万博网页版登陆页派可以为编码器正交解码并计数吗？

RoAPin = 11
globalCounter = 0
flag = 0
Last_RoB_Status = 0
Current_RoB_Status = 0

def setup():
    GPIO.setmode(GPIO.BOARD)
    GPIO.setup(RoAPin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
    # input mode
    GPIO.setup(RoBPin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
    GPIO.setup(RoCPin, GPIO.IN, pull_up_down=GPIO.PUD_UP)

def rotaryDeal(a):
        global globalCounter
      if GPIO.input(RoBPin):
                globalCounter -= 1
      else:
        globalCounter += 1

def btnISR(channel):
    global globalCounter
    globalCounter = 0

def loop():
    global globalCounter    tmp = 0
    GPIO.add_event_detect(RoCPin, GPIO.RISING, callback=btnISR)
    GPIO.add_event_detect(RoAPin, GPIO.RISING, callback=rotaryDeal)
        while True:
        if abs(tmp - globalCounter) > 10:
            print('globalCounter = %d' % globalCounter)
            tmp = globalCounter

def destroy():
    GPIO.cleanup()
if __name__ == '__main__':
     # Program start from here
    setup()
    try:
        loop()
    except KeyboardInterrupt:
  # When 'Ctrl+C' is pressed, the child program destroy() will be  executed.
        destroy()
编码器转一圈2000个计数，我只能显示100左右，还是转得很慢的情况下
