I need to be clear that this post is aimed at engineers (particularly embedded systems developers) who have signal processing, data analysis, and visualization work to do as a secondary part of their job.įor those of you who are doing full-time, hardcore signal processing or control systems design, MATLAB is probably the right tool for the job. But first, a caveat: We do need stinkin' MATLAB?! Here are some examples of what it can do. Don’t be a one-trick pony and get stuck in C and assembly development for your favorite processor of choice!Īnyway, there’s lots of times when I have to stop programming and try out the theory of some idea I have. Because you need to expand your horizons. So if you’re using Python, you’re not really doing embedded system development. There’s a compiler that runs on your system, so you don’t need a cross-compiler.You have an operating system with a command shell.Signs You Aren’t Working on a Resource-Limited Embedded System: Hold on a minute - this is an embedded systems blog, right?! Python won’t run on a resource-limited embedded system, and in fact Python is one of my three criteria…. scipy for scientific and engineering applications.numpy for fundamental numerical analysis (vectors, matrices, and scientific functions that operate on them).matplotlib for graphing and data visualization.PyLab is a Python environment for scientific computation that includes the following packages: Scilab, Octave, Sage… all were kind of flaky, and didn’t seem to have the features and richness I wanted. This article is available in PDF format for easy printing :–) So I started looking at alternatives. But my group only has it available on a shared laptop. This post will be a short tour of PyLab, and a springboard for a number of other topics - including that long-awaited sequel to encoder speed estimation.Īt work, we use MATLAB as data analysis and visualization software. OK, now back to some down-to-earth topics after that last philosophical diversion. Please note this represents opinions that are my own, and do not reflect those of my employer or of this website’s publisher. While I don’t make it a secret of my dislike of many aspects of MATLAB - which I mention later in this article - I do hope they can improve their software and reduce the price. Author’s note: This article was originally called Adventures in Signal Processing with Python (MATLAB? We don’t need no stinkin' MATLAB!) - the allusion to The Treasure of the Sierra Madre has been removed, in deference to being a good neighbor to The MathWorks.
