Hi I'm using owfs 2.7p5-3 on openwrt kamikaze 7.09 on an asus wl500g deluxe to control my heating system with a python program.
I actually have between 10 to 15 temperature sensors to read and have a performance problem. Some sensors are powered some are not. I'm using 2 hobby board hubs and would like to enable simultaneous temperature reading for at least the one sensors that are powered. owfs is a client of owserver which uses usb. I found no documentation on this. On the web site doc, the simultaneous section exists but is empty. I found a mailing list archive that said: write 1 to /simultaneous/temperature then read the temperature sensors normally. My big problem I had: I don't have the /simultaneous directory when I "ls" in the owfs directory. But when I do 'ls simultaneous', the dir exists! I also found out that there is a simultaneous dir on each "main" and "aux" dirs for the hubs. So I tried to do this (these are powered...) echo 1 > simultaneous/temperature;cat 1F.C4DC03000000/aux/28.C4027E010000/temperature; cat 1F.C4DC03000000/aux/28.0D337E010000/temperature the reading works but it is slow. the first write clears the cache. I tried this echo 1 > simultaneous/temperature;echo 1 > 1F.C4DC03000000/aux/simultaneous/temperature;cat 1F.C4DC03000000/aux/28.C4027E010000/temperature; cat 1F.C4DC03000000/aux/28.0D337E010000/temperature It is quite fast, but the temperature never changes. It is always the cache value that is read, and it is NEVER updated. Can someone tells me what is wrong?
