+# Espressif 物联网开发框架
+
+* [English Version](./README.md)
+
+[![Documentation Status](https://readthedocs.com/projects/espressif-esp-idf/badge/?version=latest)](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/?badge=latest)
+
+ESP-IDF 是由乐鑫官方推出的针对 [ESP32](https://espressif.com/en/products/hardware/esp32/overview) 系列芯片的开发框架。
+
+# 使用 ESP-IDF 进行开发
+
+## 搭建 ESP-IDF 开发环境
+
+请参阅如下指南搭建 ESP-IDF 的开发环境：
+
+* [ESP-IDF 稳定版本的入门指南](https://docs.espressif.com/projects/esp-idf/en/stable/get-started/)
+* [ESP-IDF 开发版本（master 分支）的入门指南](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/)
+
+### 非 GitHub 分叉的 ESP-IDF 项目
+
+ESP-IDF 中的子模块采用相对路径（[详见 .gitmodules 文件](.gitmodules)），所以它们会指向 GitHub。
+如果 ESP-IDF 被分叉到的仓库不在 GitHub 上，那么你需要在克隆结束后运行该[脚本](tools/set-submodules-to-github.sh)。它会为所有的子模块设置绝对路径，接着可以通过 `git submodule update --init --recursive` 完成子模块的更新。
+如果 ESP-IDF 是从 GitHub 上克隆得到，则不需要此步骤。
+
+## 寻找项目
+
+除了入门指南中提到的 [esp-idf 模板项目](https://github.com/espressif/esp-idf-template)，ESP-IDF 的 [examples](examples) 目录下还带有很多其它示例项目。
+
+一旦找到了需要的项目，便可以进入该目录，执行配置和构建操作。
+
+如果要基于示例工程开始你自己的项目，请将示例工程复制到 ESP-IDF 目录之外。
+
+# 快速参考
+
+详细的使用方法请参考上面入门指南的链接，这里仅仅列举一些 ESP-IDF 项目开发中常用的命令：
+
+## 设置构建环境
+
+（请参考入门指南中列出的详细步骤。）
+* 在主机中安装入门指南中提到的构建所依赖的工具。
+* 将 ESP-IDF 中的 `tools/` 目录加入 PATH 环境变量中。
+* 运行 `python -m pip install -r requirements.txt` 安装 Python 依赖库。
+
+## 配置项目
+
+`idf.py menuconfig`
+
+* 打开项目的文本配置菜单。
+* 使用上下键浏览菜单。
+* 使用回车键进入子菜单，退出键返回上一级菜单或者退出配置。
+* 输入 `?` 查看帮助界面，按下回车键可以退出帮助界面。
+* 使用空格键或者 `Y` 和 `N` 按键来启用和禁用带复选框“`[*]`”的配置项。
+* 高亮某个配置项的同时按下 `?` 键可以显示该选项的帮助文档。
+* 输入 `/` 可以搜索指定的配置项。
+
+一旦配置完成，请按下退出键多次以退出配置界面，当提示是否保存新的的配置时，选择 “Yes”。
+
+## 编译项目
+
+`idf.py build`
+
+编译应用程序，引导程序，并根据配置生成分区表。
+
+## 烧写项目
+
+当构建结束，终端会打印出一条命令行，告知如何使用 esptool.py 工具烧写项目到芯片中。但是你还可以运行下面这条命令来自动烧写：
+
+`idf.py -p PORT flash`
+
+将其中的 PORT 替换为系统中实际串口的名字（比如 Windows 下的 `COM3`，Linux 下的 `/dev/ttyUSB0`，或者 MacOS 下的 `/dev/cu.usbserial-X`。如果省略 `-p` 选项，`idf.py flash` 会尝试使用第一个可用的串口进行烧写。
+
+这会烧写整个项目（包括应用程序，引导程序和分区表）到芯片中，此外还可以使用 `idf.py menuconfig` 来调整串口烧写相关的配置。
+
+你也不必先运行 `idf.py build`，再运行 `idf.py flash`，`idf.py flash` 会根据需要自动重新构建项目。
+
+## 观察串口输入
+
+`idf.py monitor` 会调用 [idf_monitor 工具](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html)来显示 ESP32 的串口输出。`idf_monitor` 还包含一系列的功能来解析程序崩溃后的输出结果并与设备进行交互。更多详细内容，请参阅[文档](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
+
+输入 `Ctrl-]` 可退出监视器。
+
+想要一次性执行构建，烧写和监视，可以运行如下命令：
+
+`idf.py flash monitor`
+
+## 仅编译并烧写应用程序
+
+在第一次烧写过后，你可能只想构建并烧写你的应用程序，不包括引导程序和分区表：
+
+* `idf.py app` - 仅构建应用程序。
+* `idf.py app-flash` - 仅烧写应用程序。
+
+`idf.py app-flash` 会自动判断是否有源文件发生了改变而后重新构建应用程序。
+
+（在正常的开发中，即使引导程序和分区表没有发生变化，每次都重新烧写它们并不会带来什么危害。）
+
+## 擦除 Flash
+
+`idf.py flash` 并不会擦除 Flash 上所有的内容，但是有时候我们需要设备恢复到完全擦除的状态，尤其是分区表发生了变化或者 OTA 应用升级。要擦除整块 Flash 请运行 `idf.py erase_flash`。
+
+这条命令还可以和其余命令整合在一起，`idf.py -p PORT erase_flash flash` 会擦除一切然后重新烧写新的应用程序，引导程序和分区表。
+
+# 其它参考资源
+
+* 最新版的文档：https://docs.espressif.com/projects/esp-idf/ ，该文档是由本仓库 [docs 目录](docs) 构建得到。
+
+* 可以前往 [esp32.com 论坛](https://esp32.com/) 提问，挖掘社区资源。
+
+* 如果你在使用中发现了错误或者需要新的功能，请先[查看 GitHub Issues](https://github.com/espressif/esp-idf/issues)，确保该问题不会被重复提交。

