是什么原因造成HAL_TIM_TriggerCallback函数不起作用的呢？

问答对人有帮助，内容完整，我也想知道答案 0 嗨，大家好，我正在研究电机控制，我需要同时设置组合 PWM 和 ADC 触发器同步。最后一种情况是 PWM 工作并且 ADC 被触发，所以当 ADC 被触发时，中断事件正在我放入的 HAL_ADCEx_InjectedConvCpltCallback 中运行 Led Toggle what我看到触发事件在每个 pwm 周期都没有运行。触发事件运行 1 次，没有中断 2 次，然后再次运行中断。如果我要用不同的方式告诉它 --> 运行等待运行等待运行.. . 像那样，我不确定绘图是否正确但可能足够了。而且 HAL_tiM_TriggerCallback 不起作用。 _____-----_-----_______-----_----_______-----_----________-----_----_______- ----_--------___ 脉宽调制 1 ____--------_--------____--------_--------____--------_--------_____- ------_--------____----------------___ 脉宽调制 2 ___--------_--------___--------_--------___--------_---- ----___--------------------___--------_--------___ 脉宽调制 3 - - - - - - -______________________________________________ - - - - - - - - - - - - - - - - - - 引领内部中断下面的代码 //----------------------- tim.c -----------------------// #include "tim.h" extern uint32_t timerPeriod;
