This feature is implemented through the following modules:
This feature is implemented through the following modules:
- Intelligent Soft Bus
- DSoftBus
Intelligent Soft Bus is a unified base for seamless interconnection among devices. It powers OpenHarmony with distributed communication capabilities to quickly discover and connect devices, and efficiently transmit data.
DSoftBus is a unified base for seamless interconnection among devices. It powers OpenHarmony with distributed communication capabilities to quickly discover and connect devices, and efficiently transmit data.
- Distributed data management
- Distributed data management
DSoftBus manages apps and user data distributed across different devices. Under such management, user data is no longer bound to a single physical device, and service logic is decoupled from storage. As your apps are running across devices, their data is seamlessly transmitted from one device to another, creating a foundation for a user experience that is smooth and consistent.

As your apps are running across devices, their data is seamlessly transmitted from one device to another, creating a foundation for a user experience that is smooth and consistent.
- Distributed Scheduler
The Distributed Scheduler is designed based on technical features such as DSoftBus, distributed data management, and distributed profile. It builds a unified distributed service management mechanism \(including service discovery, synchronization, registration, and invocation\), and supports remote startup, remote invocation, binding/unbinding, and migration of apps across devices. This way, your app can select the most suitable device to perform distributed tasks based on the capabilities, locations, running status, and resource usage of different devices, as well as user habits and intentions.

# Raw File Development
## When to Use
This document describes how to use the native Rawfile APIs to manage raw file directories and files in OpenHarmony. The table below describes the APIs.
## Available APIs
| API | Description |
| :----------------------------------------------------------- | :--------------------------------------- |
| NativeResourceManager *OH_ResourceManager_InitNativeResourceManager(napi_env env, napi_value jsResMgr) | Initializes the native resource manager. |
| RawDir *OH_ResourceManager_OpenRawDir(const NativeResourceManager *mgr, const char *dirName) | Opens a raw file directory. |
| int OH_ResourceManager_GetRawFileCount(RawDir *rawDir) | Obtains the number of raw files in the specified directory.|
| const char *OH_ResourceManager_GetRawFileName(RawDir *rawDir, int index) | Obtains the name of a raw file. |
| RawFile *OH_ResourceManager_OpenRawFile(const NativeResourceManager *mgr, const char *fileName) | Opens a raw file. |
| long OH_ResourceManager_GetRawFileSize(RawFile *rawFile) | Obtains the size of a raw file. |
| int OH_ResourceManager_SeekRawFile(const RawFile *rawFile, long offset, int whence) | Seeks a data read/write position in a raw file based on the specified offset. |
| long OH_ResourceManager_GetRawFileOffset(const RawFile *rawFile) | Obtains the offset. |
| int OH_ResourceManager_ReadRawFile(const RawFile *rawFile, void *buf, size_t length) | Reads a raw file. |
| void OH_ResourceManager_CloseRawFile(RawFile *rawFile) | Closes a raw file to release resources. |
| void OH_ResourceManager_CloseRawDir(RawDir *rawDir) | Closes a raw file directory to release resources. |
| bool OH_ResourceManager_GetRawFileDescriptor(const RawFile *rawFile, RawFileDescriptor &descriptor) | Obtains the file description (FD) of a raw file. |
| bool OH_ResourceManager_ReleaseRawFileDescriptor(const RawFileDescriptor &descriptor) | Releases the FD of a raw file. |
| void OH_ResourceManager_ReleaseNativeResourceManager(NativeResourceManager *resMgr) | Releases native resource manager resources. |
## How to Develop
1. Add the header file.
```c++
#include "raw_file_manager.h"
```
2. Call **OH_ResourceManager_InitNativeResourceManager(napi_env env, napi_value jsResMgr)** to obtain a **NativeResourceManager** instance.
```js
// Call the JS API to pass the JS resource manager.
import resManager from '@ohos.resourceManager'
import rawfileTest from 'librawFileTest.so'
resManager.getResourceManager().then(resmgr => {
rawfileTest.testRawFile("test", resmgr, (error, value) => {
console.log("test rawFile");
})
});
```
```c++
// The C++ API obtains and parses the parameters passed by the JS API.
NativeResourceManager* nativeResourceManager = nullptr;
std::string path;
if (i == 0 && valueType == napi_string) {
// Parse the first parameter, which is the file or directory path relative to the raw file directory.
