Ricardo Anguiano Stella, our Nucleus powered, self-balancing robot generates kernel and application level trace data which is then visualized using Sourcery Analyzer. Arvind Raghuraman, Staff Engineer on the Nucleus RTOS team and creator of Stella, will give you a tour of Stella’s application layer trace visualization. Arvind previously instrumented Stella’s relevant application layer variables including … Read More

Ricardo Anguiano Stella, our Nucleus RTOS powered, self-balancing robot generates kernel and application level trace data which is then visualized using Sourcery Analyzer. Sourcery Analyzer is used to detect and explore wheel angle bias, and test the hypothesis that perhaps the corrective pulse width signals are causing the wheel angle bias. We also use the measurement tool to quantitatively characterize the worsening … Read More

Medical Device User Interfaces

Posted by Phil Burr

Phil Burr How many times have you tried prodding at the screen of a device and only after it has failed to respond have you remembered that it isn’t actually a touch screen? I know that I have done this, and after talking to a friend of mine who is a doctor in my local hospital, I am pleased to know that I am not the only one! It is no surprise that the medical profession’s expectations of user interfaces has … Read More

Jamie Little   Since the Nucleus Innovate Program was launched in November of last year, we’ve recieved dozens of Qualification Forms and many small companies have been approved for free licenses. While the popularity of the program has been exciting, the array of customer applications we’re seeing from the Innovate Program is equally as exciting! For example, some of the market segments represented … Read More

Munich conferences

Posted by Colin Walls

Colin Walls I attend quite a few conferences, taking any opportunity to speak about embedded software matters. Although such events take place throughout the year, there are two notable periods: Summer [July/August], when everything goes very quiet, and early Fall [late September and October], when everything goes mad. We are just beginning the “quiet” period. But there were a couple of events scheduled … Read More

How long is a piece of string?

Posted by Colin Walls

Colin Walls Answering questions is something that I am often expected to do. Maybe I am presenting at a conference, doing an online seminar, hanging out on a trade show booth, writing blogs or articles – these all elicit questions. Sometimes I am asked by a salesperson to respond to a customer’s question. I would always do my best to give a complete and accurate answer and certainly aim to be truthful. … Read More

Ricardo Anguiano So, what sorts of things can you create with Mentor Graphics’ embedded software development tools and platforms?  How about a self-balancing robot named Stella?  The Nucleus ReadyStart development platform, which includes the Nucleus RTOS, Sourcery CodeBench IDE and toolchain and Sourcery Analyzer performance and analysis tool, was used in the development of Stella. Stella the robot is an inherently … Read More

SEP 2.0

Posted by Colin Walls

Colin Walls When I first heard the term “Smart Energy”, I confess that I had no idea what it meant. For a while, a precise definition seemed to elude me, as people would talk about smart meters and the Smart Grid, but not actually say what smart energy was. It is now a little clearer. Smart Energy is really a catch-all term for a bunch of technology associated with energy efficiency primarily in a domestic … Read More

Device Firmware Upgrade through USB

Posted by Colin Walls

Colin Walls One of the great things about software, compared with hardware, is the ease with which it may be changed and updated. The big downside of software is also the ease with which it can be changed. This ease can make software developers lazy, as they know that they can always fix things later. This is a sharp contrast to chip developers who are fearful of errors, as an ASIC respin is both time consuming … Read More

Using an SMTP client

Posted by Colin Walls

Colin Walls I always find it satisfying to see simple solutions to apparently complex problems and the world of embedded software certainly lends itself to some creativity. My concept of “simple” is quite broad, but essentially encompasses anything that is easy to understand [for me] and ideally avoids reinvention of any wheels. A while ago, I wrote about incorporating a Web server [HTTP server actually] … Read More

When an Innovative Plan Works!

Posted by Jamie Little

Jamie Little Free Nucleus RTOS source code? Just a few years ago if you would have told me that Mentor Graphics would be offering free-source-code for one of the most successful, popular and distributed RTOS’s in the world, I would not have believed it. Yet, for the last few quarters, Mentor is doing just that! The Nucleus Innovate Program was announced November 2012 and adoption is picking up quickly! To date, … Read More

Jamie Little In the high-tech market, the IoT is driving connectivity requirements in devices across many segments. Considering the number of embedded medical devices hospital, you can quickly imagine areas where Wi-Fi connectivity can be used to connect devices, patients, administrators and doctors. For example, Wi-Fi can be applicable in the doctor’s office, in the operating room, at the nurse’s station, in the … Read More

Anil Khanna Nucleus, our flagship RTOS offering has been around for several years now. In this time, it has been designed into more than 3 billion embedded devices in various applications such as mobile, medical, consumer electronics, industrial and more! The phrase “been there done that” could not be more appropriate to Nucleus. Regardless, when it came time to design yet another cool demo, our engineers were … Read More

What is an FPGA?

Posted by Colin Walls

Colin Walls In the early days of embedded systems, software engineers typically had some understanding of hardware design. Indeed, in many cases, it was the hardware designer who implemented the software. Over the years, as the amount of software development has increased, engineers have become less and less “hardware aware”. I find this transition interesting from the viewpoint of an embedded software … Read More

Debugging with printf() or not ...

Posted by Colin Walls

Colin Walls My colleague Richard Vlamynck [who has been a guest blogger here] and I were discussing tracing and debugging. Like me, he has been doing software for a few years. Hence, when we considered tracing and instrumenting code, he commented “It used to be easy to see what effect trace statements had on your program because, as you put more or less trace cards in your Fortran deck, you could visually … Read More
