What: /sys/.../iio:deviceX/ac_excitation_en
KernelVersion: 3.1.0
Contact: linux-iio@vger.kernel.org
Description:
This attribute, if available, is used to enable the AC
excitation mode found on some converters. In ac excitation mode,
the polarity of the excitation voltage is reversed on
alternate cycles, to eliminate DC errors.
What: /sys/.../iio:deviceX/bridge_switch_en
KernelVersion: 3.1.0
Contact: linux-iio@vger.kernel.org
Description:
This attribute, if available, is used to close or open the
bridge power down switch found on some converters.
In bridge applications, such as strain gauges and load cells,
the bridge itself consumes the majority of the current in the
system. To minimize the current consumption of the system,
the bridge can be disconnected (when it is not being used
using the bridge_switch_en attribute.