+Using SendAcquire and SendComplete
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Items in no-split buffers are acquired (by SendAcquire) in strict FIFO order and must be sent to
+the buffer by SendComplete for the data to be accessible by the consumer. Multiple items can be
+sent or acquired without calling SendComplete, and the items do not necessarily need to be
+completed in the order they were acquired. However the receiving of data items must occur in FIFO
+order, therefore not calling SendComplete the earliest acquired item will prevent the subsequent
+items from being received.
+
+The following diagrams illustrate what will happen when SendAcquire/SendComplete don't happen in
+the same order. At the beginning, there is already an data item of 16 bytes sent to the ring
+buffer. Then SendAcquire is called to acquire space of 20, 8, 24 bytes on the ring buffer.

+.. packetdiag:: ../../../_static/diagrams/ring-buffer/ring_buffer_send_acquire_complete.diag
+    :caption: SendAcquire/SendComplete items in no-split ring buffers

+
+After that, we fill (use) the buffers, and send them to the ring buffer by SendComplete in the
+order of 8, 24, 20. When 8 bytes and 24 bytes data are sent, the consumer still can only get the
+16 bytes data item. Due to the usage if 20 bytes item is not complete, it's not available, nor
+the following data items.
+
+When the 20 bytes item is finally completed, all the 3 data items can be received now, in the
+order of 20, 8, 24 bytes, right after the 16 bytes item existing in the buffer at the beginning.
+
+Allow-split/byte buffers do not allow using SendAcquire/SendComplete since acquired buffers are

+C++ Code Formatting
+-------------------
+
+The same rules as for C apply. Where they are not enough, apply the following rules.
+
+File Naming
+^^^^^^^^^^^^
+C++ Header files have the extension ``.h``. C++ source files have the extension ``.cpp``, which is important for the compiler to distiguish them from normal C source files.
+
+Naming
+^^^^^^
+
+* **Class and struct** names shall be written in ``CamelCase`` with a capital letter as beginning. Member variables and methods shall be in ``snake_case``.
+* **Namespaces** shall be in lower ``snake_case``.
+* **Templates** are specified in the line above the function declaration.
+
+Member Order in Classes
+^^^^^^^^^^^^^^^^^^^^^^^
+
+First put the public members, then the protected, then private ones. Omit public, protected or private sections without any members.
+
+Spacing
+^^^^^^^
+
+* Don't indent inside namespaces.
+* Put ``public``, ``protected`` and ``private`` labels at the same indentation level as the corresponding ``class`` label.
+
+Simple Example
+^^^^^^^^^^^^^^^
+::
+
+    // file spaceship.h
+    #ifndef SPACESHIP_H_

 更新 ESP-IDF
-=================
+================
 
 乐鑫会不时推出更新版本的 ESP-IDF，修复 bug 或提出新的特性。因此，您在使用时，也应注意更新您本地的版本。最简单的方法是：直接删除您本地的 ``esp-idf`` 文件夹，然后按照 :ref:`get-started-get-esp-idf` 中的指示，重新完成克隆。 
 
-如果您希望将 ESP-IDF 克隆到新的路径下，请务必 :doc:`重新设置 IDF_PATH <add-idf_path-to-profile>`。否则，工具链将无法找到 ESP-IDF。
-
 此外，您可以仅更新变更部分。具体方式，请前往 :ref:`更新 <updating>` 章节查看。
 
