本程序主要通过外部中断INT0及3.3端口读取PS2键盘值并通过LCD1602显示,键扫描码的解码通过数组方式解码,程序的解码功能主要针对数字及大小写字母和常用标点符号
硬件描述:PS2键盘的时钟线(clk)接89S51的INT0(P3.2),数据线data接(P3.3)
LCD的控制端口分别为: RS = P2^7,RW = P2^6,EP = P2^5,数据端口为P0,液晶显示偏压VL必须接
-This procedure mainly through external interrupt INT0 and 3.3 read PS2 keyboard port value through LCD1602 display, key scan code decoder way through an array of decoding, the procedure for decoding function of the major figures and upper and lower case letters and punctuation marks commonly used hardware description: PS2 keyboard clock line (clk) then 89S51 the INT0 (P3.2), data lines data access (P3.3) LCD control port, respectively: RS = P2 ^ 7, RW = P2 ^ 6, EP = P2 ^ 5, data ports for the P0, LCD bias VL must be received

该时钟以24小时制显示时间,并可显示2000年至2049年之间的任何日期及星期,日期与时间经按键可相互切换,可输入8个闹钟时间设置,每个闹钟设置包括响铃的时间(小时与分钟)、对工作日有效还是对周末有效的标志,以及本项设置是否启用的标志等三部分。这8个闹钟设置均保存在EEPROM中,即使掉电也不用重新输入。-The 24-hour clock to display time, and shows from 2000 to 2049 and any date between the weeks, the date and time as may be mutually switch button, enter the eight alarm time settings, each set including the ringing of an alarm clock Duration (hours and minutes), the effective working days or weekends effective road signs, as well as whether or not to enable this setting, such as a symbol of three parts. This 8 alarm settings are stored in EEPROM, even brown-out do not have to re-enter.
