  /* TIM4 clock enable */
  RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);

/*GPIOA Configuration: TIM4 channel 1 and 2 */   /* GPIOB Configuration PB6 / PB7*/
  GPIO_InitStructure.GPIO_Pin =  GPIO_Pin_6 | GPIO_Pin_7;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOB, &GPIO_InitStructure);

//TIM_DeInit(TIM4);//初始化
TIM_EncoderInterfaceConfig(TIM4, TIM_EncoderMode_TI12,TIM_ICPolarity_Rising, TIM_ICPolarity_Rising);// Configures the encoder mode TI1 for TIM4
/* Enables the TIM2 counter */
TIM_Cmd(TIM4, ENABLE);

//读取角度
TIMCounter = (u32)TIM_GetCounter(TIM4);

只是现在发现,转动快的时候会丢角度.不知道这个玩意支持多块的编码器转动速度.
