How to build a USB current clamp

By mvuilleu, in Measures, june 10,2022.

A few years ago, we demonstrated how to use a Yocto-milliVolt-Rx to measure DC current, by measuring the very low voltage at the terminals of a shunt resistor. More recently, we thought that it could be useful to extend this scenario to the measure of strong alternative currents using simple ring-shaped current transformers, like current clamps.

Improving ModbusTool

By martinm, in Programming, june 03,2022.

Two weeks ago, we presented an improvement of the Yoctopuce API enabling you to easily observe what happens on a serial line with a callback. Obviously, we hurried to integrate this in our ModbusTool application, which is now able to display the data that go through a Modbus line.

Driving Velux skylight windows with Yoctopuce

By seb, in DIY, may 30,2022.

A few months ago, we wrote a post explaining how to drive the opening of Velux skylight windows with a KLF 200 interface. This week, we are going to improve this system by adding a control panel to it.

Integrating serial snooping into your applications

By mvuilleu, in Programming, may 20,2022.

One of the specificities of Yoctopuce serial interfaces is their capacity to listen to messages circulating on an existing line in both directions to reconstruct the communications. Most of the time, it's used to understand how an undocumented protocol works, but you can also use this function in production to monitor and measure an existing system. That's why we have recently added a new API making it easy to integrate serial snooping into your projects.

A debug tool for Modbus

By martinm, in Misc, may 13,2022.

We have to admit that working with Modbus devices is quite tedious: data are often binary encoded, and all the transactions are validated with a checksum, forcing you to write some code before being able to obtain any result. So, this week, we have a small present for customers using Yoctopuce modules to drive Modbus devices.
