把systick中断程序屏蔽后（相当于不进入systick中断），实验结果没改善。调用 LL_RCC ......
时钟的选择由时钟配置寄存器(RCC_CFGR)中的MCO[2:0]位控制。 RCC_MCOConfig(RCC_MCO); 参数RCC_MCO为要输出的内部时钟: RCC_MCO_NoClock --- 无时钟输出 RCC_MCO_SYSCLK --- 输出系统时钟(SysCLK) RCC_MCO_HSI --- 输出内部高速8MHz的RC振荡器的时钟(HSI) RCC_MCO_HSE --- 输出高速外部时钟信号(...

MCO and CSS configuration functions A set of macros are defined in stm32f3xx_hal_rcc.h andstm32f3xx_hal_rcc_ex.h. They allow executing elementary operations on RCC block registers, such as peripherals clock gating/reset control: __PPP_CLK_ENABLE/__PPP_CLK_DISABLE to enable/disable the ...
当HSI被用于作为PLL时钟的输入时,系统时钟能得到的最大频率是64MHZ。 STM3210X_RCC.H头文件,主要是对RCC相关的寄存器进行了一个重新的定义命名以及对.c文件中的函数进行申明。 可以从参考手册的6.3 RCC寄存器描述了解到。更加详细的内容 /***
