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 […]

Using AppWizard to create interesting buttons
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 […]
Creating a cool knob using the SEGGER AppWizard
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 […]
New office, more plans!
Things at SEGGER have been slower for the past three months or so. Or at least it may seem like that from the outside. There are two main reasons for this. First, we had a great summer and vacation season in Germany (as in most of Europe). Secondly, we have been busy planning, supervising construction […]
SMASH: an efficient compression algorithm for microcontrollers
One of the things that is driven from the top in SEGGER is that we can always do better. Not satisfied with standard schemes, we wanted to optimize emCompress, SEGGER’s compression library, for: Very fast decompression High compression ratio (uncompressed size divided by compressed size) Small decompressor Limited state in RAM when decompressing
The SEGGER linker and SOMNIUM assets
Startups come and go, some make it, some don’t. The embedded tools market is especially tough even for those that know it well, and being able to innovate and be successful needs true insight. To cut to the chase, SEGGER have acquired all intellectual property assets of SOMNIUM Technologies.
emNet with built-in UDP flood protection
emNet comes with many features already built-in. One of these features is a UDP flood protection that can help you to save execution time on incoming data that would be discarded anyhow. Whether you are really subject to an attack or you are simply part of a really crowded network, this optimization can free up […]
Using a watchdog in a multi-task (RTOS) environment
Clementine, a NASA satellite to test sensors and spacecraft components under extended exposure to the space environment, was launched on 25 January 1994. For the lack of a few lines of watchdog code, her mission was lost on 7 May 1994. Clementine had performed lunar mapping for approximately two consecutive months when she left lunar […]
Performance tuning our software
As you may have noticed, SEGGER have introduced a cryptographic algorithm library, emCrypt. We released this product as existing and new customers wanted to use the “hidden” cryptographic capabilities of emSSL but didn’t need to run SSL/TLS as a protocol. Well, that is not entirely true, some customers already had licenses for emSSL but also […]
Why you should benchmark your embedded system
There are plenty of potential reasons why an embedded system may not deliver the full CPU performance. This is not even that easy to detect, so here is a way to check if your system gives you the performance you expect. What can go wrong? Today’s embedded systems are complex computers. Microcontrollers are usually easiest […]
