RC522 Library

[kirill9129]

Hi! I am trying to write code on MFRC522 to read data from RFID tags and write data to them, but the datasheet leaves much to be desired, and libraries are available only for Arduino and STM.
Is there a library for working with this microcircuit on NRF52832?

We've got a library for the PN532, Adafruit PN532 NFC/RFID Controller Shield.

I guess you'll have to port the STM library, hopefully you'll only need to re-write the SPI read/write functions to fit our spi driver/HAL. 

Also note NXP's statement about the MFRC522: "Not recommended for new designs. For new designs, please use recommended product CLRC663 plus."

Could you please leave a link to the lib from STM? I took from here: 
https://stm32f4-discovery.net/2014/07/library-23-read-rfid-tag-mfrc522-stm32f4xx-devices/ rewrote the functions read and write, but it still doesn't work. Function TM_MFRC522_Check(CardID) not return "MI_OK".

 I don't know of any such library.
