一款模拟正弦波，方波等函数的波形发生器。设置好起始频率、结束频率以及周期即可开始演示波形曲线。你可以调整采样、缓冲，增益调节，振荡器等参数进行修正。这个代码附带的几个控件不错，有点像工控组件，如旋钮，开关，LED显示-A simulated sine wave, square wave function, such as the waveform generator. Set up the starting frequency, ending frequency, and waveform pr

数码管的数字显示，基于fpga的控制，方便学习和参考-LED digital display, fpga-based control, facilitate learning and reference
