VirtualHub improvements for Linux

By seb, in New stuff, february 26,2021.

Linux is an OS which is widely used in the IoT. Unfortunately for the users discovering this OS, it can be quite confusing. For example, by default, Linux blocks write access to the USB devices for "non-root" users. It isn't really easy to configure an application so that it starts at boot time. This week, we are going to see two small improvements which are going to make the life of Linux users easier.

For our own purposes, we had to make a small do-it-yourself device that would allow us to change on demand the voltage on a USB cable. Given the success that our DIY based on the Ruideng RD6006 power supply gets on a daily basis, we thought that we could also give this opportunity to its little sister, the DPS5005 power supply.

The TypeScript language is a great improvement on JavaScript, as it allows for error detection during compilation rather than during run time. But if it's quite easy to integrate with Node.js, its use to write HTML interfaces without a Node.js server is not so trivial. We are therefore going to show you how to implement an HTML application in TypeScript which optimizes network transfers, so as to install it directly on a YoctoHub-Ethernet.

Many houses were built before the Internet of Things and sometimes we need to convert old, but working, installations in order to monitor them remotely. It's the topic of this week's post. We are going to add a YoctoHub to a Straton furnace in order to receive an alert when the furnace goes out of order.

How to start in TypeScript with Yoctopuce modules

By mvuilleu, in For the beginners and Programming, january 29,2021.

Starting this week, you can use Yoctopuce modules directly from an application written in TypeScript. We have indeed just published a new programming library for this language, which is becoming more and more popular. It's therefore the occasion to offer you a tutorial for new users of Yoctopuce modules, with a short and simple but realistic example. As usual, we assume that you have some prior knowledge of TypeScript programming, but we'll explain the rest in detail.
