2 actions on one button

Hi,

I'm try to play/pause mpc using a momentary push button connected on the gpio.

i guess python would do that nicely but i m just hopeless ....

the code based on other codes I found on the forums is

Code: Select all

import RPi.GPIO as GPIO
import time
import os

GPIO.setmode(GPIO.BCM)
GPIO.setup (17, GPIO.IN)

while True:
   if not GPIO.input(17):
      active = 'pause'
      time.sleep(.1)
      if GPIO.input(17):
         while active == 'pause':
             os.system('mpc pause')
            GPIO.output(12,False)
            if not GPIO.input(17):
               if GPIO.input(17):
                  time.sleep(.1)
                  active = 'pause'
   else:
      GPIO.output(12,True)
       os.system('mpc play')


but of course doesnt work

any advice would be appreciated

Thank you

Have a look at this thread. The programs in the OP do button de-bouncing and edge detection, you may need one or both of these. if you are a python beginner use the non-gui version.

Hi Ken,

thanks for your reply. how do i see the script from the link?
thanks

this seems to work. what do you think? thanks

Code: Select all

import RPi.GPIO as GPIO
import time
import os

GPIO.setmode(GPIO.BCM)
GPIO.setup (17, GPIO.IN)

while True:
    if GPIO.input(17):
      os.system('mpc pause')
      time.sleep(.5)
    if GPIO.input(17):
      os.system('mpc play')
      time.sleep(.5)
