Accelerometer
A 3-axis accelerometer.
An accelerometer module should translate acceleration values as follows:
| Orientation | X value (g) | Y value (g) | Z value (g) |
|---|---|---|---|
| Module lying flat | 0 | 0 | -1 |
| Module on left edge | -1 | 0 | 0 |
| Module on bottom edge | 0 | 1 | 0 |
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
Registers
reading
Indicates the current forces acting on accelerometer.
- track incoming values
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
accelerometer.reading.subscribe(async (value) => {
...
})
readingError
Error on the reading value.
- read only
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
const value = await accelerometer.readingError.read()
- track incoming values
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
accelerometer.readingError.subscribe(async (value) => {
...
})
readingRange
Configures the range forces detected. The value will be "rounded up" to one of max_forces_supported.
- read and write
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
// ...
const value = await accelerometer.readingRange.read()
await accelerometer.readingRange.write(value)
- track incoming values
import { Accelerometer } from "@devicescript/core"
const accelerometer = new Accelerometer()
accelerometer.readingRange.subscribe(async (value) => {
...
})
