Global Timers

A global timer ends an infinite loop when 5 seconds have passed.

Python

from bpod_core.fsm import StateMachine

fsm = StateMachine()

fsm.set_global_timer(
    index=0,
    duration=5,
)

fsm.add_state(
    name='StartGlobalTimer',
    timer=0.25,
    transitions={'Tup': 'Port1Light'},
    actions={'GlobalTimerTrig': 0},
)
fsm.add_state(
    name='Port1Light',
    timer=0.25,
    transitions={
        'Tup': 'Port3Light',
        'GlobalTimer0_End': '>exit',
    },
    actions={'PWM1': 255},
)
fsm.add_state(
    name='Port3Light',
    timer=0.25,
    transitions={
        'Tup': 'Port1Light',
        'GlobalTimer0_End': '>exit',
    },
    actions={'PWM3': 255},
)
