280 SDK Platform Services

The 280 ST/QT-SDK includes configurable 280 Platform Services designed to support the target application. These services form part of the SDK’s middle layer, positioned above the MCAL layer, as shown in the diagram below:

Configuration Overview

All Platform Services configuration options are defined in the 280_Config.h header file, located under the user_modify_files folder within the SDK project structure:

Purpose of the Configuration File

The 280_Config.h file allows developers to customize display-related settings for their specific application requirements. Examples of configurable parameters include:

  1. Input selection and mapping

  2. Display type and resolution

  3. Sampling rate

  4. Debouncing options

These settings apply regardless of whether you are using 280 ST-SDK or 280 QT-SDK.

Note: The configuration file only affects Platform Services. Customization of display screens, navigation, and overall look and feel should be performed using TouchGFX (for ST-SDK) or Qt Creator (for QT-SDK).

Applying Configuration Changes

To apply updates to the Platform Services configuration:

  1. Rebuild the SDK project using STM32CubeIDE.

  2. Reprogram the target unit with the newly built firmware.
