Kind of Buggy! The state machine fantastic//
Over the years, I have had the opportunity to experience a lot of different kinds of coding mistakes. There were many that most programmers are familiar with, counting errors, indexing errors (the infamous 'off by one' bug), memory space sharing errors (A threading issue) as well as numerous others. I ran into one recently that I wound up using an old trick to help find.
My current project is a Pan/Tilt camera that was, upon occasion, not homing properly in one axis. The camera is a...
Tracing code and checking timings
Debugging resource limited systemsApplications writers that write code on large systems have it easy. Well, perhaps not easy, but certainly easier. There are some things that they don't have to worry about and there is a huge array of tools available to them when it comes time to debug. The have choices in their toolsets, lots of choices. They also have a large selection of available methods for getting debugging information out to them such as log files, proc entries, pop up dialog boxes or...
It starts with an LED
And slowly builds up from there.
I have been an embedded software engineer for many years. I was programming when I was a teenager before then, as a high school student involved in an NSF program called "National Science Foundation Summer Science Training Program (for High School Students)" or as we would rattle off during that summer of exquisite learning, NSFSSTP. We were taught to program in Fortran and taught the fundamentals of Calculus. It was a very enriching experience.
When it...
