管理系统上位机软件开发准备工作

Question

刚刚大学毕业，现在老总让我进行上位机软件开发，可是我开始连上位机是什么都不知道，现在只是零零碎碎的从网上了解了下可以用vb开发，我现在除了老总发给我的一些RS485代码，什么串口通信啊音频接口啊通通不了解，请问应该看哪方面的书或者哪方面的论坛呢。万分感谢。
刚刚踏入半只脚。

Answer 1

对于串口通信，建议你去了解一下 VB.NET 或者 C# 中使用 serial port Represents a serial port resource. https://docs.microsoft.com/en-us/dotnet/api/system.io.ports.serialport?view=dotnet-plat-ext-5.0 进行串口通信的知识。

另外对于在 RS485上进行串行通信，可以看看以下链接中的建议:

1. Serial Communication over RS485 Hello, I am new to this forum, but I have learned a lot from reading on here. I am developing a software which communicates with approximately 12 different devices over RS485. I specifically have learned a lot from a post on here a few years back that has now become the basis for my serial communication code. Of these 12 devices I am communicating with, there are 3 different manufacturers so each manufacturers equipment has its own protocol and timing as far as receiving and responding to https://www.vbforums.com/showthread.php?824641-Serial-Communication-over-RS485
2. C# with RS485/Serial Port Communication I have to work with a device that uses RS485 protocol to talk to a PC. So there are two things I need to get done: 1. Use an RS485 connector to connect the device to my PC. But I don't have an RS485 port on my machine. On checking the internet I found I could use a bridge to convert RS485 to RS232 and back. Supposing that's the way I have to go, will it impact the communication with the device in any way? Will I then have to code the app to use RS232? 2. Secondly, are there any https://www.vbforums.com/showthread.php?637402-C-with-RS485-Serial-Port-Communication

以上希望对你有帮助。
