Since Visual Basic .NET does not support multiple return values directly, we
use the ByRef
keyword to return multiple values from a function.
All functions and procedures listed below are thread-safe.
BrickletLCD128x64
(ByVal uid As String, ByVal ipcon As IPConnection)¶Creates an object with the unique device ID uid
:
Dim lcd128x64 As New BrickletLCD128x64("YOUR_DEVICE_UID", ipcon)
This object can then be used after the IP Connection is connected.
BrickletLCD128x64.
WritePixels
(ByVal xStart As Byte, ByVal yStart As Byte, ByVal xEnd As Byte, ByVal yEnd As Byte, ByVal pixels() As Boolean)¶Parameters: |
|
---|
Writes pixels to the specified window.
The pixels are written into the window line by line top to bottom and each line is written from left to right.
If automatic draw is enabled (default) the pixels are directly written to the screen. Only pixels that have actually changed are updated on the screen, the rest stays the same.
If automatic draw is disabled the pixels are written to an internal buffer and
the buffer is transferred to the display only after DrawBufferedFrame()
is called. This can be used to avoid flicker when drawing a complex frame in
multiple steps.
Automatic draw can be configured with the SetDisplayConfiguration()
function.
BrickletLCD128x64.
ReadPixels
(ByVal xStart As Byte, ByVal yStart As Byte, ByVal xEnd As Byte, ByVal yEnd As Byte) As Boolean()¶Parameters: |
|
---|---|
Returns: |
|
Reads pixels from the specified window.
The pixels are read from the window line by line top to bottom and each line is read from left to right.
If automatic draw is enabled (default) the pixels that are read are always the same that are shown on the display.
If automatic draw is disabled the pixels are read from the internal buffer
(see DrawBufferedFrame()
).
Automatic draw can be configured with the SetDisplayConfiguration()
function.
BrickletLCD128x64.
ClearDisplay
()¶Clears the complete content of the display.
If automatic draw is enabled (default) the pixels are directly cleared.
If automatic draw is disabled the the internal buffer is cleared and
the buffer is transferred to the display only after DrawBufferedFrame()
is called. This can be used to avoid flicker when drawing a complex frame in
multiple steps.
Automatic draw can be configured with the SetDisplayConfiguration()
function.
BrickletLCD128x64.
WriteLine
(ByVal line As Byte, ByVal position As Byte, ByVal text As String)¶Parameters: |
|
---|
Writes text to a specific line with a specific position.
For example: (1, 10, "Hello") will write Hello in the middle of the second line of the display.
The display uses a special 5x7 pixel charset. You can view the characters of the charset in Brick Viewer.
If automatic draw is enabled (default) the text is directly written to the screen. Only pixels that have actually changed are updated on the screen, the rest stays the same.
If automatic draw is disabled the text is written to an internal buffer and
the buffer is transferred to the display only after DrawBufferedFrame()
is called. This can be used to avoid flicker when drawing a complex frame in
multiple steps.
Automatic draw can be configured with the SetDisplayConfiguration()
function.
This function is a 1:1 replacement for the function with the same name
in the LCD 20x4 Bricklet. You can draw text at a specific pixel position
and with different font sizes with the DrawText()
function.
BrickletLCD128x64.
DrawBufferedFrame
(ByVal forceCompleteRedraw As Boolean)¶Parameters: |
|
---|
Draws the currently buffered frame. Normally each call of WritePixels()
and
WriteLine()
draws directly onto the display. If you turn automatic draw off
(SetDisplayConfiguration()
), the data is written in an internal buffer and
only transferred to the display by calling this function. This can be used to
avoid flicker when drawing a complex frame in multiple steps.
Set the force complete redraw to true to redraw the whole display instead of only the changed parts. Normally it should not be necessary to set this to true. It may only become necessary in case of stuck pixels because of errors.
BrickletLCD128x64.
GetTouchPosition
(ByRef pressure As Integer, ByRef x As Integer, ByRef y As Integer, ByRef age As Long)¶Output Parameters: |
|
---|
Returns the last valid touch position:
BrickletLCD128x64.
GetTouchGesture
(ByRef gesture As Byte, ByRef duration As Long, ByRef pressureMax As Integer, ByRef xStart As Integer, ByRef yStart As Integer, ByRef xEnd As Integer, ByRef yEnd As Integer, ByRef age As Long)¶Output Parameters: |
|
---|
Returns one of four touch gestures that can be automatically detected by the Bricklet.
The gestures are swipes from left to right, right to left, top to bottom and bottom to top.
Additionally to the gestures a vector with a start and end position of the gesture is provided. You can use this vector do determine a more exact location of the gesture (e.g. the swipe from top to bottom was on the left or right part of the screen).
The age parameter corresponds to the age of gesture (how long ago it was).
The following constants are available for this function:
For gesture:

Sets the configuration for up to four graphs.
The graph type can be dot-, line- or bar-graph.
The x and y position are pixel positions.
You can add a text for the x and y axis.
The text is drawn at the inside of the graph and it can overwrite some
of the graph data. If you need the text outside of the graph you can
leave this text here empty and use DrawText()
to draw the caption
outside of the graph.
The data of the graph can be set and updated with SetGUIGraphData()
.
The graph is drawn in a separate GUI buffer and the graph-frame and data will
always stay on top of the graphics drawn with WritePixels()
. To
remove the graph use RemoveGUIGraph()
.

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by assigning a procedure to an callback property of the device object:
Sub MyCallback(ByVal sender As BrickletLCD128x64, ByVal value As Short) Console.WriteLine("Value: {0}", value) End Sub AddHandler lcd128x64.ExampleCallback, AddressOf MyCallback
The available callback property and their type of parameters are described below.
Note
Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

GetResponseExpected
(ByVal functionId As Byte) As Boolean¶Parameters: |
|
---|---|
Returns: |
|
Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.
For getter functions this is enabled by default and cannot be disabled,
because those functions will always send a response. For callback configuration
functions it is enabled by default too, but can be disabled by
SetResponseExpected()
. For setter functions it is disabled by default
and can be enabled.
Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.
The following constants are available for this function:
For functionId:
BrickletLCD128x64.
SetResponseExpected
(ByVal functionId As Byte, ByVal responseExpected As Boolean)¶Parameters: |
|
---|
Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.
Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.
The following constants are available for this function:
For functionId:
BrickletLCD128x64.
SetResponseExpectedAll
(ByVal responseExpected As Boolean)¶Parameters: |
|
---|
