So, I tried to implement a simple demo where press of the button controls some other functions of a MoveHub, i.e. changes LED colour, or spins up a motor. The code looks like this:
from pylgbst.hub import MoveHub
from pylgbst import get_connection_bleak
conn = get_connection_bleak()
hub = MoveHub(conn)
def callback_btn(is_pressed):
global hub
print("Btn pressed: %s" % is_pressed)
hub.motor_external.wait_complete()
if is_pressed == 0:
hub.motor_external.timed(5, 1.0, wait_complete=False)
try:
hub.button.subscribe(callback_btn)
time.sleep(60)
finally:
hub.button.unsubscribe(callback_btn)
hub.disconnect()Once I release the button for the first time, it spins up the motor for 5 seconds exactly as I expect it to do. However, it does seem to ignore any further button presses... callback function is not called at all as I am not even getting any strings printed. Is this an expected behaviour due to threaded execution?
Is there a way to implement this?
Thanks a lot in advance.
