A USB full-color scrolling LED display

By mvuilleu, in DIY, july 01,2022.

While working on our radar last week, we realized that it was a bit unfortunate that two Yocto-Color-V2 were required to drive a 32x8 LED display. Even more so, that we had just developped a custom device for a customer, capable of driving 512 RGB LEDs. Therefore, we decided to improve the situation by expanding the capability of the Yocto-Color-V2.

A radar for remote-controlled cars

By martinm june 24,2022.

After Yoctopuce moved into larger premises, it didn't take long for old demons to wake up in some of us. There was a time when, for some members of the team, driving like crazy with remote control cars equipped with cameras was a great way to take a break from work. It's also a very good excuse to test the RFbeam microWave GmbH K-LD7 radar :-)

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.
