STM32H7的HRTIM配置输出5组不同频率，不同占空比的波形，同时5组互补输出也是没问题的

eric2013 发表于 2018-8-30 14:52:25

说明：

官方例程：HRTIM_MultiplePWM

我这里对例程做了简单修改，输出不同频率，默认情况下五组都输出的2MHz波形，不同占空比。

每组都可以精确计数脉冲数不？不用内部定时器级联

我估计是不行的。1主5从共6个TIM只管输出pwm

huajin 发表于 2020-4-28 08:50:36

硬汉老师本人新手想问一下这个高分辨率的定时器可以做输出捕获测量频率？有没有例程

dsl1784 发表于 2021-7-14 00:15:03

大佬，我遇到问题了，我试了下HRTIM_TIMERINDEX_TIMER_A ~ HRTIM_TIMERINDEX_TIMER_E只能输出HRTIM_OUTPUT_Tx1输出，HRTIM_OUTPUT_Tx2无法输出。

正常的5个通道都输出的。

回头我试试，你可以使用CubeMX生成个代码先对比下

dsl1784 发表于 2021-7-15 16:33:29

有时间可以研究看下，用Simple的API方便是方便。我后面还是用复杂的Wave方式达成了10路PWM的输出。

好的，HRTIM后面要深入搞下，很多地方还没有去研究挖掘，发挥不了威力。

您好，直接把代码放到main文件中不对，有很多没定义的

那估计是HAL库版本不同造成的。

不是这个问题的话，就是移植有问题了

可以使用HRIM的DMA，这样就可以发任意波形了。
