複数のwxpython静的テキストをmcp3008のデータで表示し、動的に更新する方法は？

Question

私はmcp3008と雨水センサーからデータを取るpythonプログラムを持っています。私はwxpythonを使ってguiに表示したいと思っています。これは私のセンサープログラムです：

import spidev 
from time import sleep 
import os 

spi = spidev.SpiDev() 
spi.open(0,0) 

def getAdc (channel): 
    if ((channel>7)or(channel<0)): 
     return -1 

    r = spi.xfer2([1, (8+channel) << 4, 0]) 

    adcOut = ((r[1]&3) << 8) + r[2] 
    percent = int(round(adcOut/10.24)) 
    volts = ((adcOut/1023) * 5) 
    if adcOut >= 0 and adcOut <= 300: 
      print "--------------------------------------------------------------" 
      print ("ADC Output:  {0:4d} Percentage: {1:3}% Voltage : {2} V".format(adcOut,percent,volts)) 
      print ("Rain Condition : Heavy Rain") 
      sleep(5) 

    elif adcOut >= 0 and adcOut <= 500: 
      print "--------------------------------------------------------------" 
      print ("ADC Output:  {0:4d} Percentage: {1:3}% Voltage : {2} V".format(adcOut,percent,volts)) 
      print ("Rain Condition : Moderate Rain") 
      sleep(5) 

    elif adcOut >= 0 and adcOut <= 700: 
      print "--------------------------------------------------------------" 
      print ("ADC Output:  {0:4d} Percentage: {1:3}% Voltage : {2} V".format(adcOut,percent,volts)) 
      print ("Rain Condition : Light Rain") 
      sleep(5) 

    else : 
      print "--------------------------------------------------------------" 
      print ("ADC Output:  {0:4d} Percentage: {1:3}% Voltage : {2} V".format(adcOut,percent,volts)) 
      print ("Rain Condition : No Rain") 
      sleep(5) 
while True: 
    getAdc(0) 

ここに私のwxpythonプログラムを作成して表示します。 2つのプログラムを1つに結合してデータを表示する方法を教えてください。この後

import datetime 

global current_time 
current_time = datetime.datetime.strftime(datetime.datetime.now(), '%d-%m-%y %H:%M:%S') 

try: 
    import wx 
except ImportError: 
    raise ImportError, "The wxPython module is required to run this program." 

class RainSensorApp_wx(wx.Frame): 
    def __init__(self, parent, id, title): 
     wx.Frame.__init__(self, parent, id, size = (500, 300)) 
     self.SetBackgroundColour(wx.BLUE) 
     self.parent = parent 
     self.initialize() 

    def initialize(self): 
     sizer = wx.GridBagSizer() 
     font = wx.Font(20, wx.DECORATIVE, wx.ITALIC, wx.NORMAL) 
     self.SetFont(font) 

     self.label = wx.StaticText(self, -1, label = u'Rain Sensor Level: {0:4d} Percentage:  {1:3}% Voltage: {2} V'.format(adcOut, percent, volts)) 
     self.label.SetBackgroundColour(wx.BLUE) 
     self.label.SetForegroundColour(wx.WHITE) 
     sizer.Add(self.label, (1,0), (1,2), wx.EXPAND) 

     self.label = wx.StaticText(self, -1, label = u'Rain Condition: {}'.format(rain_condition)) 
     self.label.SetBackgroundColour(wx.BLUE) 
     self.label.SetForegroundColour(wx.WHITE) 
     sizer.Add(self.label, (2,0), (1,3), wx.EXPAND) 

     self.label = wx.StaticText(self, -1, label = u'Time Updated: {}'.format(current_time)) 
     self.label.SetBackgroundColour(wx.BLUE) 
     self.label.SetForegroundColour(wx.WHITE) 
     sizer.Add(self.label, (3,0), (1,4), wx.EXPAND) 

     self.SetSizer(sizer) 
     self.Show(True) 

    def on_timer(self): 
     wx.CallLater(1000, self.on_timer) 

if __name__ == "__main__": 
    app = wx.App() 
    frame = RainSensorApp_wx(None, -1, 'Rain Sensor Monitor') 
    app.Mainloop() 
    getAdc(0) 

私はちょうど昨日、それを学ぶように動的複数wxPythonの静的テキストを更新するCallLaterを使用して、タイマーを追加します。私は誰が私を助け、私のポストを読むことに感謝します。

私はspidevビットをエミュレートする必要がありますが、これはちょっとしたハックですが、これはあなたを起動させるのに十分なはずです。
コードは重要であると思うところで文書化されています。

import datetime 
#import spidev 
from time import sleep 
import os 

#spi = spidev.SpiDev() 
#spi.open(0,0) 
#Setup some variables as I don't have spidev 
global adcOut 
adcOut = 200 
percent = int(round(adcOut/10.24)) 
volts = ((adcOut/1023) * 5) 
rain_condition="none"
