如何将命令从C＃发送到硬件板。 [英] How to send Command from C# to hardware board.

问题描述

我正在使用c＃设计用户界面。我通过usb通信将我的硬件套件连接到PC，我从用户界面（PC）发送一些命令以从硬件获取数据。

我成功发送命令并从硬件接收响应。 />


我发送的命令如下

Hi,

I am designing user interface using c#. I have connected my hardware kit to PC via usb communication and i am sending some commands from user interface(PC) to get data from hardware.
I am successfully sending commands and receiving response from hardware.

I am sending the command like this

SendCommand("TEMP");

我试图从用户界面发送Esc按钮命令。我的意思是我想像这样发送

I am trying to send "Esc" button command from user interface. I mean i want to send like this

SendCommand("27");

但不起作用。我认为ESC（字符27）按钮。



有谁能建议我如何发送？

but not working. I think ESC (character 27) button.

Can anyone suggest me how to send that?

推荐答案

假设SendCommand是您自己的方法，它只接受一个字符串：

Assuming that SendCommand is your own method, and it only accepts a string:

SendCommand("\x1b");

应该发送一个转义字符。

Should send a single escape character.

我不熟悉这个东西的类型。但我觉得这很有趣。你可以参考这些链接。如果您修改某些内容会很有帮助。



通过串口发送ENTER键 [ ^ ]



按下退出键按下应用程序 [ ^ ]



按Escape键调用方法 [ ^ ]



虚拟密钥代码 [ ^ ]



问候..：）

I am not familiar with this type of stuff. But i found this interesting.You can refer to these links. It would be helpful if you modify something.

Sending "ENTER" key through serial port[^]

Close Application at Press of Escape Button[^]

Press Escape key to call method[^]

Virtual-Key Codes[^]
