Finding the right (Q)SPI Flash for your project

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 […]

IoT Station#1 Launched (using emMQTT)

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 […]

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

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 […]
