ProcessingSerialGraph

Processing (java-like, processing.org). Draws graph with data from serial port. Useful with arduino.

Code used in Arduino sketch

void setup()
{
    ...
    Serial.println("Columns:gyro.x{-32768;32767},gyro.y{-32768;32767},gyro.z{-32768;32767},acc.x{-2048;2047},acc.y{-2048;2047},acc.z{-2048;2047}");
}


void loop()
{
    ...sersor read

    Serial.print(gyro.g.x);
    Serial.print(",");
    Serial.print(gyro.g.y);
    Serial.print(",");
    Serial.print(gyro.g.z);
    Serial.print(",");
    Serial.print(compass.a.x);
    Serial.print(",");
    Serial.print(compass.a.y);
    Serial.print(",");
    Serial.print(compass.a.z);
    Serial.print("|");
    Serial.println(millis());
}
