edma4_memory_to_memory#
Overview#
The EDMA memory to memory example is a simple demonstration program that uses the SDK software. It executes one shot transfer from source buffer to destination buffer using the SDK EDMA drivers. The purpose of this example is to show how to use the EDMA and to provide a simple example for debugging and further development.
