首先,应该配置芯片的时钟来源——芯片的时钟很重要,根据硬件实际配置时钟来源:打开 System Core 栏目下的RCC,即为芯片时钟配置。 RCC 配置界面。以外部时钟为例,STM32CubeMX中外部时钟配置可选类型为 Disable 、 BYPASS Clock Source(旁路时钟源) 、Crystal/Ceramic Resonator(石英/陶瓷 晶振) 三种类型。参考手册中介...
在System Core下选择RCC选项， 在 RCC mode and Configuration 中的 High Speed Clock(HSE)下选择 ...
2、 将STM32F10x_StdPeriph_Lib_V3.5.0里跟内核相关的几个文件(core_cm3.c/core_cm3.h、startup_stm32f10x_hd.s、stm32f10x.h、system_stm32f10x.c/system_stm32f10x.h)拷贝到CORE文件目录里,几个文件路径如图2、图3、图4所示。 图2
一次搞定,是不是很爽。函数是在core_cm3.h头文件中进行定义的。 1.3 要修改时钟源,比如外部时钟,可以修改SysTick_CLKSourceConfig函数内部,也可按照SysTick_Config 中默认设置FCLK不变。 1.4 要修改中断优先级调用 NVIC_SetPriority函数,函数在core_cm3.h ...
