Open Silicium

Paper 5 now online (in french) on Techno-Innov’s Wiki

The number 15 of Open Silicium is out, so it’ time to publish the paper which was in number 14.

It’s done !

For the curious ones who want to understand what’s behind IDE like Arduino’s IDE, this article is a good start.

You will be led through the required steps to get the usual “Hello World” in it’s micro-controller version: tunring ON a led. Hey, don’t ask for too much, it won’t blink yet.

This paper will be used for the courses during UDOS on Friday morning (July 10, 2015): Discovery of a micro-controller “from scratch”: getting inside, or doing it the other way (from arduino).

New paper in OpenSilicium 14 : Program your GPIO-Demo module from scratch

Open Silicium

As we promised to you, we managed to close the next paper soon enougth to get it in Open Silicium #14 !
It should be available in your favorite book store in a few days (in France). If not, consider fiding a new favorite book store !

Much more than a guide to GPIO Demo module programming, you’ll find a step-by-step how-to which will guide you to the depth of these small black chips you can find in an ever-growing number of everyday-life items.

Don’t wait for them to crush you, get ready for the trip and understand their deepest internals to master them and get the most efficient code for your projects.

Lower prices, new modules, new licence, and wiki launch

This new year brings good news !

First, we lowered most of the prices on our products. Have a look to our store. This is mainly an adaptation to the market prices, hopping it will help us sell more.

We also put our new RF-Sub1GHz modules (868/915MHz) in the store. These are available in three declinations: UEXT for the DomoTab project, USB for development or use from any device which has USB host ports, which opens many other use cases and makes debugging easier, and last but not least, the standalone version, which can be powered from a simple AAA rechargeable battery (or anything above 0.9V, so some simple small photovoltaïc cells may do, to be tested).

For those interrested in the LPC1224 micro-controller but do not care about the UEXT connector or DomoTab modules format, the new LPC1224-BO development board is now on sale. It’s a simplified version of the GPIO Demo module.

Another piece of news which should make many of you happy: some of our products are now under CC-by-sa licence.
This change affects the GPIO Demo module, the brand new RF-Sub1GHz modules, and the LPC1224-BO development board.

We launched (at least !) our wiki, though there’s not much there yet (appart from the previously published papers for Open Silicium, and mainly in french, but we will add content in the upcoming weeks and translate what is already there.

And last, for those interested in the micro-controller software, sources for our modules have been re-organised so that support of new modules and exemples for existing ones is easier (using git branches for each module, easily sharring common code).

Open Silicium – paper 4

Open Silicium

The fourth part of the paper series on the making of of the GPIO Demo module for the DomoTab is published in Open Silicium number 13 !

One year has gone since the previous one (sic) but you now have all the keys to get from design to production with professionnal-like quality while keeping costs very low and with very limited tools.

I give you my word, we will not wait that long for the next one, and programming your micro-controller from scratch will become as easy as your daily programming tasks before summer !

lpctools made it into Debian GNU/Linux

Hi all !

It has been quite a long time since the last piece of news, but we’ve been busy with other projects for our custommers.

Anyway, we keep going on, one step at a time, and the LPC1224 micro-controller support is getting better (it’s the micro-controller we use on the GPIO Demo modules and which will be used on all of our module if possible). Another module is ready, but not it’s documentation, so it will not be on sale till this is fixed, but here is the one piece of news we wanted to share with you today:

lpctools is now included in the Debian GNU/Linux distribution !

In order to get things done we finally asked Freexian services.

Next step : resume the redaction of the papers on the Makin-Of of the GPIO Demo module for Open Silicium. The fourth paper is written (under rereading) and I’m working on the number 5, but it’s growing too fast and will certainly be split in two parts.

Next part of the GPIO Demo Making Of

Open Silicium

The next part of the paper published in Open Silicium number 7 is available in number 8. One could say that’s pure logic, but this time it’s not one, but two papers waiting for your eyes !

The first one (which is the second one in the series) introduces some addons to the schematics, while the second (or third …) moves to the next step and guides you through the steps of the PCB routing process, and of course, using KiCad.

You should not wait to get your hands on it then, or you can keep it at hand as a reference for pcbnew usage, the tool from KiCad suite for the routing process.

Sources for the schematics from Open Silicium n°7 paper

Open Silicium

We wrote a paper for the magazine Open Silicium just published in issue 7 :)

The paper is on page 38 : “Électronique et domotique libre : conception d’un module pour le DomoTab avec Kicad” (Open electronics and home automation: design of a module for DomoTab with KiCad).

Links to the sources for the schematics are in our post A paper in Open Silicium n°7.

The paper is on page 38 : “Électronique et domotique libre : conception d’un module pour le DomoTab avec Kicad” (Open electronics and home automation: design of a module for DomoTab with KiCad).

Do not hesitate to buy the magazine (it should be available on newsstands shortly), or subscribe online :)

Schematics sources from the paper can be downloaded here:

The “RefCard” is available on our wiki. The version covers all written papers, so there’s more than what is in this first paper.

This paper is the first part of the “Making Of” of our GPIO Demo module, and covers the first part of the electronics schematics, but is also a tutorial for KiCad, a very good electronics CAD free software.

We also wrote the next two papers, one on the remaining parts of the schematics, and one on the PCB layout.

More papers will follow : DIY assembly of the module and embedded programming “from scratch” for the micro-controller.

This first set of papers will be followed by papers explaining how to extend the functionnalities of the module, for example to create a weather station, or control a pluged device’s power.
