You are absolutely correct. I wish to refresh data.On "button to restart program":
That doesn't appear to be what you want. It appears what you want is a button to trigger a manual update of the data.I've been trying something like this. The sleep function is used to make the script repeat itself every 15 minutes. I have been trying to do this but the sleep function just hangs everything until it is done it's 15 minutes. I'm trying different things to get around it, but hit a snag with importing an installed module within a virtual environment (mentioned in another post on this topic).I can think of a few ways, but I'd put the code that does the updating into a function (without the sleep) . I'd then have the button press call that function. gpiozero's button class makes this easy to do.
You might want to take an event driven approach rather than a traditional linear one and instead of a sleep use a timer with a callback function.
An untested noddy example:
Code:
import gpiozeroimport signalimport threadingdef do_stuff(): print('doing some stuff') def do_timed_stuff(): print('timer fired') t.cancel() # just to be sure t.start() do_stuff() # after the timer restart to minimise driftbtn = gpiozero.Button(2)btn.when_pressed = do_stufft = threading.timer(15 * 60, do_timed_stuff)t.start()do_stuff()signal.pause() # this pauses your main program so nothing will happen until one of the callbacks fires.I know you did, and it is fantastic and helpful. Thank you for it, and your help!*: Full disclosure - I wrote that.
Thanks.
