无刷电机资料，经典的电机的速度PID控制程序，极其好，找了好久找到的。...

实现二值化，当像素值（r+g+b）/3>128时设为255,当像素值小于128时设置为0.做归一化处理后，2值化的颜色 1为白，0为黑。边缘部分，计算有误差，255,254,253,252 就算白，0，1，2，3，4就算黑。屏幕显示时，肉眼是分辨不出这点误差的。你可以对2值化后的图像值作归一化处理，得到1和0，然后再放大（乘255），就可得到满意的数值。至于左边界上 1 254 253， 0 255 255，可能是2值化前，颜色原本就有差别。不是2值化的错误。

程序中一开始已初始化一个需要求的阶乘数字 程序只需要运行就可得到结果,如要修改,可在源代码作一个小小修改即可-a process has begun to request the initialization of a number of factorial procedure can only be run, to changes in the source code for a small change can be

游戏规则 目的：在本游戏中，你将作为一名裁缝，将尽可能多的纽扣穿成 一个闭合的路线。游戏初始有 15 个纽扣，随着时间的增 加，纽扣数目也增加，当达到70个时游戏即结束。 规则：只能在有纽扣的点穿线，且只能在水平方向或竖直方向穿 线。线可交叉，但有纽扣的点不能交叉连接。 秘诀：要尽可能使连线长且该连线上的纽扣数多。-Rules of the game Objective: In this game, you will serve as a tailor, will be wearing buttons as much as possible into a closed line. The initial game there are 15 buttons, as time increases, the number of buttons has also increased, when the reach 70, when the game to an end. Rules: only point in a button threading, and only in the horizontal direction or vertical direction of threading. Line to cross, but the point can not be cross-connect button. Tip: To the extent possible, to connect the connection on a long and a few more buttons.
