陶晶驰串口屏上如何获取grbl的返回信息 并将x y z a b c各轴坐标显示在对应文本框中编程脚本

要在串口屏上获取 GRBL 的返回信息并将各轴坐标显示在对应的文本框中，您需要在控制器（如 Arduino）上运行一个程序来与 GRBL 进行通信，并将返回的信息传输到串口屏幕上。

以下是一个示例程序，它可以在 Arduino 上运行，并将 GRBL 发送的信息显示在串口屏幕上：

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

void setup() {
  Serial.begin(115200);
  mySerial.begin(9600);
}

void loop() {
  if (mySerial.available()) {
    Serial.write(mySerial.read());
  }
  if (Serial.available()) {
    mySerial.write(Serial.read());
  }
}

该程序使用 SoftwareSerial 库创建一个串口对象，以便将 GRBL 发送的信息传输到串口屏幕上。在 setup 函数中，程序初始化了两个串口的波特率，并在 loop 函数中不断地从两个串口中读取数据，并将其传输到另一个串口中。

接下来，您需要在程序中添加代码，以便将 GRBL 返回的信息解析为坐标，并将其显示在对应的文本框中。下面是一个示例程序，它可以实现这个功能：

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

String axisX, axisY, axisZ, axisA, axisB, axisC;

void setup() {
  Serial.begin(115200);
  mySerial.begin(9600);

  // 设置串口屏幕文本框的初始值
  mySerial.print("t0.txt=\"X:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
  delay(100);
  mySerial.print("t1.txt=\"Y:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
  delay(100);
  mySerial.print("t2.txt=\"Z:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
  delay(100);
  mySerial.print("t3.txt=\"A:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
  delay(100);
  mySerial.print("t4.txt=\"B:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
  delay(100);
  mySerial.print("t5.txt=\"C:0\"");
  mySerial.write(0xff);
  mySerial.write(0xff);
  mySerial.write(0xff);
}

void loop() {
  if (mySerial.available()) {
    char c = mySerial.read();
    if (c == '<') {
      axisX = "";
      axisY = "";
      axisZ = "";
      axisA = "";
      axisB = "";
      axisC = "";
    } else if (c == ',') {
      axisX.trim();
      axisY.trim();
      axisZ.trim();
      axisA.trim();
      axisB.trim();
      axisC.trim();

      mySerial.print("t0.txt=\"X:");
      mySerial.print(axisX);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);

      mySerial.print("t1.txt=\"Y:");
      mySerial.print(axisY);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);

      mySerial.print("t2.txt=\"Z:");
      mySerial.print(axisZ);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);

      mySerial.print("t3.txt=\"A:");
      mySerial.print(axisA);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);

      mySerial.print("t4.txt=\"B:");
      mySerial.print(axisB);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);

      mySerial.print("t5.txt=\"C:");
      mySerial.print(axisC);
      mySerial.print("\"");
      mySerial.write(0xff);
      mySerial.write(0xff);
      mySerial.write(0xff);
      delay(100);
    } else {
      if (c == 'X') {
        axisX = "";
      } else if (c == 'Y') {
        axisY = "";
      } else if (c == 'Z') {
        axisZ = "";
      } else if (c == 'A') {
        axisA = "";
      } else if (c == 'B') {
        axisB = "";
      } else if (c == 'C') {
        axisC = "";
      } else {
        if (axisX.length() < 10) {
          axisX += c;
        } else if (axisY.length() < 10) {
          axisY += c;
        } else if (axisZ.length() < 10) {
          axisZ += c;
        } else if (axisA.length() < 10) {
          axisA += c;
        } else if (axisB.length() < 10) {
          axisB += c;
        } else if (axisC.length() < 10) {
          axisC += c;
        }
      }
    }
    Serial.write(c);
  }
  if (Serial.available()) {
    mySerial.write(Serial.read());
  }
}

该程序在设置初始文本框值后，使用一个状态机来解析 GRBL 返回的信息。当程序接收到 '<' 字符时，它会清空所有轴的值；当程序接收到 ',' 字符时，它会解析所有轴的值，并将其显示在对应的文本框中。在解析过程中，程序将每个轴的值存储在一个字符串变量中，并使用 trim() 函数去掉前导和尾部空格。

请注意，这是一个简单的示例程序，您需要根据自己的需求进行修改和优化。例如，您可能需要添加错误处理代码，以便在 GRBL 返回错误消息时将其显示在串口屏幕上。
