# Timer Control Example
|
|
#
|
|
# This example shows how to use a timer for callbacks.
|
|
|
|
import time
|
|
from pyb import LED
|
|
from pyb import Timer
|
|
|
|
blue_led = LED(3)
|
|
|
|
|
|
# we will receive the timer object when being called
|
|
# Note: functions that allocate memory are Not allowed in callbacks
|
|
def tick(timer):
|
|
blue_led.toggle()
|
|
|
|
|
|
tim = Timer(2, freq=1) # create a timer object using timer 2 - trigger at 1Hz
|
|
tim.callback(tick) # set the callback to our tick function
|
|

while True:

time.sleep_ms(1000)
