Hello Paul (and others),
I'm currently testing my onewire installation with owtcl and an I2C adapter.
It works more or less. I found out there is a nasty bug which is triggered by
OW::finish, but *only* for the DS2482 I2C adapter, not DS9490 or DS9097U,
which I tested, too. So I doubt it's a problem with owtcl, should be inside
owlib.
Please see the attached Tcl script and log. Start with
./ow_finish_bug /dev/i2c-6
or similar to try yourself. /dev/ttyS0 or usb for other adapter work, too, and
don't show the bug.
I used CVS from last week for this test.
Kind regards
Jan
