Function not working with existing Code

Projects Programming

Hi I created a function called VOICE(){}, and its suppose to replay a recorded message at a specific time with an RTC. The message will replay just fine, but when I include the VOICE() function with the code I created for my touch screen, the touch screen no longer responds when I press on it.

    if(x == 0 && now.hour () == 18) {
 tft.drawRect(45, 0, 40, 40, WHITE);
// VOICE();
         if (p.y > 800  &&  p.x > 600 && p.z > MINPRESSURE && p.z < MAXPRESSURE){
             Serial.println ("I'M ON A");
             tft.drawRect(45, 0, 40, 40, BLACK);
             delay(100);
             SERVO_1();
             x=1;}
             
             if (now.hour() == 19){
               x = 0;
             }
                      

    }

Above is the code I wrote, but I commented out the VOICE() function to show that the touch screen works when VOICE() is commented out, but stops working when it is included with the code. Is there a way to make the VOICE() function work until the touchscreen is pressed?

There isn't enough information there to tell. Please post the whole sketch so we don't have to guess what the rest of your code is doing.

Write another sketch, which just tests the functionality of the voice() function, without the complications
of dealing with the touch screen.

Then, when you have tested it thoroughly, add it to the touch screen sketch.

// Source string MUST be inside a PSTR() declaration!

}

// Same as above, with trailing newline
void progmemPrintln(const char *str) {
  progmemPrint(str);
  Serial.println();
}

The code for the function voice() is

int PULSE = 48; // pulse for voice recorder


void VOICE() {
pinMode(48, OUTPUT);
   digitalWrite(PULSE,0);
   delay(5000);
   digitalWrite(PULSE,1);
   
}

F.Y.I, I'm using an Arduino MEGA 2560 and the main code was made by altering the sample tutorial from Adafruit for their TFT touch screen. If there are any unnecessary lines, please feel free to address them. Thanks :slight_smile:

void VOICE() {
pinMode(48, OUTPUT);
   digitalWrite(PULSE,0);
   delay(5000);
   digitalWrite(PULSE,1);
   
}

probably the delay(5000). It'll make the touchscreen unresponsive. You'll need something like the blink without delay script.

Hey mistergreen, thanks for the link. I figured out that the delay was the issue, because the serial monitor would increment every 5 seconds (which is the time I've set up for the delay). I looked into the millis() reference on arduino, but it wasn't quite what I was looking for. Your link seems to be just the one I was looking for. Thank you!!
