You will have to instantiate -the devices explicitly. - -Example: the following will load the driver for an LTC2945 at address 0x10 -on I2C bus #1: -$ modprobe ltc2945 -$ echo ltc2945 0x10 > /sys/bus/i2c/devices/i2c-1/new_device - - -Sysfs entries -------------- - -Voltage readings provided by this driver are reported as obtained from the ADC -registers. If a set of voltage divider resistors is installed, calculate the -real voltage by multiplying the reported value with (R1+R2)/R2, where R1 is the -value of the divider resistor against the measured voltage and R2 is the value -of the divider resistor against Ground. - -Current reading provided by this driver is reported as obtained from the ADC -Current Sense register. The reported value assumes that a 1 mOhm sense resistor -is installed.
