开发板设计文档

B91开发板的总体情况可以参见 B91 Generic Starter Kit Hardware Guide 的Overview章节。

详细的开发设计文档可以下载 Reference Design 到本地后,解压后查阅。

环境搭建

推荐在Windows+Ubuntu环境下进行开发,如果对环境搭建的过程有问题,可以参见 环境搭建步骤 中开发环境、安装工具、获取源码、确认目录结构等章节。

编译调试

在完成上述环境搭建之后,可以进行编译生成B91开发板上所需的二进制固件。可以使用烧录工具将固件烧录进B91开发板。 编译调试的详细过程可以参见 编译调试步骤 中编译工程、烧录固件等章节。

示例代码

可以将示例生成的二进制固件烧录进B91开发板,代码默认有3个示例:

  1. LED应用示例

    在B91开发板上烧录固件 led_demo.bin 并上电重启后,可以实现简单的点亮LED灯的功能。 其主要功能的任务代码如下图所示:

    LED应用任务

    第一个任务是使用串口模块打印出 Hello World, time:{RUNNING_TIME_SECOND},另一个是使用开发板上GPIO口去操控蓝色LED灯,实现闪烁效果。 这里的打印间隔以及LED闪烁的间隔都由宏 DELAY 定义,即1000ms。 另外,打印出的时间戳 {RUNNING_TIME_SECOND} 也根据 DELAY 的取值而计时。

  2. BLE测试示例

    在B91开发板上烧录 ble_demo.bin 并上电重启后,可以实现BLE协议栈的相关功能。 通过智能手机上的蓝牙连接工具,如nRF Connect,可以搜索到名为“eSample”的BLE测试示例的广播信息,如下图:

    BLE广播信息

    点击“CONNECT”按钮之后,手机会和B91开发板建立起蓝牙连接,可以在下图中查看到所建立的GATT服务:

    建立连接

    同时,白色的LED灯会在建立连接时进入常亮状态,提示蓝牙已连接。此时按下“DISCONNECT"按钮,蓝牙连接会断开,白灯熄灭。

  3. XTS测试示例

    XTS测试示例是OpenHarmony生态认证测试套件的集合的XTS子系统,在B91开发板上进行的实现。 本实现参考了应用兼容性测试套件中的测试用例源码与配置文件测试用例开发框架

    在B91开发板上烧录 xts_demo.bin 并上电重启后,会运行以下XTS测试用例集合。

        "module_ActsKvStoreTest",
        "module_ActsUtilsFileTest",
        "module_ActsParameterTest",
        "module_ActsBootstrapTest",
        "module_ActsHieventLiteTest",
        "module_ActsDfxFuncTest",
        "module_ActsSamgrTest",

    也可以在 xts_demo\BUILD.gn 当中添加您想要的测试用例集合,测试结果会以串口打印输出。
