Detailed Description

Macro Definition Documentation

#define INA220_BUS_VOLTAGE 0x02

INA220 Bus Voltage register (Read only)

Bus Voltage measurement data

#define INA220_CALIBRATION 0x05

INA220 Calibration register (Read/write)

Sets full-scale range and LSB of current and power measurements. Overall system calibration

#define INA220_CONFIG 0x00

INA220 Configuration register (Read/write)

All-register reset, settings for bus voltage range, PGA gain, ADC resolution/averaging

#define INA220_CURRENT 0x04

INA220 Current register (Read only)

Contains the value of the current flowing through the shunt resistor.

Note: The Current register default to 0 because the Calibration register defaults to 0, yielding a zero current value until the Calibration register is programmed.

#define INA220_POWER 0x03

INA220 Power register (Read only)

Power measurement data

Note: The Power register default to 0 because the Calibration register defaults to 0, yielding a zero current value until the Calibration register is programmed.

#define INA220_SHUNT_VOLTAGE 0x01

INA220 Shunt Voltage register (Read only)

Shunt voltage measurement data
