API speed test

By mvuilleu, in Programming, february 27,2012.

The Yoctopuce API provides almost identical functions to drive devices for all supported programming languages, regardless of the huge environment difference between them (take C++ and JavaScript, for example). But are all languages equally good ? Do they all provide the same perfs ? Let's look at this in detail, and expect some surprises...

Reading USB sensors using callbacks

By Sébastien Rinsoz, in Programming, february 14,2012.

Most examples that we provided so far to interact with Yoctopuce USB sensors use sequential function calls. This is called the procedural approach, using polling. We recommend this technique as a starting point, because it is generally more intuitive and less risky. There is, however, an alternative approach, sometimes more convenient: the event-based technique, using callbacks. This is the new API feature that we present today.

New Objective-C library for Mac OS X

By Sébastien Rinsoz, in Programming, january 08,2012.

We have pre-announced the Objective-C library a few weeks ago, it is now available on the programming libraries download page. From now on, you can create Mac OS X Cocoa applications that will natively communicate with Yoctopuce modules (directly using USB, or via TCP).

A Christmas tree driven by Winamp

By martinm, in Programming, december 22,2011.

Let's be honest, last week post about USB Christmas tree was a bit lame. It was fun to blink all these color leds, but that was a lot of Yocto-Color devices to connect for a result very similar to a $10 ornament you would buy from the nearest hardware store. So we decided to improve the concept.

Driving RGB leds using Objective-C

By Sébastien Rinsoz, in Programming, december 18,2011.

This week, we will present something that will be published shortly: the high-level API for Objective-C. The most insightful readers may have already picked up some hints about it. For now, this is only a Mac OS X version, but IOS support will follow after, don't worry.
