从2018年1月开始加#include "reg52.h"int year,month; year=2018; month=0;unsigned char code SMG_duanma[18]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8, 0x80,0x90,0x88,0x83,0xc6,0xa1,0x86,0x8e, 0xbf,0x7f};//012

八个数码管单独依次显示0-9，然后所有数码管同时显示0-f，如此循环#include "reg52.h"unsigned char code SMG_duanma[18]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8, 0x80,0x90,0x88,0x80,0xc6,0xc0,0x86,0x8e, 0xbf,0x7f};void delay(int n){ .

今天学习了，主要是对译码器锁存器的选择有了了解，对以后深入学习有很大帮助。还有，python深入不进去了，这些应该够用。

哎，本来打算认真学的，结果到家之后变得好懒。
