    Those are very helpful - thanks for posting!

    I use the following to read the status register from the CS42448. Maybe you'll find them useful :)

    The additional character is \r or 0x0D, of course, so if you are just expecting \n line terminations you'll get too many characters. Just in case some day in the future someone comes looking :)

    Some information about accessing the port with tytools and teensy_serialmon here:

    Tytools works from the CLI. If...
  4. Talking to the Audio device serial HID port

    When using the USB Audio device, a HID object with VID 16C0 and PID 04D2 is created in place of a standard serial port. Is there any direction on how to go about communicating with this HID port in...

    I don't know if you've solved this problem, but I've found with my board I must include:
    cs42448.volume(1); or the 42448 stays silent. Very unlikely do to the .enable returning false in your case...

    Thanks. I'd been doing that incorrectly for a very long time and it had worked - leading me to believe I was doing it right. I appreciate the correction!

    CMSIS RFFT works on 1.48, broken on 1.53?

    Working on a Teensy 4.0, Windows 10 (2 different machines)
    I made a copy of my Arduino 1.8.9 directory and installed 1.53 over 1.48 in one instance.
    Opened some code I've been working on in 1.53...

    Yep. It's the 10uF cap in the passive input filter. Here's an electrolytic vs a COG. My fail and probably what those with the OSH Park board are seeing given I used its BOM as a design reference....

    That looks great! I find it interesting that you split the ground planes across the CS42448.

    Do you have your MCLK running straight from the Teensy to the codec or are you doing anything to...

    No worries. It's a lot of attenuation and quite unexpected.



    According to the datasheet, the highpass filter is -3dB at 1 Hz. The measurement device is an M-Audio Mobile Pre and though the...

    Thank you for the reply. I was reading that thread earlier today and it seems an interesting direction with many possibilities for I/O.

    I recognize that the codec has DC offset filters, but that...

    Custom TDM board - what did I do wrong?

    I created a test audio board for a T4 project that isn't acting exactly as expected.

    This test board is modeled after Paul's OSH Park CS42448 multichannel TDM board. I followed the passive input...
