Introduction Our final project for ECE 4760: Digital Design Using Microcontrollers is a portable keyboard digital synthesizer using the PIC32MX250F128B microcontroller. The PIC creates various sound effects using direct digital synthesis (DDS) and frequency modulation (FM) synthesis which can be modified using user input on our keyboard’s easy-to-use user interface (UI). Our synthesizer is also […]
Introduction For this design project, we built a portable digital synthesizer capable of creating a wide variety of sounds designed by the user. The system consisted of a full octave (13 key) keyboard with two-voice polyphony, three rotary encoders for user input, a TFT LCD for visual display, and an SPI DAC for audio output.
Introduction In this project, I have created a musical synthesizer with the ability to generate realistic instrumental sounds and to record songs for playback with harmonization. Controlled by a PIC32 microcontroller, the synthesizer has over a full octave of buttons, laid out like a piano, to allow playing notes and making chords. It combines additive
DDS (Direct Digital Synthesized) VFO seems to be very popular among amateurs in last few years, mainly thanks to cheap and easy available single-chip DDS synthesizers. There are plenty of different amateur designs, some of them also available in a KIT form. They mostly use Analog Devices AD9850 or AD7008 single-chip DDS system to generate
Parts Used: dsPIC33FJ12GP202 and MCP4921 My day job involves nonindustrial real-time algorithms for machine vision, but in my spare indication I run with a Physicist doing Authority explore that involves the use of low-power micro-controllers.

In EMRFD, 4.10, Wes provides the schema for a versatile VXO – extending frequency synthesizer. Although, I referred him to Wes for help, a reader asked me some questions and I ended up designing some pieces for him. In order to test some of my ideas, I made a VXO – based synthesizer that tuned
For my electrical engineering senior design project, I decided on designing a analog music synthesizer with MIDI control. I have to admit, this was what I wanted to do since high school and was my ultimate goal as a musician, artist, DIY person, and engineer. This project, in the end, will combine all of my
This reference design features the 8T49NS010 integrated circuit that functions as a clock synthesizer with a built-in fanout buffer and divider. By using an external clock source or a crystal, the 8T49NS010 can generate high performance timing geared towards the communications and datacom markets, especially for applications demanding extremely low phase noise jitter, such as
