lv_obj_t * label = lv_label_create(obj); lv_label_set_text_fmt(label, "Hello style test %d", lv_pct(100)); } 演示效果如下: 学习点: LV_SIZE_CONTENT在设置这个会议大小的时候,可以用 LVGL 自己选择安排其中内容的大小。 lv_style_set_pad_xxx()可以设置控件内部某方位的边界范围。 lv_pct(...

LVGL需要改动的配置文件叫lv_conf.h 配置需要以下几步: 1、首先进入Arduino IDE的库文件夹,过程和上篇TFT-eSPI的一样 2、找到LVGL的库文件夹,名是小写的lvgl 3、进入,找到名为lv_conf_template.h的文件 4、复制一份,返回上一级文件夹粘贴,是的不是在lvgl这个文件夹内,并改名为lv_conf.h。
