请问有人可以为I2C主模式建议vhdl代码吗？

我正在开发一个涉及I2C（使用Spartan 3E FPGA）与EEPROM通信的项目。
我对如何开始感到很困惑。
有人可以建议一个I2C主模式的vhdl代码吗？
在网上搜索“I2C核心”。
如果您还不熟悉I2C协议，那么了解I2C应该是您的第一步。
关于I2C的维基百科文章是一个良好的开端，其中包含指向I2C规范和相关文档的链接。

阅读手册或用户指南。
你读过手册了吗？
你能找到手册吗？2。
搜索开云(中国)官方（并搜索网页）以寻找类似的主题。
不要在多个开云(中国)官方上发布相同的问题。
不要在别人的主题上发布新主题或问题，开始新的主题！5。
学生：复制代码与学习设计不同.6“它不起作用”不是一个可以回答的问题。
提供有用的详细信息（请与网页，数据表链接）.7。
您的代码中的评论不需要支付额外费用。
我没有支付开云(中国)官方帖子的费用。
如果我写一篇好文章，那么我一无所获。

I'm working on a project involving I2C(using Spartan 3E FPGA) to communicate with EEPROM. I'm quite confused on how to start. Can someone suggest a vhdl code for an I2C Master mode?
 
Search the web for "I2C core".  If you are not yet familiar with I2C protocol, then learning about I2C should be your first effort.  The Wikipedia article on I2C is a good start, with links to the I2C specification and related docs.

Summary:
1. Read the manual or user guide.  Have you read the manual? Can you find the manual?
2. Search the forums (and search the web) for similar topics.
3. Do not post the same question on multiple forums.
4. Do not post a new topic or question on someone else's thread, start a new thread!
5. Students: Copying code is not the same as learning to design.
6 "It does not work" is not a question which can be answered. Provide useful details (with webpage, datasheet links, please).
7. You are not charged extra fees for comments in your code.
8. I am not paid for forum posts.  If I write a good post, then I have been good for nothing.

我见过的I2C内核比你需要的东西要复杂得多
与单个EEPROM交谈。
大多数支持多个主设备，时钟延长，10位寻址，
并且通常在同一个核心中有一个奴隶和一个主人。
如果可以的话，您可以从EEPROM数据表中找到足够的自己的I2C主设备
你有I2C总线的是FPGA和EEPROM。
我用HDL（Verilog）完成了这个
并使用PicoBlaze（汇编语言中的位冲击）。
如果您打算使用EDK（MicroBlaze）的嵌入式处理器，那么就有一个I2C
EDK附带的IP核。
在这些开云(中国)官方上搜索“I2C Master VHDL”也是值得的，因为我相信那里
在这个问题上有很多主题。

以下为原文

The I2C cores I've seen have all been way more complex than you need for something like
talking to a single EEPROM.  Most support multiple masters, clock stretching, 10 bit addressing,
and usually have a slave as well as a master in the same core.
 
You can find out enough to roll your own I2C master from the EEPROM data sheet if all
you have on that I2C bus is the FPGA and the EEPROM.  I've done this both with HDL (Verilog)
and using PicoBlaze (bit-banging in assembly language).
 
If you intend to have an embedded processor using EDK (MicroBlaze), there is an I2C
IP core that comes with the EDK.
 
It's also worth searching these forums for "I2C Master VHDL" because I believe there
are quite a few threads on this subject.
