How to send data from arduino after mousepressed()?

rojascan

Basically what I want to do is to send values of a potentiometer to the processing and show them in the console after I press a button in the processing program. However, I'm not getting what I want.

My program does a few things that already worked. It has three different modes to move a servo and those are in the main screen of my program. And I've got another screen when I press the button and some of the values of the potentiometer are shown. However, those values don't keep showing unless I press the button again.

This is the relevant arduino code:

void loop ()
{

  if (Serial.available()) {
    val = Serial.read();
  }
 //val is send from processing to the arduino to change modes 
  switch (val) {
    //-------------------------- Close Modes----------------------//
    case 0:
        digitalWrite(ledPot, LOW);
        digitalWrite(ledCPM, LOW);
        digitalWrite(ledFSR, LOW);
      break;
    //--------------------------CPM Mode----------------------//
    case 1:
        cpmMovement();
        digitalWrite(ledCPM, HIGH);
        digitalWrite(ledPot, LOW);
        digitalWrite(ledFSR, LOW);
      break;
    //--------------------------POT Mode----------------------//
    case 2:
        digitalWrite(ledPot, HIGH);
        digitalWrite(ledCPM, LOW);
        digitalWrite(ledFSR, LOW);
        potMovement();
      break;
    //--------------------------FSR Mode----------------------//
    case 3:
        digitalWrite(ledPot, LOW);
        digitalWrite(ledCPM, LOW);
        digitalWrite(ledFSR, HIGH);
        fsrMovement();
      break;
    //---------------------Calibration Mode-----------------------//
    case 4:
        digitalWrite(ledPot, HIGH);
        digitalWrite(ledCPM, HIGH);
        digitalWrite(ledFSR, HIGH);
      break;
    //----------------Sending Values--------------------//  This is the relevant block
    case 5:
        digitalWrite(ledPot, LOW);
        digitalWrite(ledCPM, LOW);
        digitalWrite(ledFSR, HIGH);
        stateCAL == true;
        while(stateCAL == true){
        sendMaxValue();
        }
     break; 

  }
}

void sendMaxValue(){ //Function which sends the values to the console
  unsigned long startTime = millis();
  long calibrationTime = 3000;

  while(millis() - startTime <= calibrationTime) {
    maxforce = analogRead(Pot)/4;
    if (maxforce > maxReading) maxReading = maxforce;
    Serial.print(maxReading);         
    Serial.print('\t');         
    Serial.print(maxforce);
    Serial.print('\t');         
    Serial.print(startTime);
    Serial.print('\t');         
    Serial.println(millis() - startTime);

  }

  if (millis() - startTime > calibrationTime){
    stateCAL = false;
    Serial.println("Falso");
    Serial.print("After 5 seconds, the maximum reading was: ");
    Serial.println(maxReading);
    maxReading = 0;
  } 

}

And this is the relevant processing code:

void mousePressed() {
  println("Coordinates: "  + mouseX + "," + mouseY);
  if (pressedCPMButton && currentColorCPM==butColor) { //Changing color CPM to pressed button color
    currentColorCPM = butpreColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(1);   //Send 1 to port
    println(1);
  } else if (pressedCPMButton && currentColorCPM==butpreColor) {
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(0);   //Send 1 to port
    println(0);
  }
  if (pressedPOTButton && currentColorPOT==butColor) {
    currentColorCPM = butColor;
    currentColorPOT = butpreColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(2);   //Send 1 to port
    println(2);                                    //Send 2 to port
  } else if (pressedPOTButton && currentColorPOT==butpreColor) {
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(0);   //Send 1 to port
    println(0);
  }
  if (pressedFSRButton && currentColorFSR==butColor) {
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butpreColor;
    currentColorCAL = butColor;
    myPort.write(3);   //Send 1 to port
    println(3);                                  //Send 3 to port
  } else if (pressedFSRButton && currentColorFSR==butpreColor) {
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(0);   //Send 1 to port
    println(0);
  }
  if (pressedCALButton && currentColorCAL==butColor) {
    currentScreen = 1;
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butpreColor;
    myPort.write(4);   //Send 1 to port
    println(4);                                  //Send 4 to port
  } else if (pressedBACKButton) {
    currentScreen = 0;
    currentColorCPM = butColor;
    currentColorPOT = butColor;
    currentColorFSR = butColor;
    currentColorCAL = butColor;
    myPort.write(0);   //Send 1 to port
    println(0);
  }

  if (pressedSTARTCALButton) {     //This is the bit that isn't working well.
    if(myPort.available() > 0){
    }
    myPort.write(5);     //Send 5 to port
    println(5);
    valforce = myPort.readString();
    println(valforce);
  }
}

What does the code for (pressedSTARTCALButton) look like - is this a boolean that stays true? You can trial it by changing this temporarily to if (true) { which shows you where the error is - I wonder if it's around the bit where pressedSTARTCALButton is set instead of this code?

fuzzySi

Also, try this code instead ?

while (myPort.available() > 0) { String valforce= myPort.readString(); if (valforce != null) { println(valforce); } }

Thank you for your answer!
