串口示波器VisualScope
串口调试示波器＋高速数据采集
　　本程序在相应硬件（如USB转TTL，高速RS232等）支持下能够进行串口高速数据采集，并使数据在PC机上实时图形显示。
　　正常操作时，点击RUN按钮，打开串口接收功能，软件将从串口接收到的数据实时图形化显示。
　　下位机只要按照如下格式通过串口向上发送数据，上位机即可将接收到的数据显示成为波形。
the communication adapt 2 communication protocol,one is check sum,the other is CRC16.
if check sum is used,when RUN button is pressed,9 bytes is sent from COM?,
//-------------------------------------------------------------------------------------------
the data format is like this
Ch1_Addr_L，Ch1_Addr_H，
Ch2_Addr_L，Ch2_Addr_H，
Ch3_Addr_L，Ch3_Addr_H，
Ch4_Addr_L，Ch4_Addr_H，
//-------------------------------------------------------------------------------------------
The data from MPU to computer should be like this:
//-------------------------------------------------------------------------------------------
Ch1Data_L，Ch1Data_H，
Ch2Data_L，Ch2Data_H，
Ch3Data_L，Ch3Data_H，
Ch4Data_L，Ch4Data_H，
e.g 0x11 0x22 0x33 0x44 0x55 0x66 0x77 0x88 0x64, 64 is the sum
//-------------------------------------------------------------------------------------------
if CRC16 verification is used ,when RUN button is pressed,10 bytes is sent from COM?,
//-------------------------------------------------------------------------------------------
The data from computer to MPU is like this:
Ch1_Addr_L，Ch1_Addr_H，
Ch2_Addr_L，Ch2_Addr_H，
Ch3_Addr_L，Ch3_Addr_H，
Ch4_Addr_L，Ch4_Addr_H，
CRC16_L，CRC16_H
//-------------------------------------------------------------------------------------------
The data from MPU to computer should be like this:
//-------------------------------------------------------------------------------------------
Ch1_Data_L，Ch1_Data_H，
Ch2_Data_L，Ch2_Data_H，
Ch3_Data_L，Ch3_Data_H，
Ch4_Data_L，Ch4_Data_H，
CRC16_L，CRC16_H
当下位机持续向上位机发送满足要求的数据时，软件则会将收到的数据显示为4条曲线。

你可能喜欢接触智能车来，说道上位机，以前看到有人在论坛里分享了visualscope，这几天用了下，过程中也遇到了一些问题，首先先说怎么用吧，也帮助一些准备使用同学，给他们一些参考，我当时就自己摸索浪费了好长时间。
& && &首先先配置波特率，com口等基本配置。如图：
& && &在菜单栏Setup里面选择第一个选项，或者单击右下方状态栏，
& && &然后你会发现Setup第二个选项是选择协议，有两种，分别是check sum 和crc 。我这里选择check sum。
& && &然后下面要做的就是发送格式。看这里。
& &&&所以你要按着这个协议发送数据。
& &&&通道一地址低字位的低字节 ，通道一地址低字位的高字节 ，
& &&&通道一地址高字位的低字节 ，通道一地址高字位的高字节 ，
& &&&以此类推。。。
& &&&然后&&chkSum.
& &&&下面就是发送数据。
& &&&通道一数据低字节 ，通道一数据高字节 ，
& &&&.....
& &&&chksum。
& &&&有同学会问chksum是什么，其实就是你所有字节相加，最后于0xff与以下得到的字节，至于个通道的地址，在这里设置：
好了，按着这样协议就可以使用visualscope。
& &&&下面就是有些问题想请教使用过的打什么？为什么我发送个常数它的波形是三角波啊，像这样：
& &&&他每次画出我发送的数之后都会回到原点，能不能让它在我发送下个数之前不会到原点，就最简单的，我如何让它画出一个方波的波形啊，请各位使用过的大神们教一下小弟。。。

C++ names can be used only in certain regions of a program. This area is called the "scope" of the name. Scope determines the "lifetime" of a name that does not denote an object of static extent. Scope also determines the visibility of a name, when class constructors and destructors are called, and when variables local to the scope are initialized. (For more information, see
and .) There are five kinds of scope:
Local scope
A name declared within a block is accessible only within that block and blocks enclosed by it, and only after the point of declaration. The names of formal arguments to a function in the scope of the outermost block of the function have local scope, as if they had been declared inside the block enclosing the function body. Consider the following code fragment:
Because the declaration of i is in a block enclosed by curly braces, i has local scope and is never accessible because no code accesses it before the closing curly brace.
Function scope
Labels are the only names that have function scope. They can be used anywhere within a function, but are not accessible outside that function.
File scope
Any name declared outside all blocks or classes has file scope. It is accessible anywhere in the translation unit after its declaration. Names with file scope that do not declare static objects are often called global names.
In C++, file scope is also known as namespace scope.
Class scope
Names of class members have class scope. Class member functions can be accessed only by using the member-selection operators (. or –&) or pointer-to-member operators (.* or –&*) on an object or pointer to an
nonstatic class member data is considered local to the object of that class. Consider the following class declaration:
class Point
The class members x and y are considered to be in the scope of class Point.
Prototype scope
Names declared in a function prototype are visible only until the end of the prototype. The following prototype declares three names (strDestination, numberOfElements, and strSource); these names go out of scope at the end of the prototype:
errno_t strcpy_s( char *strDestination, size_t numberOfElements, const char *strSource );
