Hi all,

 

anyone have experience to read a temperature value from a Dallas 1-wire device using for example 1 wire of the coldfire parallel bus ?

I am using uclinux ona a MCF5307. There is a 1-wire driver but don't seems to be able to dialog through a parallel bus wire.

Is there anyone that have developed a bitbanging driver ?

 

 

many thanks

angelo
