A library for driving the Freetronics 512 pixel dot matrix LED display "DMD", a 32 x 16 layout using ESP32. This library is a fork of the original one (DMD) modified to support ESP32 (currently it is ...

A team of researchers has discovered how a little-known type of symmetry in quantum materials, called nonsymmorphic symmetry, governs the way these materials interact with intense laser light.

The main objectives in driving multiple LED strings include achieving uniform current control and high-performance pulse width modulation (PWM) dimming for all strings. This study proposes a new ...

A prototype driver is developed for supplying a 144-W-rated LED street-lighting module with utility-line input voltages ranging from 100 to 120 V, and experimental results demonstrate the ...
