额   编码器接口没配置，直接初始化了，，， 下面是初始化函数
void Encoder_Configuration(void)
{
 TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
 TIM_ICInitTypeDef TIM_ICInitStructure;

 

 RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);

 

 

 TIM_DeInit(TIM1);
 TIM_TimeBaseStructInit(&TIM_TimeBaseStructure);

 

 TIM_TimeBaseStructure.TIM_Prescaler = 1; // No prescaling
 TIM_TimeBaseStructure.TIM_Period = 65535;
 TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
 TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;  
 TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);
 
 TIM_EncoderInterfaceConfig(TIM1, TIM_EncoderMode_TI2,
                              TIM_ICPolarity_Rising, TIM_ICPolarity_Rising);
 TIM_ICStructInit(&TIM_ICInitStructure);
 TIM_ICInitStructure.TIM_ICFilter =6   ;//;TIM_ICFilter_Mask  6

 TIM_ICInit(TIM1, &TIM_ICInitStructure);
 
 // Clear all pending interrupts
 TIM_ClearFlag(TIM1, TIM_FLAG_Update);
 TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE);
 //Reset counter
 TIM1->CNT = T1_Register_val;
 
 TIM_Cmd(TIM1, ENABLE);
}

编码器的码值不对，相应的零位也不对了，，，

0位与码值无关

楼主你好 你是直接把编码器接到stm32的引脚吗
