    That works again. The audio code has been very helpful. I missed this because it was in the output code and my application only uses s/pdif input. I should have looked there, too, though. Thanks for the help!

    So I have my teensy and have made some progress in understanding the registers. However, when I set any of them I get upload errors. The code (which at this point just sends a byte out to a shift register through SPI to...

    Ahhh those names aren't exactly how things are accessed in the code. For example the SPDIFRxLeft Register is read from SPDIF_SRL.

    Thanks. From reading it seems like it should be possible. I've never programmed at this level before, but I'll have a go at it. Time to read up on interrupts.

    It needs to do the operation on every incoming sample (so 44.1k or 48k times per second). So no frames like in normal applications. Latency, as long as it's consistent (jitter < .05 ms), is not a concern, since it can...

    Hello, I work in a neuroscience lab studying the auditory system, and we use TTL trigger pulses to sync our audio stimuli with the EEG system. The way I do this is through simultaneous analog and S/PDIF audio from...
