Hi,

Is it possible to use PCM1864-Based Circular Microphone Board (CMB) Reference Design (TIDA-01454) with OMAP-L138 Development Kit (LCDK) (TMDSLCDK138/6748)?

Best regards,

Adam

    Hi, Adam,

    The Circular Microphone board (CMB) can be used with any host device as it provides access to the I²C control lines and I²S data bus through different connectors. Please refer to the schematic of the CMB to find the available connection points.

    Hi Diego,

    Thank you for your answer. Just one more doubt came to my mind: is there an I²C and an I²S free on the TMDXLCDK138/6748?

    I can see in the schematics that I2C0 is connected to the video codec, and I2C1 is connected to the FTDI chip on both TMDLCDK6748 and on TMDSLCDK138.

    Best regards,

    Adam

    Hi, Adam,

    I am not familiar with the TMDSLCDK138 tool, so I would recommend you to ask to our colleagues of the OMAP forum in e2e for this information.
