lv_label_set_textYou can set the text on a label at runtime with lv_label_set_text(label, "New text"). This will allocate a buffer dynamically, and the provided string will be copied into that buffer. Therefore, you don't need to keep the text you pass to lv_label_set_text in scope after that function returns.
lv_label_set_text可以在运行时使用 lv_label_set_text(label, "New text") 在标签上设置文本。它将动态分配一个缓冲区，并将提供的字符串复制到该缓冲区中。因此，在该函数返回后，无需将传递给 lv_label_set_text 的文本保留在范围内。Sep 8, 2021 — #define LV_USE_FLOAT 1 does not work for me. In the lv_conf.h file, I’ve also set /* clang-format off */ #if 1 /*Set it to "1" to enable content*/ When I use. lv_label_set_text_fmt(maxOD, "Max. OD: %f", maxODValue); it still gives. Max. OD: f. as output. Any idea what I am missing?
