STM32F4时钟树简图
//STM32F4 //1.外设时钟使能和失能 HAL库使能某个外设时钟的方法,如: _HAL_RCC_GPIOA_CLK_ENABLE();_/使能GPIOA时钟 HAL_RCC_GPIOA_CLK_DISABLE();/禁止GPIOA时钟 //2.HAL_RCC-OscConfig()函数 HAL_StatusTypeDef HAL_RCC_OscConfig(RCC_OscInitTypeDef*RCC_OscInitStruct) typedef struct { uint32_t OscilatorType;//choose type of oscillator uint32_t HSEState;//State of HSE uint32_t LSEState; uint32_t HSIState; uint32_t HSICablibrationValue;//Calibrated fine-tuned values of HSI uint32_t LSIState; RCC_PLLInitTypeDef PLL; }RCC_OscInitTypeDef; typedef struct { uint32_t PLLState; uint32_t PLLSource; uint32_t PLLM; uint32_t PLLN; uint32_t PLLP; uint32_t PLLQ; }RCC_PLLInitTypeDef;#非技术实习信息共享#