+注意，更新完成后，请执行 ``install.sh`` （Windows 系统中为 ``install.bat``）脚本，避免新版 ESP-IDF 所需的工具也有所更新。具体请参考 :ref:`get-started-set-up-tools`。
+
+一旦重新安装好工具，请使用“导出脚本”更新环境，具体请参考 :ref:`get-started-set-up-env`。

-=========================
-
-.. include:: /_build/inc/download-links.inc
-
-Linux 版的 ESP32 工具链可以从 Espressif 的网站下载：
-
-- 64 位 Linux：
-
-  |download_link_linux64|
-
-- 32 位 Linux：
-
-  |download_link_linux32|
-
-1.  下载完成后，将它解压到 ``~/esp`` 目录：
-
-    - for 64-bit Linux:
-
-      .. include:: /_build/inc/unpack-code-linux64.inc
-
-    - for 32-bit Linux:
-
-      .. include:: /_build/inc/unpack-code-linux32.inc
-
-.. _setup-linux-toolchain-add-it-to-path:
-
-2.  工具链将会被解压到 ``~/esp/xtensa-esp32-elf/`` 目录。
-
-    要使用工具链，你还需要在 ``~/.profile`` 文件中更新环境变量 ``PATH``。要使 ``xtensa-esp32-elf`` 在所有的终端会话中都有效，需要将下面这一行代码添加到你的 ``~/.profile`` 文件中：::
-
-      export PATH="$HOME/esp/xtensa-esp32-elf/bin:$PATH"
-
-    或者，你也可以给上面的命令创建一个别名。这样做的好处是，你仅在需要时才获取工具链，将下面这行代码添加到 ``~/.profile`` 文件中即可::
-
-      alias get_esp32='export PATH="$HOME/esp/xtensa-esp32-elf/bin:$PATH"'
-
-    然后，当你需要使用工具链时，在命令行输入 ``get_esp32``，然后工具链会自动添加到你的 ``PATH`` 中。
-
-    .. note::
-
-        如果将 ``/bin/bash`` 设置为登录 shell，且同时存在  ``.bash_profile`` 和 ``.profile``，则更新 ``.bash_profile``。
-
-3.  退出并重新登录以使 ``.profile`` 更改生效。运行以下命令来检查 ``PATH`` 设置是否正确::
-
-        printenv PATH
-
-    检查字符串的开头是否包含类似的工具链路径::
-
-        $ printenv PATH
-        /home/user-name/esp/xtensa-esp32-elf/bin:/home/user-name/bin:/home/user-name/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

-

-
-完成下载后，请在 ``~/esp`` 目录下进行解压：
-
-.. include:: /_build/inc/unpack-code-osx.inc
-
-.. _setup-macos-toolchain-add-it-to-path:
-
-此后，该工具链将解压至 ``~/esp/xtensa-esp32-elf/`` 目录。
-
-为了开始使用工具链，你必须更新 ``~/.profile`` 文件中的 ``PATH`` 环境变量。为了让所有终端都可以使用 ``xtensa-esp32-elf``，请将下方命令增加至你的 ``~/.profile`` 文件：::
-
-    export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH
-
-此外，你可以为以上命令增加一个别名。这样，你就可以仅在有需要时获取工具链。具体方式是在 ``~/.profile`` 文件中增加下方命令::
-
-    alias get_esp32="export PATH=$HOME/esp/xtensa-esp32-elf/bin:$PATH"
-
-此时，你可以直接输入 ``get_esp32`` 命令，即可将工具链添加至你的 ``PATH``。
-
-注意，这里需要退出并重新登陆，``.profile`` 更改才会生效。
-
-此外，你可以使用以下命令，验证 ``PATH`` 是否设置正确::
-
-        printenv PATH
+    ``xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at:/Library/Developer/CommandLineTools/usr/bin/xcrun``

+=================
 
 .. note::
-   基于 GNU Make 的构建系统要求 Windows 兼容 `MSYS2`_ Unix。基于 CMake 的构建系统则无此要求。
+
+    较早版本 ESP-IDF 使用了 **MSYS2 bash 终端** 命令行。目前，基于 CMake 的编译系统可使用常见的 **Windows 命令窗口**，即本指南中使用的终端。
+
+    请注意，如果您使用基于 bash 的终端或 PowerShell 终端，一些命令语法将与下面描述有所不同。
+
+打开命令提示符，运行以下命令：
+
+.. include:: /_build/inc/git-clone-windows.inc
+
+ESP-IDF 将下载至 ``%userprofile%\esp\esp-idf``。
+
+请前往 :doc:`/versions`，查看 ESP-IDF 不同版本的具体适用场景。
+
+.. include:: /_build/inc/git-clone-notes.inc
+
+.. note::
+
+    在克隆远程仓库时，不要忘记加上 ``--recursive`` 选项。否则，请接着运行以下命令，获取所有子模块 ::
+    
+        cd esp-idf
+        git submodule update --init

