Hello Charlotte

I followed several times your installation instructions as described.

I always get the following error when you run the read.py

pi@raspberrypi ~ $ sudo python read.py

Traceback (most recent call last):

File "read.py", line 3, in <module>

uid=nxppy.read_mifare()

AttributeError: 'module' object has no attribute 'read_mifare'

pi@raspberrypi ~ $

hast du mir da einen type?

Dank dir aus der Schweiz

I get the following error after running the script:

File "read.py", line 5

uid=nxppy.read_mifare()

IdentationEror:expected as indented block

Any suggestions for how to get this working? I've been trying for days to get the shield up and running, so any help is more than welcomed. And thank you for this tutorial!

Thanks for the tutorial for the EXPLORE NFC board. I appreciated it.

The Explore NFC board isn't supplied by Farnell now is seems. Will this project work with any other NFC boards?

NOTE: the code used in this tutorial, as described in the text in bold, is now deprecated in the current release of nxppy. Anyone who wants to continue using this code, please download and install a copy from the releases page, NOT pip. I will be updating the code to use version 1.2 in the next few weeks, but for now please refer to the readme file of the aforementioned github repo if you would like to update your own code to use the new version.

Cheers!

Dear friends.

I am write a C library using SPI communication for interface the Board NFC EXPLORE PN512 with a micocrontroller 8 bit, 16 bit or 32 bit. This because lot off pleople dont has Raspeberry or prefere use this Board with another MCU, like in my case.

After one week working in this projects I can manager the NFC EXPLORE register, for exemaple write and read the FIFO BUFFER, clear the configuration, transmitte data to RF anntena.

Now I need any help to solve the last problem that is: Cannot send data to MIFARE card to read the UID or other data that is store in the card EEPROM.

Below is my code:

// THIS LINES OF CODE CONFIGURE THE DEVICE TO ENABLE RF ANTENA AND

EXPLORE_NFC_PN512_ControlReg(0x05);

EXPLORE_NFC_PN512_TxAutoReg();

EXPLORE_NFC_PN512_RxThresholdReg();

EXPLORE_NFC_PN512_RFCfgReg();

EXPLORE_NFC_PN512_GsNOnReg();

EXPLORE_NFC_PN512_TxControlReg();

// CLEAR THE FIFO BUFFER BEFORE WRITE THE COMMAND DO BE SEND TO RF

EXPLORE_NFC_PN512_Clear_Fifo_Buffer();

EXPLORE_NFC_PN512_WRITE_MB_INTO_FIFO_BUFFER(0x26); // value write 0x26h command do quest card

// NOW SEND THE FIFO CONTENT TO ANNTENA AND WAIT FOR MIFARE CARD RESPONSE

// IN THIS PARTICULAR CASE I WAITING FOR 04h 00h

EXPLORE_NFC_PN512_Start_Send();

EXPLORE_NFC_PN512_Transmit();

EXPLORE_NFC_PN512_Transceive();

_delay_cycles (50000);

nBytes=EXPLORE_NFC_PN512_GetFifoLevel(); // Get FiFo level

_delay_cycles (50000);
