The BSP repository includes a lot of LCD and Touch driver components. The list of available and planned LCDs is here.
We offer seamless integration of LVGL graphical library into esp-idf applications in LVGL port component.
Moreover, LVGL port includes recommendations and tips for increasing graphical performance.
Best way to start with ESP-BSP is trying one of the examples on your board. Every example contains README.md with a list of supported boards. Here is the summary of the available examples:
| Example | Supported boards | Try with ESP Launchpad |
|---|---|---|
| audio | ESP32-S3-Korvo-2 | Flash audio |
| display | WROVER-KIT | Flash display |
| display_camera | Kaluga-kit | Flash display_camera |
| display_audio_photo | ESP-BOX | Flash display_audio_photo |
| display_rotation | ESP-BOX | Flash display_rotation |
| display_lvgl_demos | ESP32-S3-LCD-EV-Board | Flash display_lvgl_demos |

bsp/name-of-the-bsp.h: Main include file of the BSP with public APIbsp/esp-bsp.h: Convenience include file with the same name for all BPSsbsp/display.handbsp/touch.h: Only for BSPs with LCD or touch controller. Contain low level initialization functions for usage without LVGL graphical library- By default, BSPs with display are shipped with LVGL, if you are interested in BSP without LVGL you can use BSP versions with
noglibsuffix (eg.esp32_s3_eye_noglib).

NOTE: There can be only one BSP in a single esp-idf project.
Packages from this repository are uploaded to the IDF component registry.
You can add them to your project via idf.py add-dependency, e.g.
idf.py add-dependency esp_wrover_kit==1.0.0
When you want to use a BSP in a real project, it is highly recommended to disable configuration option CONFIG_BSP_ERROR_CHECK in menuconfig. You should check all returned error codes from all BSP functions you call. Otherwise, if the option CONFIG_BSP_ERROR_CHECK is enabled, any error encountered in a BSP will abort the program.
ESP-IDF v5.0 brings a lot of new features, but, as the bump in major version suggests, also a lot of breaking changes.
ESP-BSP is kept up-to-date with the latest ESP-IDF version, but some breaking changes in ESP-BSP API are inevitable.
Usually, BSPs compatible with IDF v5.0 are version 2. If you want to use BSP with IDF v4.4 you can still use version 1 of the particular BSP.
If you are interested in BSP examples for IDF v4.4, you can git checkout tag examples_v4.4.
More information about ESP-IDF breaking changes can be found in the official migration guide.
⚠️ Experimental feature: This feature is under development!
A single project can be run on multiple different development boards, if the boards contain the features required by the project (such as audio, display, camera...).
For this purpose, idf.py is extended by examples/bsp_ext.py which allows you to build an example for your specific BSP. Example command for display e.g.:
idf.py -D SDKCONFIG_DEFAULTS=sdkconfig.bsp.esp_wrover_kit build
In case you want to build locally for multiple boards at the same time, it is useful to have separate build directories for each BSP configuration. In order to achieve this, you can extend the above command like this:
idf.py -B build/wrover_kit -D SDKCONFIG_DEFAULTS=sdkconfig.bsp.esp_wrover_kit build
Note: This feature is not yet integrated to idf.py by default. If you want to use it, you must set your environmental variable
IDF_EXTRA_ACTIONS_PATHto path toesp-bsp/examples/bsp_ext.py.
Please check CONTRIBUTING.md if you'd like to contribute to ESP-BSP.
Also check BSP Development Guide to find out more about BSP API and architecture.
