Hi,
I am having real problems accessing my thermocron ( DS1921G ) without
being root.
/opt/owfs/bin/owfs --foreground --error-level=9 --allow_other -C -u

gives :

maybe you should put another character
why? you filesystem write on latin1 code, your lcd is xyz code, you
should write the lcd xyz asc code, on you latin1 file system
Now I see the codepage

the problem is, how to identify what´s the filesystem charset, after
this everythink is easy
maybe a function on owfs
echo asdfadf message
echo asdfasdf message_latin1
echo asdfasdf message_cb850
or somethink that
Possibly the kernel ds2490 module is grabbing the bus master. What does
dmesg show?

i used lcd on pic18f, putting charset is a very slow feature (for
onewire lan) ok it can run on 1bit/s network but will wait a very big
time
maybe put charset could be easier for microcontrollers on serial port

one think... what charset owfs use? it's does it convert from to any
charset? or it's using ascii table only? (cb850 i think..)

Does setting one user char bitmap takes longer than writing 2x16 chars
on the display?
change one char is less time consuming than 32write chars

Why writing 128 bytes(all 8 user chars) to CG RAM is so time consuming?

Thank you Paul, I will test it ASAP.
Hi Paul,
I have compiled it and I have a problem

Thanks for the report -- sounds like 2 separate problems.

Hello!
I've successfully downloaded from Source Forge a new release. Or so it
had seemed. I go to extract it in my working directory for this
series, and this happens at the end:
gzip: stdin: unexpected end of file
owfs-2.8p6/module/ownet/c/src/include/Makefile.in
check onewire protocol speed
how many bits/second (i think it´s about 16kbits/s)
how many bits to change port bits (i think about 200bits? must check...)
with these numbers you have onewire speed somethink like:
200bits * 16kbit/s = 0,0125 seconds
you can do it, i don´t know, but i think it´s
the numbers must be checked with datasheet it´s just a example...
check onewire speed
check owfs code sent to onewire device
sum the number of bits, multiply by onewire bits/seconds you will get
the minimal speed
check with real application you will get current speed (minimal +
latencies + memory

what this new display/owfs feature should do?
update full rom
update character rom
read full rom
read character rom
for owfs (we use files)
maybe some files:
1)update_display_rom
-send full rom
2)update_display_rom_XXX (XXX start with 1 end with 255)
-send a character bitmap
3)read_display_rom
i think the main problem is: we don´t have this feature in owfs, the
time to write over onewire + time to wait display is just a 'human'
problem, if you want to wait program to execute the charset to be
update you will wait.
do you think that 1 second is a good time to update 80 characters in a

I think there aren't. Mine doesn't have them. Polish language uses latin
alfabet and aditional 8 letters. The codepage iso latin2 is the standard
for few Slavic laguages.
