openharmony 软总线如何测试

恒玄BES2600W SoC 的欧智通的单板基于Openharmony v3.0的底座,其测试的样例代码是基于恒玄公司开发的轻量带屏显示产品样例代码,主要包括图形、软总线等特性产品的开发。

基础介绍:

​ L0的系统基于Liteos-m的m内核,网络使用lwip,其运行的系统为单进程,添加的应用方式采用APP_FEATURE_INIT宏将应用添加进系统中运行。

通过以上示例可以将两台L0的恒玄设备通过分布式软总线进行发布、发现、并组网再发送或接收数据,而且如果将L2设备中软总线关于hichain认证部份进行剥离也可以说不进行认证的情况下,亦可以将一台L0设备与L2设备之间进行发布、发现、组网、数据发送、数据接收。

关于跳过hichain部份在Openharmony的不同版本中处理不同,关于此节会专门做一章节进行描述。
