    Ja, etwas. Nicht so gut wie ich moechte! Thank you for the suggestion. It doesn't solve the problem, unfortunately! I'll keep trying. In the meantime, I think that I'll stick with the 3.2 which seems to be...

    Hi Paul. Thank you for the detailed response. That tallies with what I'm finding at this end. I was able to shut the chip down in early testing before I started using the adaptor board. I haven't tried restarting...

    I'm using a WIZ820io adaptor board. I'd like to use the PWDN option because the system is going to be run from a battery. I've cut the trace between the pads on the board but I'm still getting continuity between the ...

    I thought that it would be useful to post some test code on the offchance that someone is able to give me any pointers. This seems to work fine on a Teensy 3.2. These issues are happening on a Teensy 3.6. #define...

    Thanks loads for the info. It's a really useful sanity check. We've wired things up in more or less the same way. I'm still having some really weird problems. I see that you're not using any audio objects and that...

    Hmm, that's interesting. Can I ask how you've connected the WIZ820io and audio shield? Any chance you be able to post the code you're using to initialise everything and set up the audio shield. What clock speed are you...

    I'm now trying to run this on a Teensy 3.6. I'd assumed that it would more or less translate straight over but it doesn't seem so simple. I think that problem is with pin assignment again when audio objects are...

    David_B replied to a thread Audio and Ethernet in Audio Projects
    Glad that you've got it working. Do you mean that you commented the block to effectively remove it and force the library to *not* use SPIFIFPO i.e. change: #if defined(__arm__) && defined(TEENSYDUINO) #include...

    Thanks for the quick reply. I did try that earlier without success but have just again by commenting the line that defines USE_SPIFIFO at the top of the file (doing it properly, I guess) and that seems to work OK :)

    Hi Paul, I've made some progress with this. Using a sine input, I was able to trace things through until I located where it stopped working. I got as far as enable_pins in the SPCRemulation class (around line...

    David_B replied to a thread Audio and Ethernet in Audio Projects
    Thanks for the confirmation, Paul. Great to rule that out. Any ideas about what else might be causing the issue? I've had a look through the Ethernet library to see whether any other pins were being allocated but...

    Hi Paul, Thank you for taking the time to reply. Much appreciated. Think that I've already done that wiring and set the SPI which I do before resetting the WIZ820io and the SD card - unless I've misunderstood ...

    In further investigations - I've found that sending data out over the internal DAC does work - although it's rather noisy (perhaps better electrical layout would help alleviate this) which I guess must mean that...

    Thanks for the swift reply. No, I didn't actually! However the reason for the RaPi isn't to play mp3 specifically, but so that the files can be easily updated by the user over the internet with a trigger via a...

    Hi, I wondered whether anyone might be able to give some guidance on using Teensy to receive audio from a RaPi over i2s. Much of the project is fairly straightforward. I'm using an audio board with a Teensy 3.2 to...
