Measure the consumption of ST Nucleo

To measure the real consumption of the ST NUCLEO
We must:
1) Remove the IDD jumper (JP6 - highlighted in black and red)
2) On the left the negative pole on the right the positive pole (black and red colors)
3) set  multimeter to DC
4) Measurement ranges: mA  for STM32Fxx  family; μAfor STM32LXX family

Progetto gEDEA

Il progetto gEDA è una suite di strumenti per l’automazione della progettazione elettronica.
Questi strumenti vengono utilizzati per la progettazione di circuiti elettrici, schemi, simulazione, prototipazione e produzione.
Attualmente, il progetto gEDA offre una suite di applicazioni software mature e gratuite per la progettazione elettronica, inclusa la cattura schematica, gestione degli attributi, generazione della distinta base (BOM) , netlisting in oltre 20 formati di netlist, simulazione analogica e digitale e progettazione dei circuiti stampati (PCB ).
Il progetto gEDA è stato avviato per colmare la mancanza di strumenti gratuiti EDA per sistemi POSIX con lo scopo primario di promuovere l’hardware libero o hardware open source.
Lo sviluppo è soprattutto incentrato sulla piattaforma GNU / Linux . Veramente Bello.

UK Version

The gEDA project has produced and continues working on a full GPL'd suite and toolkit of Electronic Design Automation tools. These tools are used for electrical circuit design, schematic capture, simulation, prototyping, and production. Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.
Very Nice

layout keybord raspberry pi

Puo' capitare che usando il conado
#:raspi-config
si cerchi di configurare la tastiera ma questa non viene modificata, in questi casi bisogna:
1)
#:sudo nano /etc/default/keyboard

a questo punto  apparirà questo:

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="gb"
XKBVARIANT=""
XKBOPTIONS=""

BACKSPACE="guess"

 2) cambiare la XKBLAYOUT="gb" in  XKBLAYOUT="it"
3) salvare tutto e ravviare

***** UK**** 
Somatime raspi-config don't work well for change the layoyt the keybord in this situetion you can:

1) #:sudo nano /etc/default/keyboard

 now you can see this

# KEYBOARD CONFIGURATION FILE

# Consult the keyboard(5) manual page.

XKBMODEL="pc105"
XKBLAYOUT="gb"
XKBVARIANT=""
XKBOPTIONS=""

BACKSPACE="guess"

 2) change la XKBLAYOUT="gb" in  XKBLAYOUT="de"

3) save and reboot the raspbarry pi

Esperimenti con la Board Galileo

Primo approccio alla board Galileo

Come prima cosa questo e' il link per il download dei file compressi 

poi (sotto la mia debian 6 con gnome 2.6)

1)
#: tar -zxvf  Intel_Galileo_Arduino_SW_1.5.3_on_Linux64bit_v0.7.5.tgz 

faccio notare che nella guida c'e' un nome sbagliato

2)eliminiamo il modem manager
#:apt-get remove modemmanager

3)

poi entri nella cartella arduino-1.5.3 e lanci

#:./arduino

4)ora passiamo ai dati da mettere nella sd card

per prima cosa bisogna scaricare il file 

LINUX_IMAGE_FOR_SD_Intel_Galileo_v0.7.5.7z 

una volta fatto unzip copiare il suo contenuto nella SD,

inserirla nella scheda e vedere che effetto fà :)

*****UK VERSION******
this is the dowload link

i use debian 6 and gnome 2.6

1)
#: tar -zxvf  Intel_Galileo_Arduino_SW_1.5.3_on_Linux64bit_v0.7.5.tgz
can you see the name of start guide is wrong
2) remove modem manager
#:apt-get remove modemmanager

3) go in arduino folder and write
#: ./arduino

4) download file LINUX_IMAGE_FOR_SD_Intel_Galileo_v0.7.5.7z unzip this file and copy in your SD card

insert SD Card in the board and go on.
