constructor

new Ina219(
    bus: I2cBus,
    address: number,
    settings?: Ina219Settings | null,
): Ina219
A driver for the part at address on bus. Nothing is sent until init or the first measure.
Parameters
- bus: I2cBus
- address: number
- Optionalsettings: Ina219Settings | null
Returns Ina219
- Defined in index.d.ts:1009

Accessors

calibrationWord

get calibrationWord(): number
The calibration word the driver programs.

Returns number
- Defined in index.d.ts:1023

currentLsbMicroamps

get currentLsbMicroamps(): number
The current step the driver programs, in microamps per count.

Returns number
- Defined in index.d.ts:1021

Methods

init

init(): Promise<void>
Resets the part, writes the configuration and the calibration, and reads the calibration back. Rejects when nothing answers or the calibration does not hold.

Returns Promise<void>
- Defined in index.d.ts:1014

measure

measure(): Promise<Ina219Reading>
Triggers one shunt and bus conversion and resolves with every result, initializing the part first if init has not run.

Returns Promise<Ina219Reading>
