QtArduinoSerialPlotter

Arduino Serial Plotter, pyqtgraph

Requirements

• Python 3.8+

Install

pip install PyQt5 pyqtgraph qdarkstyle qtawesome

Run

python qtArduinoSerialPlotter.py

Basic usage

• Only data

    String data ="pltr#["+String(x)+","+String(y)+"]";

• Add label

    String data ="pltr#["+String(x)+","+String(y)+",lbl1]";

• Add Color (#f00)

    String data ="pltr#["+String(x)+","+String(y)+",lbl1,f00]";

• Arduino Example

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

float x=0.0;
char buffer[200];

void loop() {  
  float y=x*x*x;
  y=y/100.0;

  //"pltr#[xValue,yValue,Label]"
  String data="pltr#["+String(x)+","+String(y)+",Lbl1]";
  Serial.println(data);  
  x++;
  
  delay(200);  
  
  while (Serial.available() > 0) {   
    if (Serial.read() == '\n') {      
      Serial.println("ok");    
    }
  }
}

• One graph scene multi line

    String data ="pltr#["+String(x)+","+String(y)+",lbl1:"+String(x)+","+String(y+5)+",lbl2]";

• Multi graph scene multi line

    String data ="pltr#["+String(x)+","+String(y)+",lbl1:"+String(x)+","+String(y+5)+",lbl2]#["+String(x)+","+String(y+20)+",lbl3]";
