while I have 424 DNA tags on order, I played with your code and did 2 things:
I made it work with the better maintained MFRC522v2 so it can be used more easily with I2C devices like the RFID2 (uses a WS1850S - a Chinese variant of the 522 but seems to work well) - if you are interested, I'll clean it up
Also, I used your code as a base to explore reading Type4 tags, im my case a RuuviTag (a Nordic nrf52 which exports config info via NFC) - I had working code for the PN532 and thought I can make it work with yours
since your code introduced the pcb argument in DNA_BasicTransceive(), I thought you might be able to shed some light on the issue? can you point me to a reference for chaining?
am I correct in assuming the block number needs to be toggled for each DNA_BasicTransceive() operaation? while your code provides the option to pass in a BN, I did not see some toggling code like you would do with the alternating bit protocol?
could be the 424 DNA cards do not need this?
thanks in advance

ps: my goal is to be able to read MifareClassic and Ultralight, and the Ruuvi tags config info
thanks for this very interesting code!