......
path = buf.data();
} else if (i == 1 && valueType == napi_object) {
// Parse the second parameter, which is the resource manager.
nativeResourceManager = OH_ResourceManager_InitNativeResourceManager(env, argv[i]);
}
```
3. Call **OH_ResourceManager_OpenRawDir** to obtain a **RawDir** instance based on the **NativeResourceManager** instance.
```c++
RawDir* rawDir = OH_ResourceManager_OpenRawDir(nativeResourceManager, path.c_str());
```
4. Call **OH_ResourceManager_GetRawFileCount** to obtain the total number of raw files in the directory based on the **RawDir** instance.
```c++
int count = OH_ResourceManager_GetRawFileCount(rawDir);
```
5. Call **OH_ResourceManager_GetRawFileName** to obtain the name of the raw file based on the specified index.
```c++
for (int index = 0; index < count; index++) {
std::string fileName = OH_ResourceManager_GetRawFileName(rawDir, index);
}
```
6. Call **OH_ResourceManager_OpenRawFile** to obtain a **RawFile** instance based on the specified file name.
```c++
RawFile* rawFile = OH_ResourceManager_OpenRawFile(nativeResourceManager, fileName.c_str());
```
7. Call **OH_ResourceManager_GetRawFileSize** to obtain the size of the raw file.
```c++
long rawFileSize = OH_ResourceManager_GetRawFileSize(rawFile);
```
8. Call **OH_ResourceManager_SeekRawFile** to seek a data read/write position in the raw file based on the specified offset.
```c++
int position = OH_ResourceManager_SeekRawFile(rawFile, 10, 0);
int position = OH_ResourceManager_SeekRawFile(rawFile, 0 , 1);
int position = OH_ResourceManager_SeekRawFile(rawFile, -10, 2);
```
9. Call **OH_ResourceManager_GetRawFileOffset** to obtain the raw file offset.
```c++
long rawFileOffset = OH_ResourceManager_GetRawFileOffset(rawFile)
```
10. Call **OH_ResourceManager_ReadRawFile** to read a raw file.
```c++
std::unique_ptr<char[]> mediaData = std::make_unique<char[]>(rawFileSize);
long rawFileOffset = OH_ResourceManager_ReadRawFile(rawFile, mediaData.get(), rawFileSize);
```
11. Call **OH_ResourceManager_CloseRawFile** to close the file to release resources.
```c++
OH_ResourceManager_CloseRawFile(rawFile);
```
12. Call **OH_ResourceManager_CloseRawDir** to close the raw file directory.
```c++
OH_ResourceManager_CloseRawDir(rawDir);
```
13. Call **OH_ResourceManager_GetRawFileDescriptor** to obtain **RawFileDescriptor** of the raw file.
```c++
RawFileDescriptor descriptor;
bool result = OH_ResourceManager_GetRawFileDescriptor(rawFile, descriptor);
```
14. Call **OH_ResourceManager_ReleaseRawFileDescriptor** to release the FD of the raw file.
```c++
OH_ResourceManager_ReleaseRawFileDescriptor(descriptor);
```
15. Call **OH_ResourceManager_ReleaseNativeResourceManager** to release the native resource manager.
```c++
OH_ResourceManager_ReleaseNativeResourceManager(nativeResourceManager);
```

## DataTransfer<sup>9+</sup>
Use **dataTransfer** to transfer data during the drag operation, so you can perform operations on the data when the drag operation is complete.
### setData<sup>9+</sup>
setData(key: string, value: object): boolean
Sets the data associated with the specified key. If there is no data associated with the key, the data will be appended. If there is already data associated with the key, the data will replace the existing data in the same position.
**Parameters**
| Name | Type | Mandatory | Name |
| ----- | ------ | ---- | ------- |
| key | string | Yes | Data key. |
| value | object | Yes | Data to be stored.|
**Return value**
| Type | Description |
| ------- | ------------------------ |
| boolean | Operation result. The value **true** means that the operation is successful, and **false** means otherwise.|
**Example**
```js
// value in setData can be of a primitive type.
dragStart(e) {
var isSetOk = e.dataTransfer.setData('name', 1);
},
// value in setData can be of the object type.
dragStart(e) {
var person = new Object();
person.name = "tom";
person.age = 21;
var isSetOk = e.dataTransfer.setData('person', person);
}
```
### getData<sup>9+</sup>
getData(key: string): object
Obtains the data associated with the specified key. If no data is associated with the key, an empty string will be returned.
