        The micro controller has the DMA documentation and examples of implementations.

         

        SDIO and SPI interfaces uses DMA to transfer data. Take a look at wwd_bus.c for dma usages for SDIO and SPI interfaces.

         

        For SDK-2.4.1:

        Wiced\Platform\common\ARM_Cortex_M4\STM32F4xx\SDIO\wwd_bus.c

        Wiced\Platform\common\ARM_Cortex_M4\STM32F4xx\SPI\wwd_bus.c

        Implementation for other MCUs could also be found in Wiced\Platform\common\ directory.

         

        For SDK-3.0.0:

        WICED\platform\MCU\STM32F4xx\WWD\wwd_SDIO.c

        WICED\platform\MCU\STM32F4xx\WWD\wwd_SPI.c

        Implementation for other MCUs could also be found in WICED\platform\MCU\ directory.
