基于单片机的无线表决器下位机程序，实现数据的无线传输及和上位机之间的串口通信(Microcontroller-based wireless voting machine computer program under)

说明：  采用Visio Studio编译生成动态链接库，嵌入Psim进行仿真。仿真模型提供了半桥谐振变换器的数模混合仿真，有动态链接库实现PWM的分配。(Visio Studio is used to compile and generate dynamic link libraries, which are embedded in Psim for simulation. The simulation model provides digital-analog hybrid simulation of half-bridge resonant converter, with dynamic link library to realize PWM allocation.)

This program generates the calender of a given month and year, knowing the fact that 1st January 1900 was Monday. The code is simple and well commented.

说明：  一个打开并显示位图或者像素矩阵的程序 注意：本程序没有使用DOC/VIEW架构， 所以理解起来更容易，适合初学者。 本程序支持bmp、raw格式图像的读取(an open and display bitmap pixel matrix, or the procedures to : this procedure does not use DOC/VIEW structure, make it easier to understand and suitable for beginners. This program supports bmp, raw format images read)

实现单片机矩阵键盘的功能的程序，通过实验，程序功能比较完整，可以方便移植(MCU function matrix keyboard program)

GPS time system includes a first portion, a second portion Rinex file read, the third part of the ground EarthFixed receiver position calculation, the fourth part of the pseudo-code based on the baseline solution, the fifth part of the double difference solver)

VC 通过ado技术连接access数据库，实现增删改查(The VC connection access database ado technical CRUD)

此程序主要是为了完成图形的上下左右的移动、缩小和放大。(This procedure is to complete the graphics up and down around Mobile, narrow and amplification.)

段页式存储管理系统：建立一个基本段页存储管理系统的模型。(1-2人) 首先分配一片较大的内存空间，作为程序运行的可用存储空间 建立应用程序的模型，包括分段结构在内 建立进程的基本数据结构及相应算法 建立管理存储空间的基本存储结构。 建立管理段页的基本数据结构与算法。 设计存储空间的分配与回收算法 提供信息转储功能，可将存储信息存入磁盘，也可从磁盘读入 (as above)

（九宫问题）在一个３×３的九宫中有１－８这８个数及一个空格随机的摆放在其中的格子里，如图１－１所示。现在要求实现这个问题：将该九宫格调整为如图１－１右图所示的形式。调整的规则是：每次只能将与空格（上、下、或左、右）相邻的一个数字平移到空格中。试编程实现这一问题的求解。((Nine-palace issues) in a 3 × 3 of the Nine-palace are 1-8 this 8 random number and the placing of a space in which the cell house, as shown in Figure 1-1. Now required to achieve this issue: the squares adjustment for the right as shown in Figure 1-1 form. Adjustment of the rules: each can only be with the spaces (upper and lower, or left, right) adjacent to a digital flat space. Test Programming to solve this problem.)
