Developing the DMA memory-to-memory driver

Create a copy of your previous project in your IDE and rename it DMA_MemToMem. Next, create a new file named dma.c in the Src folder and another file named dma.h in the Inc folder. Update your dma.c file, as shown here:

#include "dma.h"
#define DMA2EN                (1U<<22)
#define DMA_SCR_EN          (1U<<0)
#define DMA_SCR_MINC        (1U<<10)
#define DMA_SCR_PINC        (1U<<9)
#define DMA_SCR_TCIE        (1U<<4)
#define DMA_SCR_TEIE        (1U<<2)
#define DMA_SFCR_DMDIS        (1U<<2)
