Projeto Final de Curso submetido ao DCC/UFRJ para obtenção do grau de Bacharel em Ciência da Computação.

O dispositivo se identifica como um teclado e um mouse (na verdade, um "absolute pointing device"). A configuração é feita através de um editor de textos qualquer, pois o dispositivo "digita" o menu de configuração.

Há um atraso nos movimentos do ponteiro porque o dispositivo aplica um filtro de suavização.

## English ##

USB HID absolute pointing device using an ATmega8 AVR 8-bit microcontroller and a HMC5883L magnetometer.

Final project in order to obtain Bachelor's degree in Computer Science.

The device identifies itself as a keyboard and a mouse (actually, an "absolute pointing device"). The configuration is done through any simple text editor, as the device "types" the configuration menu.

There is a bit of lag in movements because the device applies a smoothing filter.
