#define LV_ATTRIBUTE_MEM_ALIGN   __attribute__((aligned(4)))

Added to memories with alignment requirement.

With -Os data might not be aligned to a boundary by default.

#define LV_HOR_RES_MAX   (320)

Maximal horizontal resolution to support by the library.

Definition at line 33 of file lvgl_riot_conf.h.

LV_TICK_CUSTOM

#define LV_TICK_CUSTOM   1

use a custom tick implementation

Definition at line 58 of file lvgl_riot_conf.h.

LV_TICK_CUSTOM_INCLUDE

#define LV_TICK_CUSTOM_INCLUDE   "ztimer.h"

Header for the sys time function.

Definition at line 59 of file lvgl_riot_conf.h.

LV_TICK_CUSTOM_SYS_TIME_EXPR

#define LV_TICK_CUSTOM_SYS_TIME_EXPR   (ztimer_now(ZTIMER_MSEC))

Expression evaluating to current systime in ms.

Definition at line 62 of file lvgl_riot_conf.h.

LV_VER_RES_MAX

#define LV_VER_RES_MAX   (240)

Maximal vertical resolution to support by the library.
