本人研究方向是高频开关电源，之前实验室所用的控制器都是DSP28335，其主频仅有150M，相对于1M的开关频率，分辨率太低了。后来发现专门为高频电源设计的STM32G474系列单片机，虽然主频仅有170M，但其高精度定时器（HRTIM）的时钟频率可倍频至5.44GHz，即184ps的分辨率，非常适合于高频开关电源应用。本文将分享STM32G474RxT系列的高精度定时器的寄存器配置与使用。
为了方便计算，宏定义了HRTIM时钟频率，单位为kHz。
#define HRTimerCloclk 5440000?为了方便管理，新建一个HRTIM.c的文件。其中包含HRTIM的初始化函数和HRTIMA的中断服务函数。
HRTIM初始化函数实现了各模块的初始化和ADC触发的功能。

}?可操作相应的寄存器实现改变频率变化与占空比，以及触发ADC的时刻。
/*-----------更新周期寄存器-----------*/

/*-----------更改比较寄存器值，改变占空比-----------*/

/*-----------用于触发ADC采样-----------*/
