If you need to speed up computations on your NetBurner module but don’t know where to start, you’re in the right place. During my intern project developing a 1/8-scale autonomous vehicle, I hit a brick wall when computationally intensive tasks started to fail. Instead of accepting that I had reached the limit of the board’s performance, I decided to buckle down and managed to decrease the runtime of computationally intensive tasks by an order of magnitude. This article will discuss the simplest things we can do to measure and improve performance. The provided code is designed to run on a NetBurner module but techniques discussed can be applied to any embedded development project.

Debugging code is often one of the biggest headaches that a programmer can encounter. This is especially true in the embedded systems world, where issues can live anywhere between the lowest level of hardware, to the highest level of application code. Code regressions that are the result of an unknown change in your commit history are especially difficult to track down. However, thanks to the simplicity and magic of "Git bisect", it will quickly become one of your favorite scenarios to debug. In particular, Git bisect is used to track down the exact commit that led to your broken repository state.

Debug like a Warrior. Part II

At NetBurner we do our best to deliver a turnkey experience that is easy, fast and as seamless as possible. Yet, there are times when you need to sharpen your sword and drive into battle against hordes of… Bugs! This doesn’t happen in most simple out of the box applications; however, one of the advantages with NetBurner is that we enable cavalier and experienced engineers to develop and tailor the embedded software to get customized functionality. This can sometimes introduce some less predictable and difficult-to-eradicate bugs, gremlins, goblins or demons. In this sequel, we’ll pick up with a few more techniques that will further train and empower you to recognize and exterminate those digital foes like a true warrior. If you missed the first part of this article you can catch up here.

Warrior’s Guide to Embedded Debugging - Part I

There is nothing more frustrating than having a problem and feeling helpless while some oracle on the other end of a nebulous contact form decides your fate. In the ideal world you would be able to solve your own problems without ever needing outside help, right? Our goal at NetBurner is to make the product in such a way that you rarely need support; not because we don’t want to help you, but to get you farther, faster. We still have a way to go and that’s why we take pride in the quality of our support, blog posts and community forums to fill those remaining gaps.
