根据上面错误提示，

SyncSocRegs这个符号是在头文件F2837xD_sysctrl.h，已经包含了这个头文件了，为啥还会报错呢？

Seven Han：

请问用的是最新controlsuite中的例程吗？

删掉工程中的IDDK_Servo_2837x_FLASH_lnk_cpu1.cmd文件再编译试下！

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
{floatpi_ref_reg;//电机的给定速度_iqpi_fdb_reg;//电机的反馈速度_iqS_reg;//经过速度PI调节后的速度值_iqS_OutMax;_iqS_Outmin;//速度范围
};
extern volatile struct PISpi_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 PIDpid_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_iqSpeed;//转速标幺值
};
extern volatile struct SPEED_CAPSPEED_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
