PlainDSP (Part 1)

Part 1, 2, 3, 4 Among the most popular subjects covered in this blog, FFT is far ahead any other subject (22%!), followed by data acquisition functions. I got many, many requests for PlainFFT and PlainADC libraries and thanks to your explicit messages, I have a quite good understanding of who is using them and for which type of […]

Power Supplies (Part 1)

As long as you want to blink leds, everything’s fine with the power supplied by the USB cable. Here is a nice clean shield which could help you in fulfilling most power supply requirements.   The input voltage must lie in the 4.5 et 35 V range, and its output swings from 1.25 to 12V under 3A. It […]

Quadcopters

Part 1, 2, 3, 4, 5, 6 This post could be named at “Quadcopters and the magic wand” or “Quadcopters and the flying batons”. While watching this incredible new video, I was dreaming at a new ball game played with quadcopters, where quadcopter would flap a soft ball a little bit like volley ball, and throw […]

Getting started with the DUE (Part 2)

Part [-1, 0] 1, 2 I got a mail with an interesting question (Thanks Andrew!) regarding the performances of the DUE versus the UNO using PlainFFT.   I built this simple sketch based on the example which comes with the PlainFFT package: #include “PlainFFT.h” #include “math.h” PlainFFT FFT; /* Create FFT object */ /* Simulation parameters */ #define TWO_PI 6.283185307179586476925286766559 const […]
