Step 1: Describe your environment

• OS version: _all____
• Arduino IDE version: _all____
• MFRC522 Library version: _master-branch____
• Arduino device: __all___
• MFRC522 device: _all____

Step 2: Describe the problem

The helper function printDec() in the NUID.ino example file has a cut and paste error from the HEX version. You don't want a leading zero if the value is above 0x10. /**

• Helper routine to dump a byte array as dec values to Serial. / void printDec(byte buffer, byte bufferSize) { for (byte i = 0; i < bufferSize; i++) { Serial.print(buffer[i] < 0x10 ? " 0" : " "); Serial.print(buffer[i], DEC); } }

Affected file(s) or example(s):

• Filename 1
• Filename 2

Steps to reproduce:

1. ---

2. ---

3. ---

Observed Results:

if the uid happens to be 9, 15, 16, 240, you get the output " 09 015 16 240"

Expected Results:

I would expect a 3 digit value for each byte 000 to 255 or at least consistent leading white space " 009 015 016 240" or " 9 15 16 240"

Relevant Code:

 * Helper routine to dump a byte array as dec values to Serial.
 */
void printDec(byte *buffer, byte bufferSize) {
  for (byte i = 0; i < bufferSize; i++) {
    Serial.print(buffer[i] < 0x10 ? " 0" : " ");
    Serial.print(buffer[i], DEC);
  }
}
