Multitouch

caution

This service is experimental and may change in the future.

A capacitive touch sensor with multiple inputs.

import { Multitouch } from "@devicescript/core"

const multitouch = new Multitouch()

Registers​

reading​

Capacitance of channels. The capacitance is continuously calibrated, and a value of 0 indicates no touch, wheres a value of around 100 or more indicates touch. It's best to ignore this (unless debugging), and use events.

Digital sensors will use 0 or 0xffff on each channel.

  • type: Register<any[]> (packing format r: i16)

  • track incoming values

import { Multitouch } from "@devicescript/core"

const multitouch = new Multitouch()
// ...
multitouch.reading.subscribe(async (value) => {
    ...
})
note

write and read will block until a server is bound to the client.

multitouch.touch.subscribe(() => {

multitouch.tap.subscribe(() => {

})

longPress​

Emitted when an input is touched for longer than 500ms. TODO Not implemented.

multitouch.longPress.subscribe(() => {

})

swipePos​

Emitted when input channels are successively touched in order of increasing channel numbers.

multitouch.swipePos.subscribe(() => {

})

swipeNeg​

Emitted when input channels are successively touched in order of decreasing channel numbers.

multitouch.swipeNeg.subscribe(() => {

})
