```c
void HAL_TIM_Base_MspInit(TIM_HandleTypeDef* htim_base)
{  
    ADVANCED_TIM_RCC_CLK_ENABLE();

HAL_NVIC_SetPriority(ADVANCE_TIM_IRQn , 0, 2);
    HAL_NVIC_EnableIRQ(ADVANCE_TIM_IRQn );  
}

void TIM_Mode_Config(void)
{
	TIM_ClockConfigTypeDef sClockSourceConfig;
  TIM_MasterConfigTypeDef sMasterConfig;
  
  TIM_TimeBaseStructure.Instance = ADVANCED_TIMx;

TIM_TimeBaseStructure.Init.Prescaler = ADVANCED_TIM_PRESCALER;

TIM_TimeBaseStructure.Init.CounterMode = TIM_COUNTERMODE_UP;

TIM_TimeBaseStructure.Init.Period = ADVANCED_TIM_PERIOD;

TIM_TimeBaseStructure.Init.ClockDivision=TIM_CLOCKDIVISION_DIV1;

TIM_TimeBaseStructure.Init.RepetitionCounter = ADVANCED_TIM_REPETITIONCOUNTER;

HAL_TIM_Base_Init(&TIM_TimeBaseStructure);

sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL;
  
  HAL_TIM_ConfigClockSource(&TIM_TimeBaseStructure, &sClockSourceConfig);

sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
  sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
  
  HAL_TIMEx_MasterConfigSynchronization(&TIM_TimeBaseStructure, &sMasterConfig);
  
  HAL_TIM_Base_Start_IT(&TIM_TimeBaseStructure);

}

TIM_HandleTypeDef TIM_TimeBaseStructure;
void  ADVANCE_TIM_IRQHandler (void)
{
	HAL_TIM_IRQHandler(&TIM_TimeBaseStructure);	 	
}

void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
 // time1++;
}
