Just for reference: There exists a Linux lirc driver module for the Raspberry Pi, named 'lirc_rpi', that does this quite successfully with TSOPxxxx IR receiver connected to a GPIO pin. Conceivably the module could be adapted to work with the Wandboard. I've no idea what kind of load it puts on the processor, nor how much work would be required to adapt the module. I'm not suggesting that it should be pursued. You already seem to have developed a good plan. ------------------------------------------------------------------------ mrw's Profile: http://forums.slimdevices.com/member.php?userid=38299 View this thread: http://forums.slimdevices.com/showthread.php?t=98544 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
