#rc522 — Public Fediverse posts

I made this #rfid reading contraption with #rc522 and #esp32 TTGO T-Display (tried Arduino LCD-keyshield, but it was blocking pins).

It was more complicated than I anticipated (as usual), since the default SPI bus was taken by the display and pins were not even made available, so I had to use the second hardware SPI of the ESP32 (HSPI/VSPI) with alternate set of pins.

This required the use of a different MFRC522 library, which would allow me to use alternate GPIO pins.

Next step: copy-paste

Gar nicht mitbekommen dass M5Stack den #RC522 #NFC Reader mit einem #WS1850s Chip von WiseSun ersetzt hat https://shop.m5stack.com/products/rfid-unit-2-ws1850s

@thinkpad hmmm, wird die Karte denn im Feld überhaupt erkannt? Hatte mal vor knapp 10 Jahren Probleme mit so einem #RC522 https://regnerischernachmittag.wordpress.com/2013/08/03/5euro-rfidnfc-modul-rc522-zum-auslesen-von-mifare-tags/

Ich packe wieder Hörbücher auf den #tonuino, einer #MP3 #Musikbox auf Basis von einem #Arduino Nano und MP3-Playermodul #DFPplayer und #RFID Reader #RC522

Danke an die Erfinder: https://www.voss.earth/tonuino/
