IN Brief:
- GigaDevice and Qt Group are optimising Qt for MCUs on the GD32H7 platform.
- The collaboration includes reference designs, software frameworks, training, and customer enablement.
- Embedded HMI development is becoming more demanding as industrial systems add richer local interfaces.
GigaDevice and Qt Group have formed a partnership to improve embedded graphical user interface development on GigaDevice’s GD32H7 high-performance microcontroller family.
The companies will optimise and validate Qt for MCUs on the GD32H7 platform, supported by reference designs, software frameworks, application guidance, training, and developer enablement. The work is aimed at systems where richer local interfaces must run within tight processor, memory, power, and cost limits.
The GD32H7 series is based on an Arm Cortex-M7 core running at up to 600MHz. The family includes high-speed connectivity, industrial interfaces, multimedia processing features, TFT-LCD controller support, image-processing acceleration, high-speed ADCs, Ethernet, CAN-FD, USB, and EtherCAT SubDevice Controller options.
Those features place the devices across industrial control, HMI, energy storage, motor control, machine vision, robotics, and connected embedded systems. Qt for MCUs adds a more structured GUI development environment to that hardware base, giving engineers a validated route for building responsive interfaces without moving automatically to a higher-power application processor.
Industrial interfaces have become more demanding. Many embedded products now need displays that behave more like modern software environments, while retaining the reliability, boot time, lifecycle support, power budget, and deterministic behaviour expected from microcontroller-based systems. The display stack can no longer be treated as a cosmetic addition late in the design process.
Pre-integrated support can reduce friction during early evaluation, where teams often spend considerable time proving that graphics, memory usage, timing, input handling, peripherals, and real-time tasks can operate together. A validated MCU and GUI framework combination gives development teams a more reliable path from prototype to production.
Software access is now influencing silicon selection as directly as hardware specifications. Infineon has also moved MCU evaluation into a cloud-based workflow with AWS, giving developers a route to test automotive microcontroller software before physical hardware arrives. The GigaDevice-Qt collaboration reflects the same shift from component selection towards ecosystem selection.
High-performance MCUs increasingly compete not only on clock speed, memory, package choice, and peripheral mix, but on toolchains, middleware, reference software, security support, community resources, and long-term maintainability. A microcontroller that is technically suitable can still lose a design if the software path is too slow or too uncertain.
The pressure is particularly visible in HMI design. Factory equipment, laboratory instruments, energy systems, robotics, and building controls are expected to support clearer visualisation, touch interaction, multilingual layouts, remote updates, diagnostics, and configuration tools. Delivering those capabilities on an MCU requires careful handling of memory allocation, rendering performance, interrupts, and real-time scheduling.
Moving to an application processor can solve some graphics challenges but brings others, including higher power, more complex software stacks, additional memory, operating-system maintenance, security exposure, and often a higher bill of materials. A stronger MCU-based GUI route gives designers another option where real-time control and polished local interaction must coexist.
The partnership strengthens the GD32H7 ecosystem while extending Qt for MCUs across another industrial-grade microcontroller platform. Embedded systems are becoming more visual, more connected, and more software-defined, and the development tools around the processor are increasingly part of the product architecture rather than an afterthought.
