编译工程
|
||
=========================
|
||
|
||
请使用以下命令，编译烧录工程：
|
||
|
||
.. code-block:: batch
|
||
|
||
idf.py build
|
||
|
||
运行以上命令可以编译应用程序和所有 ESP-IDF 组件，接着生成引导加载程序、分区表和应用程序二进制文件。
|
||
|
||
.. code-block:: none
|
||
|
||
$ idf.py build
|
||
Running cmake in directory /path/to/hello_world/build
|
||
Executing "cmake -G Ninja --warn-uninitialized /path/to/hello_world"...
|
||
Warn about uninitialized values.

[527/527] Generating hello_world.bin
|
||
esptool.py v2.3.1
|
||
|
||
Project build complete. To flash, run this command:
|
||
../../../components/esptool_py/esptool/esptool.py -p (PORT) -b 921600 write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x10000 build/hello_world.bin build 0x1000 build/bootloader/bootloader.bin 0x8000 build/partition_table/partition-table.bin
|
||
or run 'idf.py -p PORT flash'
|
||
|
||
如果一切正常，编译完成后将生成 .bin 文件。
|
||
|
||
|
||
烧录到设备
|
||
=============================
|
||
|
||
请运行以下命令，将刚刚生成的二进制文件烧录至您的 {IDF_TARGET_NAME} 开发板：
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py -p PORT flash
|
||
|
||
请将 PORT 替换为 {IDF_TARGET_NAME} 开发板的串口名称。如果 ``PORT`` 未经定义，:ref:`idf.py` 将尝试使用可用的串口自动连接。
|
||
|
||
更多有关 idf.py 参数的详情，请见 :ref:`idf.py`。
|
||
|
||
.. note::
|
||
|
||
勾选 ``flash`` 选项将自动编译并烧录工程，因此无需再运行 ``idf.py build``。
|
||
|
||
若在烧录过程中遇到问题，请前往 :doc:`flashing-troubleshooting` 或 :doc:`establish-serial-connection` 获取更多详细信息。
|
||
|
||

如果一切顺利，烧录完成后，开发板将会复位，应用程序 "hello_world" 开始运行。
|
||
|
||
如果您希望使用 Eclipse 或是 VS Code IDE，而非 ``idf.py``，请参考 `Eclipse Plugin <https://github.com/espressif/idf-eclipse-plugin/blob/master/README_CN.md>`_，以及 `VSCode Extension <https://github.com/espressif/vscode-esp-idf-extension/blob/master/docs/tutorial/install.md>`_。
|
||
|
||
监视输出
|
||
===============
|
||
|
||
您可以使用 ``idf.py -p PORT monitor`` 命令，监视 “hello_world” 工程的运行情况。注意，不要忘记将 PORT 替换为您的串口名称。
|
||

此时，您就可以在启动日志和诊断日志之后，看到打印的 “Hello world!” 了。

您可使用快捷键 ``Ctrl+]``，退出 IDF 监视器。
|
||
|
||
.. only:: esp32 or esp32c2
|
||
|
||
如果 IDF 监视器在烧录后很快发生错误，或打印信息全是乱码（如下），很有可能是因为您的开发板采用了 26 MHz 晶振，而 ESP-IDF 默认支持大多数开发板使用的 40 MHz 晶振。
|
||
|
||

