You will have to instantiate -devices explicitly. - - -Sysfs attributes ----------------- - -in0_input Voltage at Vcc pin in millivolt (range 2.5V to 5V) -temp1_input Internal chip temperature in millidegrees Celcius - -A subset of the following attributes are visible, depending on the measurement -mode of the chip. - -in[1-4]_input Voltage at V[1-4] pin in millivolt -temp2_input External temperature sensor TR1 in millidegrees Celcius -temp3_input External temperature sensor TR2 in millidegrees Celcius -curr1_input Current in mA across V1-V2 assuming a 1mOhm sense resistor -curr2_input Current in mA across V3-V4 assuming a 1mOhm sense resistor - -The "curr*_input" measurements actually report the voltage drop across the -input pins in microvolts. This is equivalent to the current through a 1mOhm -sense resistor. Divide the reported value by the actual sense resistor value -in mOhm to get the actual value. |
