Description
Hello, I’m trying to use the PC simulation with a monochrome display to develop my application. I followed this tutorial to install the environment.
Everything worked fine with the default example. The environment is configured correctly.
I change the application and run the below code with default lv_conf.h and lv_drv_conf.h and work fine.
static uint32_t btn_cnt = 1;
static lv_obj_t * main_page;
static lv_obj_t * menu;
static void float_btn_event_cb(lv_event_t * e)
{
LV_UNUSED(e);
btn_cnt++;
lv_obj_t * cont;
lv_obj_t * label;
lv_obj_t * sub_page = lv_menu_page_create(menu, NULL);
cont = lv_menu_cont_create(sub_page);
label = lv_label_create(cont);
lv_label_set_text_fmt(label, "Hello, I am hiding inside %"LV_PRIu32"", btn_cnt);
LV_LOG_USER("LVGL initialization completed!");
cont = lv_menu_cont_create(main_page);
label = lv_label_create(cont);
lv_label_set_text_fmt(label, "Item %"LV_PRIu32"", btn_cnt);
lv_menu_set_load_page_event(menu, cont, sub_page);
lv_obj_scroll_to_view_recursive(cont, LV_ANIM_ON);
}
void lv_example_menu_4(void)
{
/*Create a menu object*/
menu = lv_menu_create(lv_scr_act());
lv_obj_set_size(menu, lv_disp_get_hor_res(NULL), lv_disp_get_ver_res(NULL));
lv_obj_center(menu);
lv_obj_t * cont;
lv_obj_t * label;
/*Create a sub page*/
lv_obj_t * sub_page = lv_menu_page_create(menu, NULL);
cont = lv_menu_cont_create(sub_page);
label = lv_label_create(cont);
lv_label_set_text(label, "Hello, I am hiding inside the first item");
/*Create a main page*/
main_page = lv_menu_page_create(menu, NULL);
cont = lv_menu_cont_create(main_page);
label = lv_label_create(cont);
lv_label_set_text(label, "Item 1");
lv_menu_set_load_page_event(menu, cont, sub_page);
lv_menu_set_page(menu, main_page);
/*Create floating btn*/
lv_obj_t * float_btn = lv_btn_create(lv_scr_act());
lv_obj_set_size(float_btn, 50, 50);
lv_obj_add_flag(float_btn, LV_OBJ_FLAG_FLOATING);
lv_obj_align(float_btn, LV_ALIGN_BOTTOM_RIGHT, -10, -10);
lv_obj_add_event_cb(float_btn, float_btn_event_cb, LV_EVENT_CLICKED, menu);
lv_obj_set_style_radius(float_btn, LV_RADIUS_CIRCLE, 0);
lv_obj_set_style_bg_img_src(float_btn, LV_SYMBOL_PLUS, 0);
lv_obj_set_style_text_font(float_btn, lv_theme_get_font_large(float_btn), 0);
}
But, i need change the application to monochromatic display.
I just change :
LV_COLOR_DEPTH to 1
LV_USE_THEME_DEFAULT to 0
LV_BUILD_EXAMPLES to 0
When the simulation screen opens, just an all white screen with no elements appears. However, when I click where the button should be, its callback is called (I put a log in the console).
Could anyone tell me what I’m doing wrong?