**Parameters**
| Name | Type | Mandatory | Name |
| ---- | ------ | ---- | ----- |
| key | string | Yes | Data key.|
**Return value**
| Type | Description |

dragStart(e) {
var person = new Object();
person.name = "tom";
person.age = 21;
e.dataTransfer.setData('person', person);
},
dragEnd(e){
var person = e.dataTransfer.getData('person');
},
```
### clearData<sup>9+</sup>
clearData(key?: string): boolean
Deletes data associated with the specified key. If there is no data associated with the key, this API will not have any effect.
If the key is null, all data will be deleted.
**Parameters**
| Name | Type | Mandatory | Name |
| ---- | ------ | ---- | ----- |
| key | string | No | Data key.|
**Return value**

# Window Overview
# Window Manager Overview
The Window Manager subsystem provides basic capabilities of window management. It is the basis for UI display.
The Window Manager subsystem enables multiple applications to simultaneously display on the same screen and interact with users. For each application, you need to design the interaction interface in the fixed window area. A window acts as a display container of the application UI, and the Window Manager subsystem organizes the interaction UIs into a form visible to end users.

# MIPI CSI<a name="title_MIPI_CSIDes"></a>
# MIPI CSI
## Overview<a name="section1_MIPI_CSIDes"></a>
## Overview
Defined by the Mobile Industry Processor Interface (MIPI) Alliance, the Camera Serial Interface (CSI) is a specification that allows data to be transmitted from the camera to the host processor on mobile platforms. As the second release, the MIPI CSI-2 consists of the application layer, protocol layer, and physical layer. It supports a maximum of four-lane data transmission and a single-lane transmission rate of 1 Gbit/s.
The physical layer supports the high speed (HS) and low power (LP) modes. Using low-voltage differential signaling (LVDS), the HS mode delivers 80 Mbit/s to 1 Gbit/s transmission speed but high power consumption. The unidirectional LP mode provides lower power consumption but lower transmission speed (< 10 Mbit/s). The blend of the two modes ensures high-speed transmission of massive data (such as images) and minimized power consumption when less data is transmitted.
The physical layer supports the high speed (HS) and low speed (LS) modes. Using low-voltage differential signaling (LVDS), the HS mode delivers 80 Mbit/s to 1 Gbit/s transmission speed but high power consumption. The unidirectional LS mode provides lower power consumption but lower transmission speed (< 10 Mbit/s). The blend of the two modes ensures high-speed transmission of massive data (such as images) and minimized power consumption when less data is transmitted.
The figure below shows a simplified CSI. The D-PHY transmits data by using one pair of source-synchronized differential clocks and one to four pairs of differential data lanes. Data is transmitted in Double Data Rate (DDR) mode, that is, data is transmitted on both the rising and falling edges of the clock.

# OpenHarmony 3.1.1 Release
## Version Description
OpenHarmony 3.1.1 Release provides the following enhancements over OpenHarmony 3.1 Release:
**Enhanced basic capabilities for the standard system**
System service management is enhanced to support group verification. Power management now supports brightness adjustment and battery information query. The Misc services subsystem supports HTTP file download APIs.
The location service subsystem now implements basic positioning APIs. The window manager subsystem supports setting of window properties. The multimedia subsystem provides APIs related to audio focus and audio decoding.
Network management supports Ethernet connections. WebSocket JS APIs are added, which are compatible with the **\@system.fetch** and **\@system.network** APIs.
**Enhanced distributed capabilities for the standard system**
Distributed data management is now compatible with the **\@system.storage** APIs.
**Enhanced application framework capabilities for the standard system**
Bundle management supports application-specific installation status query. The common event and notification subsystem provides APIs for sending and canceling notifications.
The Feature Ability (FA) model supports ability-level screen orientation query and setting, lock screen display, and screen-on during ability startup. DFX features, such as Application Not Response (ANR) and suspension detection for an application's main thread, are added. More basic capabilities are added for FA widgets.
**Enhanced application capabilities for the standard system**
The Contacts application allows third-party applications to invoke the system call capability, so end users can use the basic communication capabilities of devices.
