At Barr Group, our mission is to help embedded systems engineers make their products safer, more reliable and more secure. In addition to providing Training, Consulting, and Product Development services, our engineers share their technical expertise via webinars. We hope that you will learn something from these free how-to webinars. Please respect the copyright notices at the bottom of each page.

How to Prioritize RTOS Tasks (and Why It Matters)

Presented by Barr Group Principal Engineer Salomon Singer, this webinar examines best practices for assigning fixed priorities to a set of real-time operating systems (RTOS) tasks and interrupt service routines (ISRs). Viewers will learn how and why to use optimal methods to allow a critical set of tasks and interrupt service routines to meet all of their deadlines – even during transient overload periods. Lessons learned can be applied to the development of any priority-based preemptive RTOS, including real-time Linux.

How to Prevent and Detect Stack Overflow

The safety and security of every embedded system is dependent upon proper operation of the stack (or stacks, if there are multiple). If a stack overflow occurs, a major or minor malfunction is very likely to follow. Despite this, the stack in the majority of embedded systems is sized based on nothing more than a hunch. As well, run-time stack monitoring is too seldom used.

How to Get Started with C++ in Embedded Systems

C++ compilers are available for most modern embedded processors, yet the adoption rate remains low. Here we provide very practical advice to help you can get started with C++ immediately. The discussion moves quickly from dispelling common C++ myths and identifying key C++ benefits to a set of practical tips and tricks to help you put C++ to the most effective use in your "first month" and "first year."

Results of Barr Group's 2016 Safety & Security Survey

Barr Group's 2016 Embedded Systems Safety & Security Survey had participation from more than 2,500 embedded systems design engineers and revealed a number of interesting trends in the embedded industry. In this webinar, Barr Group executives Michael Barr (CTO) and Andrew Girson (CEO) discussed some of the most interesting findings.

How to Prevent Bugs in Embedded Software with TDD

It’s a fact: When you create code, you create bugs. Listen in as we present the finer points of Test-Driven Development (TDD) - a game-changing approach to embedded software development that can greatly reduce bugs early in the development process. TDD is not a debugging technique but rather an approach to proactively preventing defects.

How to Make Embedded Software Smaller and Faster

We've all heard it before - "premature optimization is the root of all evil" - yet many embedded systems have reliability, cost, and performance requirements that demand a development style where we optimize early and often. Performance needs to be designed into a system, from architecture to algorithms to data structures to coding guidelines.

How to Find and Fix the Most Common Embedded Software Bugs

As if debugging traditional PC/server software or even smartphone apps wasn't hard enough, debugging embedded software adds significant challenges. This webinar introduces you to some of the most common embedded software bugs and teaches you how to find/fix/prevent them.

Mutexes and Semaphores Demystified

What's the difference between a mutex and a semaphore? Even very experienced firmware developers too often fail to fully appreciate the importance of using the correct tool for the job at hand. And, unfortunately, misuse of these two distinct types of synchronization primitives can lead to difficult to debug defects in embedded software, with potentially severe consequences in safety-critical medical devices, avionics and transportation equipment.

Pros and Cons of AndroidOS for Embedded Systems

In this webinar we discuss an overview of Android software architecture, hardware requirements, licensing terms, and security considerations. We also examine a few case studies which illustrate the pros and cons of building embedded systems around the Android operating system.

Hardware-Software Partitioning in Embedded Systems

One of the biggest challenges when architecting an embedded system is partitioning the design into its hardware and software components. Partitioning decisions must typically be made early in the design of a product. The consequences of hasty or biased decisions or lack of proper analysis can include, in the worst case: higher BOM cost, time-to-marked delays, or even an inability to meet requirements.
