Hello Jan,
First of all, thank you for feedback.
My mistake: I forgot the quote in the $owserver->write command.
More info about my install:
My Perl is the perl-5.14.2 with last CPAN update.
My OWFS is 2.8p15 (RPi default package) , running on Raspbian Raspberry Pi
(last update)
For debugging, strange, when I launch owserver
sudo owserver --debug --nozero --fake=FF.7D0800000100
I obtain
DEBUG MODE
libow version:
2.8p15
If I launch a owdir i.e., I obtain correctly the list with fake 1-wire
node, but no debug info displayed.
Then owserver stops working. So for debugging, this is not easy at all.
I will try to send command to LCD via my sheevaplug instead of RPi tonight
fo a test
Thomas
