visual-studio-code - PlatformIO不会在VS Code中创建firmware.bin

Question

我下载了一些固件的更新版本，需要将其编译成 firmware.bin 文件(firmware.hex 不起作用)。大多数在线教程都说要使用 PlatformIO 来实现此目的，但每当我构建固件时，一切都会按计划进行，编译时没有任何错误，并表示它成功了。但是，在大多数 YouTube 视频或在线文档中，最后几行包含类似

Archiving .pio\build\mega2560\libFrameworkArduino.a
Archiving .pio\build\mega2560\lib9e6\libU8glib-HAL_ID1932.a
Linking .pio\build\mega2560\firmware.elf
Building .pio\build\mega2560\firmware.hex
Checking size .pio\build\mega2560\firmware.elf
Building .pio\build\mega2560\firmware.bin
RAM:   [======    ]  60.6% (used 4963 bytes from 8192 bytes)
Flash: [======    ]  63.7% (used 161682 bytes from 253952 bytes)
================================================ [SUCCESS] Took 222.23 seconds ================================================

虽然我的看起来像这样:

Archiving .pio\build\mega2560\libFrameworkArduino.a
Archiving .pio\build\mega2560\lib9e6\libU8glib-HAL_ID1932.a

================================================ [SUCCESS] Took 222.23 seconds ================================================

果然，有 firmware.elf 和 firmware.hex，但没有 firmware.bin。 Many other places说 platformio 默认创建一个 .bin 文件，所以我不认为这是我忘记做的事情，但那是什么？我需要编辑 Platformio.ini 文件或其他文件吗？

我在构建 arduino 时遇到了同样的问题。我找到的解决方案是在工作区添加一个 extra_script.py 文件来编译 bin。

引用文献

• 后期编译详细信息: https://docs.platformio.org/en/latest/projectconf/advanced_scripting.html#before-pre-and-after-post-actions

• 脚本详细信息 https://community.platformio.org/t/add-t-none-or-t-binary/441/14

基本上，您希望将 extra_scripts 行添加到 platformio.ini 文件中

; you env might be different to might platform, board and framework be
[env:nanoatmega328]
platform = atmelavr
board = nanoatmega328
framework = arduino

extra_scripts = post:extra_script.py

extra_script.py 文件与 platformio.ini 位于同一文件夹中

from os.path import join
Import("env", "projenv")

# Custom BIN from ELF
env.AddPostAction(
    "$BUILD_DIR/${PROGNAME}.elf",
    env.VerboseAction(" ".join([
                "$OBJCOPY",
                "-O",
                "binary",
                "$TARGET",
                "$BUILD_DIR/${PROGNAME}.bin"
            ]), "Building $TARGET"))
