multiple rfid readers raspberry pi I'm trying to connect x9 RC522 RFID readers to an RPI. I'm wondering if it can be done using the standard RPi GPIO pins or if I need some other controller. Also, it's worth mentioning that it will need to be able to distinguish between the readers, and know which one is providing which data. Sruti Rao reports. [email protected] February 5, 2014.

It's long forgotten, but in 2006 , the NFL wild-card scenario list was three miles long heading into the final week of the regular season.

I'm trying to connect x9 RC522 RFID readers to an RPI. I'm wondering if it can be done using the standard RPi GPIO pins or if I need .

- connect the second RFID reader as listed in the Connection Diagram from the . The problem is the Raspberry Pi only has a single serial port. You could add . You can use the RST Pins to select the reader you want to use. Connect all the other pins in parallel (see schematic below). Just set all the RST pins to low, except the one on the pin you want to use.

For my project, I need to use four RFID readers (the ID-20LA Innovation). Each . I'm trying to connect x9 RC522 RFID readers to an RPI. I'm wondering if it can be done using the standard RPi GPIO pins or if I need some other controller. Also, it's worth mentioning that it will need to be able to distinguish between the readers, and know which one is providing which data. - connect the second RFID reader as listed in the Connection Diagram from the link above, but with this modification: instead of connecting the reader's NSS signal (pin 8) to RasPi GPIO signal SPI CE0 (pin 24), connect it to RasPi GPIO signal SPI CE1 (pin 26). The problem is the Raspberry Pi only has a single serial port. You could add USB hubs, and a ton of USB-ttl serial ports. Or you could add a RoboPi, and use that to read up to 24 RFID readers, concentrating the data for your Pi.

Just set all the RST pins to low, except the one on the pin you want to use. For my project, I need to use four RFID readers (the ID-20LA Innovation). Each one needs their own tx/rx pins. Can anyone suggest any pi hats/bonnets or thoughts on how to wire these up?For university I have to connect multiple RFID readers to my raspi. Ideally 8 at a time. However after weeks of testing I have not managed to make it work. I figured out that the setmode GPIO.BOARD allows me to talk to all the pins I want and set them high for example.

You can learn how to setup your RFID RC522 Reader/Writer as a way of checking attendance by following our Raspberry Pi powered RFID attendance system guide. We will be going into more depth with these scripts and the RFID chip in later tutorials. This guide shows how to connect an RFID RC522 to a Breadboard and then to the Raspberry Pi's GPIO Pins, although you could also wire the components straight to the Pi. Simply connecting 7 of the Raspberry Pi's GPIO pins to the RFID RC522 reader is . So I'm currently working on a project where four NFC-tags need to be scanned by four readers, each of them being assigned to their own reader. After some searching, I came across the RC522 RFID readers and bought them, thinking I could just easily connect them and use online resources to learn how to program them.The SparkFun M6E Nano Simultaneous RFID Tag Reader (SRTR for short) has numerous features that make it a huge leap forward over other RFID readers.
