INA226 voltage/current/power monitor

Implementations

impl<I2C, E> INA226<I2C>

where I2C: I2c<Error = E>,

pub fn new(i2c: I2C, address: u8) -> INA226<I2C>

Create a new instance of an INA226 device.

pub fn configuration_raw(&mut self) -> Result<u16, E>

Gets the raw configuration value.

pub fn configuration(&mut self) -> Result<Option<Config>, E>

Gets the configuration.

pub fn set_configuration(&mut self, config: &Config) -> Result<(), E>

Set the configuration of the device.

pub fn shunt_voltage_raw(&mut self) -> Result<i16, E>

Gets the raw shunt voltage measurement.

pub fn shunt_voltage_microvolts(&mut self) -> Result<f64, E>

Gets the shunt voltage in microvolts.

pub fn bus_voltage_raw(&mut self) -> Result<u16, E>

Gets the raw bus voltage measurement.

pub fn bus_voltage_millivolts(&mut self) -> Result<f64, E>

Gets the bus voltage in millivolts.

pub fn power_raw(&mut self) -> Result<u16, E>

Gets the raw calculated power being delivered to the load. Returns zero if callibration has not been performed.

pub fn power_watts(&mut self) -> Result<Option<f64>, E>

Gets the calculated power (in Watts) being delivered to the load. Requires callibration.

pub fn current_raw(&mut self) -> Result<i16, E>

Gets the calculated current flowing through the shunt resistor. Returns zero if callibration has not been performed.

pub fn current_amps(&mut self) -> Result<Option<f64>, E>

Gets the calculated current (in Amps) flowing through the shunt resistor. Requires callibration.

pub fn callibration(&mut self) -> Result<u16, E>

Gets the callibration register, which controls full-scale range of current and power measurements.

pub fn set_callibration_raw(&mut self, value: u16) -> Result<(), E>

Set the callibration register directly. NB: after calling this, only _raw methods can be used.

pub fn callibrate( &mut self, shunt_resistance: f64, current_expected_max: f64, ) -> Result<(), E>

Calibrate the sensitvity of the current and power values.

pub fn mask_enable(&mut self) -> Result<MaskEnableFlags, E>

Get the Alert configuration and Conversion Ready flag.

pub fn set_mask_enable(&mut self, flags: MaskEnableFlags) -> Result<(), E>

Set the Alert configuration and Conversion Ready flags.

pub fn alert_limit(&mut self) -> Result<u16, E>

Get the limit value to compare to the selected Alert function.

pub fn set_alert_limit(&mut self, value: u16) -> Result<(), E>

Set the Alert Limit register.

pub fn manufacturer_id(&mut self) -> Result<u16, E>

Get the unique manufacturer identification number

pub fn die_id(&mut self) -> Result<u16, E>

Get the unique die identification number.

pub fn destroy(self) -> I2C

Destroy the INA226 instance and return the I2C.
