好的,这里为您提供一段processing的交互代码,供参考:
```
import processing.serial.*;
Serial myPort;
void setup() {
size(400, 400);
println("Available serial ports:");
println(Serial.list());
// Set the data rate for the serial port
myPort = new Serial(this, Serial.list()[0], 9600);
}
void draw() {
background(255);
fill(0);
textSize(20);
text("Enter a command:", 50, 50);
// Wait for user input
while (myPort.available() == 0) {
// Do nothing
}
// Read the input from the serial port
String input = myPort.readStringUntil('\n');
// Process the input
if (input != null) {
input = trim(input);
// Print the input on the screen
text(input, 50, 100);
// Write a response back to the serial port
myPort.write("You said: " + input + "\n");
// Wait for the response to be sent
delay(100);
}
}
```
这段代码演示了一个简单的Processing交互程序。它等待用户输入,然后通过串行端口将输入发送到另一个设备。它还读取来自串行端口的响应,并在屏幕上打印出来。你可以根据需要修改这段代码,以满足你的具体应用需求。
