    BMP581 I3C Not Working

    BMP581 I3C Not Working

    Hi,
    I can get BMP581 to work with I2C and SPI, but not I3C.
    Attached is the screenshot for sending a SETDASA command.
    It returned NACK for static address.
    The static address is 0x46.
    I am using SparkFun Pressure Sensor - BMP581 (Qwiic).
    What do I missed?

    Thanks.

    Hi choongay,

    Could we know which host platform you used?
    And what's about your software code?

    I am using LabVIEW FPGA to regenerate the I3C signal in my project.

    Do you able to screenshot an I3C signal on BMP581 so that I can regenerate the signal?

    Thanks.

    Hi choongay,

    Unfortunately, we are not familiar with FPGA.
    BMP581 is a standard I3C slave device that will work as long as the master I3C device meets normal communication timing.

    Hi

    Is there any command I need to send before I can send SETDASA command?

    Is the screenshot attached above got the SETDASA command right?

    The screenshot shows BMP581 replied ACK to 0x7E but not the static address.
