光学仿真

说明：  NFC读写程序NFCDemo，Android平台下官方提供NFC读写的例子程序(NFC reading and writing program NFCDemo, an example program for reading and writing NFC under the Android platform)

说明：  设计一个挂载在 APB 总线上的计数器，按照 APB 的时序给计数器赋值，主 机通过地址对计数器进行配置，通过数据输入端口给计数器设置计数器最大值， 并通过数据输出端口输出计数器的计数值。该设计还设置了一个计数完成信号， 当计数器满足模式配置后的计数要求时，会将该信号拉高(A counter mounted on the APB bus is designed. The counter is assigned according to the sequence of APB The computer configures the counter through the address and sets the maximum value of the counter through the data input port, And output the count value of the counter through the data output port. The design also sets a count completion signal, When the counter meets the counting requirements after the mode configuration, the signal will be pulled high)

可以查看区号,邮编,电话话所在地,有源码哦,数据库很珍贵的,不错(Can view the area code, zip code, telephone words, there are source code, the database is very precious, good)

QQ堂游戏中实现 泡泡追踪的小软件 自己使用说明在内部程序自带中 自己查看(QQ Tang game in a small bubble tracking software for use in their own internal procedures in their view)

装机常用的小软件，不一定最好但一定是最好用的，赶快下吧-Installed capacity of commonly used small software, not necessarily the best but definitely the best use, as soon as possible, are you

用simulink做的机械系统的摩擦模型，机械系统的摩擦模型很实用 ((Mechanical Friction with Simulink and Physical Modeling))

自动关机小程序，可以根据程序是否完成，定义关机的时间(Automatic shutdown program, according to whether the program is completed or not, to define the shutdown time)

说明：  pso in matlab simulink

一种新颖的拓扑结构，四开关BUCK-BOOST变换器，能够实现双向的BUCK功能，BOOST功能，而且能视情况自动切换BUCK和BOOST(A novel topology, four switch buck-boost converter, can achieve two-way BUCK function, BOOST function, and can automatically switch BUCK and BOOST as the case)
