Microduino-NFC

Language	English

Microduino-NFC Microduino NFC is a two-way connection and identification module for close range wireless communication, work at 13.56MHz frequency, about 10cm working distance and realize the data exchange and service. Features Use PN532 highly integrated contactless reading and writing chip, contains a 80C51 microcontroller core with 40kB ROM and 1 kB RAM; Integrate the RF field detector; Integrate the data mode detector; Low power consumption mode, hardware power lost mode and software power lost mode; In reading and writing mode, support Mifare Classic encryption, which can support 212kbit/s and 424 kbit/s two kinds of higher data transfer rate; In FeliCa mode，support 106kbit/s, 212kbit/s and 424kbit/s communication rate; Integrate the NFCIP-1's RF interface, transfer rate up to 424kbit/s. Specifications 2.7V~5.5V power; Specific I/O port to contorl external device; In reading and writing mode, the default working distance more than 50mm, actually distance depends on antenna size, tuning, and power supply; In NFCIP-1 mode, the default working distance more than 50mm, actually distance depends on antenna size, tuning, and power supply; In FeliCa mode, the default working distance more than 100mm, actually distance depends on antenna size, tuning, and external field strength; Reading and writing mode supports ISO/IEC 14443A/MIFARE mechanism, FeliCa mechanism and ISO/IEC 14443B mechanism; FeliCa mode supports ISO 14443A / MIFARE mechaniam、card operation mode and FeliCa mechanism; Use IIC communicate method.

Note: this program only can read ISO14443A four bytes label Prepared hardware：Microduino FT232R, Microduino Core and Microduino NRF Prepared software：Adafruit_NFCShield_I2C library and Arduino IDE； Download the library and test program, uncompress the library and copy to libraries folder of Arduino IDE; Open the ”Microduino_Write_cards” test program, compile it and select the "Microduino Core (Atmega328P@16M,5V)" to download； Open the serial monitor, select the baud rate, if successed, serial will retuen some data and print “Please press 'f' to format.....”、“Please press 'r' to Rewrite data......”； Step 1：Input ’f’ to format the label, you can see the format progress; Step 2：Input ’r’ to rewrite new data, if successed, then return ”Writing URI to sector 1 as an NDEF Message”. If failed, repeat from step 1 until data was wrote successfully. Use a mobile phone with NFC label to test There are three wrote data: Network address const char * url = "microduino.cc"; uint8_t ndefprefix = NDEF_URIPREFIX_HTTP_WWWDOT; Mail const char * url = "mail@example.com"; uint8_t ndefprefix = NDEF_URIPREFIX_MAILTO; Phone number const char * url = "51508987"; uint8_t ndefprefix = NDEF_URIPREFIX_TEL; User can choose in the program, the annotation of "//" can be deleted, and can define your own content.
