Hi,

     Does CC2642R I2S work at master mode? If so then which pins of GPIO need to connect for I2S interface in CC2642R.

    Hi,

    Yes, I2S can be set in master mode on CC2642R. The example i2secho stored in your SDK (examples\rtos\CC26X2R1_LAUNCHXL\drivers\i2secho) shows how to do so.

    The I2S interface requires two clocks: the word clock (WS) and the bit clock (SCK). In addition you can have up to two data lines (SD0 and SD1): each data line can be set to be an input or an output. To finish, the m-clock can be turned on but it is generally not necessary. More details are available in the I2S documentation, in your SDK (docs/tidrivers/doxygen/html/_i2_s_8h.html).

    I hope this will help,

    Best regards,
