Hi all,
I think I discovered a problem with caching in the "alarm" directory. See this
transcript:
janskiste:/home/jan # tclsh
% package require ow
0.1
% OW::init /dev/i2c-1
% OW::get
structure/,bus.7/,bus.6/,bus.5/,bus.4/,bus.3/,bus.2/,bus.1/,bus.0/,uncached/,settings/,system/,statistics/,29.5E4101000000/,29.8F4101000000/,1F.071B05000000/,1F.0F1B05000000/,alarm/
% OW::get alarm
--- Put an iButton on the main branch of the DS2409 1F.0F1B05000000, alarm
triggered ---
% OW::get alarm
1F.0F1B05000000/
% OW::put 1F.0F1B05000000/discharge 1
CACHE GET 3 buffer size=4 stored size=4
% OW::get alarm
--- Ok so far. But now again put the iButton on the main branch of the DS2409
1F.0F1B05000000, alarm triggered ---
% OW::get alarm
1F.0F1B05000000/
--- Wait ~1m ---
% OW::get alarm
1F.0F1B05000000/
% OW::put 1F.0F1B05000000/discharge 1
% OW::get alarm
1F.0F1B05000000/
%
--- Huh? Ok, lets check if owfs is caching the alarm or if the chip is still
responding ---
% exit
janskiste:/home/jan # tclsh
% package require ow
0.1
% OW::init /dev/i2c-1
% OW::get alarm
%
Seems to be a problem with caching to me. How do I get rid of the cached
alarm?
Kind regards
Jan
