Connecting PN532 NFC Module to PC using FTDI FT232RL
In this article, we will discuss how to connect a PN532 NFC module to a PC using an FTDI FT232RL USB cable. The PN532 NFC module is a popular choice for NFC-based projects due to its versatility and compatibility with various NFC technologies. The FTDI FT232RL USB cable provides a simple and convenient way to connect the NFC module to a PC.
What is PN532 NFC Module?
The PN532 NFC module is a small and versatile NFC controller that can be used in various NFC-based projects. It supports various NFC technologies, including ISO/IEC 14443A/B, ISO/IEC 15693, FeliCa, and Mifare. It also supports NFC Forum Type 1-4 tags and can act as a reader or a writer.
What is FTDI FT232RL USB Cable?
The FTDI FT232RL USB cable is a USB-to-serial converter cable that provides a simple and convenient way to connect a serial device to a PC. It features an FTDI FT232RL chip that converts the USB signals to serial signals, allowing the PC to communicate with the serial device.
Connecting PN532 NFC Module to PC using FTDI FT232RL USB Cable
To connect the PN532 NFC module to a PC using an FTDI FT232RL USB cable, follow the steps below:
- Connect the FTDI FT232RL USB cable to the PN532 NFC module's SPI interface.
- Connect the FTDI FT232RL USB cable to the PC's USB port.
- Install the FTDI drivers on the PC if they are not already installed.
- Open a serial terminal program on the PC, such as PuTTY or TeraTerm.
- Configure the serial terminal program to the following settings:
- Baud rate: 115200
- Data bits: 8
- Stop bits: 1
- Parity: None
- Flow control: None
- Press the reset button on the PN532 NFC module to establish communication with the PC.
Testing the Connection
To test the connection between the PN532 NFC module and the PC, you can use the following code:
#include <Adafruit\_PN532.h>
#define PN532\_SCK (2)
#define PN532\_MOSI (3)
#define PN532\_SS (4)
#define PN532\_MISO (5)
Adafruit\_PN532 nfc(PN532\_SCK, PN532\_MISO, PN532\_MOSI, PN532\_SS);
void setup() {
Serial.begin(115200);
nfc.begin();
nfc.SAMConfig();
}
void loop() {
String uid = "";
if (nfc.readPassiveTargetID(PN532\_MIFARE\_ISO14443A, &uid[0], uid.length())) {
Serial.println("UID: " + uid);
}
delay(1000);
}
This code uses the Adafruit PN532 library to read the UID of a passive NFC tag. If a tag is detected, the UID is printed to the serial terminal. To use this code, upload it to an Arduino board connected to the PN532 NFC module's SPI interface.
