eCos, un OS peu connu, car dédié à l'embarqué passe en version 3.0.

Vous n'avez probablement jamais entendu parler d'eCos (embedded Configurable operating system). Il s'agit d'un système d'exploitation dédié à l'embarqué dont une des problématiques récurrentes est l'empreinte mémoire restreinte. Ainsi, il est possible d'installer cet OS avec seulement une dizaine de kilo-octets de mémoire. Alors que nous entendons beaucoup parler de Linux, eCos présente l'avantage de pouvoir dans la plupart des cas tenir dans une empreinte mémoire plus petite.

eCos, développé par Red Hat avant d'être donné à la communauté, passe en version 3.0 dont la nouveauté la plus importante est peut-être la compatibilité avec GCC4 ce qui pourrait augmenter sa vitesse de fonctionnement. Le support de la pile TCP/IP a été amélioré et le système de fichiers FAT est désormais de la partie. De nouvelles architectures sont également supportées comme l'ARM Cortex-M et le Fujitsu FR30.

Creation de Micro System "new way of life"

Micro System est un club virtuel soutenu par des étudiants de l'Institut Supérieure d'Electroniques et Communication de Sfax (ISECS- Chaker-Sfax).

Ce club vise à travers ses activités à promouvoir le sens des responsabilité et de la prise de l'initiative chez les étudiants en leur fournissant une formation adéquate qui leur permettra de concrétiser leurs idées de projets.

"This year, we'll start a new business together."

Projet Robotique de l'ESISAR

Le club robotique de l'ESISAR a connecté une Wiimote (télécommande de la console Nintendo Wii) à son robot afin de le contrôler de manière ludique. La transmission passe par un PC et un PDA avant d'atteindre un microcontrôleur PIC dans le robot commandant les moteurs.

La nouvelle manette de Nintendo

La Wiimote parfois appelé "Télécommande Wii" est le nom du contrôleur de la Wii de Nintendo.

Il s'agit d'une manette rectangulaire généralement tenue à une main, mais il est également possible de la tenir à deux mains, comme les manettes conventionnelles, pour certains jeux.


Elle est équipée de plusieurs capteurs lui permettant de se repérer dans l'espace et de retranscrire ses mouvements à l'écran. Cela propose une manière complètement nouvelle et immersive de jouer.

To become a new developer

My idea of departure consists has return you of the professionals in the world of the microcontrôleur
therefore it is the basis to can another day to obtain in the systems embark
for it must get some okay on points of basis
1 the lagunage to which I work with
2 the compiler that I use
3 the operating system
4 the bases of electronics.

First go from it speaks of programming in c
then my compiler it is the high-tech (www.htsoft.com) are himself of the Australian that he conceived it
after goes from it works on Windows and it is obligatory to have some notions on the numeric electronics
like that you can hit yourself the door of embarks it to him and can start some in several project

No Knowledge = No Future

The web is going in a new direction, where people can collaborate generating and cataloguin any kind of information, just associating them to some nice and pretty tags.
Ubiquitous computing is becoming reality, and in the next future computers will be integrated in everyday's life! Two examples are the Wi-Fi technology and the RFID.
RFID are another kind of tags, but not software like the previous. They are hw Radio Frequency devices that can store, send and retrieve data without wires, just using radio frequency communication. RFID will be integrated in everything, creating a literally an "internet of things".
That's all and I want to be ready for the future, and you?

RFID Tags

RFID is an acronym that stands for Radio Frequency Identification, a data acquisition and identification system.
The RFID technology is at a constant improvement, its application ranges from public transport to supermarkets, from banking systems to animal and goods tracking.
Even the world of design is starting to appreciate the huge potential of such a system and its applications within the fields of exhibitions set up, show rooms and the design of new products.

Comparaison between Up and Uc

Let's consider in a first time the minimum system to microprocessor

A memory programs (ROM, PROM, EPROM...).
A memory data (RAM).
An interface input / exits (PIA).
A decoder of address
Different buses of interconnection.
-->A system to microprocessor requires a big material place

The microcontrôleurs permits as for them to free these constraints since they integrate in only one circuit at least all resources clean to a minimum system.

Defintion of the Microcontroler

Now, I think that it is useful to speak a can world that I know
évolution of the domestic products (or industrial) returns account a phenomenon directly bound to in évolution of the technologies
The number of structures built-in to only one component is more and more important.
The number of circuits used is reduced thus.

The solution is then to replace the minimum system by only one circuit: The microcontrôleur.

My First Blog

The idea of the general project seems interesting, I confess that I have the difficulty to understand how to leave to mix all these ideas wholes but good! We are creative us will find a means well all to put without forgetting an idea...