|
||
:align: center
|
||
:alt: 乱码输出
|
||
:figclass: align-center
|
||
|
||
此时，您可以：
|
||
|
||
1. 退出监视器。
|
||
2. 返回 ``menuconfig``。
|
||
3. 进入 ``Component config`` --> ``Hardware Settings`` --> ``Main XTAL Config`` --> ``Main XTAL frequency`` 进行配置，将 :ref:`CONFIG_XTAL_FREQ_SEL` 设置为 26 MHz。
|
||
4. 重新 ``编译和烧录`` 应用程序。
|
||
|
||
在当前的 ESP-IDF 版本中，{IDF_TARGET_NAME} 支持的主晶振频率如下：
|
||
|
||
.. list::
|
||
|
||
:SOC_XTAL_SUPPORT_24M: - 24 MHz
|
||
:SOC_XTAL_SUPPORT_26M: - 26 MHz
|
||
:SOC_XTAL_SUPPORT_32M: - 32 MHz
|
||
:SOC_XTAL_SUPPORT_40M: - 40 MHz
|
||
|
||
.. note::
|
||
|
||
您也可以运行以下命令，一次性执行构建、烧录和监视过程：
|
||
|
||
``idf.py -p PORT flash monitor``
|
||
|
||
此外，
|
||
|
||
- 请前往 :doc:`IDF 监视器 <../api-guides/tools/idf-monitor>`，了解更多使用 IDF 监视器的快捷键和其他详情。
|
||
- 请前往 :ref:`idf.py`，查看更多 ``idf.py`` 命令和选项。
|
||
|
||
**恭喜，您已完成 {IDF_TARGET_NAME} 的入门学习！**
|
||
|
||
现在，您可以尝试一些其他 :idf:`examples`，或者直接开发自己的应用程序。
|
||
|
||
.. 重要::
|
||
|
||
一些示例程序不支持 {IDF_TARGET_NAME}，因为 {IDF_TARGET_NAME} 中不包含所需的硬件。
|
||
|
||
在编译示例程序前请查看 README 文件中 ``Supported Targets`` 表格。如果表格中包含 {IDF_TARGET_NAME}， 或者不存在这个表格，那么即表示 {IDF_TARGET_NAME} 支持这个示例程序。

其他提示
|
||
===============
|
||
|
||
权限问题 /dev/ttyUSB0
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
使用某些 Linux 版本向 {IDF_TARGET_NAME} 烧录固件时，可能会出现 ``Failed to open port /dev/ttyUSB0`` 错误消息。此时可以将用户添加至 :ref:`Linux Dialout 组<linux-dialout-group>`。
|
||
|
||
兼容的 Python 版本
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
ESP-IDF 支持 Python 3.7 及以上版本，建议升级操作系统到最新版本从而更新 Python。也可选择从 `sources <https://www.python.org/downloads/>`_ 安装最新版 Python，或使用 Python 管理系统如 `pyenv <https://github.com/pyenv/pyenv>`_ 对版本进行升级管理。
|
||
|
||
.. only:: esp32 or esp32s2 or esp32s3
|
||
|
||
..
|
||
当在上述行中添加新目标时，请同时更新 windows-start-project.rst 和 linux-macos-start-project.rst 中的列表。
|
||
|
||
|
||
上手板级支持包
|
||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
||
您可以使用 `板级支持包 (BSP) <https://github.com/espressif/esp-bsp>`_，协助您在开发板上的原型开发。仅需要调用几个函数，便可以完成对特定开发板的初始化。
|
||
|
||
一般来说，BSP 支持开发板上所有硬件组件。除了管脚定义和初始化功能外，BSP 还附带如传感器、显示器、音频编解码器等外部元件的驱动程序。
|
||
|
||
BSP 通过 :doc:`IDF 组件管理器 </api-guides/tools/idf-component-manager>` 发布，您可以前往 `IDF 组件注册器 <https://components.espressif.com>`_ 进行下载。
|
||
|
||
.. only:: esp32
|
||
|
||
**以下示例演示了如何将 ESP-WROVER-KIT BSP 添加到项目中：**
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py add-dependency esp_wrover_kit
|
||
|
||
.. only:: esp32s2
|
||
|
||
**以下示例演示了如何将 ESP32-S2-Kaluga-Kit BSP 添加到项目中：**
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py add-dependency esp32_s2_kaluga_kit
|
||
|
||
.. only:: esp32s3
|
||
|
||
**以下示例演示了如何将 ESP-BOX BSP 添加到项目中：**
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py add-dependency esp-box
|
||
|
||
更多有关使用 BSP 的示例，请前往 `BSP 示例文件夹 <https://github.com/espressif/esp-bsp/tree/master/examples>`_。
|
||
|
||
擦除 flash
|
||
~~~~~~~~~~~
|
||
|
||
ESP-IDF 支持擦除 flash。请运行以下命令，擦除整个 flash：
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py -p PORT erase-flash
|
||
|
||
若存在需要擦除的 OTA 数据，请运行以下命令：
|
||
|
||
.. code-block:: bash
|
||
|
||
idf.py -p PORT erase-otadata
|
||
|
||
擦除 flash 需要一段时间，在擦除过程中，请勿断开设备连接。
