# @ohos.multimodalInput.inputDevice (Input Device) # @ohos.multimodalInput.inputDevice (Input Device)
The **inputDevice** module implements listening for connection, disconnection, and update events of input devices and displays information about input devices. For example, it can be used to listen for mouse insertion and removal and obtain information such as the ID, name, and pointer speed of the mouse.
> **NOTE**<br> The **inputDevice** module allows you to listen for hot swap events of input devices and query information about input devices.
> **NOTE**
>
> The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version. > The initial APIs of this module are supported since API version 8.

# @ohos.ai.mindSporeLite (Inference)
The **mindSporeLite** module provides APIs for the MindSpore Lite inference engine to implment model inference.
MindSpore Lite is an AI engine that implements AI model inference for different hardware devices. It has been used in a wide range of fields, such as image classification, target recognition, facial recognition, and character recognition.
> **NOTE**
>
> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version. Unless otherwise stated, the MindSpore model is used in the sample code.
>
## Modules to Import
```js
import mindSporeLite from '@ohos.ai.mindSporeLite';
```
## Context
Defines the configuration information of the running environment.
### Attributes
**System capability**: SystemCapability.AI.MindSporeLite
| Name | Type | Readable| Writable| Description |
| ------ | ------------------------- | ---- | ---- | ------------------------------------------------------------ |
| target | string[] | Yes | Yes | Target backend. The value can be **cpu** or **nnrt**. The default value is **cpu**. |
| cpu | [CpuDevice](#cpudevice) | Yes | Yes | CPU backend device option. Set this parameter set only when **target** is set to **cpu**. The default value is the combination of the default value of each **CpuDevice** option.|
| nnrt | [NNRTDevice](#nnrtdevice) | Yes | Yes | NNRt backend device option. Set this parameter set only when **target** is set to **nnrt**. Currently, this parameter is empty.|
**Example**
```js
let context: mindSporeLite.Context = {};
context.target = ['cpu','nnrt'];
```
## CpuDevice
Defines the CPU backend device option.
### Attributes
**System capability**: SystemCapability.AI.MindSporeLite
| Name | Type | Readable| Writable| Description |
| ---------------------- | ----------------------------------------- | ---- | ---- | ------------------------------------------------------------ |
| threadNum | number | Yes | Yes | Number of runtime threads. The default value is **2**. |
| threadAffinityMode | [ThreadAffinityMode](#threadaffinitymode) | Yes | Yes | Affinity mode for binding runtime threads to CPU cores. The default value is **mindSporeLite.ThreadAffinityMode.NO_AFFINITIES**.|
| threadAffinityCoreList | number[] | Yes | Yes | List of CPU cores bound to runtime threads. Set this parameter only when **threadAffinityMode** is set. If **threadAffinityMode** is set to **mindSporeLite.ThreadAffinityMode.NO_AFFINITIES**, this parameter is empty. The number in the list indicates the SN of the CPU core. The default value is **[]**.|
| precisionMode | string | Yes | Yes | Whether to enable the Float16 inference mode. The value **preferred_fp16** means to enable half-precision inference and the default value **force_fp32** means to disable half-precision inference. Other settings are not supported.|
**Float16 inference mode**: a mode that uses half-precision inference. Float16 uses 16 bits to represent a number and therefore it is also called half-precision.
**Example**
```js
let context: mindSporeLite.Context = {};
context.cpu = {};
context.target = ['cpu'];
context.cpu.threadAffinityMode = 0;
context.cpu.precisionMode = 'preferred_fp16';

## socket.constructTCPSocketServerInstance<sup>10+</sup>
constructTCPSocketServerInstance(): TCPSocketServer
Creates a **TCPSocketServer** object.
**System capability**: SystemCapability.Communication.NetStack
**Return value**
| Type | Description |
| :---------------------------------- | :---------------------------- |
| [TCPSocketServer](#tcpsocketserver10) | **TCPSocketServer** object.|
**Example**
```js
let tcpServer = socket.constructTCPSocketServerInstance();
```
## TCPSocketServer<sup>10+</sup>
Defines a TCPSocketServer connection. Before invoking TCPSocketServer APIs, you need to call [socket.constructTCPSocketServerInstance](#socketconstructtcpsocketserverinstance10) to create a **TCPSocketServer** object.
