Try this right after you receive string:  
println(inString);

Try a delay() in setup() of Processing:

I added a delay(1000) to allow the Arduino to reset after serial connection to Processing and it now works. I modified the Processing setup() as follows: void setup() { size(200, 200); printArray(Serial.list()); //Added! List all the available serial ports String portName = Serial.list()[0]; myPort = new Serial(this, portNa…

I like to test code on receiving side with simulated data:

```auto
String s = "113,206,46,212,102,195,211,114,33," + "\n";

print(s);

s = s.trim(); // Trims that \n before processing string

print(s);
println();

println(s);

String [] splitData = split(s, ',');

printArray(splitData);
printArray(float (splitData));

println(float(splitData[0]));

float [] splitFloats = float(split(s, ','));

printArray(splitFloats);

```
