STM32-F103 TIM1不能用

不知道干什麼我的TIM1用不了

,同樣的設置TIM2,3,4都可以用，以下是我的code,請各位指點一下。

#define ENCODER_TIMER   TIM1 // Encoder unit connected to TIM1
#define ENCODER_TIM_PERIOD (u16) 10000   // number of pulses per revolution
#define TIMx_Channel TIM1_UP_IRQn//TIM4_IRQn    //Timer channel
#define TIMx_PRE_EMPTION_PRIORITY 0
#define TIMx_SUB_PRIORITY 1
