By default, LVGL stores all runtime state in a single static
|
|
'lv_global_t' variable, sufficient for most single-display
|
|
single-threaded applications.
|
|
|
|
Enable this if you need multiple independent LVGL instances in
|
|
the same process, for example:
|
|
- Multiple physical displays with separate render loops
|
|
- Per-thread LVGL contexts on an RTOS (FreeRTOS, Zephyr, etc.)
|
|
- Hot-swappable or sandboxed UI instances
|
|
|
|
When enabled, every LVGL internal access to global state goes
|
|
through LV_GLOBAL_CUSTOM() instead of a static variable. You
|
|
must implement 'lv_global_t *lv_global_default(void)' to return
|
|
the correct instance for the current context (e.g. by thread-local
|
|
storage or a guarded pointer switch).
|
|
|
|
Returning NULL from that function is safe; LVGL will treat the
|
|
library as uninitialized for that context.

Disable warning saying `LV_ASSERT_HANDLER_INCLUDE` is deprecated.

This setting allows you to keep using old LVGL versions which rely on
|
|
LV_ASSERT_HANDLER_INCLUDE without triggering a compiler warning.
|
|
|
|
LV_ASSERT_HANDLER_INCLUDE has been deprecated in favor of the new approach:
|
|
define LV_ASSERT_CUSTOM_INCLUDE with the header path, and place the
|
|
LV_ASSERT_HANDLER macro definition inside that header instead.
|
|
|
|
Only enable this if you are maintaining compatibility with existing code
|
|
that uses LV_ASSERT_HANDLER_INCLUDE and cannot migrate immediately.

directly.

Optional header to override LV_ATTRIBUTE_* macros for your platform.

Leave empty to use defaults (all expand to nothing).
|
|
|
|
Create a header file and set this to its path, e.g. "my_lv_attr.h".
|
|
The following macros can be defined in it:
|
|
|
|
LV_ATTRIBUTE_MEM_ALIGN
|
|
Where memory needs to be aligned (e.g. with -Os, data may not be
|
|
aligned to the required boundary by default).
|
|
e.g. __attribute__((aligned(4)))
|
|
|
|
LV_ATTRIBUTE_TICK_INC
|
|
Applied to lv_tick_inc(). Often called from a timer ISR, so fast
|
|
memory placement can reduce latency.
|
|
e.g. __attribute__((section(".itcm"))) or __ramfunc (IAR)
|
|
|
|
LV_ATTRIBUTE_TIMER_HANDLER
|
|
Applied to lv_timer_handler().
|
|
e.g. __attribute__((section(".itcm")))
|
|
|
|
LV_ATTRIBUTE_FLUSH_READY
|
|
Applied to lv_display_flush_ready(). Often called from a DMA or
|
|
display ISR.
|
|
e.g. __attribute__((section(".itcm")))
|
|
|
|
LV_ATTRIBUTE_SYNC_READY
|
|
Applied to lv_display_sync_ready(). Similar to FLUSH_READY, useful
|
|
when called from an ISR context.
|
|
e.g. __attribute__((section(".itcm")))
|
|
|
|
LV_ATTRIBUTE_LARGE_CONST
|
|
Applied to large read-only arrays such as font bitmaps. Use to place
|
|
them in a specific flash region or external memory.
|
|
e.g. __attribute__((section(".ext_flash")))
|
|
|
|
LV_ATTRIBUTE_LARGE_RAM_ARRAY
|
|
Applied to large arrays allocated in RAM.
|
|
e.g. __attribute__((section(".ext_ram")))
|
|
|
|
LV_ATTRIBUTE_FAST_MEM
|
|
Applied to performance-critical functions to place them in faster
|
|
memory such as ITCM or SRAM.
|
|
e.g. __attribute__((section(".itcm"))) or __ramfunc (IAR)
|
|
|
|
LV_ATTRIBUTE_EXTERN_DATA
|
|
Prefix for all global extern data declarations. Useful for placing
|
|
shared data in a named section or applying export attributes.
|
|
e.g. __attribute__((section(".shared_mem")))
|
|
|
|
LV_EXPORT_CONST_INT(int_value)
|
|
Exports an integer constant to a language binding API such as
|
|
MicroPython. Called for all constants in the form LV_<CONST>.
|
|
Leave undefined if not using a binding.
|
|
e.g. mp_rom_map_elem_t entry = {MP_ROM_QSTR(MP_QSTR_##int_value), MP_ROM_INT(int_value)}
