Code Examples

### Example 1:BV30 with Arduino (RS232 Interface)

In this example, we'll connect the BV30 to an Arduino board using the RS232 interface. We'll demonstrate how to read the bill acceptor's status and retrieve the inserted bill value.

Hardware Requirements:

Arduino Board (e.g., Arduino Uno)
 BV30 Compact Bill Acceptor
 RS232 cable
 Power supply (12V DC, 1A)

Software Requirements:

Arduino IDE (version 1.8.x or later)

Code:
```c++
#include <SoftwareSerial.h>

// BV30 RS232 interface pins
#define BV30_RX 2
#define BV30_TX 3

SoftwareSerial bv30Serial(BV30_RX, BV30_TX);

void setup() {
  Serial.begin(9600);
  bv30Serial.begin(9600);
}

void loop() {
  // Read BV30 status
  bv30Serial.write(0x02); // Send ENQ command (inquiry)
  delay(50);
  char buffer[10];
  bv30Serial.readBytes(buffer, 10);
  Serial.print("BV30 Status: ");
  Serial.println(buffer);

// Check if a bill is inserted
  if (buffer[0] == 'I') {
    // Read bill value
    bv30Serial.write(0x03); // Send EOT command (end of transmission)
    delay(50);
    bv30Serial.readBytes(buffer, 10);
    Serial.print("Bill Value: ");
    Serial.println(buffer);
  }
  delay(1000);
}
```
### Example 2:BV30 with Raspberry Pi (USB Interface)

In this example, we'll connect the BV30 to a Raspberry Pi using the USB interface. We'll demonstrate how to read the bill acceptor's status and retrieve the inserted bill value using Python.

Hardware Requirements:

Raspberry Pi (e.g., Raspberry Pi 4)
 BV30 Compact Bill Acceptor
 USB cable
 Power supply (12V DC, 1A)

Software Requirements:

Raspbian OS (version 10 or later)
 Python 3.x

Code:
```python
import serial

# Open the USB serial connection to the BV30
ser = serial.Serial('/dev/ttyUSB0', 9600)

while True:
    # Read BV30 status
    ser.write(b'x02')  # Send ENQ command (inquiry)
    response = ser.read(10)
    print("BV30 Status:", response.decode())

# Check if a bill is inserted
    if response[0] == b'I':
        # Read bill value
        ser.write(b'x03')  # Send EOT command (end of transmission)
        response = ser.read(10)
        print("Bill Value:", response.decode())
    time.sleep(1)
```
### Example 3:BV30 with ESP32 (Pulse Output Interface)

In this example, we'll connect the BV30 to an ESP32 board using the Pulse output interface. We'll demonstrate how to read the bill acceptor's status and count the inserted bills.

Hardware Requirements:

ESP32 board (e.g., ESP32 DevKitC)
 BV30 Compact Bill Acceptor
 Pulse output cable
 Power supply (12V DC, 1A)

Software Requirements:

ESP32 Arduino Core (version 1.0.6 or later)

Code:
```c++
#include <Arduino.h>

// BV30 Pulse output pin
#define BV30_PULSE 18

volatile int billCount = 0;

void setup() {
  Serial.begin(9600);
  pinMode(BV30_PULSE, INPUT);
}

void loop() {
  // Read BV30 status
  if (digitalRead(BV30_PULSE) == HIGH) {
    billCount++;
    Serial.print("Bill inserted! Count: ");
    Serial.println(billCount);
    delay(100);
  }
}
```
These code examples demonstrate how to interface with the BV30 Compact Bill Acceptor using different communication interfaces and programming languages. By following these examples, you can integrate the BV30 into your IoT projects, enabling cash payment capabilities for various applications.
