Many years ago, i did a simple RFID reader program.

What it does is to read the RFID tag and if the ID number is stored in the PIC's ram, then it will make a port high.

That is the whole program.

I haven't tried anything yet to embed the above RGB code. What i would like to do with this code, is to work on the backround as an effect, when:

The RFID tag is valid: to light the RGB ring in Green, then to continue working on the backround.
The RFID tag is not valid: to light up the RGB ring in LED.

I will try without interrupt and i will add the RFID code inside the main of the RGB code. Will let you know.
