Steps on Raspberry Pi : 1) Install pyQt : $ sudo aptitude install pyqt4-dev-tools 2) Install pip $ sudo aptitude install python-pip 3) Install pyFirmata $ sudo pip install pyfirmata 4) Download qtgui02.py (Based on qtgui.py) $ wget https://www.binefa.cat/php/raspberryPi/python/pyQt/qtgui02.py.tar.gz $ tar -zxvf qtgui02.py.tar.gz Steps on Arduino : 5) Install standard firmata on Arduino 6) Mount Arduino Nano… Continueu llegint Arduino + Raspberry Pi using pyFirmata and pyQt

Serial read using Ardublock

SCoop + Ardublock

First two options are not optimal because event are detected after delays. The last two options are using SCoop Sleep instead of delay. The last two options are better than the first ones. SCoop should be installed at Arduino IDE

SCoop installation on Arduino IDE

SCoop : Simple Cooperative Scheduler for Arduino and Teensy ARM and AVR 1st option) Go to official SCoop website : https://github.com/fabriceo/SCoop/ and follow its instructions 2nd option) Once Arduino IDE is installed on Debian, download https://www.binefa.cat/arduino/ardublock/SCoop.tar.gz at /usr/share/arduino/libraries and uncompress it. clot@debian:/usr/share/arduino/libraries$ wget https://www.binefa.cat/arduino/ardublock/SCoop.tar.gz –2014-11-18 17:26:30– http://www.binefa.cat/php/arduino/ardublock/SCoop.tar.gz S’està resolent www.binefa.cat (www.binefa.cat)… 37.58.75.228 S’està connectant a… Continueu llegint SCoop installation on Arduino IDE

How to recover bricked fake FT232

First off, I’m against piracy in software and hardware. I understand FTDI trying to protect themselves from piracy and fake replicas. Having said that, clearly, end users have bought electronic products legally and most of them are out of warranty because they had bought them years ago. End users can blame and complain to their… Continueu llegint How to recover bricked fake FT232

Arrencant Debian des d’una memòria USB

Aquesta és una imatge del sistema operatiu Debian pensat per a explicar programació als cursos de robòtica i informàtica a l’Escola del Clot – Jesuïtes El Clot. Per aquesta raó el nom d’usuari, contrasenya d’usuari i contrasenya de l’usuari primari és clot.

Arduino’s VU-meter using ArduBlock

This is chapter 3 about using Ardublock . It reads an analog value from a potentiometer and it writes to 8 leds VU-meter style. (link)

Ultrasound Distance Measurement

This is chapter 2 about using Ardublock . It starts reading distance from ultrasound sensors and showing it on Serial Monitor. It follows with an improvement adding an LCD. (link)
