Hello Good Day!
Please help me on getting the solution about this.The processing has an output but it is not copied on the text file.All i want is to copy the output of the preccing which is from the arduino program.The output is for example (1 2 3)...........(2 3 4).....This values is for acceleration on X Y Z axis which is program ont he arduino. Pls help me...
Thanks for the answer.

byte[] buff; //buff input String read from serial com port
float[] r;
PrintWriter output; //to output to text file
int OFFSET_X = 0, OFFSET_Y = 0, OFFSET_Z=0;
//These offsets are chip specific, and vary.
void setup()
{
sp = new Serial(this, "COM6", 9600); //creating new serial communication port
buff = new byte[128];
r = new float[5];
// Create a new file in the sketch directory
output = createWriter("wew54.txt");
}

{
int bytes = sp.readBytesUntil((byte)10, buff); //receiving the input String from the serial port
String mystr = (new String(buff, 0, bytes)).trim();

return;
}
setVals(r, mystr);
float x = r[0], y = r[1], z = r[2];
println(x+ "\t" + y + "\t" + z+"\t"); //printing to screen
output.println(x+ "\t" + y + "\t" + z+"\t");
//printing to text file
