关于stm32f334 hrtim的PWM输出
新手刚接触，一个人琢磨了半天还是没有PWM出来，只能跑论坛上来求助了，恳请哪位大神帮忙指点一下，万分感谢啊:'(。附上用cubeMX生成的初始化代码：

引脚配置好了吗？可以先试下用高级/通用定时器输出PWM，成功了再换HRTIM，这个东西功能强大用起来也麻烦 GPIO配置应该没有问题，现在是定时器在跑，但是PWM就是没有输出，看了下寄存器，输出使能这个寄存器上TB1OEN、TB2OEN这两个位还是0，就是置不了位，求指点:( 高分辨率定时器，没用过，有空得试一下看有什么特色 解决了吗？我的也是一样的问题，CUBE设置好了，怎么弄都没有输出 qiuyuqiang001 发表于 2018-8-17 19:08
