一、实验任务 利用开发系统编制程序，产生三角波、锯齿波、正弦波 二、程序编制要求 分别产生三种波形，并能通过按键调节输出频率 三、改变频率的方法 改变数据送入0832的延时，即通过延时子程序的参数改变实现。延时参数的改变即通过键功能选择，用查表法将表格中的延时参数送入延时子程序。 四、程序设计提示 　　1、功能键应设四个：{ 2、功能键的选择： 采用转换设计法时，应选用键值连续的按键-genert

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.
