constructor

new Tmp117(
    bus: I2cBus,
    address: number,
    settings?: Tmp117Settings | null,
): Tmp117
A driver for the part at address on bus. Nothing is sent until init or the first measure.
Parameters
- bus: I2cBus
- address: number
- Optionalsettings: Tmp117Settings | null
Returns Tmp117
- Defined in index.d.ts:3469

Accessors

siliconRevision

get siliconRevision(): number | null
The silicon revision read at initialization, or null before it.

Returns number | null
- Defined in index.d.ts:3491

Methods

alerts

alerts(): Promise<Tmp117Alerts>
Resolves with the alert flags: whether a result since the last call was above the high limit or below the low limit, including results the driver's own reads saw.

Returns Promise<Tmp117Alerts>
- Defined in index.d.ts:3489

init

init(): Promise<void>
Checks the part is a TMP117, waits for its EEPROM to finish loading, and writes the settings with the part in shutdown. Rejects when nothing answers or another part does.

Returns Promise<void>
- Defined in index.d.ts:3474

measure

measure(): Promise<Tmp117Reading>
Runs one conversion and resolves with the temperature, initializing the part first if init has not run.

Returns Promise<Tmp117Reading>
- Defined in index.d.ts:3479

setAlertLimits

setAlertLimits(highCelsius: number, lowCelsius: number): Promise<void>
Writes the high and low limits the part compares each result against; the factory limits are 192 C and -256 C.
Parameters
- highCelsius: number
- lowCelsius: number
Returns Promise<void>
- Defined in index.d.ts:3484
