Detailed Description

I2S Hardware attributes.

intPriority is the I2S peripheral's interrupt priority, as defined by the TI-RTOS kernel. This value is passed unmodified to Hwi_create().

pinSD1 and pinSD0 define the SD0 and SD1 data pin mapping, respectively. pinSCK, pinMCLK and pinWS define the SCK, MCLK and WS clock pin mapping, respectively. All these pins are typically defined with a macro in a header file, which maps to an IOID.

A sample structure is shown below:

const I2SCC26XX_HWAttrs i2sHWAttrs[CC26X2R1_LAUNCHXL_I2SCOUNT] = {
    {
       .pinSD1      =  CONFIG_I2S_ADI,
       .pinSD0      =  CONFIG_I2S_ADO,
       .pinSCK      =  CONFIG_I2S_BCLK,
       .pinMCLK     =  CONFIG_I2S_MCLK,
       .pinWS       =  CONFIG_I2S_WCLK,
       .intPriority =  ~0,
    },
};
