## 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
1. Display type and resolution
1. Sampling rate
1. 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.
1. Reprogram the target unit with the newly built firmware.
