Thanks for taking a moment to read my question. 感谢您抽出时间阅读我的问题。 I am a starving intern and I really want to get some work done! 我是一个挨饿的实习生，我真的很想完成一些工作！

I have a sensor device, OEM, that I will be adding to a dragonboard like this. 我有一个传感器设备OEM，我将像这样将其添加到Dragonboard中。 http://mydragonboard.org/ http://mydragonboard.org/

Unfortunately I have wasted a lot of time researching how to write a driver to interact with my sensor over I2C and I have ended up confused, mostly because none of my resources are consistent with where to put what code. 不幸的是，我浪费了很多时间研究如何编写驱动程序以通过I2C与我的传感器进行交互，最终我感到困惑，主要是因为我的资源都与放置什么代码不一致。 I read a lot of "Embedded Android", "Linux Device Drivers", and "Sensor PortingGuide" (Oreilly, Oreilly, TI) and have not gotten a solid answer on how to GET IT DONE. 我读了很多“嵌入式Android”，“ Linux设备驱动程序”和“ Sensor PortingGuide”（Oreilly，Oreilly，TI），但对于如何完成它并没有一个明确的答案。

My goal is to eventually have this implemented with a HAL and available to the SensorService and Sensor Manager. 我的目标是最终通过HAL来实现此功能，并可供SensorService和Sensor Manager使用。

Thanks ! 谢谢！

i2c driver does not change much depending on Android or Linux. i2c驱动程序的变化不大，具体取决于Android或Linux。 You can go through a simple already implemented i2c driver in http://lxr.linux.no/ 您可以在http://lxr.linux.no/中浏览一个简单的已经实现的i2c驱动程序

one example : understand implemented driver at lxr: /kernel/drivers/input/misc/* 一个示例：在lxr上了解实现的驱动程序：/ kernel / drivers / input / misc / *
