Infrared Camera on the PIC32

Introduction The purpose of this project was to create thermal images displayed on the TFT screen of the PIC32 using data inputted through a thermal camera. A thermal image is an image where the colors are representative of the amount of heat radiated by that location. We used a FLIR Lepton Camera that takes frames […]

PIC32 Digital Synthesizer

PIC32 Digital Synthesizer

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

Programmable IR Station

Introduction The programmable IR remote controller is an IR remote control platform based on PIC32 that can record and resend the Infrared signal. To help users control programmable IR remote controller, an infrared wave server related to database and website is implemented in this project. Bluetooth module creates a bridge between PIC32 and server side

LASER HARP

THE INTERSECTION OF MUSIC WITH TECHNOLOGY CAN CREATE ENTIRELY NEW WAYS TO PRODUCE OR EXPERIMENT WITH MUSIC. THE RECENT HISTORY OF MUSIC HAS TAKEN ADVANTAGE OF THIS TO AUGMENT EXISTING INSTRUMENTS AND MODIFY THEIR SOUND, OR IN THE CASE OF SYNTHESIZERS, TO PRODUCE ENTIRELY NEW AUDIO EFFECTS. OUR PROJECT WAS INSPIRED BY THE NOTION THAT

Distributed PIC Synthesizer

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

ECE 4760: Final Project Report

Introduction For our final project we made a digital vocoder, which could be accomplished over this semester’s remote desktop environment. A vocoder is a synthesizer that generates sounds which are modulated by an input signal. It was originally designed to reduce the bandwidth of voice signals over the telephone, but was never introduced practically. It
