Description
I have trouble setting a string on a label if the string contains more than 13 characters.
Longer strings result in no text at all being rendered , or 1 or 2 random characters are displayed.
What MCU/Processor/Board and compiler are you using?
ESP32-S3-Touch-LCD-4.3
What LVGL version are you using?
8.3.11
What do you want to achieve?
printing a string longer than 13 characters
What have you tried so far?
Decreased the string size by 1 character until the text was correct rendered.
Code to reproduce
code:
String usedSSID = "0123456789abcd";
lv_label_set_text_fmt(ui_LabelSSID,"ssid:\t%s", usedSSID);
The label:
ui_PanelSSID = lv_obj_create(ui_SetupScreen);
lv_obj_set_width(ui_PanelSSID, 548);
lv_obj_set_height(ui_PanelSSID, 43);
lv_obj_set_x(ui_PanelSSID, 78);
lv_obj_set_y(ui_PanelSSID, 111);
lv_obj_set_align(ui_PanelSSID, LV_ALIGN_CENTER);
lv_obj_clear_flag(ui_PanelSSID, LV_OBJ_FLAG_CLICKABLE); /// Flags
lv_obj_set_style_bg_color(ui_PanelSSID, lv_color_hex(0xFFFFFF), LV_PART_MAIN | LV_STATE_DEFAULT);
lv_obj_set_style_bg_opa(ui_PanelSSID, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
lv_obj_set_style_border_width(ui_PanelSSID, 0, LV_PART_MAIN | LV_STATE_DEFAULT);
ui_LabelSSID = lv_label_create(ui_PanelSSID);
lv_obj_set_width(ui_LabelSSID, LV_SIZE_CONTENT); /// 1
lv_obj_set_height(ui_LabelSSID, LV_SIZE_CONTENT); /// 1
lv_obj_set_align(ui_LabelSSID, LV_ALIGN_LEFT_MID);
lv_label_set_text(ui_LabelSSID, "ssid");
lv_obj_set_style_text_color(ui_LabelSSID, lv_color_hex(0xFFFFFF), LV_PART_MAIN | LV_STATE_DEFAULT);
lv_obj_set_style_text_opa(ui_LabelSSID, 255, LV_PART_MAIN | LV_STATE_DEFAULT);
lv_obj_set_style_text_font(ui_LabelSSID, &ui_font_displayRoboto28m, LV_PART_MAIN | LV_STATE_DEFAULT);
