Hi All I have been playing with the PN 532 but have hit the wall with it . Using Cesars PN 532 library I can pull back a Firmware version but that’s it . Using the other Nodes ie unpack UID just gives no results . I am using the board connected as an I2C Device and have a separate line for IRQ to A0 as requested by the Node . I dont have a lot of Hair to start with but this problem is causing it to rapidly diminish 🙂 , Any Help or advice would be gratefully received . Thanks ---

hi, for 532 use the XOD native nodes, my library is for rc522 ---

Hi Cesar , Thanks for replying . I am using the 532 Native node ( apologies , i was rushing doing the inquiry) . Iam not convinced I have the connections correct though . I have tried the SCL SCA connections nearest the USB socket on the UNO and various other configurations but do not seem to be getting very far ( are pullup resistors needed ?). Would you be able to confirm the connections ? . XOD is a Great piece of software and has opened Arduino up for me . Love it ---

Hi Seems I have some Library issue . I was getting a few different errors so removed the libraries and reloaded them . I now get .

So I tried numerous things . Stripped off xod then reloaded and installed the libraries through xod for PN532 . When i do this i get In file included from C:\Users\MarkC\AppData\Local\Temp\xod\_temp\_sketchbookHkW3th\xod\_1588247553753\_sketch\xod\_1588247553753\_sketch.ino:979:0: C:\Users\MarkC\AppData\Local\Temp\xod\_temp\_sketchbookHkW3th\libraries\Adafruit\_PN532/Adafruit\_PN532.h:34:10: fatal error: Adafruit\_SPIDevice.h: No such file or directory #include \ Any help advice would be most tremendous , Thanks ---

When trying to compile a light blue warning appears, you must click to download the library and recompile. If not downloaded, you should do it manually from > **[adafruit/Adafruit-PN532](https://github.com/adafruit/Adafruit-PN532)** > > Arduino library for SPI and I2C access to the PN532 RFID/Near Field Communication chip - adafruit/Adafruit-PN532 and add the unzipped folder in `/user/xod/ __ardulib__ /` ---

Hi Cesar Thanks for the information . I still get the error but looking in the unzipped package I dont see the SPI file . ---

So I just tried the PN532 directly through the Arduino IDE and UNO says hello but nothing back from the PN532 so I am pretty sure the board is a duffer . Thanks for your help its been a good learning experience ---

I can not contribute any experience with PN532, because I do not have that hardware. I only have the rc522 for which I made a library but it is not yet complete Br ---

I have an RC522 also . Is the library you have for it so far capable of unpacking the card UID ? ---
