利用51单片机设计波形显示器完成以下功能：
1.能产生至少三种波形。
2.采用按键独立显示波形。
3.在LCD显示波形图案及其各项基本参数。
4.能同时显示两种波形。
5.波形参数可调。(We use the 51 microcontroller to design the waveform display to accomplish the following functions.
1. can produce at least three kinds of waveforms.
2. use the key to display the waveform independently.
3., display the waveform pattern and its basic parameters in LCD.
4. can display two kinds of waveforms at the same time.
5. waveform parameters are adjustable.)
