I used to think that floating-point was not for Embedded Systems. Too slow, too much code overhead and rounding is always a problem. It turns out that while scaled integers still have a performance benefit, floating-point computations can be done with a surprisingly high performance these days on modern Embedded CPUs. This is true not […]
Not all SPI Flashes are created equal SPI Flashes have become very popular as an inexpensive way to add nonvolatile storage (flash memory) to an Embedded System. They come in various capacities, so increasing memory is fast and easy. Any microcontroller can interface to them via SPI or QSPI peripheral interfaces, or simple general purpose […]
In almost any area that invites comparison people want to know: “Who’s the best?” This goes for hotels, restaurants, manufacturers, and certainly sports teams. The embedded world is no exception. Except in the embedded world there is no contest or competition to decide a winner. The Good The embedded industry has a lot of good […]
What makes a great runtime library different from a run-of-the-mill runtime library? This article will answer some of those questions with hard data and technical insights.
Here’s more of “What’s cooking at SEGGER”. We were looking for a quick and easy way to demonstrate an integration of SEGGER’s software libraries, embOS, emNet, emSSL, emMQTT and the IoT Toolkit, with IoT cloud services, such as Amazon Web Services (AWS). Having the idea, the software, the hardware, and the expertise, all we needed […]
In my previous post, I described how to make a nice knob / dial using the SEGGER AppWizard. This time it’s all about creating some cool buttons. The AppWizard Button Widget The AppWizard, SEGGER’s new, still-under-development GUI builder tool, offers a variety of widgets. One of the is the Button widget. It allows adding a […]
FPGAs can do things that CPUs cannot do as quickly, or as efficiently, or simply cannot do at all. The bottleneck on rapidly expanding market usage for a powerful FPGA, with hard CPU cores, is that almost all applications use Linux. This requires a lot of memory, most of all RAM, and insufficient built-in RAM […]
This article documents the process of creating a decent-looking knob for an embedded GUI, using the new SEGGER AppWizard, which – at the time of this writing – is still under construction. I describe the hunt for suitable graphics, the tools I used to adapt them to meet my needs, and how I ended up with […]
This Easter Friday, I was surprised to see the message that Express Logic has been acquired by Microsoft. The announcements on the websites of both companies do not disclose too much information on how exactly things will continue to operate, but it seems that Microsoft has bought Express Logic because they want the software as […]
This article covers how SEGGER vastly improved its documentation process by taking control of the tools we use and, in the process, removed reliance on FrameMaker.
