I’ve got the PiicoDEV RFID Module working fine using the demo software in
Radio Frequency IDentification (RFID) uses electromagnetic fields to identify and communicate with tags. Each RFID module emits radio waves that energise the passive tag, which then responds with its own identifying number or data, as requested.
I’d really like to get it working with the nfcpy python library, but I think that needs to be on a UART or USB port. Do you know of any way tp get the PiicoDEV RFID module working with nfcpy?
Welcome to the forum!!
It doesnt look like the MFRC522(the IC used in the PiicoDev RFID module) is supported in the nfcpy supported devices list.
What were you looking to do with the sensor?
There might be some analog to the functionality you’re after
Ok, thanks Liam. I was hoping to emulate a tag containing a url/uri so that when a phone is put in range of the RFID device, the url/uri will be transmitted to the phone, just as if it was an NFC tag with a url. I got this working with nfcpy using SmartPoster and LLC (it was for NTAG215 though).
Hi Liam, I just found a proposal to add MFRC522 support to nfcpy - see
MFRC522 support · Issue #176 · nfcpy/nfcpy · GitHub. It doesn’t seem to have been implemented yet, but some good work has been done at py522/rc522.py at master · socram8888/py522 · GitHub.
I don’t have the hardware/firmware expertise to contribute to this unfortunately, but it would be great to see MFRC522 support for nfcpy.
Sorry to throw another spanner in the works but there might be some more hurdles in getting the PiicoDev module to work with the RPi.
There are a few modes that the chip can use I2C, SPI and RS232 (you want this one)
I’m not certain how to fix it, but definitely something to keep note of
Thanks Liam. I think I found another board based on the PN532 chip that should work on RS232/UART on the Rpi using the nfcpy library - see
