NFC

近场通信(Near Field Communication,NFC),又称近距离无线通信,是一种短距离的高频无线通信技术,允许电子设备之间进行非接触式点对点数据传输,在十厘米(3.9英吋)内交换数据。这个技术由免接触式射频识别(RFID)演变而来,由飞利浦、诺基亚和索尼共同研制开发,其基础是RFID及互连技术。近场通信是一种短距高频的无线电技术,在13.56MHz频率运行于20厘米距离内。其传输速度有106 Kbit/秒、212 Kbit/秒或者424 Kbit/秒三种。目前近场通信已通过成为ISO/IEC IS 18092国际标准、EMCA-340标准与ETSI TS 102 190标准。NFC采用主动和被动两种读取模式。

RFID

射频识别(英文:Radio Frequency IDentification,缩写:RFID)是一种无线通信技术,可以通过无线电讯号识别特定目标并读写相关数据,而无需识别系统与特定目标之间建立机械或者光学接触。无线电的信号是通过调成无线电频率的电磁场,把数据从附着在物品上的标签上传送出去,以自动辨识与追踪该物品。某些标签在识别时从识别器发出的电磁场中就可以得到能量,并不需要电池;也有标签本身拥有电源,并可以主动发出无线电波(调成无线电频率的电磁场)。标签包含了电子存储的信息,数米之内都可以识别。与条形码不同的是,射频标签不需要处在识别器视线之内,也可以嵌入被追踪物体之内。许多行业都运用了射频识别技术。将标签附着在一辆正在生产中的汽车,厂方便可以追踪此车在生产线上的进度。仓库可以追踪药品的所在。射频标签也可以附于牲畜与宠物上,方便对牲畜与宠物的积极识别(积极识别意思是防止数只牲畜使用同一个身份)。射频识别的身份识别卡可以使员工得以进入建筑锁住的部分,汽车上的射频应答器也可以用来征收收费路段与停车场的费用。某些射频标签附在衣物、个人财物上,甚至于植入人体之内。

www.elechouse.com PN532 NFC RFID Module User Guide Version 3 Introduction NFC is a popular technology in recent years. We often heard this word while smart phone company such as Samsung or HTC introduces their latest high-end phones. Almost all the high-end phones in the market support NFC. Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. For electronics geeks, we also want to use NFC technology to make our own things. So we build this NFC RFID module. This module is built around NXP PN532. NXP PN532 is very popular in NFC area. And the company offers much technology document to help developers. We developed this module based on the official document. To make things easier, we also build library for this module. We almost break out all the IO pins of NXP532 on this module. Users could easily connect and play. With our Arduino Sensor Shield , it is very easy to plug and play. However, if users want to use other interface such as UART or SPI, this module also makes it easy to connect those pins. www.elechouse.com We have updated this module to version 3. Compared with V2, V3 have the following improvement: 1. Smaller: the size now is as small as 42.7mm*40.4mm*4mm 2. Easy to change mode: with a small SMD toggle Switch, it becomes very easy to change among IIC, SPI and HSU modes 3. Longer distance: the reading distance becomes 5~7cm, compared with 4~6 cm of last version 4. Add software to support NFC with Android Phone Features 1. Support II2, SPI and HSU (High Speed UART) 2. RFID reader/writer mode support  Mifare 1k, 4k, Ultralight, and DesFire cards    ISO/IEC 14443-4 cards such as CD97BX, CD light, DesFire, P5CN072 (SMX) Innovision Jewel cards such as IRT5001 card FeliCa cards such as RCS_860 and RCS_854 3. Plug and play, Arduino compatible 4. Built in PCB Antenna, with 5cm~7cm communication distance 5. On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI 6. Work as RFID reader/writer 7. Work as 1443-A card or a virtual card 8. Support NFC with Android phone 9. Small size: 43mm*41mm*4mm Interface www.elechouse.com  VCC: 3.3V~5V   I2C/UART: 3.3V~24V TTL SPI: 3.3V TTL with 100 ohm resistors in series. It could be connected directly to 5V interface of microcontroller such as Arduino. The I2C and HSU shares the same pins. The definition of IIC pins is printed at front and the HSU’s is printed at the back. The HSU mode is configured as the default mode. But you could change the interface by setting the toggle switch. The switch setting is shown as follows: Working Interface Channel Channel HSU I2C SPI 1 OFF ON OFF 2 OFF OFF ON We break all the PN532 pins out. The 1.27mm connector hole contains those pins which might not be used for most users. If some developers need to connect those pins, we could supply connectors. www.elechouse.com You could find this product here. Hardware Installation Solder the connector The bended male pins come with the NFC board. Some users might need soldering other types of connectors or directly solder wires on it. Anyway, make sure the wires go across the antenna lines in 90 degree. Connect with Arduino If without the sensor shield, please connect as following: www.elechouse.com Mode Power IIC/I2C Mode HSU Mode SPI Mode PN532 Module VCC GND SDA SCL TXD RXD Arduino UNO Arduino Leonardo Arduino Mega Arduino Due 5V GND Pin 2 /SDA Pin 3/SCL Pin 0 Pin 1 (2560) 5V GND Pin 20 /SDA Pin 21/SCL Pin 19 Pin 18 5V GND Pin 20 /SDA Pin 21/SCL Pin 19 Pin 18 5V GND A4/SDA A5/SCL Pin 0 Pin 1 Could not present message in Serial Monitor on PC SCK MISO MOSI SS Pin 13 or ICSP-3 Pin 12 or ICSP-1 Pin 11 or ICSP-4 Pin 10 ICSP-3 ICSP-1 ICSP-4 Pin 10 Pin 52 or ICSP-3 Pin 50 or ICSP-1 Pin 51 or ICSP-4 Pin 10 ICSP-3 ICSP-1 ICSP-4 Pin 10 Note: SPI on Due is still in developing Arduino UNO only has one serial interface which is also connected to USB port to PC. In HSU mode, the serial monitor could not be used as message displaying windows. Function Test RFID Reader/Writer Here we show how to read and write RFID card with this module. Download the library PN532 at our github page. You could find 4 folders in the library. Unzip the 4 folders at the library folder in Arduino IDE. Start Arduino IDE and choose the example:
