1MHz Pulse Width Modulation Controller - repost


This is an embedded controller design, the controller will use a Graphics LCD, digital encoder and 5 push-buttons + USB interface

The encoder will be used to control the PWM duty cycle when the unit is operated manually. the USB will be use to operate the unit remotely from a Laptop PC.

The unit must produce a PWM signal from 100Hz(or less) all the way up to [url removed, login to view] with

0.5% resolution and 5% resolution selected by one of the push-buttons.

A second major feature of this controller will be that it can do frequency Modulation as well with 0.5% and 5% resolutions as well.

A photo of a prototype unit which runs only up to 65Khz is attached, except for the frequency the other difference will be the display.

I would like to discuss the options for implementation of the design.
