Sudo python read.pyScan your cards or tokens. It will give you response with yellow letters if all is ok. If all is ok then you should be able to type into console now: (This may call for reboot to get this to work) You need to do some configurations to prepare connecting to this device: When you power up the Raspberry PI then the MFRC-522 RFID reader board should have one light on it. Making sure things work before we use Xojo Once you have the header pins soldered in the board and your cobbler placed on the breadboard then here is how you will want to wire the MFRC-522 card reader:
XOJO MSGBOX HOW TO
If you are not familiar with breadboards, how to place a cobbler on the breadboard or need to know how to read the color codings on the resistors then click here bellow
XOJO MSGBOX FULL VERSION
Einhugur PythonScript plugin for Xojo (don’t worry all the Einhugur plugins are free for Raspberry PI, if you don’t got licence then just download the Demo version, it will run as full version when compiled for Raspberry PI).(I paid $2.67 at some Ali Express seller, that included free shipping to Iceland) Connecting the high voltage connectors can potentially be life threatening, be careful and do at your own risk. Incorrect wiring can result in damaged relay board or damaged Raspberry PI. We do not take any responsibility for possible errors in the guide or errors that you might do wiring it up. I was worried in this project that it would end up in drama at almost all stages but it turned out to be really easy, I had no fails at any stages of this experiment. (If you have not experimented with hot air touch free soldering then I highly recommend doing so as once your there then there is no going back) I choose the angled ones so I could easily stick the board into breadboard. You have to solder the header pins into the board. This is how the kit I bought came, it has the MFRC-522 RFID reader board, 2 sets of header pins (straight and with 90 degree angle), one RFID token, and two RFID cards. This board like many other boards need fairly complex driver and since I believe Xojo should be about productivity and not always having to start from scratch at re-inventing the wheel then we will be using Python driver that already exists and then bridge the Python to Xojo, making this example very easy. In this example we are going to connect to MFRC-522 RFID reader.
