Hi,
I've got a few DS2404 chips and I'm playing around with them and an
Arduino. I've got the Arduino connected to the 3-wire port and my laptop
connected via a USB dongle to the 1-wire port. The DS2404 is getting +5V
and ground from the Arduino board. My laptop is running Gentoo with owfs
2.7-p4. For starters I'd like to just write to memory via one port and see
the result via the other. I'm having trouble writing to memory via owfs and
seeing the result also via owfs. I've never played around with a 1-wire
memory device before, only temperature and switch devices, so maybe I'm
doing something wrong. I tried "cat pages/page.0" and get what seems like a
whole lot more than 32 bytes worth of garbage characters. If I then "echo
1234567890 > pages/page.0" and do "cat pages/page.0" again I get the
expected (to me anyway) "1234567890". But then if I cat the same thing
again a minute later it's back to the same garbage characters as before.
I'm guessing that the 1234567890 I see is just cached from the attempted
write.
Also, it looks like the only way to access the memory is a page at a time or
all at once. Is there any way to access a byte at a time, or a range of
bytes other than a whole page?
Has anyone else tried using this device? I know it's been discontinued by
Maxim, but I have a few I'd like to try out in a project.
Thanks,
Ben
