STM32F上的计时器

我正在尝试使用HAL库在STM32F板上设置通用计时器。到目前为止,这是我的专长:

static TIM_HandleTypeDef s_TimerInstance = { 
    .Instance = TIM2
};

void InitializeTimer() {   
    __TIM2_CLK_ENABLE();  
    s_TimerInstance.Init.Prescaler = 40000;  
    s_TimerInstance.Init.CounterMode = TIM_COUNTERMODE_UP;  
    s_TimerInstance.Init.Period = 500;  
    s_TimerInstance.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;  
    s_TimerInstance.Init.RepetitionCounter = 0;  
    HAL_TIM_Base_Init(&s_TimerInstance);  
    HAL_TIM_Base_Start(&s_TimerInstance); 
}

我无法访问s_TimerInstance的成员。

  

字段'Init'无法解析

包含的头文件如下:

#include "stm32f0xx_hal.h"
#include "stm32f072xb.h"
#include "stm32f0xx_hal_tim.h"

TIM_HandleTypeDef的定义如下:

typedef struct
{
  TIM_TypeDef              *Instance;     /*!< Register base address             */
  TIM_Base_InitTypeDef     Init;          /*!< TIM Time Base required parameters */
  HAL_TIM_ActiveChannel    Channel;       /*!< Active channel                    */
  DMA_HandleTypeDef        *hdma[7];      /*!< DMA Handlers array
                                             This array is accessed by a @ref TIM_DMA_Handle_index */
  HAL_LockTypeDef          Lock;          /*!< Locking object                    */
  __IO HAL_TIM_StateTypeDef   State;         /*!< TIM operation state               */
}TIM_HandleTypeDef;
