-The function clamps percentages above 100 and returns the LCD IO error on failure.
-It has no cached state; the optional framework adapter below retains the original
-cached getter, mutex, and interface lifecycle. RGB LCD boards do not use this
-QSPI AMOLED command.
-
-## Brookesia AMOLED brightness
-
-`integrations/brookesia_hal_custom/` provides one shared adapter for the 1.75C,
-1.8 V1, and 2.16 AMOLED profiles. It replaces their three identical brightness
-implementations. Board discovery and hardware initialization use `boards/` and
-do not select this component. Applications opt in when they need Brookesia HAL
-brightness control.
-
-The shared adapter preserves:
-
-- Device name `CustomDisplay`, interface implementation `CustomDisplay:Backlight`,
-  and display group `display_lcd`.
-- `set_brightness()` and `get_brightness()`, clamping to 0–100 percent and converting
-  to the panel's 0–255 brightness command (`0x51` over QSPI) through the public helper.
-- The mutex, unchanged-command suppression, error propagation, and initialization
-  behavior. The plugin starts at 0 percent; the application then chooses brightness.
-  `get_brightness()` returns the last successfully set value, not a hardware readback.
-- The original unsupported result for separate light on/off methods.
-
-The ordinary panel setup retains its existing initial-brightness command. The
-plugin is a framework interface adapter, not a replacement panel or PMU driver.
-
-## Explicit application setup
-
-Use **ESP-IDF 6.1** for the optional adapter. Brookesia HAL interface **0.8.2**
-and its lib_utils **0.8.2** dependency are tested. Upstream lib_utils 0.8 requires
-IDF **6.0 through 6.2**; it cannot resolve on IDF 5.5. This upstream framework
-requirement does not apply to the ordinary board pack, which continues to build
-on IDF 5.5.5 and 6.1. See the
-[upstream dependency contract](https://github.com/espressif/esp-brookesia/blob/6a087b6d76e989802b72fdb835928b273af76af8/utils/brookesia_lib_utils/idf_component.yml).
-
-For the local clone layout in the [quick start](../README.md#quick-start), add
-this dependency to the application's `main/idf_component.yml`:
-
-```yaml
-dependencies:
-  brookesia_hal_custom:
-    override_path: ../components/waveshare_boards/integrations/brookesia_hal_custom
-```
+The helper accepts 0–100 percent, clamps values above 100, and sends the original
+QSPI brightness command (`0x51`). It returns `ESP_ERR_INVALID_ARG` for a null IO
+handle and propagates LCD IO errors. Zero sets brightness to zero.
 
-Merge it with existing dependencies. Resolve dependencies, select the matching
-AMOLED board, and build the application. Do not add this adapter dependency to
-`board_devices.yaml`. Explicit component selection registers the plugin under
-its original name; applications use their normal HAL interface lookup.
-
-The adapter directly uses `brookesia_hal_interface` and Board Manager. It no
-longer includes the full `brookesia_hal_adaptor` solely for the `display_lcd`
-group constant. This keeps the standalone plugin independent of the adaptor's
-Board Manager version constraint.
-
-A complete Brookesia application still needs its own dependency review:
-[HAL adaptor 0.8.4](https://github.com/espressif/esp-brookesia/blob/6a087b6d76e989802b72fdb835928b273af76af8/hal/brookesia_hal_adaptor/idf_component.yml)
-requires Board Manager `0.5.*` when display is enabled, while this board pack
-requires `>=0.7.2`. That upstream constraint is not changed here. Passing the
-standalone interface-adapter test does not claim that an unmodified full
-Brookesia application resolves with this pack.
-
-## Preserved application profiles
-
-The original Brookesia application defaults are retained separately:
-
-```text
-integrations/brookesia_hal_custom/profiles/
-  esp32_s3_touch_amoled_1_75c/sdkconfig.defaults
-  esp32_s3_touch_amoled_1_8/sdkconfig.defaults
-  esp32_s3_touch_amoled_2_16/sdkconfig.defaults
-```
-
-They are opt-in reference configuration, not automatically appended board
-settings. They enable application features and refer to `partitions_16m.csv`,
-which the consuming application must provide. Choose the matching board profile
-and review it against that application's Brookesia version and partition layout.
-The ordinary hardware defaults remain beside each board.
-
-## Validation
-
-CI builds the plain board pack for all four boards on both IDF lines (eight
-builds), then separately enables this adapter for the three AMOLED boards on
-IDF 6.1 (three builds). This proves compilation and plugin linkage against the
-HAL interfaces. Host tests cover the public command encoding, percentage scaling,
-clamping, invalid handles, and IO-error propagation. CI also compiles the public
-header with both IDF lines. It does not exercise physical brightness changes or a full
-Brookesia application.
+The helper has no cached state or mutex. Applications that need a remembered
+brightness value or coordinate concurrent brightness changes manage that state
+and synchronization themselves. The panel's existing initial-brightness command
+and board power initialization are unchanged. RGB LCD boards do not use this
+QSPI AMOLED command.
 
-To compile the adapter with the repository's test app in a fresh checkout:
+## Supported profiles and validation
 
-```bash
-python ci/scripts/board_pack.py pin 0.7.2
-python ci/scripts/board_pack.py integration brookesia
-idf.py -C ci/test_app bmgr -b esp32_s3_touch_amoled_1_8
-idf.py -C ci/test_app build
-```
+This helper applies to the 1.75C, 1.8 V1, and 2.16 AMOLED profiles. See
+[board revisions](BOARDS.md) before selecting a hardware revision.
 
-Use `integration none` for the ordinary test mode. Both commands only modify
-the test application's manifest; do not commit generated test inputs.
+Host tests check the command encoding, percentage scaling, clamping, invalid
+handles, and IO-error propagation. CI compiles all four board profiles on
+ESP-IDF 5.5.5 and 6.1, including the public header, for eight builds in total.
+Physical brightness changes still require testing on the selected board.
 
