Square waveform, triangle waveform and arbitrary waveform may be obtained by modifying the look-up table.
通过修改数据表可以产生方波、三角波或其他任意波形信号。
The waveform square wave, sine wave, triangle wave and the sawtooth wave, etc.
其波形有方波、正弦波、三角波和锯齿波等。
If the programs are slightly changed, any waveform can be generated and output, such as triangle wave, square wave and zigzag wave, etc.
程序稍作修改还能生成并输出任意波形，如三角波、方波、锯齿波等。
Design requirements: (1) can output sawtooth, triangle wave, sine wave, pulse wave. (2) according to the keyboard command to switch between waveforms. (3) can adjust the output waveform frequency.
设计要求：(1)能够输出锯齿波，三角波，正弦波，脉冲波。(2)能根据键盘命令进行波形之间的切换。(3)能对输出的波形频率进行调节。
