    Hello,

    I'm using the SGTL Audio boards as a logger, I have no need for the headphone jacks and I'm in a tight space.

  4. Including any file in Audio library causes entire Audio library to be included

    Hello,

    My project leverages STL5000 audio shields and I sample audio data. I included the files I need from the audio library for i2S , the shields, and patchCords without including the whole...

    Please help :eek:!,

    I can't figure out why my "SpiSdLogDisk" library and "TetraAudio" library won't compile if they are both in the same project.

    TetraAudio includes: ...
  6. How can I include the SdFat that came with Audio.h (not the default one)

    Hello,

    I have an audio 'logger', and I want to use an SD2Card object in my sketch.

    Audio.h does (in a round about way) provide the SD2Card code but only the library seems to see it. This is...

    Thanks, I took a look at your SDLLL (templates! nice) and then pulled down SdFat to try a build. Then I noticed it's not really for the 3.2 (__MKL26Z64__) but for 3.5's and 3.6's (__MK64FX512__...

  9. Save file to SD in a different thread (or use interrupts for sampling?)?

    Hello,

    I see a lot about playing quad-audio with the sparkfun teensy quad-audio solution, but not much on recording quadio (quad-audio?).

    Using polling, it doesn't seem possible to record...

    Hello,

    Yes, use the L & R through holes (you can see them labeled on the underside of the board) on the SGTL-5000. The mics also need a ground, you can use the two grounds next to the R & L if you...
