我有一小段代码检测我的树莓特定GPIO上的事件。当检测到事件时,如果在函数中我只保留“print('Flash…'),则调用名为increase\u counter的函数我每个事件只有一次打印,但是如果我用urllib2调用一个url,整个increase\u计数器将执行两次,因此我将有2次闪烁计数
import RPi.GPIO as GPIO
import time
import urllib2,json
def increase_counter(ch):
print('Flash ... ')
requete='http://192.168.1.20:8080/json.htm?type=command¶m=udevice&idx=52&svalue=1'
response=urllib2.urlopen(requete)
data = json.loads(response.read())
print data
IRPIN = 4
GPIO.setmode(GPIO.BCM) #GPIO SETUP
GPIO.setup(IRPIN,GPIO.IN) #GPIO SETUP
GPIO.add_event_detect(IRPIN, GPIO.FALLING, callback=increase_counter, bouncetime=3) #Calling event when flash is detected
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
print(' Stopped !!!')
except:
print(' Stopped !!!')
raise
finally:
GPIO.remove_event_detect(IRPIN)
GPIO.cleanup(IRPIN) # GPIO cleanup
