上次發布了一篇文章（【RTT大賽作品連載】AB32VG1評估板到貨點燈測試-電子發燒友網 (elecfans.com)），解決很多愛好者從在RT-ThreadStudio新建項目到對應開發配置及下載等各部分環節的問題！得到了很多愛好者的認可！

哈哈，先曬點贊的！

重要的是幫好多愛好者解決了實際問題！

接下來看看在如何AB32VG1評估板控制彩燈！

在RT-ThreadStudio新建項目到對應開發配置及下載及驗證測試?。。?/p>

還是詳細點！?。∮媒貓D-》

新建項目！

點完成，新建就好了！

接下來是這次會用的軟件包設置！！！

設置好后點關閉，會提示保存設置選項，點保存即可！

接下來會用到這幾IO！如圖

軟件代碼內容暫時直接寫在main函數文件里！?。?/p>

如圖

具體內容如下：

編譯好，下載驗證如下！

驗證OK！

其實還可以在此基礎上，讓ColorLed'更好玩，喜歡的愛好者可以試試讓它更炫酷?。。?/p>
