While working on the next release of PixelMaestro, I came across a problem of storing long-term data on an Arduino. I have a system in place where configuration changes are sent to an Arduino over USB as byte arrays, and as the Arduino reads the array it applies the changes. The problem is those changes disappear as soon as you restart the device. How, then, does one store persistent data without having to add an SD card or extra memory? Enter EEPROM.
In an earlier post, I explained how I used version control software to manage my creative writing documents. Since then, I’ve developed a setup that’s more transparent, easier to work with, and requires less command-line wizardry.
In an earlier post, I explored the idea of productivity gamification and how it can help increase your motivation. I’ve been testing this over the past few weeks by using an Android app called LifeRPG to track my habits, tasks, and important milestones I wanted to reach. In this post, I’ll go into detail about my LifeRPG setup and how it’s helped me stay focused in my everyday life.
On today’s episode of “Adventures in C++”: sending commands between two Arduinos running the same software. Not just data, but also instructions on how to process and execute that data. Even more, these commands have to be small enough for each Arduino to package, send, receive, unpack, and execute in less than 1/10th of a second.
One of the coolest things about C++ is how flexible the language is. If you’re faced with a problem that has no apparent solution, chances are you’re just not approaching it from the right angle.
When I first started this blog, I was just dipping my toes back into the world of C++. Before that, my experience with it was mostly academic, and after struggling through a course with a particularly poor professor I swore off it in favor of VB.NET. No, I never did forgive myself for that decision, but it ultimately helped me learn to appreciate the importance and relevance of C++. And after tinkering with systems that use C++ exclusively, I’ve come to appreciate it even more.
There’s a movement underway to transform the way we interact with personal computers. As computers become more automated and more intelligent, consumers are losing access to the software that makes them tick. The emphasis is moving away from computers as a platform and closer to computers as an appliance. What does this mean for end-users, and what does it mean for the future of our digitally dependent society?
