Instead, we had to use a small number, M, of individual sensors, each tuned to a specific wavelength.Īs my favorite professor used to say, “conceptually, there's no problem.” IfĪnd the signatures of the unknowns are unique, the problem is solvable.

We couldn't afford either the time or equipment to do a full spectrographic sweep. The concentrations were not constant-they varied with time-and the response of the system had to be fast-much too fast for the usual approaches. Naturally, the project being an embedded system, we had the usual gang of mutually exclusive goals: the system had to be small, cheap, fast, and finished yesterday. Conceptually, the problem is the same one chemists solve using a mass spectrometer. The approach was to pass white light through the solution, and try to identify the spectrographic signatures of each compound. The challenge is to identify both the type and concentration of N compounds in a solution, based on a spectrographic analysis. I'll change a few names to protect the innocent (mainly me).
#Designsoft tina 10 series
The problem that really motivated this series was one I ran across about three years ago, and it was indeed a real-time problem. It seems that all my problems really are nails-nails of a very specific sort, namely, nails that respond to minimization. Lately though, I've been on the other side of that coin. That way, when faced with a new problem, you'll be able to whip out the tool that works best. The whole purpose of the column is to provide you with a toolbox loaded with as many embedded programming tools as possible.
The old saying goes, “To a person whose only tool is a hammer, every problem looks like a nail.” The first time I quoted that saying was when I started writing this column back in 1994. Regular readers already know, but it has been a long time, so perhaps a refresher course in motivation is in order.
That's a fair question, and it deserves a valid answer. One writer asked why I'm thinking about minimization at all, since most embedded programs don't need or use it. No doubt, some of you newcomers who've only seen the last few issues must be thinking, “What's with this guy? Is minimization the only problem he ever thinks about?” I've gotten some e-mail asking me that very question. So fasten your seat belts, get ready for a bumpy ride, and I'll try to make this as fast as possible. However, this month, though I still very much want to finish off minimization, I feel the uncontrollable urge to ramble. In most of my recent columns, however, I've wanted so much to put this business of minimization to bed that I've restrained my usual tendency to ramble, and tried to stick to the discussion at hand. In the past, I've touched on everything from the Great Pyramid to my experiences with Dell, to good guys and (other) bad guys, to toy robots, to what's wrong with the world today. Regular readers know that I often ramble a bit, discussing things that are mostly off topic.
Other interesting Linux alternatives to TINA are QUCS (Free, Open Source) and LibrePCB (Free, Open Source).Despite making every effort to avoid it, Jack keeps running into new problems with minimization at the heart of the solution. If that doesn’t suit you, our users have ranked 46 alternatives to TINA and 14 are available for Linux so hopefully you can find a suitable replacement.
#Designsoft tina 10 free
It’s not free, so if you’re looking for a free alternative, you could try KiCad or Circuit Simulator. The most popular Linux alternative is Fritzing. TINA is not available for Linux but there are plenty of alternatives that runs on Linux with similar functionality. TINA Design Suite is a powerful circuit simulation package for analyzing, designing, and real time… Created by DesignSoft, Inc.
