在C8051F930单片机上，利用端口匹配和PCA实现按键的长按、短按功能。-In the C8051F930 microcontroller, using the port matching and PCA to achieve a long button press, short press functions.

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.
