超宽频室内定位_STM32与DWM1000模块通信定位精度达10cm

在定时器控制下反复的裁减一幅图像和改变其大小(timer under the control of the repeated cuts an image and change its size)

实现弧度向角度的转换，判断在第几象限。。。。。。(Realize the conversion of radian to angle and judge the quadrant)

水和水蒸气性质，按照IAPWS-IF97的规则(The properties of water and water vapor, according to the rules of the IAPWS-IF97)

说明：  一些有关卡尔曼滤波器的资料，非常全面，对关卡尔曼滤波器的原理用法都有详细的介绍(Some of the Kalman filter the information, very comprehensive, right off the principle of use of the Kalman filter are introduced in detail)

L系统单一规则生成Koch曲线源代码，可通过改变初始元、生成元、角度和压缩因子等生成要素绘制出许多“简单”分形图形。（非原创，原程序存在错误，我进行了修改，可能扔存在错误。）(L system single rule Koch curve generated source code can be changed by the initial yuan, generators, angle and compression factor generated elements drawn many "simple" fractals. (Non-original, there is an error in the original proceedings, I made amendments may throwing errors.))

通过红外控制，可以调整时钟的显示数字。lcd显示的年月日可以调整，还具有定时功能。定时可以使电机转动(the IR contorl the lcd)
