Detailed Description

SDSPI Hardware attributes.

The SDSPI_HWAttrs configuration structure contains the index of the SPI peripheral to be used for data transfers & the index of the GPIO Pin which will act as chip select. This driver uses this information to:

• configure & open the SPI driver instance for data transfers
• select the SD card (via chip select) when performing data transfers

An example configuration structure could look as the following:

const SDSPI_HWAttrs sdspiHWAttrs[1] = {
    {
        // SPI driver index
        .spiIndex = 0,

        //  GPIO driver pin index
        .spiCsGpioIndex = 3
    }
};
