2 Introduction
2.1 Scope
The STM32JavaF4 ARMCCv4 User Interface Extension is the extension for embedded Java, dedicated
to the STM32JavaF4 ARMCCv4 line of products. As an extension, it requires a platform to run. It
features a complete thread-safe UI software stack, which is highly and easily configurable, and comes
with tools related to User Interface design: font designer, virtual device front panel designer, smart image
rendering, fast font rendering engine, fast 2D drawing, along with low resource consumption and haptic
sensor event management. It targets all major graphical display buffer organizations (zero, one or two
buffers modes, and pixel ordering), is ready for monochrome and full color displays.
This reference manual describes all the functionality of the UI extension. It is concise, but attempts to be
exact and complete. The semantics of the implemented standard libraries are described in their respective specifications. This reference manual only includes specific APIs related to porting UI extension
modules to a hardware device.

5 MicroUI
This user interface extension provides a thread-safe implementation of the [MUI] specification. This
implementation supports displays, inputs (buttons, joysticks, etc.), haptic (touch) sensors and LEDs.
It provides several graphical display buffer modes (double-buffer, direct, custom) as well as several
display memory layouts.

6 Inputs
6.1 Low Level API: LLINPUT
LLINPUT
API is composed of the following files:
• the file LLINPUT_impl.h that defines the functions to be implemented
• the file LLINPUT.h that provides the functions for sending events
6.1.1 Implementation
is the first function called by the input stack and may be used to initialize
the underlying devices and bind them to event generator IDs.
LLINPUT_IMPL_initialize
LLINPUT_IMPL_enterCriticalSection and LLINPUT_IMPL_exitCriticalSection need to provide the
stack with a critical section mechanism for synchronizing devices when sending events to the internal
event queue. The mechanism used to implement the synchronization will depend on the platform configuration (with or without RTOS), and whether or not events are sent from an interrupt context.
allows the input stack to get the current state for devices connected to MicroUI States event generator, such as switch selector, coding wheels, etc.
LLINPUT_IMPL_getInitialStateValue
6.1.2 Sending Events
The LLINPUT API provides two generic functions for a C driver to send data to its associated Java event
generator:
• LLINPUT_sendEvent: sends a 32 bit encoded event to a specific event generator, specified by its ID.
If the input buffer is full the event is not added and the function returns 0, otherwise it returns 1.
• LLINPUT_sendEvents: sends event data to a specific event generator, specified by its ID. If the input
buffer cannot receive the whole data, the event is not added and the function returns 0, otherwise it
returns 1.
Events will be dispatched to the associated Java event generator that will be responsible for decoding
it (see Section 6.2).
The UI extension provides an implementation for each of MicroUI's built-in event generators. Each one
has dedicated functions that allows a driver to send them structured data without needing to understand
the underlying protocol to encode/decode the data. Table 6.1 shows the functions provided to send
structured events to the predefined event generators:

PRESSED), it is the responsibility of the
driver to ensure the integrity of such sequences. Depending on whether a button
of the pointer is pressed while moving, a
DRAG and/or a MOVE MicroUI event is
generated.
LLINPUT_sendPointerMovedEvent
LLINPUT_sendStateEvent
Comments
States
The initial value of each state machine
(of a States) is retrieved by a call to
LLINPUT_IMPL_getInitialStateValue
that needs to be implemented by the device. Alternatively, the initial value can be
specified in the XML static configuration.
LLINPUT_sendTouchPressedEvent
Pointer
LLINPUT_sendTouchReleasedEvent
LLINPUT_sendTouchMovedEvent
In case of chronological sequences (such
as a RELEASE may only occur after a
PRESSED), it is the responsibility of
the driver to ensure the integrity of such
sequences. These APIs will generate a
DRAG MicroUI event instead of a MOVE
while they represent a touch pad over a
display.
a
The implementation class is a subclass of the MicroUI class of the column.
Table 6.1. LLINPUT API for predefined event generators
6.1.3 Event buffer
The maximum usage of the internal event buffer may be retrieved at runtime using
LLINPUT_getMaxEventsBufferUsage function. This is useful for tuning the size of the buffer.
6.2 Java Event Generators
On the Java side, the UI extension provides an abstract class EventGenerator (package
com.is2t.microui.io) that must be implemented by clients who want to define their own event generators. Two abstract methods need to be implemented by subclasses:
• eventReceived: the event generator received an event from a C driver through the low level API
sendEvent function.
• eventsReceived: the event generator received an event made of several ints.
• setProperty: handle a generic property (key/value pair) set from the static initialization file (see
Section 6.3)
The event generator is responsible for converting incoming data to a MicroUI event and sending it to
its listener.
6.3 MicroUI Initialization
The XML file used as input by the MicroUI Static Initialization Tool may contain tags related to the
Input component as described below.

