问 定义了一个常量结构，想用指针的方式使用，不知如何使用？C51中可以定义指针的存储器类型，而MSP的C430中却没有！请高手赐教！谢谢！ 答 1: const uchar string[]={"abcdefghijk\n"};
uchar *pointer;
pointer=&string[]; 答 2: 在C51中：
1）结构定义：
typedef struct _USB_DEVICE_DESCRIPTOR {
UCHAR bLength;
UCHAR bDescriptorType;
USHORT bcdUSB;
UCHAR bDeviceClass;
UCHAR bDeviceSubClass;
UCHAR bDeviceProtocol;
UCHAR bMaxPacketSize0;
USHORT idVendor;
USHORT idProduct;
USHORT bcdDevice;
UCHAR iManufacturer;
UCHAR iProduct;
UCHAR iSerialNumber;
UCHAR bNumConfigurations;
} USB_DEVICE_DESCRIPTOR, *PUSB_DEVICE_DESCRIPTOR;

结构常量：（里边全部是常量）
code USB_DEVICE_DESCRIPTOR DeviceDescr =
{
sizeof(USB_DEVICE_DESCRIPTOR),
USB_DEVICE_DESCRIPTOR_TYPE,
SWAP(0x0110),
USB_CLASS_CODE_TEST_CLASS_DEVICE,
0, 0,
EP0_PACKET_SIZE,
SWAP(0x0471),
SWAP(0x0666),
SWAP(0x0100),
0, 0, 0,
1
};

函数定义：
//发送端点号1建立代码
void code_transmit(unsigned char code * pRomData, unsigned short len)
{
ControlData.wCount = 0;
if(ControlData.wLength > len) ControlData.wLength = len;
ControlData.pData = pRomData;
D12_WriteEndpoint(1, EP0_PACKET_SIZE, ControlData.pData);//发送16字节数据
ControlData.wCount += EP0_PACKET_SIZE;
}
}

函数调用：
code_transmit((unsigned char code *)&DeviceDescr, sizeof(USB_DEVICE_DESCRIPTOR));

请问在MSP的C430中怎么移植？我将以上代码的code改为const编译是通不过的！谢谢赐教！
