Here is what Bing chat came up with when I asked it to convert your code. I'm pasting it here exactly as it produced it.
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;
import com.fazecast.jSerialComm.SerialPort;
public class Main {
public static void main(String[] args) {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
if (args.length <= 0) {
System.out.println("provide interface as arguments (e.g. /dev/ttyACM0)");
System.exit(0);
}
SerialPort ser = SerialPort.getCommPort(args[0]);
ser.setComPortParameters(115200, 8, 1, 0);
ser.setComPortTimeouts(SerialPort.TIMEOUT_READ_SEMI_BLOCKING, 0, 0);
ser.openPort();
printmenu();
while (true) {
try {
if (System.in.available() > 0) {
int c = reader.read();
if (c == '1') {
System.out.println("--> version");
ser.writeBytes("V\n".getBytes(), 2);
} else if (c == '2') {
System.out.println("\r\n--> start emulation");
ser.writeBytes("C,SETCONF,mdb-addr=0x10\n".getBytes(), 23);
ser.writeBytes("C,SETCONF,mdb-currency-code=0x1756\n".getBytes(), 34);
ser.writeBytes("C,1\n".getBytes(), 4);
} else if (c == '3') {
System.out.println("\r\n--> start with 10");
ser.writeBytes("C,START,10.0\n".getBytes(), 12);
} else if (c == '4') {
System.out.println("\r\n--> vend 0.5");
ser.writeBytes("C,VEND,0.5\n".getBytes(), 10);
} else if (c == '5') {
System.out.println("\r\n--> vend 0");
ser.writeBytes("C,VEND,0\n".getBytes(), 8);
} else if (c == '6') {
System.out.println("\r\n--> stop");
ser.writeBytes("C,0\n".getBytes(), 4);
} else if (c == '0') {
break;
} else {
printmenu();
}
}
while (ser.bytesAvailable() == 0)
Thread.sleep(20);
byte[] readBuffer = new byte[ser.bytesAvailable()];
int numRead = ser.readBytes(readBuffer, readBuffer.length);
System.out.print("\r" + new String(readBuffer));
} catch (Exception e) {
e.printStackTrace();
}
}
ser.closePort();
}
public static void printmenu() {
System.out.println(
"\r\n1-Version 2-subscribe 3-start 4-vend0.5 5-vend0 6-stop 0 to stop\r");
}
}
This code uses the jSerialComm library to handle serial communication. You can add it to your project by including the following dependency in your pom.xml file:
<dependency>
<groupId>com.fazecast</groupId>
<artifactId>jSerialComm</artifactId>
<version>2.7.1</version>
</dependency>
Or you can download the jar file from the jSerialComm website and add it to your project’s build path.
Please note that this code is just an example and may require further modifications to work correctly in your specific use case.
