For some reason my e-mail didn't work anymore, so i couldn't post any messages
to Lugnet. that's why i'm responding so late. So , hoping this time it will
work, I send my post, again(for about the 10th time...)

It looks very good!
You say(on www.lepomux.org) that with other OS-es like NQC,one byte takes 30ms.
Does this mean you actually got a transfer rate from about 30byte/s with NQC?
that would be very cool. I never guessed NQC could work that fast!
Are you releasing some schematics from the LepoMux? i am very intrested in
this (-:

By the way, about my I2C device. I have been very busy, so I didn't got much
time for it. However, I just finished a new schematic for a device which should
make the full 100kHz from the I2C bus possible. Whit an BrickOS-RCX, this
device should make a speed from about 75kHz. SHOULD, I didn't test anything
yet.I hope to got something working soon.

Some days ago we had another idea of how to transfer about 100 bytes/s
without
a kernel patch (that should even work with NQC).

whit NQC? thats intresting! This is even faster than what I got here
whit my BrickOS driver! I would surely like to know more about this! the
I2C device made a max transfer of 27 bits/sec(=about 3,4 bytes/sec(!))
whit NQC.

We'll first check it out before boasting about it ;)
The whole thing won't work without some hardware modifications on the lepomux -
so I'll tell you about it in two or three weeks.

... took slightly longer than 2 weeks, but now it works as expected. Using
BrickOS you'll get up to 100 byte/s without any patch. I've put a protocol
description on www.lepomux.org.
