代码说明:

 上位机相当于一个软件系统,可以用于接收数据、控制数据。即可以对接收到的数据直接发送操控命令来操作数据。上位机可以接收下位机的信号。下位机是一个控制器,是直接控制设备获取设备状况的计算机。上位机发出的命令首先给下位机,下位机再根据此命令解释成相应时序信号直接控制相应设备。下位机不时读取设备状态数据(一般为模拟量),转换成数字信号反馈给上位机。上位机不可以单独使用,而下位机可以单独使用

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    蜂鸣器奏乐刘德华《练习》,根据不同的单片机可以调整延时。8952单片机不能执行程序,但将数组的xdata改为code可以演奏一小段。需要高级一点的单片机。在不同的开发板上运行的效果有差异。(Buzzer music to Andy, " practicing" , depending on the chip can be adjusted delay. 8952 microcontroller can execute the program, but will be replaced by code xdata array can play short. Require senior point microcontrollers. The development board running at different effects are different.)

  • revit二次开发获取纹理贴图
    过IExportContext导出类中的Onmaterial()方法,可以获取到材质相关信息,主要是材质ID,再根据材质ID得到材质对象material,然后通过如下代码获取Asset对象: ElementId appearanceId = material.AppearanceAssetId; AppearanceAssetElement appearanceElem = document.GetElement(appearanceId) as AppearanceAssetElement; Asset theAsset = appearanceElem.GetRenderingAsset(); 这个Asset对象里面就包含了所有外观渲染相关的数据,包括材质的贴图。判断属性名为“unifiedbitmap_Bitmap”的属性,即为想要的纹理图,具体Asset属性的读取可以在Revit的API文档中搜Asset,会有例子介绍。

    . Introduction. This software library implements the maxflow algorithm described in "An Experimental Comparison of Min-Cut/Max-Flow Algorithms for Energy Minimization in Vision." Yuri Boykov and Vladimir Kolmogorov. In IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI),  September 2004 This algorithm was developed by Yuri Boykov and Vladimir Kolmogorov at Siemens Corporate Research. To make it available for public use, it was later reimplemented by Vladimir Kolmogorov based on open publications. If you use this software for research purposes, you should cite the aforementioned paper in any resulting publication.
