我的ARM编程技巧—堆集

跟着学习的深化，逐渐发现，编程时更多的作业是不断的装备寄存器，做着许多重复的作业。所以就感觉很有必要把常常运用的寄存器、装备结构罗列出来，以方便运用！！这是其间的一部分，其他的慢慢来

本页所包括的装备函数有：
void SysTick_Configuration(void)；
void GPIO_Configuration(void)；
void EXTI_Configuration(void)；
void NVIC_Configuration(void)；
void RCC_Configuration(void)；
void IWDG_Configuration(void)；

//一起需求装备的结构体变量
GPIO_InitTypeDef GPIO_InitStructure;
EXTI_InitTypeDef EXTI_InitStructure;
NVIC_InitTypeDef NVIC_InitStructure;

*******//Cortex体系定时器（SysTick）*********************
*******************************************************

void SysTick_Configuration(void)
{
/
//挑选体系定时器（SysTick）的时钟源
SysTick_CLKSourceConfig(SysTick_CLKSource_HCLK);


SysTick_SetReload(72000);

SysTick_ITConfig(ENABLE);
}
*********///GPIO的装备程序***************************************

GPIO_Init(GPIOC, &GPIO_InitStructure);


GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
GPIO_Init(GPIOB, &GPIO_InitStructure);
}
//中止线路初始化
void EXTI_Configuration(void)
{
