我尝试通过cube配置HRTIM的同步输出，输出管脚选择PB1，并且在生成的工程中启用了HRTIM，但实际运行测试发现，在PA8管脚上有PWM波形输出，说明HRTIM已正常启动运行，但PB1管脚上没有任何波形，不知是哪里配置的问题，导致没有同步信号输出呢？

Cube生成的HRTIM初始化配置代码如下：

HRTIM_ADCTriggerCfgTypeDef pADCTriggerCfg = {0}; HRTIM_TimeBaseCfgTypeDef pTimeBaseCfg = {0}; HRTIM_TimerCfgTypeDef pTimerCfg = {0}; HRTIM_CompareCfgTypeDef pCompareCfg = {0}; HRTIM_OutputCfgTypeDef pOutputCfg = {0};

目前这里贴的代码，完全没法阅读。论坛这个地方需要完善啊。


其实，你贴cubeMx的配置会更直观点。


我手边一会没找到F334的板，使用STM32G474开发板做了测试验证，可以实现HRTIM的同步输出。


这里提醒下：


1、一定要使能MASTER TIMER；


2、在同步输出那里要选择合适的同步输出触发源，比方可以针对MASTER的比较事件，TIMA的启动或复位事件；


3、你如果选择TIMER的启动和复位事件，如果程序运行过程中没有复位事件，是看不到基于复位事件的同步输出的，但启动事件一般来讲每次运行代码就一个，过了就过了，可能要不停复位才看得到。为了快速验证这个功能，可以先基于master的周期性比较事件来观察同步输出；


4、你HRTIM相关代码没啥问题，即该配置的 该启动都正确无误；
