lpc_dma_wrap_transfer#
Overview#
The DMA wrap transfer example is a simple demonstration program that uses the SDK software. It executes two burst 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 wrap feature and to provide a simple example for debugging and further development.
