class nonblocking_timer.NonBlockingTimer(interval=-1)

Non blocking timer class for use with CircuitPython

get_interval()

Get interval

next()

Returns true or false according to the following algorithm: if interval <= 0 raise RuntimeError if status != RUNNING raise RuntimeError if time.monotonic() - start_time > interval return True and set start_time = time.monotonic() else return False

set_interval(seconds)

Set the trigger interval time in seconds (float). If interval <= 0 raise a RuntimeError

start()

Sets status to RUNNING. Sets start_time to time.monotonic(). Call next() repeatedly to determine if the timer has been triggered. If interval <= 0 raise a RuntimeError

status

Get Status

stop()

Sets status to STOPPED. Do any cleanup here such as releasing pins, etc. Call start() to restart. Does not reset start_time.
