Re: using GPIO46 to detect if monitor is turned on

Apparently not.. I can read from the GPIO, with RPi.GPIO library in python. But when connected (and even when tv is switched off) it's always high. When I switch the tv on, it momentarily pulls the signal low. After reading up on HDMI it behaves as expected. as it is used to either indicate a sink h...

using GPIO46 to detect if monitor is turned on

Hi Is it possible to use GPIO46 (HDMI detect) in a python script to detect if a connected HDMI monitor is turned on? Or is the rpi gpio library limited to the GPIO's available on the pinheader? What I'm thinking about, is sending a "playback stop" command to xbmc/kodi, when the connected monitor is ...

Re: 38kHz modulation with GPIO output??

You could just use what others have done already :)

using the LIRC package, an IR diode on a gpio (with a transistor to beef up current to the diode), and voila..
