Hello all!
 
I've wrotten a driver for 1-wire devices (ROM commands), another for 1 wire
Memory devices (only read and write memory commands) and a OWFS (One Wire
File System) driver.
Those 3 drivers are written with C18, the C compilers of Microchip.
I'm a little tired to work alone on this driver (approx 2000 line of codes
and //comments) and to test it.
That's why i'm looking for people to help me finishing it.
A previous version can be found here:
http://www.novalin.net/C18 (and click on "here", I don't know why there is
this redirection)
you will find an old version of 1-wire driver, with a drv_1wire.h,
drv_1wire.c and drv_1wire.txt
A lot of work has been done since this version. The actual one is not
online, I want to clean  the code and to wrote a .txt wich explain how to
use the memory and OWFS drivers.
 
Actually, here is functions of drv_1wire.c
ReadSlot
WriteSlot
Reset
ReadByte
WriteByte
SearchRom
MatchRom
SkipRom
ReadRom
and another function.
 
here is functions of drv_OWmemory.c
Init
Open device, with "handle" management, in order to make operation on
multiple devices
Close Device
Write Scratchpad
Read Scratchpad
Copy Scratchpad
Read Memory
Write Memory
Verify device (still in writing)
 
here is functions of drv_OWFS.c
Init
Open Device with "handle" management, in order to make operation on multiple
devices
Close Device
Format
Write Page
Read Page
Write file
Read File
OpenFile  with "handle" management, in order to make operation on multiple
files
Close File
Read entry (an entry is a file or a subdirectory)
Search entry (to search a file in a directory, by example)
Copy file (still in writing)
 
have a look at the link above to see the style of writing in this driver,
there is a lot of struct, #define etc... I've "copy" the style of PicOS18
driver to wrote this one, but this not a real time driver, and there is no
queuing in messaging.
 
What i need: people with C18 knowledge, 1-wire memory devices, who have time
to waste to help me finish the actual version (I've already make a lot of
tests)
The next steps will be to wrote drivers for another 1-wire devices
(temperature, battery gauge, security devices)
Another step will be to wrote a PicOS18 version of this driver.
