Wie zu verbinden 2 Python-Dateien & kivy

Question

Ich versuche, 2 Python-Dateien (eine mit einer Kivy-Datei) zu kombinieren.

So wie kombiniere ich diese (joystick.py)

import time 

# Import SPI library (for hardware SPI) and MCP3008 library. 
import Adafruit_GPIO.SPI as SPI 
import Adafruit_MCP3008 

# Import MQTT 
import paho.mqtt.client as mqtt 


# Select robot to control 
#currentRobot = "quad" 
currentRobot = "kvakke" 
#currentRobot = "turret" 
#currentRobot = "dalek" 

# COnfig the mqtt 
mqttc = mqtt.Client() 
mqttc.connect("piMote.local", 1883) #10.13.37.60 
mqttc.publish("piMote/" + currentRobot, "piMote joysticks is online") 
mqttc.loop(2) #timeout = 2s 

# Hardware SPI configuration: 
SPI_PORT = 0 
SPI_DEVICE = 0 
mcp = Adafruit_MCP3008.MCP3008(spi=SPI.SpiDev(SPI_PORT, SPI_DEVICE)) 

deadBand = 100 

# Remapping the joystick value 
# return (x_value - in_min) * (out_max - out_min)/(in_max - in_min) + out_min 
def remap(mapValue, in_min, in_max, out_min, out_max): 
    if mapValue < 512 - deadBand: 
     return((mapValue - in_min) * (out_max - out_min)/(in_max - in_min) + out_min) 
    elif mapValue > 512 + deadBand: 
     return((mapValue - in_min) * (out_max - out_min)/(in_max - in_min) + out_min) 
    else: 
     return(0) 

print('Reading MCP3008 values, press Ctrl-C to quit...') 

class joystickControl(): 
    def update(self): 
     # Read all the ADC channel values in a list. 
     values = [0]*8 
     for i in range(8): 
      # The read_adc function will get the value of the specified channel (0-7). 
      values[i] = mcp.read_adc(i) 

     # return (x_value - in_min) * (out_max - out_min)/(in_max - in_min) + out_min 
     print(remap(values[0], 0, 1024, -255, 255) , remap(values[1], 0, 1024, -255, 255)) 

     # Publish the joystick values 
     mqttc.publish("piMote/" + currentRobot + "/leftX", remap(values[0], 0, 1024, -255, 255)) 
     mqttc.publish("piMote/" + currentRobot + "/leftY", remap(values[1], 0, 1024, -255, 255)) 
     mqttc.publish("piMote/" + currentRobot + "/leftZ", remap(values[2], 0, 1024, -255, 255)) 

     mqttc.publish("piMote/" + currentRobot + "/rightX", remap(values[3], 0, 1024, -255, 255)) 
     mqttc.publish("piMote/" + currentRobot + "/rightY", remap(values[4], 0, 1024, -255, 255)) 
     mqttc.publish("piMote/" + currentRobot + "/rightZ", remap(values[5], 0, 1024, -255, 255)) 

     # Pause for half a second. 
     time.sleep(0.5) 

joystickControl = joystickControl 


while True: 
    joystickControl().update() 

mit diesem (main.py)

import kivy 
kivy.require("1.9.0") 

import time 
import paho.mqtt.client as mqtt 

from kivy.app import App 
from kivy.uix.gridlayout import GridLayout 
from kivy.lang import Builder 

# Select robot to control 
#currentRobot = "quad" 
currentRobot = "kvakke" 
#currentRobot = "turret" 
#currentRobot = "dalek" 

mqttc = mqtt.Client() 
mqttc.connect("piMote.local", 1883) #10.13.37.60 
mqttc.publish("piMote/"+ currentRobot, "piMote buttons is online") 
mqttc.loop(2) #timeout = 2s 

class piMoteGridLayout(GridLayout): 
    def callback(self, instance): 
     mqttc.publish("piMote/" + currentRobot +"/button", instance) 
     time.sleep(0.1) 

class piMoteApp(App): 
    def build(self): 
     return piMoteGridLayout() 

piMoteApp = piMoteApp 

if __name__ == '__main__': 
    piMoteApp().run() 

und es dann mit diesem (piMote.kv) funktioniert

Versuchen Sie so.

Ich kann Ihren Code nicht testen, da ich den Mikrocontroller und Joystik nicht habe. Aber das wird dir vielleicht eine Idee geben, wie es gemacht werden kann.
