This synchronizes the in-chip conversion rate with the + in-driver readout rate at the cost of an additional register read. + + Writing '1' will remove the polling for the Conversion Ready Flags to + save the additional i2c transaction, which will improve the bandwidth + available for reading data. However, samples can be occasionally skipped + or repeated, depending on the beat between the capture and conversion + rates. + +What: /sys/bus/iio/devices/iio:deviceX/in_shunt_resistor +Date: December 2015 +KernelVersion: 4.4 +Contact: [email protected] +Description: + The value of the shunt resistor may be known only at runtime fom an + eeprom content read by a client application.
