想问一下，为什么每个声明语句都有报错

要加分行符

extern void vW25Q32_Init(SPI_ObjectTypedef * hSPIx, \
uint8_t uSCL_Port, \
uint8_t uSCL_Pin, \
uint8_t uMOSI_Port, \
uint8_t uMOSI_Pin, \
uint8_t uMISO_Port, \
uint8_t uMISO_Pin, \
uint8_t uCS_Port, \
uint8_t uCS_Pin);

这种#define不太好，inline更好一些。比如：
#define SPI_SCL_1(_HANDLE_) ( GPIO_WritePin((_HANDLE_)->uSCL_Port, (_HANDLE_)->uSCL_Pin, 1))
我会写成：
inline void SPI_SCL_1(_HANDLE_) { GPIO_WritePin((_HANDLE_)->uSCL_Port, (_HANDLE_)->uSCL_Pin, 1))}

不过虽然编译器都支持inline，但是这并不是c语言标准关键字，要查编译器手册才可以。
