Wollte nun mal einen DS2450 am PI anschliessen.
\nLeider funktioniert das NICHT mit dem Kernel Modul.
\n(dzt. kein Treiber vorhanden, es taucht nur ein „rw“ device auf…)<\/p>\n
D.h. man muss – leider – den Umweg \u00fcber einen USB-RS232 Converter gehen.<\/p>\n
apt instal owfs<\/p>\n
Server starten :<\/p>\n
owhttpd –passive=\/dev\/ttyUSB0 -p 4444<\/p>\n
Im Browser eingeben, um die Adresse des ds2450 herauszufinden :
\nhttp:\/\/PI_ADRESSE:4444\/bus.0<\/p>\n
Ergebnisse in einem Script verwenden :
\nv=$(wget -qO- http:\/\/127.0.0.1:4444\/uncached\/text\/20.xxxxxxxxxxxx\/volt.ALL | tr ‚,‘ ‚ ‚)<\/p>\n
Test
