Electroniccats_PN7150 API Reference

The Electroniccats_PN7150 class enables Arduino library for I2C access to the PN7150 RFID/Near Field Communication chip.

Class: Electroniccats_PN7150

Include and instantiate the Electroniccats_PN7150 class. Creates a global NFC device interface object, attached to pins 7 (IRQ) and 8 (VEN) and using the default I2C address 0x28

#include <Electroniccats_PN7150.h>

Electroniccats_PN7150 nfc(PN7150_IRQ, PN7150_VEN, PN7150_ADDR);
  • uint8_t PN7150_IRQ: IRQ pin for data interrupt.
  • uint8_t PN7150_VEN: "Reset" or "Enable" pin for device.
  • uint8_t PN7150_ADDR: Hexadecimal address for device, default 0x28 .

Example

#include "Electroniccats_PN7150.h"
#define PN7150_IRQ   (8)
#define PN7150_VEN   (7)
#define PN7150_ADDR  (0x28)

Electroniccats_PN7150 nfc(PN7150_IRQ, PN7150_VEN, PN7150_ADDR); // creates a global NFC device interface object, attached to pins 7 (IRQ) and 8 (VEN) and using the default I2C address 0x28

void setup(){ 
  Serial.begin(115200);
  while(!Serial);
  Serial.println("Detect NFC readers with PN7150");
  uint8_t statusNFC = setupNFC();
  if (!statusNFC) 
    Serial.println("Set up is ok");
  else
    Serial.println("Error while setting up mode, check connections!");
}

int setupNFC(){
  Serial.println("Initializing...");
  int setupOK = nfc.connectNCI();                     //Wake up the board
  if (!setupOK){
    setupOK = nfc.ConfigMode(mode);                   //Set up the configuration mode
    if (!setupOK) setupOK = nfc.StartDiscovery(mode); //NCI Discovery mode
  }
  return setupOK;
}
