主要设计制作一个波形发生器，该波形发生器能产生正弦波、方波、三角波和由用户编辑的 特定形状波形 -Main design to produce a waveform generator, the waveform generator can produce sine, square, triangle wave and by the user to edit the specific shape of waveform

设计制作一个任意波形发生器，该波形发生器能产生正弦波、方波、三角波，通过一定的通信方式将用户编辑的任意形状波形数据从PC机传输至微控制器，并从波形生成电路输出所需的波形。波形发生器能够在一定范围内保证恒压输出-Designed by an arbitrary waveform generator, the waveform generator can produce sine, square, triangle wave, through a certain means of communica
