Introduction

The 280 Instrument Display is designed to provide a responsive embedded system for delivering a reliable instrument and control interface. This document introduces the 280 ST/Qt Software Development Kit (SDK) for the 280 Instrument Display powered by the STM32H743II microcontroller, leveraging STM32CubeIDE and the GNU Tools for STM32 toolchain for firmware development, alongside TouchGFX or Qt for MCU for advanced graphical user interface (GUI) design.
