I do have some trouble to debug the setup of my rotary controller through the expansion.header of my sound card. Documentation of the manufacturer is quite bad, So I am not sure what rpi gpio pins are what pins on the header. So searching for a debug option.. And I am afraid that a multimeter beep ( active resistance measurement ) could damage the 3.3 volt soundcard.
Can we use sbpd to output on pins in human visible frequencies ? and then use a led or multimeter to see where that pin is blinking on the soundcard header? regards M-H Pi based multi-room audio system powered by PiCorePlayer(s): Pi3B with Phat-dac in a Rasptouch, 2 pi B+ with Cirrus Logic Audio Card, Pi Zero with Phat-beat , and a few other tests... ------------------------------------------------------------------------ M-H's Profile: http://forums.slimdevices.com/member.php?userid=66156 View this thread: http://forums.slimdevices.com/showthread.php?t=107001 _______________________________________________ diy mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/diy
