\" -d '{\"value1\":\"1\",\"value2\":\"Arduino Transmitting\"}' https://maker.ifttt.com/trigger/transmitData/with/key/gKRo-zSur5rj6rD5rviCaV2RHI5g56Dy0Vc0S_XJ-oO -k");
transmitData = 0;
}
}
更新：我在checkVoltage函数中添加了一系列打印语句。上面的代码已更新以反映这一点。我发现它在尝试使用sendData.runShellCommand异步时挂起。输出看起来像
1.58
1.54
5.00
Delaying
PressTime is n" -d

尝试运行ShellCommand时，网络连接是否会导致此问题？
答案 0 :(得分：1)
因此，在关注user3629249的解决方案后，此问题似乎已得到解决。现在已经有多周的无错误运行时。 user3629249，如果你想重新发布你的建议作为答案，我会接受它。感谢user3629249和Patrick Trentin的帮助！
我的更新ProcessDate函数现在包含：
if(date.available() >0){
while (date.available() > 0) {
// get the result of the date process (should be hh:mm:ss):
String timeString = date.readString();
// find the colons:
int firstColon = timeString.indexOf(":");
int secondColon = timeString.lastIndexOf(":");
// get the substrings for hour, minute second:
String hourString = timeString.substring(0, firstColon);
String minString = timeString.substring(firstColon + 1, secondColon);
String secString = timeString.substring(secondColon + 1);
// convert to ints,saving the previous second:
lastSecond = seconds; // save to do a time comparison
lastMinute = minutes;
lastHour = hours;
hours = hourString.toInt();
minutes = minString.toInt();
seconds = secString.toInt();
String currTime = hourString + ":" + minString + ":" + String(seconds);
return currTime;
}
else{
String currTime = ""; // If there is no result from the date process, return nothing. Should not happen.
return currTime;
}
}
