<alp/gui.h> — LVGL Re-export

Re-exports the upstream LVGL library with ALP defaults applied so LVGL widgets work out of the box on any E1M target.

Header

#include <alp/gui.h>     // pulls in <lvgl.h> with ALP defaults

board.yaml

libraries:
  - lvgl

The SDK ships a profile header that pre-tunes LVGL for embedded display sizes and 16-bit colour. Override by dropping your own profile at the app's include root.

Minimal LVGL hello-world

#include <alp/gui.h>

lv_obj_t *label = lv_label_create(lv_scr_act());
lv_label_set_text(label, "Hello, E1M!");
lv_obj_align(label, LV_ALIGN_CENTER, 0, 0);

while (1) {
    lv_task_handler();
    k_msleep(5);
}

For the full widget reference, see the LVGL documentation.

ALP widget set (v0.3+)

<alp/gui.h> also ships a small ALP widget set on top of LVGL — cards, status bars, tile layouts — tuned for the kind of dashboards typical of E1M-based products.
