Using an I2C infrared camera

By mvuilleu, in Electronics, DIY and Programming, february 10,2023.

There are now small infrared cameras in the form of break-out boards that are very affordable and easy to integrate into automation projects. Surprisingly, they often use the I2C protocol to transfer data. Today, we show you how to use a Yocto-I2C to interface this type of camera.

Creating a Yoctopuce application with PyQt

By mvuilleu, in Programming, january 20,2023.

Python has been among the most widely used programming languages for several years. This is probably due to its remarkable portability between different platforms, including mini-computers such as the Raspberry Pi. It is even possible to use Python to make applications with a real graphical interface, but there are a number of pitfalls, which we will help you avoid...

TLS certificates and the C++ 2.0 library

By seb, in Programming, november 21,2022.

Version 2.0 of the C++ library supports the TLS protocol and allows encrypted communication between the library and the VirtualHub 2.0. This week we have added methods to configure the TLS authentication more precisely, to manage the list of certificates recognized by the library.

Can you reduce the size of the Yoctopuce library?

By mvuilleu, in Programming, november 11,2022.

Customers sometimes ask us if it is possible to use our modules without integrating our programming library. Indeed, at first sight, the library can seem unnecessarily complex when you only want to switch a relay or read a temperature. So the answer is yes... but no. There are ways to reduce the memory footprint of our library, but not to the point of reducing everything to a few manually forged USB packets. Let's look at it in detail.

Experimentation with the Quasar framework

By seb, in Programming, october 28,2022.

Quasar is a framework written in JavaScript that promises the holy grail for developers: to make a cross platform application. Quasar is based on other well-known technologies such as npm, Vue.js, Webpack, Electron, Cordova and gathers them in a single framework. As we are curious, we wanted to test this framework with our TypeScript library.
