memdma_engine.c

用DSP BF533直接读写操作硬盘的源代码！源代码中有头文件指示了硬盘如何和BF533开发办接口

#include ".\h_file\system.h"

extern ushort desc_array_S0[21];
extern ushort desc_array_D0[21];

memDMA_engine()
{
	*pMDMA_S0_CURR_DESC_PTR = desc_array_S0;
	*pMDMA_D0_CURR_DESC_PTR = desc_array_D0;
	*pMDMA_S0_CONFIG = Array_S_Config;
	*pMDMA_D0_CONFIG = Array_D_Config_1;
}