### listen<sup>10+</sup>
listen(address: NetAddress, callback: AsyncCallback\<void\>): void
Binds the IP address and port number. The port number can be specified or randomly allocated by the system. The server listens to and accepts TCPSocket connections established over the socket. Multiple threads are used to process client data concurrently. This API uses an asynchronous callback to return the result.
> **NOTE**
> The server uses this API to perform the bind, listen, and accept operations.
**Required permissions**: ohos.permission.INTERNET
**System capability**: SystemCapability.Communication.NetStack
**Parameters**
| Name | Type | Mandatory| Description |
| -------- | ------------------------- | ---- | --------------------------------------------- |
| address | [NetAddress](#netaddress7) | Yes | Destination address.|
| callback | AsyncCallback\<void\> | Yes | Callback used to return the result. |
**Error codes**
| ID| Error Message |
| -------- | ------------------------------------------- |
| 401 | Parameter error. |
| 201 | Permission denied. |
| 2300002 | System internal error. |
| 2303109 | Bad file number. |
| 2303111 | Resource temporarily unavailable try again. |
| 2303198 | Address already in use. |
| 2303199 | Cannot assign requested address. |
**Example**
```js
let tcpServer = socket.constructTCPSocketServerInstance();
tcpServer.listen({ address: "192.168.xx.xxx", port: xxxx, family: 1 }, err => {
if (err) {
console.log("listen fail");
return;
}
console.log("listen success");
})
```
### listen<sup>10+</sup>
listen(address: NetAddress): Promise\<void\>
Binds the IP address and port number. The port number can be specified or randomly allocated by the system. The server listens to and accepts TCPSocket connections established over the socket. Multiple threads are used to process client data concurrently. This API uses a promise to return the result.
> **NOTE**
> The server uses this API to perform the bind, listen, and accept operations.
**Required permissions**: ohos.permission.INTERNET
**System capability**: SystemCapability.Communication.NetStack
**Parameters**
| Name | Type | Mandatory| Description |
| ------- | ------------------------- | ---- | --------------------------------------------- |
| address | [NetAddress](#netaddress7) | Yes | Destination address.|
**Return value**
| Type | Description |
| :-------------- | :----------------------------------------------------------- |
| Promise\<void\> | Promise used to return the result. If the operation is successful, no value is returned. If the operation fails, an error message is returned.|
**Error codes**

| 2303111 | Resource temporarily unavailable try again. |
| 2303198 | Address already in use. |
| 2303199 | Cannot assign requested address. |
**Example**
```js
let tcpServer = socket.constructTCPSocketServerInstance();
let promise = tcpServer.listen({ address: '192.168.xx.xxx', port: xxxx, family: 1 });
promise.then(() => {
console.log('listen success');
}).catch(err => {
console.log('listen fail');
});
```
### getState<sup>10+</sup>
getState(callback: AsyncCallback\<SocketStateBase\>): void
Obtains the status of the TCPSocketServer connection. This API uses an asynchronous callback to return the result.
> **NOTE**
> This API can be called only after **listen** is successfully called.
**Required permissions**: ohos.permission.INTERNET
**System capability**: SystemCapability.Communication.NetStack
**Parameters**
| Name | Type | Mandatory| Description |
| -------- | -------------------------------------------------- | ---- | ---------- |
| callback | AsyncCallback<[SocketStateBase](#socketstatebase7)> | Yes | Callback used to return the result.|
**Error codes**

**Example**
```js
let tcpServer = socket.constructTCPSocketServerInstance();
tcpServer.listen({ address: "192.168.xx.xxx", port: xxxx, family: 1 }, err => {
if (err) {
console.log("listen fail");
return;
}
console.log("listen success");
})
tcpServer.getState((err, data) => {
if (err) {
console.log('getState fail');
return;
}
console.log('getState success:' + JSON.stringify(data));
})
```
### getState<sup>10+</sup>
