    SD Socket / Footprint

    I want to integrate the Audio Shield into a custom board.
    Does anybody know what SD socket is used?
    Maybe with a footprint for Target or KiCad?
    Or at best: Is there a PCB layout (Target or KiCad)...
  5. Thank you very much! It is working now!

  6. W25Q128JVSIM not working on Teensy 4.1 but on Audio Shield?

    Hello!
    I soldered a W25Q128JVSIM flash memory onto the Audio shield and it works fine.
    I soldered another one to a Teensy 4.1 and I get "Unable to access SPI Flash chip" from "ReadBenchmark"...

    My solution is to dissect my incoming data into portions <64k. To have a "real" solution FastCRC must be fixed. (At least FastCRC should return an error code if called with a buffersize >= 64k)

    Oh, I think I can answer it by myself. I just looked into the source code of FastCRC. The length parameter for the buffer is of type uint16_t. So it looks like that FastCRC is limited to 64k-1.

    CRC32 error with buffer size>= 64k

    Hello!

    I think the CRC32 library has a bug if the buffer size containing the data is 64k or bigger.

    I wrote a little function in java running on a Linux PC calculating the CRC32 of a dummy data...

    Teensy 4.1: Capture serial break

    Hello!
    Is it possible for a Teensy 4.1 to recognise a serial break sent from the PC side?
    And if yes: How?

    Uwe.

    P.S.: The "PC" side is a PC running a Java program using...
