LED control menu - trippyt - May-31-2018 hi all, im trying to creat a menu on a display-o-tronHAT from pimoroni and would like to create a menu to control a led on and off to start with, im still very new to python and the raspberry pi but im determind to get this working, so far i have: #!/usr/bin/env python import sys import time import dothat.backlight as backlight import dothat.lcd as lcd import dothat.touch as nav from dot3k.menu import Menu, MenuOption from time import sleep # Add the root examples dir so Python can find the plugins sys.path.append('/home/pi/Pimoroni/displayotron/examples') from plugins.clock import Clock from plugins.graph import IPAddress, GraphTemp, GraphCPU, GraphNetSpeed, GraphSysReboot, GraphSysShutdown from plugins.text import Text from plugins.utils import Backlight, Contrast print(""" This advanced example uses the menu framework.

RE: LED control menu - trippyt - May-31-2018 ah i see thank you, that worked but when i go into "Aquarium>Lighting" i can then see >control but cant select it or see the options on or off RE: LED control menu - wavic - May-31-2018 I am not familiar with the modules you are using. However, see the indentation of the Lightcontrol's class code block. RE: LED control menu - trippyt - May-31-2018 i have tried changing the indent but then i get errors saying self is not defined so had to revert back RE: LED control menu - wavic - May-31-2018 What have you tried? Lines 31 to 64 are not properly indented. The definition of the Lightcontrol class starts on line 27 and ends on line 28 RE: LED control menu - trippyt - May-31-2018 This doesnt give me any errors but still can't get past the control menu or see on and off import sys import time import dothat.backlight as backlight import dothat.lcd as lcd import dothat.touch as nav from dot3k.menu import Menu, MenuOption from time import sleep # Add the root examples dir so Python can find the plugins sys.path.append('/home/pi/Pimoroni/displayotron/examples') from plugins.clock import Clock from plugins.graph import IPAddress, GraphTemp, GraphCPU, GraphNetSpeed, GraphSysReboot, GraphSysShutdown from plugins.text import Text from plugins.utils import Backlight, Contrast print(""" This advanced example uses the menu framework.

RE: LED control menu - trippyt - May-31-2018 Becuase i thought you said to do so below, however ive now added MenuOption back to the class but leaving it out of the nested menu so it says Lightcontrol() this also works up to the control submenu, i still cannot see a on or off option (May-31-2018, 06:59 AM)wavic Wrote: Try to changethis is how my code looks now import sys import time import dothat.backlight as backlight import dothat.lcd as lcd import dothat.touch as nav from dot3k.menu import Menu, MenuOption from time import sleep # Add the root examples dir so Python can find the plugins sys.path.append('/home/pi/Pimoroni/displayotron/examples') from plugins.clock import Clock from plugins.graph import IPAddress, GraphTemp, GraphCPU, GraphNetSpeed, GraphSysReboot, GraphSysShutdown from plugins.text import Text from plugins.utils import Backlight, Contrast print(""" This advanced example uses the menu framework.

Look at the class definition. All methods are at the same indentation level as the class statement itself. |