7 Display
7.1 Low Level API: LLDISPLAY
7.1.1 Principle & Naming Convention
Each display stack provides a low level API in order to connect a display driver. The files
LLDISPLAY_[MODE]_impl.h define the API headers to be implemented, where MODE is one of the buffer
modes SWITCH, COPY, DIRECT, CUSTOM. For the APIs themselves, the naming convention is that their
names match the *_IMPL_* pattern when the functions need to be implemented.
7.1.2 Initialization
Each display stack gets initialized the same way:
• first, the function LLDISPLAY_[MODE]_IMPL_initialize is called: it asks its display driver to initialize
itself.
• second, the functions LLDISPLAY_[MODE]_IMPL_getWidth and LLDISPLAY_[MODE]_IMPL_getHeight
are called to retrieve the size of the physical screen.
7.1.3 Display characteristics
Functions LLDISPLAY_[MODE]_IMPL_isColor and LLDISPLAY_[MODE]_IMPL_getNumberOfColors directly implement the methods from the MicroUI Display class of the same names.
7.1.4 Color conversions
LLDISPLAY_[MODE]_IMPL_convertRGBColorToDisplayColor is called to convert a 24 bit RGB MicroUI
color in 0x00RRGGBB format into the "driver" display color.
LLDISPLAY_[MODE]_IMPL_convertDisplayColorToRGBColor is called to convert a display color to a 24
bit RGB MicroUI color.
7.1.5 Contrast
LLDISPLAY_[MODE]_IMPL_setContrast and DISPLAY_[MODE]_IIMPL_getContrast are called to set/get
the current display contrast intensity.
7.1.6 Font alpha adjustment
is called to get the adjustment to apply when
blending font pixels. A positive value makes blended pixels appear lighter, a negative value makes them
appear darker. A value of zero indicates no adjustment.
LLDISPLAY_[MODE]_IMPL_getFontAlphaAdjustment
7.1.7 BackLight
LLDISPLAY_[MODE]_IMPL_hasBackLight
indicates whether the display has backlight capabilities.
and DISPLAY_[MODE]_IIMPL_getBackLight are called to set/
get the current display backlight intensity.
LLDISPLAY_[MODE]_IMPL_setBackLight
LLDISPLAY_DIRECT_IMPL_backlightOn
the backlight
and LLDISPLAY_DIRECT_IMPL_backlightOff enable/disable
7.1.8 Working buffer
The display driver needs to allocate a runtime memory buffer for creating dynamic images when using
MicroUI Image.createImage() methods that explicitly create mutable images.
The display driver may choose to return an empty buffer. Thus, calling MicroUI Image.createImage()
methods will result in a java.lang.OutOfMemoryError exception.

