老师您好，我的也出现了这种情况，我用的是TI网站上下载的F2812的例程，在这个例程的基础上改的，
struct PIS
{
float pi_ref_reg;//电机的给定速度
_iq pi_fdb_reg;//电机的反馈速度
_iq S_reg;//经过速度PI调节后的速度值
_iq S_OutMax;
_iq S_Outmin;//速度范围
};
extern volatile struct PIS pi_Sdc;/*速度PI调节器的输入输出值*/
struct PID
{
_iq Kp;
_iq Ki;
_iq Kd;
_iq OutMax;
_iq Outmin;
};
extern volatile struct PID pid_spd;/*速度PI调节器的参数*/
//速度计算结构体
struct SPEED_CAP
{
float EventPeriod;//捕获的时间间隔
float SpeedScaler;//转换到标幺值的预定标
Uint32 BaseRpm;//转速基值
Uint32 SpeedRpm;//转速实际值
_iq Speed;//转速标幺值
};
extern volatile struct SPEED_CAP SPEED_CAP_handle;
extern Uint16 SPEED_REF;
extern _iq S_Inte;
extern Uint16 SPEED_COUNT;
extern float Sdc_Set;
//extern Uint16 Capt;//霍尔信号的状态
extern Uint16 T2_PR;//通用定时器T2的周期寄存器值
extern Uint16 i;//捕获中断的记数点
extern Uint32 duty;//占空比
extern int m;
#endif
在上面报错的变量和结构体都已经在DSP28_GlobalVariable.h中定义了，而且DSP28_GlobalVariable.h也在已经声明了，怎么还会出现这种错误？
还麻烦老师指导。谢谢老师
