USBtiny is a software implementation of the USB low-speed protocol for the Atmel ATtiny microcontrollers. Of course, it will also work on the ATmega series. The software is written for an AVR clocked at 12 MHz. At this frequency, each bit on the USB bus takes 8 clock cycles, and with a lot of trickery, it is possible to decode and encode the USB waveforms by software.
Other Atmel AVR Projects he built are
- batwatch – Monitor for a solar panel car battery charger
- webasto – Remote control of Webasto water heater
- blink – Automatic turn signal light
- nikon- Nikon Camera Remote Control
