Supported target boards and development hosts

Qt Quick Ultralite supports a variety of microcontroller-based hardware platforms that are available in the market. Currently supported boards are listed below. Select the board name in the table for information on how to get started with the board.

Qt for MCUs can be ported to any modern microcontroller that is capable of driving a display. If your hardware is not listed, contact us for an estimation of the porting effort, or follow the Qt Quick Ultralite platform porting guide to port Qt Quick Ultralite to this hardware.

Support levels for target hardware

There are multiple levels of support that apply across specific hardware and OS combinations.

Tier 1: Reference targets

Maintained for the entire 2.x series.
Covered by Standard Qt Support.
Releases are available via Qt Online Installer.

The reference target boards are listed in the following table, grouped by vendor.

Feature is supported by the platform adaptation
¹ Platform library has to be rebuilt
¹ Feature is supported by the hardware, but not implemented in the reference platform adaptation
² Feature is partially supported by the hardware, but not implemented in the reference platform adaptation
³ Blended as an image that is rendered by the CPU
⁴ Feature is supported by the hardware but self intersecting paths are not supported
⁵ Hardware blending via an intermediate ARGB8888 buffer
⁶ Accelerated blending when opacity != 1 is used
⁷ Source images are decompressed into small intermediate buffers chunk by chunk before blending
⁸ The reference board has limited available memory, so by default single buffering is used. This comes with a certain risk of visual flickering if the application contents are expensive to render
⁹ Single buffering is supported by the hardware, although it is likely to cause visual flickering. For this reason it's not implemented in the reference platform adaptation
¹⁰ Single buffering is supported by the hardware without any visual flickering, since the display contains its own framebuffer memory. It does however come with a significant performance cost. The reference platform adaptation needs modifications to enable the single buffering support
¹¹ The board families support 24 bpp and 32 bpp framebuffers, but the reference boards have only 16 lines physically connected to the LCD interface, so only 16 bpp is supported
¹² These color depths are available using the ItemLayer API, but not by using QUL_COLOR_DEPTH
¹³ TRAVEO T2G specific hardware accelerated RLE format is used
¹⁴ Feature is supported by software
¹⁵ Feature could be supported if the display has dedicated framebuffer memory, but it is not implemented in the reference platform adaptation
¹⁶ Currently only the LinuxFB render backend is supported, and an offscreen buffer is used in addition to the main framebuffer to reduce flickering artifacts.
¹⁷ Single buffering is enabled when DeviceLink is used but the buffer is split into parts before sending them to the display.
Feature is not supported by the hardware
HW is short for hardware accelerated blending
SW is short for software based blending

Supported target runtime environments and operating systems

With Qt for MCUs, applications can run on bare metal. Additionally, the following target runtime environments and operating systems are supported:

If you need to run applications on other target operating systems, contact Qt Group.

Supported development hosts

The development hosts supported by Qt for MCUs are:

Windows 10 64-bit
Ubuntu 22.04 LTS 64-bit

Running applications on host platforms

Qt Quick Ultralite applications can be run on host platforms to avoid having to flash the board too often and save time during development, or when a board is not available. The supported configurations are:

Operating System	Architecture	Compiler
Windows 10	x86_64	MSVC 2019, MinGW 11.2
Ubuntu 22.04 LTS	x86_64	GNU Arm GCC 10, GNU Arm GCC 11, GNU Arm GCC 12, GNU Arm GCC 13

If you need to run applications for other host architectures or operating systems, build and install a custom Qt platform library. See Building Qt Quick Ultralite platform library against the evaluation packages for more information.
