A Dallas One-Wire Library for AVR
This is a little library I wrote with an ATtiny in mind, published to the web in the hopes that others might find it useful.

Features (?)
- It uses a single GPIO pin (no UARTs).
- It does not use dynamic memory allocation. The only drawback is that you have to know the number of devices on the bus in advance (or over-specify).
- It is polled, not interrupt-driven. There are several sections of code that must run for a specific amount of time and have to disable interrupts globally.
- Only the MATCH_ROM, SEARCH_ROM, and SKIP_ROM commands have been implemented. At this point other commands would be trivial to add.
