原创 STM32高分辨率定时器(HRTIM)使用实例之PWM

STM32高分辨率功能非常强大，寄存器数量非常多，使用起来也比较麻烦，本文使用HRTIM1产生一组互补输出的PWM
高分辨率定时器的初始化比普通定时器要复杂得多，
HRTIM_OutputCfgTypeDef HRTIM_TIM_OutputStructure;//配置输出特性，高低电平等
HRTIM_BaseInitTypeDef HRTIM_BaseInitStructure;//配置基本参数，这部分和普通定时器一样
HRTIM_TimerInitTypeDef HRTIM_TimerInitStructure; //配置不同模式
HRTIM_TimerCfgTypeDef HRTIM_TimerWaveStructure;//配置波形参数，错误等
HRTIM_CompareCfgTypeDef HRTIM_CompareStructure;//配置比较寄存器
用以上几个部分就能产生最简单的PWM波形
HRTIM_DeadTimeCfgTypeDef HRTIM_DeadtimeStructure;//配置死区时间和性质
HRTIM_FaultCfgTypeDef HRTIM_FaultCfgStructure;//配置错误输入
HRTIM_ADCTriggerCfgTypeDef HRTIM_ADCTrigStructure; //配置ADC触发信号
HRTIM_BurstModeCfgTypeDef HRTIM_BurstStructure;//配置Burst模式
等等，还有很多初始化参数和初始化函数，基本分为简单基本功能相关函数，波形相关，输出相关，中断、DMA等模块；
下面的程序用HRTIM产生一组简单的PWM波形，50%占空比，无死区
