hdc_std

brief introduction

HDC（OpenHarmony Device Connector） It is a command line tool for developers to debug device connection ,pc The end development machine uses command line tools hdc_std( For convenience , Hereinafter collectively hdc), The tool needs to support deployment in Windows/Linux/Mac Wait for the system to work with OpenHarmony equipment （ Or the simulator ） Connect and debug communication .PC End hdc The tools need to release corresponding versions for the above development machine operating system platforms , Device end hdc daemon It needs to follow the device image release, including support for the simulator . The following will introduce hdc Common commands and use examples .

framework

hdc There are mainly three parts ：

1. hdc client part ： The client running on the development machine , Users can command the terminal in the development machine （windows cmd/linux shell） Request to execute the corresponding hdc command , Run on the development machine , Other terminal debugging IDE Also contains hdc client.
2. hdc server part ： As a background process, it also runs on the development machine ,server management client And device side daemon Communication between includes multiplexing of connections 、 Sending and receiving of data communication packets , And the direct processing of individual local commands .
3. hdc daemon part ：daemon Deployed in OpenHarmony The device side operates as a daemon on demand , Responsible for handling from client End request .
