xmshao 回答时间: 2023-08-25 22:18:48就你的问题，我这边找了G474的开发板做了测试，起初也碰到了你说的问题。 刚开始怀疑是库驱动方面的问题搞错方向而 耽误了点时间，后来发现 还是我用户代码方面有些问题。 我这里使用的TIMA的两路输出。用户代码如下： HAL_HRTIM_WaveformCountStart(&hhrtim1, HRTIM_TIMERID_TIMER_A); HAL_HRTIM_WaveformOutputStart(&hhrtim1 , HRTIM_OUTPUT_TA1); HAL_HRTIM_WaveformOutputStart(&hhrtim1 , HRTIM_OUTPUT_TA2); 最终结构就是两路50%占空比的pwm输出，至于同相还是反相我们可以自住设定。 有关CubeMx的配置我会单独附件出来供参考。
