hallo allerseits.
ich taste mich zur zeit ganz langsam an den zero und python ran. Mein momentanes wissen reicht dazu folgenden code halbwegs zu verstehen, ihn über vnc und geany zu starten (das fliegermodell) und zu beenden (der rote punkt).
Code:

from RPLCD.i2c import CharLCD
from gpiozero import Motor, OutputDevice
from time import sleep
from gpiozero import Button
lcd = CharLCD('PCF8574', 0x3f)
pin_a_HL = Button(19,pull_up=True) # Rotary encoder pin A connected to GPIO19
pin_b_HL = Button(26,pull_up=True) # Rotary encoder pin B connected to GPIO26
def pin_a_HL_rising(): # Pin A event handler
if pin_b_HL.is_pressed: print("-1") # pin A rising while A is active is a clockwise turn
def pin_b_HL_rising(): # Pin B event handler
if pin_a_HL.is_pressed: print("1") # pin B rising while A is active is a clockwise turn
#pin_a_HL.when_pressed = pin_a_HL_rising # Register the event handler for pin A
#pin_b_HL.when_pressed = pin_b_HL_rising # Register the event handler for pin B

lcd.write_string('schiebe links')
sleep(2)
def schiebe_rechts():
lcd.clear()
motor_VL.forward(0.5)
motor_VR.backward(0.5)
motor_HR.forward(0.5)
motor_HL.backward(0.5)
lcd.write_string('schiebe rechts')
sleep(2)
def ende():
lcd.clear()
lcd.write_string('stop')
sleep(2)
lcd.clear()
while True:
vorwaerts()
rueckwaerts()
drehe_links()
drehe_rechts()
schiebe_links()
schiebe_rechts()
ende()
beim beenden des codes drehen sich manchmal zwei, manchmal aber auch drei oder eines der vier räder einfach weiter. Wie verhindere ich das ohne den zero ab- und wieder anzuschalten? Das booten ist sehr lästig...
