Parallax RFID sensor and Mega 2560 problems

Hi All,

I have just received my Parallax RFID sensor to use with my Mega 2560 but I cant get it to work =(

I am following this guide but I dont know what I am doing wrong.

I have done some debugging and it seems that it wont get past the first ‘if(Serial.available() > 0)’ at the start of the loop.

I have run out of ideas and can’t seem to find the answer on Google.

Any help would be greatly received!

Thanks in advance,


Ok - I tried using the serial software and now its working.

But ... does anyone know where I can also write to the RFID chip (I have the reader writer version of the Parallax)
