Hello, I have multiple W1-busses based on using DS2482 I2C to W1 interfaces. In W1 file system installed the file "therm_bulk_read" is merely found in the w1_bus_master1 directories, but not in others.
W1 file system is installed either manually via
sudo modprobe ds2482 sudo sh -c "echo ds2482 0x18 > /sys/bus/i2c/devices/i2c-1/new_device" sudo sh -c "echo ds2482 0x1c > /sys/bus/i2c/devices/i2c-1/new_device" sudo modprobe wire
or via rc.local
DS 2482 and DS 2482-8 are used.
As examples directories of master1 and master9 are given.
