Recently, for my IMU (Inertial Measurement Unit) project, I had the necessity to add low-pass filter, in order to reduce the noise on the accelerometer sensor signal. For this purpose, I decided to use a 1st order IIR (Infinite Impulse Response) filter, because it is easy to implement and run on a microcontroller. In general, … Continue reading "How to calculate a first order IIR filter in 5 minutes"
This guide simply explains how to flash an "ino" sketch on your Arduino Uno/Nano or similar, using Arduino IDE. For this guide, I used a chinese Arduino Nano clone equipped with CH340 USB-to-UART adapter. This guide is also applicable for flashing Fuelino software into Fuelino hardware (such as Fuelino Proto3). Before performing the following steps, … Continue reading "Arduino Nano sketch flashing with Arduino IDE"
Recently, I found a method to flash a "hex" file into Arduino Nano, by using "avrdude" running on a Raspberry Pi. In my case, I have an Arduino Nano connected, via USB, to a Raspberry Pi 3 B. The Raspberry Pi is connected to my home network using an Ethernet cable. I am developing the … Continue reading "Flashing Arduino with avrdude using Raspberry Pi shell"
This guide explains how to use Fuelino Log File Converter to convert the binary data logged by Fuelino, into easily understandable CSV files, which can then be post-processed using Excel or Mathworks Matlab or similar tools. The first step is to download the latest version of the Log File Converter from the Fuelino Project page. … Continue reading "How to use Fuelino Log File Converter"
A new version of Fuelino Calibration Tool is available on the Fuelino Project page. From a graphical point of view, this new "1.0 beta 2" version is similar to the previous one. Some modifications have been implemented to adapt it to the most recent software for Fuelino Proto3. After opening the EXE file "SimpleSerial.exe", the … Continue reading "Fuelino Calibration Tool 1.0 beta 2 released"
