For this project we assume that the tags are the Mifare Classic 1k type and that we are only allowing one tag at a time in the antenna field. While both modules are unique in the way that they are accessed and the way they access the tags, there is a general process that is required to get the job done. Even if you don’t use a PIC and/or assembly language, the source code should at least provide you with a good idea of the specific commands required to perform each step.
RFID RC522 ARDUINO I2C EXAMPLE SOFTWARE
I also include PIC assembly software programs for performing the basic commands required by each module. This post is primarily about the information I wish I had when I started the project.
RFID RC522 ARDUINO I2C EXAMPLE MANUALS
Also, the manuals for the chips and for the Mifare tags take a bit of deciphering. While there are lots of example programs online for the modules, most of them are written in ‘C’ software for the Arduino and use the SPI interface.
So what I was looking for was a sequence of steps required to talk to the modules and to the RFID tags. If you’ve read any of my other projects you know that I like to use cheap PIC microcontrollers and program in assembly language. The two common modules use either the RC522 chip or the PN532 chip – both made by NXP. The other modules I bought operate at 13.56-MHz and use tags that can be both read and written so it’s kind of a waste to simply use them for basic security. Modules like that use read-only tags so the process is scan for the ID, store if desired, and compare against stored ID’s.
RFID RC522 ARDUINO I2C EXAMPLE HOW TO
In a previous project I detailed how to use a simple 125-kHz module to do a basic security function. Some time ago I bought three different RFID modules for experimenting. UIFlowĪfter opening and burning this example using UIFlow, place the proximity card on the Unit surface and the screen displays “True ” and the UID number of the card.NOTE: I now have Instructables that offer Arduino code for the RC522 and PN532. To get complete code, please click here.Īfter programming the RFID.ino, the IC card or the mobile phone NFC, close to the unit, moves back and forth around the unit, and the UID of the IC card or the RFID chip in the mobile phone will be printed on the screen of the M5Core.
RFID RC522 ARDUINO I2C EXAMPLE INSTALL
Before installing for M5Core, you need to install CP210X driver (you do not need to install with M5StickC as controller) Click here to view the driver installation tutorial Example 1. Currently EasyLoader is only suitable for Windows operating system, compatible with M5 system adopts ESP32 as the control core host. ( For M5StickC burning, please Set the baud rate to 750000 or 115200 ) 3. 2.After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click "Burn" to start burning.
RFID RC522 ARDUINO I2C EXAMPLE VERIFICATION
It can be burned to the master through simple steps, and a series of function verification can be performed. Every product page in EasyLoader provides a product-related case program.
