gexwing / avr_ledstripes

RGB Led Stripe Controller, running on an Atmega.

AVR_LedStripes

Overview

This Project uses an Atmega8 microcontroller to control RGB Led Stripes. The goal of this project is to have a nice modular platform with various modules to control the Color via IR Remote, Sound, or maybe other methods in the future.

src/ - The sourcecode for the Atmege, written in C.
docs/ - documentation for hardware parts and application notes.
eagle/ - CadSoft Eagle Schematics and Board Layout Files.
TLSpice/ - Simulation files to test parts of the board schematics.

Modules

IRMP - Infrared Multiprotocol decoder
SoftPWM - Software Pulse-Width-Modulation with 3 Channels via Timer Interrupt

TODO

[x] Bring code upto date for v2 Board
[] investigate gamma correction for PWM Module
[] Add a microphone with preamp to the board for sound sampling.
[] Add a FFT Module for anazyling sound spectrums.
[] Add Mode for Sounds Controled Lighting
