A quick tutorial on RS485 and MODBUS

By mvuilleu, in Internet of Things and Measures, august 21,2016.

While exchanging with our customers on the best ways to interface industrial controllers, we noticed that nowadays the small secrets enabling you to use an RS485 interface were sometimes unknown from engineers implementing computer or internet based automation. So here is a quick remedial course...

Overview of the UWP library

By seb, in New stuff and Programming, august 10,2016.

Several customers have tried to use our C++ or C# libraries with Windows 10 IoT on a Raspberry Pi. Unfortunately, this doesn't work because Windows 10 IoT is not a "true" Windows: it doesn't allow you to run Win32 applications. You can run only the new universal applications. We are currently working on a solution which would allow you to use our modules on all the Windows 10 versions, including Windows IoT. This post gives us the opportunity to review the matter...

A flying plane counter

Not long ago, someone asked us whether Yoctopuce would be interested in creating an ADS-B receiver. We politely declined because we would likely not sell enough of them to cover the development costs. But we suggested that it should be possible to find an already-made receiver and to interface it with Yoctopuce modules. And this week, we prove it...

How many USB devices can you connect ?

By mvuilleu, in Reviews and Tiny PC, august 01,2016.

The USB specification plans for 127 device adresses on the USB bus, and it is tempting to deduce from this that you can connect up to 127 devices on a USB port. Unfortunately, life is not as simple: this naive reasoning does not take into account all constraints imposed by USB controllers. To give you a better and more useful answer, we have decided to test what works in real life...

Managing the heating of a chalet with a YoctoHub-GSM-2G

By seb, in Internet of Things and DIY, july 21,2016.

A classic example of home automation is to remotely manage the heating system of a second home. In Switzerland, many chalets are equipped with heating systems which are managed by a device connected directly on the phone line. Most of these devices work only on an analog line. If you suppress the phone line or switch it to IP telephony, you must change the device. This week, we are going to see how to replace one of these devices with Yoctopuce modules.
