基于AVR單片機的帶密碼顯示的DS302仿真設計

1、廣州白云技師學院 電子系 技師班單片機技術課程項目化教學系列基于AVR單片機（ATMEGE16A）的帶密碼顯示的DS302仿真設計 廖高靈功能：1、開機密碼123456用戶可以根據(jù)自己需求修改 2、進入時鐘界面通過K1,K2,K3調(diào)整時鐘仿真界面：程序代碼：（已經(jīng)通過調(diào)試）/*main_1302.c*/#include<iom16v.h>#include<macros.h>#include"1602_jp_sz.c"#include"1302_sz.c"#include"keyboard.c"#include&
