dds_test
直接数字式频率合成器DDS设计、Verilog。
产生的信号可以是正弦波或方波、三角波、锯齿波等,自选。
采用DDS技术,将所需生成的波形写入ROM中,按照相位累加原理合成任意波形。
此方案得到的波形稳定,精度高,产生波形频率范围大,容易产生高频。
本实验在设计的模块中,包含以下功能:
(1)通过 freq 信号输入需要的频率的值;
(2)通过 wave_sel 信号选择所需的波形;
(3)通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog.
The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional.
By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation.
The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform.
This experiment includes the following functions in the designed module:
(1) Input the required frequency value through freq signal;
(2) Choosing the required waveform by wave_sel signal;
(3) Select the multiplier of waveform amplification by amp_adj signal.)

微信小程序UI 上拉加载 下拉刷新的实现
微信小程序UI设计实例,今天分享给大家的是上拉加载 下拉刷新,这个功能在微信中还是比较常见的,大家也习惯了操作时候下拉屏幕刷新内容,上拉则加载更多内容,这个功能在Android智能机上已经得到了很好的应用,这个例子就是教大家如何在微信的小程序中实现上拉加载内容,下接刷新内容的功能。
注:可能这个小程序代码还有些Bug需要修正,仅供参考。
