If you need pure DC wave for other type of application you should design a switching circuit. The circuit diagram is pretty simple; it just has a potentiometer and a Resistor and capacitor to form a ...

The STM32 board is interfaced with an Android phone using Bluetooth. The 8×8 LED matrix connected to Arduino through MAX7219 is controlled through a dedicated application on the Android phone. Fig. 6: ...

The three channels of the LED were controlled by using three timers on the STM32. The timers were set to PWM mode, this allowed for the intensity of each channel to be changed by increasing or ...

WS2812 Driver for STM32 This repository provides a driver for controlling WS2812 LEDs using STM32 microcontrollers. The code is designed for the TIM1 Channel 1 of the STM32L474 MCU but can be adapted ...

Abstract: Recent breakthroughs in solid-state lighting technology has opened the door to a myriad of applications using light-emitting ... system-on-chip driver circuits integrating multiple functions ...

Abstract: This letter reports a novel micro light-emitting diode ($\mu $ LED) pixel driving circuit ... and three capacitors. Hybrid PWM and PAM method is adopted to regulate gray-scales in the ...
