Remote device control using WebSocket callbacks

By mvuilleu, in New stuff and Programming, december 26,2015.

Until now, there were two different ways of accessing Yoctopuce devices over the network: either by direct connection over a local network, or using the special HTTP callback mode which makes it possible to drive a Yoctopuce module sitting on a remote network behind a NAT filter. The HTTP callback method however had some limitations. Today, we are introducing a new connection method, named WebSocket callback, that brings all direct connection features to the callback scheme.

Experimenting with EcmaScript 2015

JavaScript comes back from far away. Originally, it was only a source of incompatibilities and a nightmare for web designers. Having to code a version for IE and one for Netscape on the same web site was commonplace. Fortunately, the JavaScript language has evolved amazingly to become the ubiquitous companion of HTML5 on almost all internet sites on the planet. With the latest version of the language, adopted as a new standard this past Summer, new possibilities came into being. They deserve to be known and exploited.

New product: the Yocto-4-20mA-Tx

This week, we present the alter-ego of the Yocto-4-20mA-Rx, that is the Yocto-4-20mA-Tx. This small module enables you to control industrial actuators, as long as they have a 4-20mA input. Let's have a closer look, shall we?

Decoding quadrature signals

The Yocto-PWM-Rx is a sensor with two inputs designed to measure electrical pulse trains. Up to now, we measured the signal on each input for itself, independently from the other input. Now, on top of this, you can analyze the two inputs as a pair of quadrature encoded signals.

The Yocto-GPS

By now, you must have understood it: Yoctopuce R&D department works like a weathercock. The expression is somewhat simplistic, but we do really try to fulfill our customers' expectations. Each time a customer asks us whether we wouldn't want, by any chance, to create a module to do this or that, we carefully write down the request. And we create new products depending on the interest they rouse. This week, it's time for the new GPS module that you have demanded quite often.
