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. Click the board name in the table for information on how to get started with the board.

Reference Target Boards

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

Qt for MCUs ports for reference boards are:

  • maintained for the entire 2.x series,
  • upgraded to support all Qt Quick Ultralite features when possible,
  • covered by Standard Qt Support,
  • and available for download in Qt Online Installer.

Note: Other Target Boards list hardware that are ported to Qt for MCUs but are not part of reference platforms.

Other Target Boards

The following table lists hardware that are ported to Qt for MCUs but does not qualify as reference platform. These ports are not maintained for every Qt for MCUs release, which means they:

  • do not always include implementations of all Qt Quick Ultralite features,
  • and are not covered by Standard Qt Support.

You can get these ports from The Qt Company or its partner vendors.

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.

  • Feature is supported by the platform adaptation
  • 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 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
  • Feature is not supported by the hardware
  • HW is short for hardware accelerated blending
  • SW is short for software based blending

Supported Target Operating Systems

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

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

Supported Development Hosts

The development hosts supported by Qt for MCUs are:

  • Windows 10 64-bit
  • Ubuntu 20.04 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 SystemArchitectureCompiler
Windows 10x86_64MSVC 2017, MSVC 2019
Ubuntu 20.04 LTSx86_64GCC 8, GCC 9

If you need to run applications for other host architectures or operating systems, contact The Qt Company.

Services, Standard and Premium support

Qt offers product support at different levels in order to help you with technical challenges and to suggest best practices. See the Qt Support page for an overview about these different support levels. Also, see the License Agreements and Service Terms page for the latest version of the Qt license agreements and the support terms and conditions for the Qt account.

Support duration

A Qt for MCUs version is available under Standard or Premium support for a limited duration only. Since Qt for MCUs v2.0.0, regular and Long Term Support (LTS) versions (x.y.0) are supported for six (6) and eighteen (18) months respectively. The support duration for both regular and LTS versions begin from the release date.

If you need support for an older version that is out of support, purchase extended support. This lets you ask questions and report issues on that version.
