Front Panel API¶
The Front Panel project must fetch the widgets compatible with the MicroEJ UI Pack fetched in the VEE Port configuration project:
- Before MicroEJ UI Pack
12.0.0
, the Front Panel project must depend on the classpath variableFRONTPANEL_WIDGETS_HOME
. - For the UI Packs
12.x.x
, the Front Panel project must fetch the module ej.tool.frontpanel.widget-microui. - Since MicroEJ UI Pack
13.0.0
, the Front Panel project must depend on the 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 |
---|---|---|
[13.0.0-13.7.0] | com.microej.pack.ui.ui-pack(frontpanel) | [13.0.0-13.7.0] |
[12.0.0-12.1.5] | ej.tool.frontpanel.widget-microui | 1.0.0 |
[6.0.0-11.2.0] | n/a | n/a |
The widget module ej.tool.frontpanel#widget provides some widgets compatible with the Graphics Engine. This module fetches by transitivity the module com.microej.pack.ui.ui-pack(frontpanel). When the Front Panel project does not require/use the latest Front Panel UI API, it can only fetch the widget module.
Note
This module has been moved from the MicroEJ Central Repository to the MicroEJ Developer Repository.
Widget Module Range | UI Pack Compatibility Range | Repository |
---|---|---|
3.0.0 | [13.5.1-10-13.7.0] | Developer |
2.2.0 | [13.1.0-13.7.0] | Developer |
[2.1.0-2.1.1] | [13.1.0-13.7.0] | Central |
2.0.0 | [13.0.0-13.7.0] | Central |
1.0.1 | [12.0.0-12.1.5] | Developer |
To use the latest functionalities provided by the UI Pack 13.0.0
and higher, the Front Panel project must depend on the same version of the UI Pack as the VEE Port configuration project.
However, if the Front Panel project does not require/use the latest Front Panel UI API, it can fetch a version of the UI Pack older than the version fetched in the VEE Port configuration project.
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 |
---|---|---|
[13.0.0-13.7.0] | com.microej.pack.ui.ui-pack(imagegenerator) | [13.0.0-13.7.0] |
Note
Before MicroEJ UI Pack 13.0.0
, the Image Generator extension project must depend on classpath variable IMAGE-GENERATOR-x.x
.
C Modules¶
MicroUI C Module¶
The MicroUI C module com.microej.clibrary.llimpl(microui) is available on MicroEJ Central Repository, see C Modules. The following table describes the compatibility versions between the MicroEJ UI Packs and the C modules:
UI Pack Range | C Module Range | Comment |
---|---|---|
13.7.0 | 3.1.0 | free image resources |
[13.5.0-13.6.2] | 3.0.0 | multiple Graphics Context output formats |
[13.3.0-13.4.1] | [2.0.0-2.0.1] | copy and draw image |
[13.1.0-13.2.0] | [1.1.0-1.1.1] | image heap, events queue, drawing limits |
[13.0.0-13.1.0] | [1.0.0-1.0.3] |
Extended C Modules¶
Some C modules extend the main MicroUI C module. They override the default implementation to use a GPU to perform some drawings. Contrary to the main MicroUI C module, they are optional: when they are not available, the default implementation of drawings is used. The default implementations use the Graphics Engine software algorithms.
STM32 Chrom-ART
The DMA2D C module targets the STM32 CPU that provides the Chrom-ART accelerator.
