介绍了一种点位运动控制器的设计，该控制器可以控制步进和伺服电机。该运动控制器以 STM32F103 为主控微处理器，实现了电机起停的加减速控制，扩展了 RS485 串行通信接口，设计了限位保护电 路，移植了嵌入式实时操作系统μC /OS-Ⅱ，通过μC /OS-Ⅱ来调度运动控制器的多个任务，设计了串口通信协议， 可以方便组成多轴控制系统.(Describes the design of a point of the motion controller, the controller can control a stepper and servo motors. The motion controller controlling microprocessor STM32F103, acceleration and deceleration control the motor starts and stops, extended RS485 serial communication interface, designed to limit protection circuits, transplantation of embedded real-time operating system μC/OS-Ⅱ μC/OS-Ⅱ scheduling multiple tasks of the motion controller, designed a serial communication protocol, can easily form a multi-axis control system.)

DEM数据的读入与显示，里面包含了所用的实验数据，调通，代码可以用(DEM data read and display, which contains experimental data used, transferred through, the code can be used)

uvalive4849的ac源码。算法：2-sat。题意：给n（n<=3000）个黑方块的坐标，保证黑方块没有公共边。对于每个黑方块选一个角作为结点，使得所选结点满足输入的一个无向图。其中距离为曼哈顿距离。输出是否有解。possible或impossible。(AC source of uvalive 4849. Algorithms: 2-sat. Meaning of the questions: to n (n <= 3000) coordinates a black box, to ensure that there is no common edge black squares. For each black box to choose a corner as nodes, such that the selected nodes meet a directed graph with no input. Where the distance is the Manhattan distance. Output is solvable. possible or impossible.)
