Question

感谢您对上一个错误的所有帮助，我能够解决它。（答案归功于：razong但现在我有另一个错误，我不知道如何修复（我知道，我听起来很愚蠢，但Processing / C ++语言不是我的强项。）它发生在第273行并读取，ArrayIndexOutOfBoundsException。

sensorHistoryDATA = subset(sensorHistoryDATA, position);

该部分代码的其余部分位于

之下

// this function sends the data out to a file and to the web

void sendDataOut() {

  // >> trim data
  String[] sensorHistoryHEAD = subset(sensorHistory, 0, 3);
  String[] sensorHistoryDATA = subset(sensorHistory, 3);
  // figure out the index of where to start reading the data
  int position = sensorHistoryDATA.length - 288; // 3 days worth = 288
  // aquire only the last x days worth of data
  sensorHistoryDATA = subset(sensorHistoryDATA, position);
  // splice the arrays back together
  sensorHistoryTrimmed = splice(sensorHistoryHEAD, sensorHistoryDATA, 3);
  // << trim data



  // write data to the file, full data
  saveStrings(dataFileName, sensorHistory);
  /*    
   if(listOfURLs.length > 0){
   // create a string for sending as POST var
   String srtTemp = join(sensorHistoryTrimmed,"\n");
   //
   for(int i=0; i<listOfURLs.length; i++){
   // save data to the web 
   postNewItem(listOfURLs[i],"sensorData="+srtTemp);
   } 
   }*/
   }

我再次没有发布到网络上，因此阻止了网络部分。

（我很抱歉，如果这不是完美的MCVE，但是，A;我不确定问题是否在代码中出现更高并影响这部分。而且B;我是StackOverflow的新手，我会尝试变得更好。）

这是处理代码的其余部分（错误在正确的位置）：（我不会将数据放到网上，这就是所有互联网部分都被注释掉的原因）

GardenBot - computer module, local-connection sub-module

beta version 2 (2011-01)

This is the code for the local-connection sub-module of the computer module of GardenBot.
This code should be run in the Processing environment (www.processing.org).
This code communicates with the brain module (Arduino) and can record the data to a text file and/or the web.

你错误地在

之前评论代码

void serialEvent(Serial p) {

savesendDataOut()方法的结束是在评论中。

提示：如果使用CTRL + t（自动套用格式），您可以在处理过程中更好地发现这些内容。
