I am looking to connect multiple MFRC522-readers to the same SPI-bus on an Arduino Mega. I am using the exact standard code from https://github.com/alex5imon/Arduino-RFID/blob/master/two_readers/two_readers.ino: I have problems with multiple RFID (MFRC522) usage. I use the MFRC522.h library from GitHub - miguelbalboa/rfid: Arduino RFID Library for MFRC522, and I want to read 8 RFID modules with one Arduino Uno, but I have managed only 2! I connect all the SPI pins, SS1 to pin10 and SS2 to pin2.
I'm trying to build a project using multiple RFID reader. I need to read 7 different chips simultaneously to detect different patern that I would then send to a raspberry pie to display the correct result on a screen.
I am currently trying to control at least 16 RFID readers (RC522) over SPI communication. The setup is like this: 1 mainboard PCB with 16 sockets for ribbon cable connectors. 16 satellite board PCBs, each with ribbon cable connector and a header for the RFID reader. Multiple SPI devices on the same bus shouldn't be a problem. I would try the following steps to narrow down the problem: Add Pull-Up resistors to each CS line (10k should be enough)Example sketch/program showing how to read data from more than one PICC (that is: a RFID Tag or Card) using a MFRC522 based RFID Reader on the Arduino SPI interface. Warning: This may not work!Interfacing Arduino with 13.56MHz ISO14443 RFID tags using NXP MFRC522 reader modules. By default, these readers use the SPI interface, although the chip also supports UART and I2C. Datasheet can be found here. For a comparison of alternative readers, see https://www.patreon.com/posts/rfid-roundup-23115452.
The MFRC522 data sheet 8.1.2.3, refers to using SPI to read and write register addresses within the MFRC522 rather than accessing two MFRC5 on the same SPI bus. The only way to use SPI for 2 separate devices is to run separate CS lines to the CS pin on each IC.Is it possible to connect multiple RFID-RC522 readers to the same 3.3V, RST, GND, IRQ, MISO, MOSI and SCK pins if you use a different pin for each SDA? If so, this would save me a lot of pins. So far, I have only seen direction on how to connect one RFID-RC522 to an Arduino. I'm putting together a Raspberry Pi controlled LEGO Train Layout. Each Locomotive Engine has a RFID Tag on its underside. I want to have multiple RFID Readers dotted around the Layout in order to detect which Locomotive Engine is where. Then Slow, Stop or switch Engine to other track. I am looking to connect multiple MFRC522-readers to the same SPI-bus on an Arduino Mega.
