PN7120 NFC Controller SBC Kit Documentation
The PN7120 NFC Controller SBC Kit is a single-board computer (SBC) designed for Near Field Communication (NFC) applications. It is based on the NXP PN7120 NFC controller, which provides a highly integrated and flexible solution for NFC reader/writer and peer-to-peer communication. This kit is ideal for developing NFC-based projects, such as NFC tag readers, smart posters, and IoT devices.

### Example 1: Reading an NFC Tag using the PN7120 NFC Controller SBC Kit (C Language)
This example demonstrates how to use the PN7120 NFC Controller SBC Kit to read data from an NFC tag using the C language.
Code
```c
#include <pn7120.h>
#include <stdint.h>
#include <string.h>
int main() {
// Initialize the PN7120 NFC controller
pn7120_init();
// Set the NFC mode to reader mode
pn7120_set_mode(PN7120_MODE_READER);
// Wait for an NFC tag to be present
while (!pn7120_check_tag_present()) {
delay_ms(100);
}
// Read the NFC tag data
uint8_t tag_data[256];
uint8_t tag_data_len = 256;
pn7120_read_tag_data(tag_data, &tag_data_len);
// Print the NFC tag data
printf("NFC Tag Data: ");
for (int i = 0; i < tag_data_len; i++) {
printf("%02x ", tag_data[i]);
}
printf("
");
return 0;
}
```
### Example 2: Sending an NFC Message using the PN7120 NFC Controller SBC Kit (Python Language)
This example demonstrates how to use the PN7120 NFC Controller SBC Kit to send an NFC message using the Python language.
Code
```python
import pyserial
import pn7120
# Initialize the PN7120 NFC controller
pn7120.init()
# Set the NFC mode to peer-to-peer mode
pn7120.set_mode(pn7120.MODE_P2P)
# Create an NFC message
message = "Hello, NFC World!"
# Send the NFC message
pn7120.send_message(message)
print("NFC Message Sent!")
# Close the PN7120 NFC controller
pn7120.close()
```
### Example 3: Using the PN7120 NFC Controller SBC Kit with an Arduino Board (Arduino IDE)
This example demonstrates how to use the PN7120 NFC Controller SBC Kit with an Arduino board to read an NFC tag.
Code
```c++
#include <PN7120.h>
void setup() {
Serial.begin(9600);
pn7120.begin();
}
void loop() {
// Check if an NFC tag is present
if (pn7120.tagPresent()) {
// Read the NFC tag data
String tagData = pn7120.readTag();
Serial.print("NFC Tag Data: ");
Serial.println(tagData);
}
delay(1000);
}
```
These examples demonstrate the basic usage of the PN7120 NFC Controller SBC Kit in various contexts. You can modify and expand these examples to suit your specific NFC-based project requirements.
