In ac excitation mode, 7*7e4d7593SAlexandru Tachici the polarity of the excitation voltage is reversed on 8*7e4d7593SAlexandru Tachici alternate cycles, to eliminate DC errors. 9b73b93a2SMircea Caprioru 10b73b93a2SMircea CaprioruWhat: /sys/bus/iio/devices/iio:deviceX/bridge_switch_en 11b73b93a2SMircea CaprioruKernelVersion: 12b73b93a2SMircea CaprioruContact: linux-iio@vger.kernel.org 13b73b93a2SMircea CaprioruDescription: 14*7e4d7593SAlexandru Tachici This attribute, if available, is used to close or open the 15*7e4d7593SAlexandru Tachici bridge power down switch found on some converters. 16*7e4d7593SAlexandru Tachici In bridge applications, such as strain gauges and load cells, 17*7e4d7593SAlexandru Tachici the bridge itself consumes the majority of the current in the 18*7e4d7593SAlexandru Tachici system. To minimize the current consumption of the system, 19*7e4d7593SAlexandru Tachici the bridge can be disconnected (when it is not being used 20*7e4d7593SAlexandru Tachici using the bridge_switch_en attribute. 2142776c14SMircea Caprioru 22*7e4d7593SAlexandru TachiciWhat: /sys/bus/iio/devices/iio:deviceX/in_voltage2-voltage2_shorted_raw 23*7e4d7593SAlexandru TachiciKernelVersion: 24*7e4d7593SAlexandru TachiciContact: linux-iio@vger.kernel.org 25*7e4d7593SAlexandru TachiciDescription: 26*7e4d7593SAlexandru Tachici Measure voltage from AIN2 pin connected to AIN(+) 27*7e4d7593SAlexandru Tachici and AIN(-) shorted. 28
