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

利用步进电机实现上水的模拟仿真…
采用步进电机模拟洗衣机电机，实现上水、浸泡、洗涤、漂洗、甩干等过程。洗涤分弱洗、轻洗、强洗；可设定3级水位设定，每级水位均设定水位下限（值自定）；可选择漂洗次数（3~5次）。使用键盘进行流程及参数设定及自动存储流程，设定暂停键，可暂时停止洗衣机的工作，恢复后按原设定程序继续进行，同时设定停止键，可终止洗衣机的工作，并在LED或LCD上显示当前流程。-Simulation using stepper motors washing machine motor to achieve Sheung Shui, soaking, washing, rinsing, drying and other processes. Washing sub-weak wash, light wash, strong wash can be set to three water level settings, set the water level in each grade level were lower (the value of self-set) optional rinsing times (3 ~ 5 times). Using the keyboard processes and parameter settings and automatic memory processes, set pause button to temporarily suspend the work of washing machines and restore original settings after the process to continue at the same time set the stop button, may terminate the work of washing machines, and LED or the LCD displays the current process.
