help on OWIN and OWOUT fucntion

I have to make communication with 1 wire, using DS2404 protocol and speed, to communicate with DS2781 fuel gauge IC, communication speed around 16Khz, I use to communicate before using pauseus to do the function, I knew that OWIn and OWOUT could do the transmission protocol, but not much information available , about setting speed, initializing configuration,
I have to use PIC16F690, 8mHz internal oscillator,
could any one help ? thanks

I have not used a one wire device but I will take a shot.

I think the speed is something you do not worry about, it is part of the OWOUT command.
From the data sheet.

TRANSACTION SEQUENCE
The protocol for accessing the DS2781 through the 1-Wire port is as follows:
􀂃 Initialization
􀂃 Net Address Command
􀂃 Function Command
􀂃 Transaction/Data

This makes me think Mode 0 would be used.

Does that sound correct to anyone?

i have tested the function today, and i have checked the timing on the scope, in fact the timg was good, I did set 1 instead of 0 to send a rest first.
I think it woudl work, I have communicate with the slave, I will try it later on.
if you have any information about the initialisation, or more details how OWIN or OWOUT work, I woudl appriciate it,
thanks Mackrackit

I posted all I know :eek:
Like I said, never used it before...

Hook it up and try it out, post the results. Maybe you will get lucky?
