mpu6050的一些语法问题

compiling main.c...
..\User\main.c(43): error: #20: identifier "x_temp" is undefined
a=x_temp;
..\User\main.c(44): error: #20: identifier "y_temp" is undefined
b=y_temp;
..\User\main.c(45): error: #20: identifier "z_temp" is undefined
c=z_temp;
最近在弄mpu6050一直这个错误，知道是没定义。但是怎么改还是改不过来。
下面是主函数的代码

[mw_shl_code=c,true]#include "main.h" #include "stdio.h" //????·??ò???????????¨????????????????????????????±??? //?????÷???????????í //extern unsigned int Task_Delay[NumOfTask]; //unsigned int Task_Delay[NumOfTask]={0}; //#define NumOfTask 2 //#define TASK_ENABLE 0 //unsigned int Task_Delay[NumOfTask]; u8 a,b,c; int main(void) { // short Gyro[3]; LED_Configuration(); USART1_Configuration(); IIC_GPIO_Init(); MPU6050_Initialization(); { int i = 0; //delay 500ms?? ????mpu6050???????¨ delay_ms(500); while(MPU6050_Initialization() == 0xff) { i++; //???????????????????????????????????? if(i>10) //?????????????±???????????????????????????????·??·??ù?÷???±?? { while(1) { LED1_TOGGLE(); delay_ms(50); } } else { delay_ms(50); while(1) { MPU6050_Gyro_calibration(); MPU6050_Interrupt_Configuration(); a=x_temp; b=y_temp; c=z_temp; delay_ms(100); printf("???????? %8d%8d%8d ",a,b,c); } } } } [/mw_shl_code]

下面是mpu6050程序

[mw_shl_code=c,true]void MPU6050_Gyro_calibration(void) { u16 i; float x_temp=0,y_temp=0,z_temp=0; for(i=0; i<1000; i++) { MPU6050_ReadData(); delay_ms(1); x_temp=x_temp+MPU6050_Raw_Data.Gyro_X; y_temp=y_temp+MPU6050_Raw_Data.Gyro_Y; z_temp=z_temp+MPU6050_Raw_Data.Gyro_Z; } x_temp=x_temp/1000.00; y_temp=y_temp/1000.00; z_temp=z_temp/1000.00; gyroADC_X_offset=(int)x_temp; gyroADC_Y_offset=(int)y_temp; gyroADC_Z_offset=(int)z_temp;[/mw_shl_code]

求大神指教
