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...

Web page, Yocto-Visualization, and actuators (continued)

By martinm, in Programming, september 08,2023.

Three weeks ago, we showed you how to integrate code on a web page that manages Yoctopuce actuators while using Yocto-Visualization (for web). But there was one limitation: we couldn't use the DeviceArrival and DeviceRemoval callbacks because they were already used by Yocto-Visualization (for web), so the code was a bit rickety when it came to checking whether the actuators concerned were connected or not. As this was a bit of a problem for us, we've slightly improved Yocto-Visualization (for web)...

Using TLS/SSL with our PHP library

By seb september 03,2023.

Our PHP library has supported SSL/TLS encryption for several months now. This makes it possible to use the library to connect to VirtualHub v2.0 and VirtualHub for Web. Let's take a look at how to use this feature to establish a secure connection between the library and VirtualHub.

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.

Web page, Yocto-Visualization, and actuators

By martinm, in Programming, august 18,2023.

One of the limitations of Yocto-Visualization is that only sensors are supported. But what if you want to monitor an experiment driven by Yoctopuce actuators and to have the result displayed with Yocto-Visualization without having to run several applications at the same time? Some time ago, we described how to integrate your own web page into Yocto-Visualization (for web). So why not simply create a web page that drives Yoctopuce actuators and then integrate it into Yocto-Visualization (for web). If you know how to code in JavaScript, it looks pretty trivial. Except that it's more subtle than it sounds.
