ESP-BSP: Espressif's Board Support Packages

LCD and TOUCH drivers

The BSP repository includes lot of LCD and Touch driver components. The list of available and planned LCDs is here.

How to use

Examples

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
display WROVER-KIT
display_audio Kaluga-kit
display_camera Kaluga-kit
display_audio_photo ESP-BOX
display_rotation ESP-BOX
mqtt_example Azure-IoT-kit
rainmaker_example Azure-IoT-kit
sensors_example Azure-IoT-kit

BSP headers

Each BSP provides its header file in 'bsp' subfolder, so it can be included as follows: #include "bsp/name-of-the-bsp.h".

For you convenience, each BSP also provides a wrapper header, which has the same name for all BSPs: #include "bsp/esp-bsp.h".

NOTE: There can be only one BSP in a single esp-idf project.

In a custom 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

Alternatively, you can create idf_component.yml file manually, such as in this example.

Recommendation for custom projects

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.

Migration to ESP-IDF v5.0

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.

More information about ESP-IDF breaking changes can be found in the official migration guide.

Additional information

More information about idf-component-manager can be found in Espressif API guide or PyPi registry.
