我有一个python程序，它从mcp3008和雨水传感器获取数据。我想用wxpython在gui中显示它。这是我的传感器程序：
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)
这是我创建的wxpython程序来显示它。帮助我如何将两个程序合二为一，以显示数据。
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)
在此之后我会使用CallLater添加计时器来动态更新多个wxpython静态文本，因为我昨天才学会它。我很感激谁能帮助我并阅读我的帖子。

这有点像黑客，因为我必须模仿spidev位，但这应该足以让你开始。
代码记录在我认为重要的地方。

#import spidev
from time import sleep
import os
#spi = spidev.SpiDev()
#spi.open(0,0)
#Setup some variables as I don't have spidev

adcOut = 200
percent = int(round(adcOut/10.24))
