    Ok. Thanks KurtE. I am also just building one at a time, so I guess I will try just cutting the pins to the correct length.

    Teensy 4.0 header for pins 24-33

    Is there a recommended SMT header for pins 24 to 33 on the Teensy 4.0? I need access to those signals and I already have through-hole headers on the other pins. It seems difficult finding an SMT...

    This problem does not seem to occur when I use I2S2 output, only TDM2 output. I guess I'll have to do some cutting and jumping to swap some signals on my board.

    Could this be related to the other bug that I found with the TDM2 input?

  8. Teensy 4.0 Serial.read fails with AudioOutputTDM2

    Here's a weird problem and so far I haven't found any workaround. I've got the Teensy 4.0 and I can use the Serial.read function to read characters from the USB emulated serial port. However, If I...

    Detect Teensy 4.0 USB serial port

    Is there some way of detecting which serial port is connected to the Teensy 4.0 on a Windows machine? I have the following Matlab code which gives me names for serial port devices. If I plug in an...

    I tried Teensyduino 1.53 and it didn't make a difference. I still had to put AudioOutputI2S first to avoid making AudioInputTDM2 get weird. Well, as long as I have a workaround, I'm good to go, but...

    Ok. I found a way of making it work ok, but I don't understand why it works. I just need to swap the order of AudioInputI2S and AudioOutputI2S in the code above. If I have AudioInputI2S first, the...

    After looking at the discontinuities in the sine wave when AudioInputI2S is uncommented, I notice that they happen every 2.9ms, which is the amount of time in a 128-sample block (i.e....

    So, I tried using Teensy 4.0 OUT1/IN1 for I2S audio and OUT2/IN2 for TDM audio and I am having a problem. The TDM port seems to work fine and the I2S output works fine. However, when I try to enable...
  16. Can Teensy 4.0 use TDM and also have a separate stereo input?

    If the Teensy 4.0 is connected to a CS42448 chip, using the TDM signals to get 48kHz 24-bit audio, how can I get an additional stereo input (also 48kHz) into the system? Are there any additional TDM...
