各位大侠，有没有用过stm32f030 的编码器模式，为啥不计数呢

已解决，经验分享，有时候遇到解决不了的难题，不妨出去溜达一圈，说不定回来就有惊喜呢！

用过stm8和stm32f1得编码器，感觉很好用啊，但是换成030c8t6就不行了死活不计数，

//TIM_ICInit(TIM1, &TIM_ICInitStructure);
//TIM_ClearFlag(TIM1, TIM_FLAG_Update);
//TIM_ITConfig(TIM3, TIM_IT_Update, ENABLE);

  


//TIM_SetCounter(TIM1, 16);




TIM_Cmd(TIM1, ENABLE);


}

//直接调用以下函数获得计数值
//n_Counter1 = TIM_GetCounter(TIM1);
