Abstraction Layer Interface¶

The following sections briefly describes Abstraction Layer interface changes. For more details, refer to the Migration Guide.

Display¶

UI Pack Range	Changes
[13.0.0-13.3.1]	UI3 format: implement `LLUI_DISPLAY_impl.h`: `void LLUI_DISPLAY_IMPL_initialize([...]);` `void LLUI_DISPLAY_IMPL_binarySemaphoreTake([...]);` `void LLUI_DISPLAY_IMPL_binarySemaphoreGive([...]);` `uint8_t* LLUI_DISPLAY_IMPL_flush([...]);`
[10.0.0-12.1.5]	Remove: `int32_t LLDISPLAY_IMPL_getWorkingBufferStartAddress([...]);` `int32_t LLDISPLAY_IMPL_getWorkingBufferEndAddress([...]);`
[8.0.0-9.4.1]	Merge in `LLDISPLAY_impl.h`: `LLDISPLAY_SWITCH_impl.h` `LLDISPLAY_COPY_impl.h` `LLDISPLAY_DIRECT_impl.h`
[6.0.0-7.4.7]	UI2 format: implement one of header file: `LLDISPLAY_SWITCH_impl.h` `LLDISPLAY_COPY_impl.h` `LLDISPLAY_DIRECT_impl.h`

Input¶

UI Pack Range Changes

[13.0.0-13.3.1]

UI3 format: implement LLUI_INPUT_impl.h:

void LLUI_INPUT_IMPL_initialize([...]);
jint LLUI_INPUT_IMPL_getInitialStateValue([...]);
void LLUI_INPUT_IMPL_enterCriticalSection([...]);
void LLUI_INPUT_IMPL_leaveCriticalSection([...]);

[6.0.0-12.1.5]

UI2 format: implement LLINPUT_impl.h

void LLINPUT_IMPL_initialize([...]);
int32_t LLINPUT_IMPL_getInitialStateValue([...]);
void LLINPUT_IMPL_enterCriticalSection([...]);
void LLINPUT_IMPL_leaveCriticalSection([...]);

LED¶

UI Pack Range Changes

[13.0.0-13.3.1]

UI3 format: implement LLUI_LED_impl.h:

jint LLUI_LED_IMPL_initialize([...]);
jint LLUI_LED_IMPL_getIntensity([...]);
void LLUI_LED_IMPL_setIntensity([...]);

[6.0.0-12.1.5]

UI2 format: implement LLLEDS_impl.h

int32_t LLLEDS_IMPL_initialize([...]);
int32_t LLLEDS_IMPL_getIntensity([...]);
void LLLEDS_IMPL_setIntensity([...]);

Front Panel API¶

Since MicroEJ UI Pack 13.0.0, the Front Panel project must depend on module com.microej.pack.ui.ui-pack(frontpanel). The module version is the MicroEJ Generic UI Pack version, that is always aligned with the MicroEJ UI Packs specific for MCUs.

UI Pack Range	Module	Version
[13.0.0-13.3.1]	`com.microej.pack.ui.ui-pack(frontpanel)`	13.3.1
[12.0.0-12.1.5]	`ej.tool.frontpanel.widget-microui`	1.0.0

Note

Before MicroEJ UI Pack 12.0.0, the Front Panel project must depend on classpath variable FRONTPANEL_WIDGETS_HOME.

Image Generator API¶

Since MicroEJ UI Pack 13.0.0, the Image Generator extension project must depend on module com.microej.pack.ui.ui-pack(imagegenerator). The module version is the MicroEJ Generic UI Pack version, that is always aligned with the MicroEJ UI Packs specific for MCUs.

UI Pack Range	Module	Version
[13.0.0-13.3.1]	`com.microej.pack.ui.ui-pack(imagegenerator)`	13.3.1

Note

Before MicroEJ UI Pack 13.0.0, the Image Generator extension project must depend on classpath variable IMAGE-GENERATOR-x.x.

C Module¶

A C module https://repository.microej.com/modules/com/microej/clibrary/llimpl/microui is available on MicroEJ Central Repository. This C module provides default implementations for:

LLUI_PAINTER_impl.h and LLDW_PAINTER_impl.h: see Low Level API,
Images heap allocator: see Memory,
LLUI_INPUT_IMPL_log_queue_xxx(): see Event Buffer.

The following table describes the compatibility versions between the C modules and the MicroEJ UI Packs:

C Module Range	UI Pack Range
2.0.0	[13.3.0-13.3.1]
[1.1.0-1.1.1]	[13.1.0-13.2.0]
[1.0.0-1.0.3]	[13.0.0-13.1.0]
