How to use PN532 NFC module?

For using PN532 module, first we will choose the mode of communication between MODULE and CONTROLLER. As mentioned earlier this module has three interfaces, of which we have to choose one. Remember at any given point of time only one of three interfaces can be used. All three cannot be used together. We will have to choose the mode of interface using two switches solder to the board. The switches are S1 and S2 shown in pin diagram.

S1	S2	Interface
OFF	OFF	HSU (High Speed UART)
ON	OFF	I2C
ON	ON	SPI

Choose the mode of interface and corresponding state of switches from above table. Next toggle the switches S1 and S2 to those positions.

After choosing the type of interface, connect the module to the controller or processor. Say if you opted to use I2C, then connect module to I2C of the controller. If you opted to use SPI, then connect module to SPI of controller.

After interfacing you have to download the library files for the module from corresponding websites. Say for ARDUINO platform [https://www.arduinolibraries.info/libraries/adafruit-pn532]. Save the library files in the IDE program files.

Now all that left is to write the program for the controller or ARDUINO in the IDE software. And do call up on the saved library files while writing the program. With those libraries we can directly communicate with the module while skipping all the steps of communication protocol.

Once the programming is done, power up the circuit to get the desired response.
