LED Fader 2

LED Fader 2
LED Fader 2 isย�a projectย�that can control up to 16 outputs, designed for driving LED’s.
All 16 outputs are pulse width modulated, providing 256 levels of brightness at a refresh rate of 100 Hz. A script language, designed for controlling the outputs, is provided as well.
The program is written in AVR assembler for the AT Mega8 and Mega16 microcontrollers from Atmel.[more]

Atmel AVR Infrared Downloader

Atmel AVR Infrared Downloader
This project makes firmware upgrades easy: The target has an Infrared receiver and the data is sent via IR. The IR transmitter is based on AVR-USB.The host-side consist of host-program for Win32 PC using Libusb-Win32, device based on ATmega8 using firmware-only USB driver by Objective Development and infrared hardware unit.Host program was compiled using Lazarus Freepascal. Device firmware was compiled using WinAVR (AVR-GCC).The implementation uses custom device class, required simple inf file and libusb driver on PC.[more]
