基于RT1062的lvgl綜合界面-界面配置、驅動代碼

最近確實有點懶，摸了太久的魚，在日天兄的再三催促下，勉勉強強趕上了這個主題月的尾巴。

這次用的板子是騰訊IOT的一塊卡，主控是RT1062，帶一塊800*480的RGB屏。

配界面的時候，使用了GUI-Guider，不得不說，雀食好用，簡單界面拖一拖就能完成，字庫圖庫也是一鍵完成，比官網網頁那個好用多了，就算不用它設計界面，拿來搞個中文小字庫，也是超級方便。

直接拷貝出來的代碼，編譯會報錯，要把guider_fonts.h文件里面 lv_font.h 修改成 lvgl/lvgl.h。

板子的官方沒有把觸摸屏的驅動放出來，這里就把我寫的放下面，有需要的可以看看。
