# Timer Control Example # # This example shows how to use a timer for callbacks. import time from pyb import Pin, Timer # we will receive the timer object when being called # Note: functions that allocate memory are Not allowed in callbacks cnt = 0 def tick(timer): global cnt; cnt +=1 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(2000) print(cnt)

@kidswong999 多谢，问题已解决，前面加sensor.set_hmirror(True)和sensor.set_vflip(True)，然后 将 pan_error 和 tilt_error 算出来的值加个负号就行了
