dma_m2m_polling#

Overview#

The DMA memory to memory polling example is a simple demonstration program that uses the SDK software. It executes one shot polling transfer from source buffer to destination buffer using the SDK DMA drivers. The purpose of this example is to show how to use the DMA and to provide a simple example for debugging and further development without DMA interrupt.
