I want to connect some DS18B20 temperature sensors to an AVR (ATMega) using the Dallas 1 Wire (which is what these sensors use 
).
I plan to use the DS2484 I2C to One Wire bridge chip to remove the critical one wire timing requirements from the AVR. The DS2484 is a handy chip but it is very low level, so you have to send commands for each 1 wire bit over the I2C.
Has anyone used these chips and therefore written some drivers?
(There seems to be lots of Arduino code around).
