问题描述

我在构建是使用Python通过一个简单的GUI通过互联网发送控制消息的远程控制的机器人的过程

I am in the process of building a robot that is remote controlled using Python to send control messages via the Internet through a simple GUI.

我已经得到我的code工作pretty的一部分很好，图形用户界面和控制系统，但我坚持。我试图用一个视差平传感器从到对象的信息的距离，该值发送给我的Python脚本控制要显示在远程GUI。

I have gotten part of my code working pretty well, the GUI and control systems, but I am stuck. I am trying to use a parallax ping sensor to get distance to objects information from an Arduino Mega, and send that value to my Python control script to be displayed on the remote GUI.

这是我遇到的主要问题是如何整合Python的code将使用已经建立的COM端口与Arduino的和发送消息，告诉Arduino的轮询平传感器，然后发送到一个Python程序将获得的价值，然后让我插入值到我的GUI。

The main problem that I am having is how to integrate Python code that will use the already established COM port with the Arduino and send a message to tell the Arduino to poll the ping sensor and then send to a Python program which will receive the value, and then let me insert that value into my GUI.

我已经有这个code控制Arduino的，和它的作品，我的简单的GUI。

I already have this code to control the Arduino, and it works, with my simple GUI.

import serial
ser = serial.Serial('/dev/ttyUSB0', 9600)

from PythonCard import model

class MainWindow(model.Background):
    def on_SpdBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
    def on_FBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
       ser.write('@')
       ser.write('F')
       ser.write(chr(spd))
    def on_BBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
       ser.write('@')
       ser.write('B')
       ser.write(chr(spd))
    def on_LBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
       ser.write('@')
       ser.write('L')
       ser.write(chr(spd))
    def on_RBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
       ser.write('@')
       ser.write('R')
       ser.write(chr(spd))
    def on_SBtn_mouseClick(self, event):
       spd = self.components.SpdSpin.value
       ser.write('@')
       ser.write('S')
       ser.write('0')
    def on_PngDisBtn_mouseClick(self, event):
       ser.write('~')
       ser.write('P1')
       ser.write('p2')

app = model.Application(MainWindow)
app.MainLoop()

我真的很想做的是改进上述code和添加一个按钮点击来告诉Python将消息发送到Arduino检查平传感器和返回值。
我非常识字与Arduino的code，但我刚开始在过去两周与Python玩。

What I would really like to do is improve the above code and add a button to click to tell Python to send a message to the Arduino to check the ping sensor and return the value.I am very literate with the Arduino code, but I just started playing with Python in the last two weeks.
