Im triying to learn more about RFID reading and writing on T5557 cards. I'm using this tutorial
The diference is that the arduino i'm using is the Arduino Mega 2560
Using the IDE Arduino 22 and the code to to read and write the T557 cards.
The problem is that when I try to upload the code even without the RFID shield it gets stuck. The message "Uploading" keeps apearing but I have waited 30 minutes and nothing else happens.
Triying to find the source of the problem. I tried the inverse engeneering and reached the next conclusion.
If I comment the last 3 lines on the loop():
Serial.println(); Serial.println("Card ready!!!"); delay(5000);
The code is successfully uploaded.
Does this code reachs the limit of memory from the Mega 2560?
Is it something else?
thanks in advance
