Loop getting stuck and not looping

adamandkate83 · October 6, 2024, 12:11am

I have an esp32, pn532 NFC, and an i2c oled display.

I have a problem where the button press is not being detected unless I tap the NFC reader. I highly suspect its somehow getting stuck somewhere in void loop. but i have no idea where..

In the loop if i disable checkNfcTag() the button then gets detected

So something in this section of code is causing the loop to get stuck...

any advice appreciated

void checkNfcTag() {
  uint8_t success;
  uint8_t uid[] = { 0, 0, 0, 0, 0, 0, 0 };  // Buffer to store the returned UID
  uint8_t uidLength;

  // Wait for an NFC card
  success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, uid, &uidLength);

  if (success) {
    // Display the UID to the serial monitor
    Serial.print("Found an NFC tag with UID: ");
    for (uint8_t i = 0; i < uidLength; i++) {
      Serial.print(uid[i], HEX);
      Serial.print(" ");
    }
    Serial.println();
    nfc.SAMConfig();  // Reinitialize the NFC reader for the next scan

    // Handle the NFC tag event
   // handleNfc();
  }
}

Sounds like your button press logic is flawed. Maybe use a library of proven code?

adamandkate83 · October 6, 2024, 12:28am

sorry in what way. are you able to give me some more detail? im kinda stumbling through all of this

sonofcy · October 6, 2024, 12:32am

Button code seems easy, but it is not. I would concentrate on that by sticking in Serialprintln in a few places to see if what is happening is what you expected. OR use a library, there are probably hundreds.

van_der_decken · October 6, 2024, 12:33am

Think about this line. And the comment. Does that sound like non blocking code to you?

adamandkate83 · October 6, 2024, 12:49am

thankyou very much.

so i made the below change and its now working... mostly.

I find i need to press the button a couple of times or press and hold to make it work. so i think the nfc is still tripping it up a little. is there a better way of doing this?

void checkNfcTag() {
  Serial.println("Checking for NFC card...");

  // Check if there is an NFC card in range
  uint8_t success = nfc.inListPassiveTarget();

  if (success) {
    Serial.println("NFC card detected!");

    // If a card is detected, retrieve the UID
    uint8_t uid[] = { 0, 0, 0, 0, 0, 0, 0 };  // Buffer to store the UID
    uint8_t uidLength;

    // Try to read the UID of the card
    success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, uid, &uidLength);

    if (success) {
      Serial.print("UID Length: ");
      Serial.print(uidLength, DEC);
      Serial.println(" bytes");

      Serial.print("UID Value: ");
      for (uint8_t i = 0; i < uidLength; i++) {
        Serial.print(" 0x");
        Serial.print(uid[i], HEX);
      }
      Serial.println("");

      delay(1000);
    } else {
      Serial.println("Error reading UID");
    }
  } else {
    Serial.println("No NFC card detected");
  }
}

van_der_decken · October 6, 2024, 12:51am

Add up all the delay(...) calls in your various disney functions. Your button will not be detected until all those delays are finished.

adamandkate83 · October 6, 2024, 12:53am

cant be them can it? they only get called on successful card read. or should be anyway.

the button being slow is when no card is being used

van_der_decken · October 6, 2024, 12:55am

Did you mention that the button was slow only when no card was being used? Then how was anyone to know that?

adamandkate83 · October 6, 2024, 12:56am

apologies
