Chinese Digital PWM modules have come down in cost over the past few months, but picking a PWM module that will help you to do what you need actually means you have to think about a host of things, ...

This Linux loadable kernel module controls multiple PWM channels for driving LEDs using the SDMA on Freescale (NXP) i.MX processors. The module supports pre-loading of 'fades' (a buffer of PWM ...

Hardware PWM by PCA9685. Raspi PCA9685 PWM is built upon Raspi i2c to provide PWM outputs by controlling PCA9685 via I2C connection. It's intended to work on PCA9685 boards such as from Adafruit.

Pulse width modulation (PWM) control, which uses variable-width digital pulses to represent the amplitude of an analog waveform, has been around for decades. The first specialized PWM IC dates back to ...

Abstract: PWM (Pulse Width Modulated) signal generation is known to be the core of power electronic circuits that enable achieve necessary control strategies. The PWM generation modules available on ...

This project demonstrates how a simple and fast pulse width modulator (PWM) generator can be implemented using Verilog programming. It is simulated using ModelSim, a multi-language (hardware ...

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

Abstract: Pulse width modulated (PWM) voltage source converters (VSCs) present unique features such as input-output linearity and control flexibility. However, due to semiconductor devices limitations ...
