Firmware update on remote devices

By mvuilleu, in New stuff, december 09,2023.

A year ago, we announced a new tool for monitoring your systems based on Yoctopuce devices via the Internet, called VirtualHub for Web. This tool uses our HTTP callback mechanism to interact with modules, while offering a Web interface very similar to the usual YoctoHub or VirtualHub interface. The first version nevertheless had certain limitations, which we are gradually working to reduce...

New! The Yocto-IO-V2

By martinm, in New stuff, november 10,2023.

This week, we present the Yocto-IO-V2, a digital interface with four fully configurable inputs / outputs. In fact, it does exactly the same thing as the Yocto-IO, a product apparently very popular with Yoctopuce customers. One might well wonder why Yoctopuce decided to develop this version two...

Sending values with communication modules

By mvuilleu, in New stuff, september 15,2023.

Yoctopuce serial communication modules such as Yocto-RS485-V2 and Yocto-I2C are capable of autonomously executing small communication protocols, for example to interrogate sensors. We were recently asked whether it was possible to use a value received from a sensor in a message sent later. As is often the case, the answer is: yes, it's now possible...

Rotary knobs with quadrature encoder

By mvuilleu, in New stuff, august 25,2023.

The Yocto-Knob and Yocto-MaxiDisplay variants have analog inputs for connecting interface buttons: pushbuttons, rotary knobs. However, there was one type of button that was not supported: infinite rotary buttons with quadrature encoder. This limitation has now been lifted.

Taking back control of a YoctoHub-GSM-4G by SMS

By mvuilleu, in New stuff and Misc, august 04,2023.

To take measures in the middle of nowhere and to transmit them to a server, the simplest solution is usually to use a low-power 4G network such as LTE-M or NB-IoT to send them periodically to a server. For example, you could use a YoctoHub-GSM-4G configured to perform HTTP callbacks to a PHP server using VirtualHub for Web. But what if one day the hub stops connecting to the server?
