Convert String to Integer

Processing Coding Questions

Hello,

Please format your code:
https://discourse.processing.org/faq#format-your-code

I used simulated data here and only had to remove 1 character which was the line feed ( ‘\n’).

I may be going off topic here.
Start another one if you want to continue this.

Please provide a small snippet of the Arduino code and please format properly for the forum.

Some test code without the Arduino sending:

Test Code 
String s;

void setup() 
	{
	//s = "v1m1v1m2v1m3v1m4/n";
  char LF = '\n';    // 1 character
  //Serial.println(“v1m123”); 
  s = "v1m123" + LF; // 6 characters + 1 character for LF (line feed)
  testData(s);
  }

void testData (String s)
  {
  String delim = "v1m";
  int l1;

  //String deviceData = trim(s);
  String deviceData = s;

  if(deviceData.indexOf(delim) == 0) 
    {    
    l1 = deviceData.length();
    
    String Adata = deviceData.substring(3, l1-1); //-1 for LF
    //Extract only the numerical values, I do not know why I 
    //have to subtract 2 characters from the length instead of just 1 in order to get int() to work?????
    println(Adata);
    int sensorValue = int(Adata); 
    println(sensorValue);
    }
  else 
    {
    String debugMsg = deviceData;
    print(debugMsg);
    }
  }

Here is another topic that may be of interest:

Arduino can send data that is comma delimited (or other delimiter) and terminated with a line feed (or other terminator) and Processing can receive and split it.
