JVisa whether you can read and write 16-base data?
can you give an example?

[pfroud]

Please give an example of what you want to do

[Rx-out]

send hexadecimal data device

[pfroud]

The string "01 03 00 80 00 07" contains the character 0, then the character 1, then a space character, and so on.

Demonstration:

public static void main(String[] args) {
    printStringBytesInHex("ABCD");
    printStringBytesInHex("01 03 00 80 00 07");
}

private static void printStringBytesInHex(String str) {
    final byte[] bytes = str.getBytes(java.nio.charset.StandardCharsets.US_ASCII);
    for (int i = 0; i < bytes.length; i++) {
        System.out.printf("%02X ", bytes[i]);
    }
    System.out.println();
}

Sample output:

41 42 43 44 
30 31 20 30 33 20 30 30 20 38 30 20 30 30 20 30 37 

Table of ASCII characters:

I will add JVisaInstrument methods to send bytes instead of a string.

It's not what I wanted, thank you! I don't speak English very well and didn't describe the problem clearly! Thank you very much for your reply ,It's a pleasure to communicate with you, can you leave a contact information?

You are welcome!

I added methods to write byte[] instead of String, please test it:

JVisa/src/main/java/xyz/froud/jvisa/JVisaInstrument.java

Line 207 in 7d018d4

public void write(byte[] bytes) throws JVisaException {

Let me know if you need help getting the new code.

[pfroud]

Can you test the new method to write a byte[]?
