Intel Galileo: I can’t live without a shell…

New experiments with Intel Galileo from our friend Marco 🙂

Hi ,

as promised in my last post, it’s time to write some code and to create some solded part! 🙂 So…let’s start.

An embedded Linux board without a shell has no sense in my opinion. I think this after many, many, toooooo many experience with embedded boards, so similar to black boxes! 😦

You know, I prefer the old style serial shell (the original RS-232 one!), but since Intel Galileo has a fast ethernet plug one can use also a telnet or ssh connection.

So, if you prefer the RS-232 shell, you must build a simple cable in the following way:

Material:

  • One jack 3.5” stereo male connector (you can reuse it form an old pair of earphones!)
  • One DE-9 pin standard female connector for RS-232
  • Three not too long wires
  • Some basic soldering skill 🙂

Schema (drawn by myself ):

The cable will be connected to the…

Unpacking (and playing with) the Intel Galileo board: first impressions

A new post on Intel Galileo from our friend Marco! 😀

Good morning to all you embedded freaks!

Let’s talk a little about Intel Galileo today. Just a “first impression post”… a very light chunk in order to smoothly introduce the argument.

I opened the box some day ago. In the box there is the board and a power cord with ALL possible plugs (so you can use the Galileo everywhere, but ALWAYS with a power socket on the wall! 🙂 ).

Is it an Arduino Uno or a Linux based embedded board? Mhhh…someone told me it’s a hybrid one between the two things.

But after some very basic experience on this board, I am at the moment very doubtful about the right answer.

In order to do the first (baby) steps with the Galileo board you must use the Quick Start Guide from Intel (you can download it from the official website). It’s a good starting point (since it…

Suggestions on how not to mishandle mathematical formulæ

Quite frequently mathematical formulæ in reports, theses or even articles are not written correctly. Indeed, the basic rules for composing the formulæ are almost never explicitly stated. This article provides some suggestions to fill this gap.
