https://devzone.nordicsemi.com/f/nordic-q-a/75450/rc522-libraryHi! 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 NRF52832en-USTelligent Community 13Tue, 25 May 2021 09:19:51 GMThttps://devzone.nordicsemi.com/thread/311374?ContentTypeID=1Tue, 25 May 2021 09:19:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:19b837f1-ebf7-4e54-a355-42e6bd66ce02haakonsh[quote user="kirill9129"]Could you please leave a link to the lib&nbsp;from STM?[/quote] <p>&nbsp;I don&#39;t know of any such library.<br /><br />The page you linked to does not load properly:&nbsp;<br /><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/Blank.PNG" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/311367?ContentTypeID=1Tue, 25 May 2021 08:58:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c4847c8a-69e0-4d29-ab2e-c94071026c04kirill9129<p>Could you please leave a link to the lib&nbsp;from STM?
