STM32F030C8T6模板
时钟都在system_stm32f0xxx.里设定。用那个开那个，输出都是48MHZ，最大频率，可以在里面改变大小频率
#define PLL_SOURCE_HSI // HSI (~8MHz) used to clock the PLL, and the PLL is used as system clock source(~ 8MHz)
//#define PLL_SOURCE_HSE // HSE (8MHz) used to clock the PLL, and the PLL is used as system clock source
//#define PLL_SOURCE_HSE_BYPASS // HSE bypassed with an external clock (8MHz, coming from ST-Link) used to clock
使用内部时钟 48MHZ
