简易计算器

STM32驱动的4x4矩阵键盘程序，反转法，很好用的，有学习的可以下载下来看看。(STM32-driven 4x4 matrix keyboard program inversion method, the good, learning can download it and see.)

说明：  里面含有直流电机的PWM波的驱动程序，更有做自动寻线小车程序，可以判断是否要拐弯(Which contains a DC motor PWM wave driver, car and more to do automatic line-tracking program, can determine whether or not to turn a corner)

基于C#的带图层的绘图系统，可完成基本图形的相关绘制，图层的添加与删除，图层的显示与不显示。(With a layer of the C#-based mapping system, the completion of the basic graphics draw, add and delete layers, layers and was not displayed.)

VTK用户手册（VC++版），包含VTK系统架构概述，使用基础，VTK可视化技术，三维体数据，数据接口对象等内容(VTK User s Manual (VC++ edition), including VTK system architecture overview, use foundation, VTK visualization technology, three-dimensional volume data, data interface object, etc.)

说明：  用地层速度，密度等数据对地震资料进行地球物理反演，运用了傅里叶变换求得了子波频谱，反射时间序列等(Geophysical inversion of seismic data is carried out by using the data of formation velocity and density. Wavelet spectrum and reflection time series are obtained by using Fourier transform)

搭建一个有4个部门的公司网络，包含研发部门、测试部门、管理部门和销售部门，利用局域网模型在一个对象中模拟一个服务器和多个客户端的行为(Set up a department of four corporate network, including R & D department, testing department, management department and sales department, the use of local area network model of an object in the simulation at a server and multiple clients of conduct)

基于CCS6.0开发环境，并且基于TMS320F28335平台，一个简单的BUCK闭环程序。 实现了程序的搬移。(Based on CCS6.0 development. and use the TMS320F28335 to achieve a simple buck close-loop program. it also can bring program FLASH to Ram.)

linux下定时器的驱动程序，用于linux下定时器的驱动(linux drivers under the timer, the timer for the driver under linux)

基于USB接口的数据采集卡的设计，使用下位机采集数据通过USB传到上位机软件实时处理和显示波形。提供的资料： 1、优秀、完整毕业论文 2、可运行的上位机软件和上位机源代码 3、下位机硬件设计PCB原理图、制板图、所需的元件（下位机设计很简单， 但很有效） 4、下位机微处理器和数据采集程序 5、答辩PPT 6、中英文文献翻译 提供全部资料，毕业设计无需再做。这是本人大四的毕业设计题目，被评为优秀毕业论文，没有向外发表，并经过四次万方数据库查重，相似度只有3 ！本论文绝对惟一、有保障！ 附件提供了毕业论文主要设计以及上位机软件信息和采集结果。请有意者下载查阅，附件中提供了联系方式，如果论文符合您的要求，请继续和我联系，提供全部资料。(Based on USB interface data acquisition card design, the use of computer data acquisition by USB reached the PC software real-time processing and display waveform.)