7.1.9 LLDISPLAY_SWITCH
This section describes additional functions to be implemented for the switch buffer mode. The file
LLDISPLAY_SWITCH_impl.h defines the whole set of functions to be implemented.
Function LLDISPLAY_SWITCH_getDisplayBufferAddress returns the address of the display
buffer and LLDISPLAY_SWITCH_getBackBufferAddress returns the address of the back
buffer for the very first drawing. These buffers will be swapped by the function
LLDISPLAY_SWITCH_setDisplayBufferAddress.
LLDISPLAY_SWITCH_synchronize
is called before any new drawing.
7.1.10 LLDISPLAY_COPY
This section describes additional functions to be implemented for the copy buffer mode. The file
LLDISPLAY_COPY_impl.h defines the whole set of functions to be implemented.
returns the back buffer address. The content of this buffer is
copied to the external display memory by the function LLDISPLAY_COPY_copyBuffer. The parameters
define the rectangular area of the content which has changed during the last drawing action and that
must be copied to the display buffer.
LLDISPLAY_COPY_getBackBufferAddress
LLDISPLAY_COPY_synchronize is called before the next drawing after a call to the copy method to avoid
flickering on the display device.
7.1.11 LLDISPLAY_DIRECT
This section describes additional functions to be implemented for the direct buffer mode. The file
LLDISPLAY_DIRECT_impl.h defines the whole set of functions to be implemented.
LLDISPLAY_DIRECT_getDisplayBufferAddress returns the display buffer address which is used simul-
taneously by the stack to draw and the display driver to refresh.
7.1.12 LLDISPLAY_CUSTOM
This section describes additional functions to be implemented for the custom buffer mode. The file
LLDISPLAY_CUSTOM_impl.h defines the whole set of functions to be implemented.
7.1.12.1 Display characteristics
Functions
LLDISPLAY_CUSTOM_getBPP,
LLDISPLAY_CUSTOM_isColor,
LLDISPLAY_CUSTOM_getNumberOfColors and LLDISPLAY_CUSTOM_isDoubleBuffered directly implement the methods from the MicroUI Display class of the same names.
7.1.12.2 Images allocations
Display buffers and images each have a unique ID. LLDISPLAY_CUSTOM_getDisplayBufferIdentifier
returns the integer which uniquely identifies the display.
LLDISPLAY_CUSTOM_allocateImage allocates a buffer for a dynamic image to store
LLDISPLAY_CUSTOM_allocateStaticImageDescriptor only allocates the descriptor
its content, while
for an image that
has been processed by the static images generator. A descriptor is composed of the image width, the
image height and the address of the encoded data content in (read-only) memory. Both functions return
an integer that uniquely identifies the allocated image. LLDISPLAY_CUSTOM_closeImage frees all associated resources to the given image identifier, so that identifier may be reused for future allocations.
7.1.12.3 Drawing primitives
A custom stack has to implement the following basic drawing actions:
17
STM32Java UI Extension: - STM32JavaF4 - Keil uVision [Reference Manual]
• LLDISPLAY_CUSTOM_drawPixel,
• LLDISPLAY_CUSTOM_readPixel
• LLDISPLAY_CUSTOM_copyPixel
• LLDISPLAY_CUSTOM_drawRect
• LLDISPLAY_CUSTOM_fillRect
• LLDISPLAY_CUSTOM_copyArea
7.1.12.4 Synchronization
After the drawing actions, the display stack calls LLDISPLAY_CUSTOM_flush to flush the content of the
back buffer to the display buffer. The parameters define the rectangular area of the content which has
changed during last drawing action and that must be sent to the display buffer.
The display stack calls the method LLDISPLAY_CUSTOM_synchronize to wait for the display device to
refresh before any new drawing may occur.
7.1.12.5 Termination
LLDISPLAY_CUSTOM_dispose

is called at the end of the execution to free all resources associated with
7.2 MicroUI Initialization
The display component augments the static initialization file with:
• the configuration of each display
• fonts that are implicitly embedded within the application (also called system fonts). Applications can
also embed their own fonts.

9.2 Custom Range
Allows the selection of raw Unicode character ranges.
Examples:
• myfont:0x21-0x49: embed all characters from 0x21 to 0x49 (included).
• myfont:0x21-0x49,0x55: embed all characters from 0x21 to 0x49 and character 0x55
• myfont:0x21-0x49;0x55: same as previous, but by declaring two ranges.
9.3 Known Range
A known range is a range available in the following table. Each range is composed of sub-ranges that
have a unique id.
Examples:
• myfont:latin: embed all latin characters
• myfont:latin(5): embed all latin characters of sub range 5 (0xD8 to 0xF6)
• myfont:latin(1-5): embed all latin characters of sub ranges 1 to 5
• myfont:latin(1-5,7): embed all latin characters of sub ranges 1 to 5 and 7
• myfont:latin(1-5);latin(7): same as previous, but by declaring two ranges.
• myfont:latin(1-5);han: embed all latin characters of sub ranges 1 to 5 and all han characters
Table 9.1 describes the available list of ranges and sub-ranges (processed from the "Unicode Character
Database" available on the official unicode website [http://www.unicode.org/]).

10 LEDs
10.1 Low Level API: LLLEDS
10.1.1 Principle
The LEDs stack provides a low level API for connecting LED drivers. The file LLLEDS_impl.h, which
comes with the LEDs stack, defines the API headers to be implemented.
10.1.2 Naming convention
The Low Level API relies on functions that need to be implemented. The naming convention for such
functions is that their names match the *_IMPL_* pattern.
10.1.3 Initialization
The first function called is LLLEDS_IMPL_initialize which allows the driver to initialize all LED devices. This method must return the number of LEDs available.
Each LED has a unique identifier. The first LED has the ID 0 and the last one the ID NbLEDs – 1.
This UI extension provides support to efficiently implement the set of methods that interact with the
LEDs provided by a device. Below are the relevant C functions:
• LLLEDS_IMPL_getIntensity: get the intensity of a specific LED using its ID.
• LLLEDS_IMPL_setIntensity: set the intensity of a LED using its ID.
