AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi 4. Preparation of the demo software for the Raspberry Pi All example software projects are being delivered within an installer. We provide installer for the platforms Linux x86 and Windows x86. The installer cannot be executed on the Raspberry Pi because of the ARM architecture. To obtain the example projects, please execute the installer.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi 5. Login to the Raspberry Pi and starting the software This section describes how to compile and run the software for the EXPLORE-NFC demo board. The steps shown here are especially for the Polling project. In principle the description can be transferred to the other projects easily. The only procedural differences will be the naming of the folders. 5.1 Login to the Raspberry Pi 1.

The EXPLORE-NFC board in conjunction with this software is able to detect MIFARE Ultralight, MIFARE Classic, MIFARE Plus and MIFARE DESFire cards. To stop the software, please press Ctrl + C on the keyboard. AN11480 Application note COMPANY PUBLIC All information provided in this document is subject to legal disclaimers. Rev. 1.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi 6. How does the Polling software work? Imagine in a Hotel you got a key card for your room and want to check what card it is. Is it contactless card? And if it is a contactless card, what type of card is it? Or if you got a contactless public transport monthly pass. With the polling software you can get this information immediately.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi commands are named “AppSelection1” and “AppSelection2”. Only one of those commands need to be sent to the card If both tries to select the PSE file are answered with an error, we can assume that we have no PSE crad in the field. When the return value is positive, the PSE name will be taken from the return answer and the function “Compare” checks whether it is valid or not.

Card Emulation project Suppose you want to organize an outdoor game similar to Paper Chase and you want to give it a digital touch. In addition you also want to give some audience the opportunity to follow the game live. Then Card Emulation is the key technology for that purpose.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi A specification to store data for any kind of service and application is specified in the NFC Forum and it is called NFC Data Exchange Format. Storing NDEF formatted data inside contactless card products as mapping models as well as the management of NFC forum device as a specific platform such as a NFC Forum Type 4 Tag are defined in [18.].

AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi The first blocks describe the initialization of the necessary layers and components independent of the card emulation. After the layers have been initialized, the card emulation can be initialized too. After applying the protocol settings, the PN512 waits for a successful activation of the card side. This activation can be done for example by an NFC enabled mobile device.

AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi Now the message gets sent to the NFC application that has been executed on the Raspberry Pi previously. 8. P2P SNEP client project Imagine you receive an image via e-mail and want to upload it to your mobile phone. If you have no cable at hand, you need to fiddle about with Bluetooth or WiFi. That is the point where NFC – P2P makes the game.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi 8.2 Choosing the NDEF message By default the software sends an image of the NXP logo as NDEF message. There are more NDEF messages prepared in dedicated header files (see Table 1). Only a single header can be compiled with the SNEP client application. To choose another content of the NDEF message for transmission just do following modifications in the Error! Unknown document property name./source/ndef_message.c. 1.
AN11480 NXP Semiconductors Quick Start Up Guide for EXPLORE NFC working with Raspberry Pi 7. Type the following command: cmake ../source 8. Compile the source with the command make 9. Run the program with the command ./Snep_client 8.5 Timers In the NXP Reader Library P2P there is the OSAL module – NxpRdLib_PublicRelease/comps/phOsal encapsulating memory allocation and time related functions. Time related functions are more precisely described in [10.].
