如何在C＃中获得体重秤指标 [英] How to get weight scale indicator in C#

问题描述

HELLO，

我正在尝试开发一个小软件来保存sql数据库中的重量记录。我正在使用c＃环境。我是c＃的新手，但尽可能多地编码。我编码从指标读取。但是有一些问题，

1.我无法获得数字？标记而不是实际阅读。

2.我的阅读指标为25.07。但我只有1？标记作为回报。

在超级终端我获得实际读数但在我的应用程序中我遇到了问题。

推荐答案

首先使用HyperTerminal或类似方法检查通信设置 - 当您可以使用它正确读取数据时，传输这些设置（波特率，每个字符位，奇偶校验，停止位）到您的代码中，看看您是否可以复制超级终端显示的内容。在你能做到这一点之前，你无法确定到底发生了什么！

Start by checking your communications settings using HyperTerminal or similar - when you can read the data properly using that, transfer those settings (Baud rate, bits per char, parity, stop bits) into your code and see if you can duplicate what hyperterminal shows. Until you can do that, you can't be sure what the heck is happening!

？表示您需要检索/解析状态字节以获取有关比例当前状态的其他信息（例如运动中;等）。

"?" means that you need to retrieve / parse the "status byte" to get additional information about the current status of the scale (e.g. "in motion"; etc).

此讨论应该关闭。我解决了我离开c＃项目的问题。在vb.net中，我得到了我想要的阅读。感谢所有和我在一起的朋友...

this discussion should be closed. i solved my issue leaving c# project. in vb.net i got the reading as i want. thanx to all friends being with me...
