VC_MFC-Sample1
Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置
串口属性的实例.
在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口
进行通信.串口通信方便易行,应用广泛.
一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是
半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点.
每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正
确的命令后作出应答.
(Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

(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.)

DMX 512协议是Digital Multiplex的缩写,是灯光行业数字化设备的通用信号控制协议,同时也是是一种国际协议。 USITT DMX512/1990是调光和灯光控制台数据传输标准,是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多,现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年,在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)
