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
Have you tried Google and Wikipedia?
It is easier if you use a serial-to-onewire converter or a serial port to drive the bus as detailed in:
http://en.wikipedia.org/wiki/1-Wire
Have you followed all the other links there?
For Linux software, OWFS, (but it probably assumes the external converter):
