HID Events

Overview​

  • All functions in the HID events module require activating HID via the EasyClick HID control host before they can be called
  • For HID control host usage, see Advanced — HID control host: HID control host or use the HID mini host
  • The HID events module uses the hidEvent prefix, e.g. hidEvent.click()
tip
  • EC 10.6.0+ adds USB-mode direct communication functions — useful when the phone and HID control host are not on the same network. Requires HID control host v2.2.0+. See HID USB communication
  • Network mode does not require confirming accessory mode permission on the phone, but devices must be on the same LAN, use a public IP, or use frp forwarding
  • USB mode is not limited by network, but requires manually confirming accessory mode permission
  • USB-mode functions end with ByUsb
  • Both network and USB modes support Advanced networking, which forwards data to slave hosts automatically
  • Choose the mode that fits your scenario
tip
  • HID is one click mode; accessibility, agent, and root modes also provide click and node access. If nodes are unavailable, use image/color matching
  • For image/color capture permission, use image.requestScreenCapture with type=1 (capture with permission)
  • HID cannot use nodes; other features work the same with no special handling
tip
  • HID control host 4.0+ supports the WinUSB driver on Windows — no libusb install required
  • HID control host 4.0 does not support USB communication yet

HID Network Mode Functions​

setHidCenter Set HID Control Host Address​

  • Used in network mode
  • Set the HID control host address
  • Requires EC Android 9.15.0+
  • @param hidCenterUrl URL where the HID control host is running
  • @return {string} null on success; otherwise an error message
function main() {
    let i = initHid()
    if (!i) {
        return
    }
}

function initHid() {
    // First set the LAN address of the HID program; you can also map it to the public network with FRP and use the public address
    hidEvent.setHidCenter("http://192.168.2.14:8988")
    hidEvent.closeUsbDevice();
    sleep(3000)
    let init = hidEvent.initUsbDevice()
    if (init == null) {
        logd("HID device initialized successfully")
    } else {
        loge("Initialization failed:" + init);
        return false
    }
   
    return true;
}

main();

initUsbDevice Initialize HID Device​

  • Used in network mode
  • Initialize the HID device
  • Requires EC Android 9.15.0+
  • @return {string} null on success; otherwise an error message
function main() {
    let i = initHid()
    if (!i) {
        return
    }
}

function initHid() {

}

main();

checkFirstPoint Calibrate HID Coordinates​

  • Used in network mode; deprecated — HID v2.0.0+ does not require coordinate calibration
  • Call after initUsbDevice
  • If the HID control host is v2.0+, do not call this function — click and other actions work without calibration
  • Requires EC Android 9.15.0+
  • @return {string} null on success; otherwise an error message
function main() {
    let i = initHid()
    if (!i) {
        return
    }
}

closeUsbDevice Close HID Device​

multiTouchByUsb Multi-Touch​

  • [USB mode] Multi-touch
  • Requires EC Android 10.6.0+
  • Touch parameters: action — typically 0 = down, 1 = up, 2 = move
  • x: X coordinate
  • y: Y coordinate
  • pointer: finger index — 1, 2, 3, etc.
  • delay: delay before this action in milliseconds; use more than 40 ms to avoid coordinate drift
  • @param touch1 Touch point array for the first finger, e.g.: [{"action":0,"x":1,"y":1,"pointer":1,"delay":30},{"action":2,"x":1,"y":1,"pointer":1,"delay":30}]
  • @param timeout Multi-touch timeout in milliseconds
  • @return {boolean}
