基于stm32f1系列的rtc萬年歷設(shè)計(jì)源碼

ID:434410 · 發(fā)表于 2018-11-27 18:49

包括整個(gè)工程源碼，我用的是正點(diǎn)原子f103zet6的板子；如果板子不同，或者自己焊接的話只需改下相關(guān)的io口，一般只要改key.c,led.c，的初始化函數(shù)就可以了
如有不懂的地方，請(qǐng)聯(lián)系我解答

單片機(jī)源程序如下:

#include "led.h"
#include "delay.h"
#include "sys.h"
#include "usart.h"
#include "lcd.h"
#include "usmart.h"
#include "rtc.h"
#include "key.h"

delay_init(); //延時(shí)函數(shù)初始化
uart_init(9600); //串口初始化為9600
LED_Init(); //初始化與LED連接的硬件接口
LCD_Init(); //初始化LCD
KEY_Init();
usmart_dev.init(72); //初始化USMART
