Windows 10 contains new APIs for accessing GPIO, I2C, SPI, and UART directly from usermode. Using the Adafruit NFC Shield with I2C The Adafruit NFC shield is designed to be used using the I2C by default. I2C only uses two pins (Analog 4 and 5 which are fixed in hardware and cannot be changed) to communicate and one pin as an 'interrupt' pin (Digital 2 - can be changed however).I am a new user of fritzing and I haven’t found a part for RFID RC522 so I took me a whole day to make this part which includes downloading INKSCAPE, learning it, Learning How to make custom parts in fritzing newer version as the workflow has been drastically changed then the older versions.
