1、iic芯片读写函数void iic_write(unsigned char addr,unsigned char data){ I2CStart(); I2CSendByte(0xa0); I2CWaitAck(); I2CSendByte(addr); I2CWaitAck(); I2CSendByte(data); I2CWaitAck(); I2CStop();}unsigned char iic_read(unsigned char addr){ u

一、原理四个独立按键二、程序key.c//key.c#include<key.h>unsigned char key,key1,key2,key3,key4;定义按键值和四个按键的状态void key_init(){ GPIO_InitTypeDef GPIO_InitStruct; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA,ENABLE); RCC_APB2PeriphClockCmd(RCC_APB2Periph_G

一、原理。。。二、代码//main函数#include "stm32f10x.h"int main(void){ SysTick_Config(72000);//时钟配置，72MHz，1ms进入一次中断 while(1) { } }//服务函数//打开stm32f10x_it.c,在137行左右找到函数 SysTick_Handler() //这就是终端服务函数，void SysTick_Handler(void){}...

一、原理，，，二、代码#include "stm32f10x.h"#include <stdio.h>void Led_Init(void);int main(void){ Led_Init();//初始化led的io口 GPIO_SetBits(GPIOD, GPIO_Pin_2);//打开控制led的锁存器 while (1) { GPIO_ResetBits(GPIOC, GPIO_Pin_8);//将io口置0，即将led点亮 GPIO_Reset
