`appleir` — Apple IR 接收器驱动

## 名称

`appleir` 接收器驱动

## 概要

要将此驱动编译进内核，请将以下行放入你的内核配置文件中：

> device appleir device hidbus device hid device evdev

或者，要在引导时以模块形式加载该驱动，请在 loader.conf(5) 中加入以下行：

```sh
appleir_load="YES"
```

## 描述

`appleir` 驱动为 Mac 计算机（2006-2011 年代）中发现的 Apple IR 接收器提供支持。它支持 Apple Remote 遥控器以及使用 NEC 红外协议的通用红外遥控器。

支持的设备包括：

* Apple IR Receiver（USB 产品 ID 0x8240、0x8241、0x8242、0x8243、0x1440）

该驱动解码专有的 Apple Remote 按键按下，并为通用红外遥控器使用的常见 NEC 协议代码提供默认键映射。未映射的按键代码可通过 `/dev/hidrawX` 处的原始 HID 设备访问，以便进行自定义用户空间重映射。

`/dev/input/eventX` 设备将遥控器呈现为具有标准 KEY\_\* 代码的 evdev 输入设备，适用于媒体应用程序。

## 硬件

`appleir` 驱动支持 USB 厂商 ID 为 0x05ac 且具有以下产品 ID 的 Apple IR 接收器：

**0x8240** Apple IR Receiver（第一代）

**0x8241** Apple IR Receiver

**0x8242** Apple IR Receiver（Mac Mini 2011、MacBook Pro 3,1）

**0x8243** Apple IR Receiver

**0x1440** Apple IR Receiver（超薄）

## 文件

**`/dev/input/eventX`** evdev 输入设备

**`/dev/hidrawX`** 用于自定义按键映射的原始 HID 设备

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/appleir.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
