Well, power, of course.
We also use some buffering of data. From ow_connection.h

An easy way to test would be to change "16" to "4" in module/owlib/src/c/ow_ds9097U.c lines 837 and 868

I'm currently working with a "Kontron PXA" embedded board, wich seems to have
nostandard serial ports. These ports work fine for serial console, but fail
using the DS2480 based 1W adaptors (with owfs, at least)
Which are the requirements to serial ports - 9600 Baud, I think, but this
works fine with minicom on the other side. Any more requirements (FIFO
support etc.)?
The owserver itself works fine, two 16550 ports of a LPC connected SuperIO
chip work fine with the same board. But I like to use the onboard ports of
the PXA board instead of adding another chip.
By the way - any progress on i2c integration yet?
Kind regards
Jan
