I have three PiCorePlayers, two Logitech Boom players and two Logitech Radios all working from a Squeezeplug running on a Raspberry Pi B. One of the PiCorePlayers is connected to a 2 x 300Watt (RMS into 8 Ohms) amplifier that runs my single zone whole house sound system. This whole system is in the (well ventilated) top of a closet.
I switch it on and off via the Android Squeezebox app. I built a little bit of electronics that senses sound coming out of the Pi + Behringer UCA-222 USB interface. Once it senses a signal, it operates a mains relay that turns on the amp. It stays on until about 2 minutes after the signal stops. So far it has been very reliable. However it would be very nice if a Raspberry PI GPIO pin could change state when the PiCorePlayer (the Pi is always powered on and ready) is switched on via the Android app. This is analogous to powering on a Boom via the same app and seeing the screen light up. If I could use this positive On/Off signal to activate my relay then I could dispense with my signal sensor. Why? Mrs. rederikus sometimes turns the things down so low that if it is activated later with a quiet piece of music then, sometimes it does not activate. Mrs. rederikus then complains to me that it does not work. OK, I could always play only very loud music but, I like Pink Floyd a lot and some bits are just quiet. If anybody knows of a GPIO pin that toggles when PiCorePlayer is activated (not powered up) I would be most grateful. Thanks in advance. ------------------------------------------------------------------------ rederikus's Profile: http://forums.slimdevices.com/member.php?userid=63042 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
