如何将 iOS 设备连接到自定义 USB 设备？
我正在开发一种定制电子设备 - 将其视为一种特殊的数据记录器，我需要将计算机连接到它来配置它并提取数据。
我知道我可以在 PC 上轻松完成此操作，但我想使用 iOS 设备来执行此操作。
有两个问题：
我可以使用常规底座连接器/USB 电缆来完成此操作吗？ EA 框架会让我完成所有通信吗？
提取数据后，从 iPad 中提取数据的最佳方法是什么？用它写一封电子邮件，保存到保管箱之类的？
谢谢！
I'm developing a custom electronic device - think of it as a special kind of data logger, and I need to connect a computer to it to configure it and to extract the data.
I know I can do this without too much trouble on a PC, but I'd like to use an iOS device to do this.
Two questions:
Can I do this with a regular dock connector / USB cable? Will the EA framework let me do all the communicating?
Once I have extracted the data, what's the best way to get that out of the iPad? Make an email with it, save to a dropbox or something?
Thanks!

Afaik，您需要加入 MFi 计划才能为 iPad/iPhone 制作 USB 配件。这将为您提供所需的所有技术资源。
至于数据传输只有“意见”，我说发送的选项越多越好。只是不要强迫用户多次选择，然后在设置中更改它。
Afaik, you need to join the MFi program to make USB accessories for iPad/iPhone. That will give you all the technical resources needed.
As for data transfer there are only "opinions", I say the more options of sending, the better. Just don't force the user to choose more than once, then make it changeable in settings.
如果您进行的通信非常简单，您可能可以摆脱 使用耳机插孔。
这很好，因为你的设备只要编写相应的软件就可以跨平台（iOS、Android、Mac/PC），而且不需要经过苹果的 MFi 审批程序。像 Square 信用卡扫描仪一样思考。
If you're doing very light communication, you might be able to get away with using the headphone jack.
This is nice because your device can be cross-platform (iOS, Android, Mac/PC) as long as you write the corresponding software, and because you don't need to go through Apple's MFi approval program. Think like the Square credit card scanner.
您必须编写设备和 iOS 设备之间的通信堆栈，但是您可以。
关于使用 EA.framework 的文档很少。所有有趣的部分都在 Mfi 计划中，但苹果对访问它的要求非常严格。
因此，如果您成功，共享教程将使您成为 EA 英雄；）
关于共享您的数据，恕我直言，电子邮件 + CSV 是一个成功的组合。
You will have to write the communication stack between the device and your iOS device but yes, you can.
there's very few docs about using the EA.framework. All the juicy parts are in the Mfi program but Apple is very strict about giving access to it.
So if you succeed, sharing a tuto will make you a EA hero ;)
About sharing your data, imho, email + CSV is a winning combo.
如果您想将某些东西插入坞站连接器，您需要查看 https://developer。 apple.com/programs/mfi/
If you want to plug something into the dock connector, you want to have a look at https://developer.apple.com/programs/mfi/
