Gravity: UART & I2C NFC Module

1. Getting Started

This guide helps you get started with reading and writing data to S50 NFC cards using an NFC module and Arduino. It covers initial setup, library requirements, and provides sample code for successful NFC communication.

2. Example Code for Arduino-Read Basic Info of NFC Card

This demo runs on the arduino platform. Download this demo to read the basic information of the card, including UID, manufacturer, storage space, RF technology etc. Supported NFC card/tag: MIFARE Classic S50/S70, NTAG213/215/216, MIFARE Ultralight.

3. Example Code for Arduino-Read and Write MIFARE Classic S50 NFC Card with IIC

This demo runs on the arduino platform. Download this demo to learn how to write data to card. We can read the data on the card to see if the write is successful.

4. Example Code for Arduino-Read and Write MIFARE Classic S50 NFC Card with IIC and Interrupt

This demo runs on the arduino uno platform. Download this demo to learn how to read data on card and read data by interrupt. We can read the data on the card to see if the write is successful.

5. Example Code for Arduino-Read and Write MIFARE Classic S50 NFC Card with UART

This demo runs on the Arduino MEGA2560 platform. Download this demo to learn how to read data on card and read data through serial ports. Read the data on the card to see if the write is successful.
