Embedded
Borrowed from the natural realm, the term ecosystem has become a popular – some say overused – buzzword in the tech world, though there’s no consensus about its precise meaning. Some think of an ecosystem as a group of appliances and devices designed to work harmoniously together, creating a…
BlogContinuing our series on building with CMake, in this installment we’re taking a look at how to create a library that others can use for their own applications. (If you missed the earlier installments, part 1 shows how to make a simple application, while part 2 explains how to find libraries to use…
BlogFor most of our work on embedded devices, the setups are typically quite static: the main board, a display with known resolution, some sensors. But sometimes there is a requirement that shakes up the status quo. On one recent project, that was definitely the case. The customer said “We have…
BlogIn this second installment of our series on FreeRTOS, we take a more detailed look at its key features, supported platforms, licensing and cost. I'll also note other variants of FreeRTOS, as well as some add-on tools and libraries. In contrast to a full operating system,…
BlogYou just shipped your impressive new product, built on the latest System on a Chip (SOC) from XYZ Microsystems. You chose this SOC because it decreased your parts count and reduced your manufacturing bill of materials. And with its fast CPU, this SOC powers your product to process four times as…
Blogfigure {max-width:600px; margin-bottom:25px} I just got back from a very successful Qt World Summit 2019 in Berlin. This year marked a much-appreciated return to the traditional two-day conference schedule (with a third, optional training day). Last year's shows in Boston and Berlin had a…
BlogThe market for embedded software development is one of the fastest growing areas of computing. But as the market grows, so too does the complexity of the devices. At a time when manufacturers are demanding more sophisticated "iPhone like" user interfaces and greater product functionality, today’s…
BlogThis blog is the third in an occasional series on ZeroMQ. For background, read part 1 and part 2. ZeroMQ encourages us to think in terms of patterns — what we are going to do rather than how we're going to do it. We don't need to worry about the how since ZeroMQ takes care of it. …
BlogThis blog is part of a continuing series on GPIO programming. If you missed earlier installments, find them here. In this post we'll look at a representative embedded board, one that we use for our embedded training classes and that we have used on a number of customer projects. Toradex [1] is a…
BlogIn this blog post we'll look at how to control Raspberry Pi GPIO pins from the Python programming language using two different modules: Rpi.GPIO and Gpiozero. A Bit About Python Python [1] is an interpreted, high-level, general-purpose programming language that has been around since 1991. It is…
BlogIn the past, embedded systems often ran very small operating systems with no filesystem, or even ran on the "bare metal." With the increasing power and lower cost of hardware, including SOCs (Systems on a Chip), many embedded systems are moving to a full operating system, often based on Linux…
BlogNearly half of all companies in the US using an Internet of Things (IoT) network have been the victims of at least one security breach. Forty-eight percent. That’s according to a recent survey of 400 IT decision-makers across 19 industries conducted by strategy consulting group Altman Vilandrie…
BlogGet Qt Running on Your Embedded Platform Quickly and Painlessly Software often ends up being the final barrier before a new product with embedded hardware can be released to manufacturing. The Qt® framework helps reduce the magnitude of this barrier by allowing the development of embedded…
Basic pageI've mentioned the Yocto (1) embedded framework in previous blog posts. Some people may have shied away from trying it because they have heard it has a steep learning curve. While Yocto is complex, it is very easy to get started and you can do so without any embedded hardware. In this post I'…
BlogGumstix Verdex Pro (XScale™) ICS used Verdex Pro as a performance test bed for a client that was developing a custom board with the Marvell® PXA270 processor. This project called for ICS to port Qt 4.5 to the embedded platform, validate the port, and assess its CPU performance and memory…
Basic pageThe Raspberry Pi (1) is one of the more popular low-cost computers on the market. It has an ARM CPU, hardware video acceleration, RAM, SD card mass storage, and almost everything that a regular desktop computer has to offer at a fraction of the size and cost. It also has a set of GPIO (General…
BlogQtSerialBus is a new Qt module, introduced as a technical preview in Qt 5.6.0. It supports two serial interface protocols that are commonly used on embedded systems: CAN bus and Modbus. In this blog post we'll take a brief look at this new module and what it provides. What is CAN bus? CAN bus (1…
BlogEmbedded World Exhibition & Conference will be held February 23-25 in Nuremburg, Germany. Each year the embedded world Exhibition & Conference offers the embedded community the opportunity to obtain information about new products and innovations, enter into an exchange and to maintain and…
Basic pageInspired by Halloween, I'd like to present a list of ten "scary" mistakes using Qt. Based on the wide experience of ICS with Qt consulting projects, I have provided a list of errors that can doom any project. 1. Waiting too long to test on hardware One of Qt's strengths is its…
BlogThe Raspberry Pi 2 computer, released in February 2015, is the latest generation of Raspberry Pi hardware. It is a significantly faster machine than the original Raspberry Pi, with a new Broadcom BCM2836 system on a chip that has a quad-core ARM Cortex A7 CPU running at 900 MHz. The GPU is a…

Basic pageAs the year draws to a close, I thought it would be good to take a look back at some of the major events of the Qt world in 2014. Qt is now on a regular schedule of two major releases per year. We saw Qt 5.3.0 (1) come out in May and Qt 5.4.0 (2) in December. More minor releases occur, as needed,…
BlogSince my last blog about the Raspberry Pi in August, there have been a number of interesting new developments and the Raspberry Pi project has continued to move ahead. As expected, the new Raspberry Pi Model A+ was released. With the Model A+, the Raspberry Pi Foundation has been able to achieve a…