+要安装 ESP-IDF 必备工具，最简易的方式是下载 ESP-IDF 工具安装器，地址如下：
 
-https://dl.espressif.com/dl/esp-idf-tools-setup-1.2.exe
+https://dl.espressif.com/dl/esp-idf-tools-setup-2.0.exe
 
-安装器会自动安装 ESP32 Xtensa gcc 工具链，Ninja_ 编译工具，以及名为 mconf-idf_ 的配置工具。此外，如果你的电脑还未安装有关 CMake_ 和 Python_ 2.7 的安装器，它还可以下载和运行与之对应的安装器。
+本安装器可为您安装所需的交叉编译器、OpenOCD、cmake_ 和 Ninja_ 编译工具，以及一款 mconf-idf_ 配置工具。此外，本安装器还可在有需要时下载、运行 Python_ 3.7 和 `Git For Windows` 的安装器。
 
-安装器默认更新 Windows ``Path`` 环境变量，因而上述工具也可在其他环境中运行。如果禁止该选项，则需自行设置 ESP-IDF 所使用的环境（终端或所选 IDE），并配置正确的路径。 
+本安装器还可用于下载任意 ESP-IDF 发布版本。
 
-请注意，此安装器仅针对 ESP-IDF 工具包，并不包括 ESP-IDF。
+使用命令提示符
+========================
 
-安装 Git
-==============
+在后续步骤中，我们将使用 Windows 的命令提示符进行操作。
 
-ESP-IDF 工具安装器并不会安装 Git，因为快速入门指南默认你将以命令行的模式使用它。你可以通过 `Git For Windows`_ 下载和安装 Windows 平台的命令行 Git 工具（包括 "Git Bash" 终端）。
+ESP-IDF 工具安装器可在“开始”菜单中，创建一个打开 ESP-IDF 命令提示符窗口的快捷方式。本快捷方式可以打开 Windows 命令提示符（即 cmd.exe），并运行 ``export.bat`` 脚本以设置各环境变量（比如 ``PATH``，``IDF_PATH`` 等）。此外，您可还以通过 Windows 命令提示符使用各种已经安装的工具。
 
-如果你想使用其他图形化 Git 客户端，如 `Github Desktop`， 你可以自行安装，但需要对本《入门指南》中相应的 Git 命令进行转换，以便用于你所选的 Git 客户端。
+注意，本快捷方式仅适用 ESP-IDF 工具安装器中指定的 ESP-IDF 路径。如果您的电脑上存在多个 ESP-IDF（比如您需要不同的 ESP-IDF 版本）需要使用快捷方式，您可以：
 
-使用终端
-================
+1. 为 ESP-IDF 工具安装器创建的快捷方式创建一个副本，并将新快捷方式的“当前路径”指定为您希望使用的 ESP-IDF 路径。
 
-在本《入门指南》接下来的步骤说明中，我们将使用终端命令提示符进行有关操作。你也可以使用任何其他形式的命令提示符：
-
-- 比如，Windows 开始菜单下内置的命令提示符。本文档中的所有 Windows 命令行指令均为 Windows 命令提示符中所使用的 "batch" 命令。
-- 你还可以使用 `Git for Windows`_ 中的 "Git Bash" 终端，其所使用的 "bash" 命令提示符语法与 Mac OS 或 Linux 的既定语法相同。安装此终端后，你可以在开始菜单下找到命令提示符窗口。
-- 如果你已安装 MSYS2_ （通过 ESP-IDF 之前版本），你还可以使用 MSYS 终端。
+2. 运行 ``cmd.exe``，并更新至您希望使用的 ESP-IDF 目录，然后运行 ``export.bat``。注意，这种方法要求 ``PATH`` 中存在 Python 和 Git。如果您在使用时遇到有关“找不到 Python 或 Git” 的错误信息，请使用第一种方法。
 
 后续步骤
 ==========
 
-要继续设置开发环境，请参照 :ref:`get-started-get-esp-idf`。
+当 ESP-IDF 工具安装器安装完成后，则开发环境设置也到此结束。后续开发步骤，请前往 :ref:`get-started-start-project` 查看。
