【STM32F769-discovery开发板】第七篇 Rtthread工程CubeMX生成入门
<p> </p><p ><span style="font-size:16px;"><span style="font-family:宋体;">打开CubeMX，CubeMX本身是不自带RTT组件的，需要自己安装</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">选择管理组件</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">添加新的PACK</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">添加Url，把网上找的Rt-thread链接放进去</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">点check->OK</span></span></p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">开始下载</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">下载速度还是很快的</span></span></p>
<p > </p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">安装完毕</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">在Cube工程里把RTTHREAD</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">三个全都勾选上</span></span></p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">RTTHREAD的默认参数都不改了，都直接默认</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">以前的CubeMx好像取消HardFault_Handler、PendSV_Handler、SysTick_Handler中断函数(RTT已经定义了，需要在CubeMX上取消)</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">现在好像不需要了，我看生成的里面直接写了manage by RTOS</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">除了这个Hard fault好像需要去掉勾</span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"><b>RTTHRAED部分配置好了</b></span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"><b>下面开始配置GPIO部分</b></span></span></p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">不建议HAL库和RTOS使用一个时钟源</span></span></p>
<p > </p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;"> </span></span></p>
<p > </p>
<p > </p>
<p ><span style="font-size:16px;"><span style="font-family:宋体;">设置完成后生成工程</span></span></p>

这是rtthread nano吧，用rtthread studio,不是方便一些？ lugl4313820 发表于 2023-10-23 17:51

<p>是的 应该会更方便</p>
<p>没用过 CUBE比较熟悉就用CUBE了</p>
