如何将外部ADC（ADS7883）连接到spartan-3E？

阅读ADS7883数据表。
了解ADS7883接口信号的时序要求。
设计FPGA的接口控制器逻辑。
编写源代码以实现您的设计。
构建（合成）它，模拟它，测试它，调试它。

阅读手册或用户指南。
你读过手册了吗？
你能找到手册吗？2。
搜索论坛（并搜索网页）以寻找类似的主题。
不要在多个论坛上发布相同的问题。
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。

如果我写一篇好文章，那么我一无所获。



以下为原文

• Read the ADS7883 datasheet.
  
• Understand the timing requirements of the ADS7883's interface signals.
  
• Design the interface controller logic for the FPGA.
  
• Write the source code to implement your design.
  
• Build (synthesise) it, simulate it, test it, debug it.

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.

发现您从200X年一直到2014年都在帮助网友解答问题，您真的太厉害了！

非常感谢eteam00
我做了你提到的所有列出的指令，它真的很有帮助。
我有另一个问题。
我有一个外部板FX2-BB，ADC（ADS7883）已连接到它。
但是，我不知道如何将FPGA spartan-3E中的时钟连接到外部ADC。
通过（D10）？
因为时钟的另一个引脚如D9和E10
谢谢



以下为原文

Thanks a lot eteam00
 
I did all the listed instructions that you mentioned it is really helpfull.
 
I have another question. I have an external board FX2-BB and the ADC (ADS7883)is already connected to it. However, I don't know how to connect the clock in  the FPGA spartan-3E to the external ADC. Is it through (D10)? Because there is another pins for the clock like D9 and E10
 
 
thank you

您告诉我们您使用的是哪个设备系列，但您尚未向我们展示：
哪个电路板（带原理图）
哪个FPGA封装
ADS7883子板的原理图。
你想怎么样？

以下为原文

You have told us which device family you are using, but you have yet to show us:

• which circuit board (with schematics)
  
• which FPGA package
  
• the schematic of the ADS7883 daughter board.
  

How would you like to proceed?