-The implementation and profiles retain their upstream copyright and license
-notices. See [source attribution](BOARDS.md#source-licenses).
+The implementation retains its original copyright and license notice. See

-## Brookesia AMOLED 调光
-
-`integrations/brookesia_hal_custom/` 为 1.75C、1.8 V1 和 2.16 三个 AMOLED 型号
-提供一份共用适配，替代原来重复的三份亮度实现。板卡发现和硬件初始化使用 `boards/`，
-不会自动选择该组件。需要 Brookesia HAL 调光接口的应用可以显式接入。
-
-共用适配保留以下行为：
-
-- 设备名 `CustomDisplay`、接口实现名 `CustomDisplay:Backlight` 和显示分组 `display_lcd`。
-- `set_brightness()`、`get_brightness()`，百分比限制在 0–100，转换成面板的
-  0–255 亮度值，通过公共函数发送原有 QSPI `0x51` 命令。
-- 线程互斥、相同值不重复发送、错误返回与初始化行为。插件初始化亮度仍为 0%，
-  后续由应用设置亮度。`get_brightness()` 返回最近成功设置的值，不是从硬件读回。
-- 独立灯光开关接口仍返回不支持，与原实现一致。
-
-普通屏幕初始化保留原有的初始亮度命令。该插件负责框架接口适配，不替代面板或 PMU 驱动。
-
-## 应用显式接入
-
-可选适配使用 **ESP-IDF 6.1**。测试的 Brookesia HAL interface 和 lib_utils 均为 **0.8.2**。
-上游 lib_utils 0.8 要求 IDF **6.0 至 6.2**，无法在 IDF 5.5 下解析依赖。
-这一上游框架限制不影响普通板卡包，普通模式继续覆盖 IDF 5.5.5 和 6.1。
-依据见[上游依赖约定](https://github.com/espressif/esp-brookesia/blob/6a087b6d76e989802b72fdb835928b273af76af8/utils/brookesia_lib_utils/idf_component.yml)。
-
-采用[快速开始](../README_ZH.md#quick-start)中的本地克隆结构时，在应用的
-`main/idf_component.yml` 中增加：
-
-```yaml
-dependencies:
-  brookesia_hal_custom:

-```
+函数接受 0–100 的亮度百分比，将超过 100 的值限制为 100，发送原有 QSPI 亮度命令 `0x51`。
+IO 句柄为空时返回 `ESP_ERR_INVALID_ARG`，发送失败时返回 LCD IO 错误。
+设置为 0 时将亮度降至零。
 
-与已有依赖合并，解析依赖后选择对应 AMOLED 板卡，再编译应用。
-不要把这条依赖加回 `board_devices.yaml`。显式选择组件后，插件以原有名称注册，
-应用仍通过正常的 HAL 接口查询方式使用它。
-
-适配组件直接依赖 `brookesia_hal_interface` 和 Board Manager，不再仅为引用
-`display_lcd` 分组常量而包含完整的 `brookesia_hal_adaptor`，因此独立插件不受
-adaptor 的 Board Manager 版本约束牵连。
-
-完整 Brookesia 应用仍需单独核对依赖：
-[HAL adaptor 0.8.4](https://github.com/espressif/esp-brookesia/blob/6a087b6d76e989802b72fdb835928b273af76af8/hal/brookesia_hal_adaptor/idf_component.yml)
-启用显示时要求 Board Manager `0.5.*`，而本板卡包要求 `>=0.7.2`。
-本次没有修改该上游约束。独立接口适配编译通过，不代表未修改的完整 Brookesia 应用
-能与本组件包一起解析依赖。
-
-## 保留的应用配置
-
-原 Brookesia 应用默认配置按型号分别保留：
-
-```text
-integrations/brookesia_hal_custom/profiles/
-  esp32_s3_touch_amoled_1_75c/sdkconfig.defaults
-  esp32_s3_touch_amoled_1_8/sdkconfig.defaults
-  esp32_s3_touch_amoled_2_16/sdkconfig.defaults
-```
-
-这些是按需采用的参考配置，不会自动追加到板卡配置中。
-它们会启用应用功能，并引用由应用提供的 `partitions_16m.csv`。
-选择对应板卡配置后，需要结合应用的 Brookesia 版本与分区表核对。
-普通硬件默认配置仍保存在各板卡目录。
-
-## 验证范围
-
-CI 对四块板卡在两个 IDF 版本线上运行普通模式编译，共八项；
-另外在 IDF 6.1 上为三个 AMOLED 型号启用独立适配，共三项。
-它验证 HAL 接口的编译与插件链接。主机测试覆盖公共函数的命令编码、百分比换算、
-范围限制、无效句柄和 IO 错误返回；CI 也会在两个 IDF 版本线上编译公共头文件。
-这些检查不替代实机调光或完整 Brookesia 应用测试。
+函数不缓存状态，也不持有互斥锁。需要记忆亮度值或协调多个任务调光的应用，
+应自行管理状态和同步。面板原有的初始亮度命令和板卡电源初始化保持不变。
+RGB LCD 板卡不使用这条 QSPI AMOLED 命令。
 
-在干净副本中，通过仓库测试应用编译该适配：
+## 支持配置与验证
 
-```bash
-python ci/scripts/board_pack.py pin 0.7.2
-python ci/scripts/board_pack.py integration brookesia
-idf.py -C ci/test_app bmgr -b esp32_s3_touch_amoled_1_8

+函数适用于 1.75C、1.8 V1 和 2.16 AMOLED 配置。选择板卡前请核对[硬件版本](BOARDS_ZH.md)。
