A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

This project demonstrates how to gradually turn an LED on and off using PWM (Pulse Width Modulation) on an STM32 microcontroller. The LED brightness is smoothly increased and decreased by modifying ...

Abstract: 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 ...

Abstract: Light-emitting diode (LED) drivers for automotive lighting applications adopt pulsewidth modulation (PWM) vis-à-vis pulse frequency modulation because its ensuing electromagnetic ...

Digital Multi Meter to measure Hz/Duty Cycle. SEGGER JLink Driver software. If you already knew how to create Synergy Project on E2Studio ignore this screenshot. Here I've combined multiple steps into ...
