Source: https://github.com/gassajor000/pn532pi/blob/master/README.md

Install the library using pip. This is the first step to using the library.

```bash
pip install pn532pi
```

--------------------------------

### Configure PN532 for SPI Interface

Source: https://github.com/gassajor000/pn532pi/blob/master/README.md

Configure the PN532 object for SPI communication. This example shows how to set the SPI interface and slave select pin.

```python
# Set the desired interface to True
SPI = True
I2C = False
HSU = False

... 
if SPI:
    PN532_SPI = Pn532Spi(Pn532Spi.SS0_GPIO8)
    nfc = Pn532(PN532_SPI)
```

--------------------------------

### Initialize PN532 with I2C Interface

Source: https://github.com/gassajor000/pn532pi/blob/master/README.md

Initialize the PN532 object using the I2C interface. This code snippet shows the basic setup for I2C communication.

```python
from pn532pi import Pn532I2c, Pn532

i2c = Pn532I2c(1)
nfc = Pn532(i2c)

def setup():
    nfc.begin()
    # ...
```
