MISRA compliance

UM0324

96/105

5.2.2

MISRA rule deviations

The only rule not respected in the AC IM IFOC software library is:

Rule number 45: “Type casting from any type to or from pointers shall not be used.”

This deviation occurs in the 75x_svpwm_3shunt.c module, and it is due to the definition

of the DMA_InitTypeDef type in the 75x_dma.h header file:

typedef struct

{

u32 DMA_SRCBaseAddr;

u32 DMA_DSTBaseAddr;

u16 DMA_BufferSize;

u16 DMA_SRC;

u16 DMA_DST;

u16 DMA_SRCSize;

u16 DMA_SRCBurst;

u16 DMA_DSTSize;

u16 DMA_Mode;

u16 DMA_M2M;

u16 DMA_DIR;

}DMA_InitTypeDef;

Basically, the DMA_SRCBaseAddr and DMA_DSTBaseAddr fields which must contain

memory addresses should have been declared as pointers instead of unsigned 32bit.
