请解释一下这两行代码RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

这两行代码是在STM32芯片上配置时钟的代码。

`RCC_OscInitTypeDef RCC_OscInitStruct = {0};` 是定义一个结构体变量 `RCC_OscInitTypeDef`，该结构体用于配置STM32的内部振荡器和PLL。在这里，我们将变量初始化为0，以确保所有成员都是默认值。

`RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};` 是定义一个结构体变量 `RCC_ClkInitTypeDef`，该结构体用于配置系统时钟。在这里，我们将变量初始化为0，以确保所有成员都是默认值。

这两个结构体变量将用于配置STM32芯片的时钟系统，包括选择内部振荡器或外部晶体振荡器、配置PLL和分频器等。具体来说，`RCC_OscInitTypeDef`结构体用于配置STM32的振荡器和PLL，而`RCC_ClkInitTypeDef`结构体用于配置系统时钟的分频器和时钟源。

RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};

These two lines of code declare two structures, RCC_OscInitTypeDef and RCC_ClkInitTypeDef, and initialize them to zero.

RCC_OscInitTypeDef is used to configure the system clock source and its parameters, such as the PLL (Phase-Locked Loop) multiplication factor, the HSE (High-Speed External) crystal frequency, and the HSI (High-Speed Internal) oscillator frequency.

RCC_ClkInitTypeDef is used to configure the system clock frequency and its peripherals, such as the AHB (Advanced High-Performance Bus) and APB (Advanced Peripheral Bus) buses, and their respective prescalers.

Both structures are used in the initialization of the system clock and its peripherals in embedded systems that use the STM32 microcontroller.
