Customisable In-Car Dashboard Display

This feature of DeltaDash allows custom screens to be created for display of data from the ECU (and any external sensors that may be present). Design and sharing of screen designs may be discussed with other DeltaDash users on the EcuTek forums.

EcuTek In Car Dash

3rd Party Dash Screens

Introduction

This article describes how to create custom in car dashboard screens with DeltaDash. Customisable in car screens are intended to allow use of in car LCD screens such as DVD and SatNav screens. Screen layouts may be fully customised to allow display of virtually any engine (and external sensor) data including analogue, digital and fault code data simultaneously.

This feature is currently under development and so is subject to change, in order to refine the functionality. The creation of custom screens requires thought and effort. Experience will be built up as the user explores the features and options available. If you get into difficulty, visit the EcuTek forums where other users will be able to assist you – support of this feature is via the EcuTek forum only. Well designed screens (with permission from the author) may be incorporated into DeltaDash as some of the standard screens, so get designing !

DeltaDash Version

The earliest DeltaDash version supporting in car dashboard screens is 1.37. Download the latest version from the web site for the most up to date features support.

Designing Custom Screens

DeltaDash allows up to 10 custom dashboard screens to be created, numbered from 0 to 9. When the in car dash screen is selected from the tools menu of DeltaDash, the display will default to screen 0. The user may then switch between screens by using the number keys 0 to 9 or the cursor keys. Hitting 'Enter' reloads the current dashboard screen - this is useful when designing screens.

Each dashboard screen is stored in directory named '0' to '9' within a subdirectory named 'InCarDashScreens' within the DeltaDash directory. E.g. A typical directory for a custom screen would be: 'C:\DeltaDash\InCarDashScreens\0\'. All files relating to a single dash screen must be present in its numbered directory. At a minimum, a custom dashboard screen consists of a single configuration file named 'Form.cfg', though other files may be present, such as bitmaps and sounds.

When DeltaDash is run for the first time on a PC without any custom screens defined, it will generate 10 sample screens that may then more easily be edited by the user.

The Dashboard Configuration File – Form.cfg

This file contains all configuration information for a single custom dashboard screen. In order to create each custom dash screen, a form.cfg file must be edited. The format of the file is described below.

Objects, Classes, Properties and Data Types

The form configuration file defines a number of objects. Each object corresponds to one of the components on the dashboard screen. Each object has a class that defines what 'class' of dashboard component the object is, such as a 'RoundGauge' or an 'LedBarGauge'. Based on this class, the object has a number of properties that may be adjusted to alter the gauge's function and appearance, such as 'Colour', 'NeedleWidth' and 'Font'. Furthermore, each property has a type that defines the type of data that the property holds, such as 'Integer', 'Real Number' and 'String'.

Comments

Comments may be placed in the file by starting the line with a hash '#' character. This character must be the first on the line, with no spaces preceding it.

Objects

The example below shows the structure of an object within the form.cfg file. Each object always begins with the word 'object', followed by the object's name. The name only serves as description to remind the designer what the object is for e.g. CoolantTempGauge. Following the name of the object is a colon ':' followed by the class of the object such as TLedBarGauge. Note that the object class always begins with a capital 'T'. Following this are a number of lines, each setting the value of a single property. Finally, the object ends with the word 'end'.

  object <Name>: T<ObjectClass>
    <AnIntegerProperty>    = <Integer>
    <ARealNumberProperty>  = <Real Number>
    <AStringProperty>      = <String>
    <ABooleanProperty>     = <Boolean>
    <AnOptionListProperty> = <Option>
    …
  end

Classes

Below is the current list of object classes available to the dashboard designer when designing custom screens. Each of these is described in more detail later on.

TDashBackground
TLedBarGauge
TRoundGauge
TSwitchDashGauge
TThresholdGauge
TDashText
TAnalTextGauge
TDashDtcText

Properties

The list of properties that may be set for each object class are detailed later in this document. There are many properties that are common to all classes, such as properties relating to an object's position on the screen (top, left, width & height) and general appearance (color, font & transparent). There are also properties that are specific to certain object classes such as NeedleWidth for a RoundGauge object.

Types

Integer

An integer is a whole number i.e. a number without any digits after the decimal point.

Example:

    Top = 25

An integer can also be specified in hexadecimal notation by preceding the number with a '$' symbol.

Example:

    Top = $19

Real Number

A real number is a number that may contain a fractional component i.e. digits after the decimal point.

Example:

    Density = 0.8

String

A string is a line of text. The string can contain any alphanumeric characters and punctuation but must begin and end with a single quote character.

Example:

    Caption = 'Coolant Temp.'

Boolean

A Boolean property can only have one of two values – True or False.

Example:

    Transparent = True

Option List

An option list property can take one of set list of values. (Programmers may know this as an enumerated type). When each property is explained further on in the document, the list of available options will be listed.

Example:

    DataSource = ddsExternal

Font

A font property has a number of sub properties that define the exact format of text

Example:

    Font.Charset = DEFAULT_CHARSET
    Font.Color = clOlive
    Font.Height = -16
    Font.Name = 'MS Sans Serif'
    Font.Style = [ fsBold, fsItalic,fsUnderline ]

Colour

A colour property is really the same as an integer. A colour is specified as $BBGGRR where RR, GG and BB are the hexadecimal red, green and blue components of the colour. E.g Bright red would be $0000FF, whilst a light grey would be $C0C0C0.

Example:

    Color = $00FF00

General Properties

This is a list of general properties that are available on several components.

Property

Type

Description

Top

Integer

Y co-ordinate of top of component.

Left

Integer

X co-ordinate of left of component

Height

Integer

Height of component in pixels

Width

Integer

Width of component in pixels

Transparent

Boolean

Specifies whether the background can be seen through the component or not. It is slightly slower to draw transparent components than opaque ones, though some interesting effects can be produced with this feature.

Color

Integer

Background colour of the component when it has not been specified as transparent.

Font

Specifies the format of any text displayed by the object.

UpdateInterval

Integer

Specifies how often the value of a gauge is updated. This may be used to prioritise the display of engine parameters. E.g. Retrieve RPM on every request (=1), whilst retrieving vehicle speed and coolant temperature on every other request (=2).

UpdateOffset

Integer

Specifies an offset for data retrieval. E.g. for the above UpdateInterval example, set the offset for RPM and vehicle speed to 0, and the offset for coolant temperature to 1. This would result in requests:

^st

^nd

^rd

MinVal

Real Number

Specifies the minimum value that the control is intended to display.

MaxVal

Real Number

Specifies the maximum value that the control is intended to display.

TextDivide

Real Number

Divides the gauge value before displaying the text. E.g. for an RPM gauge, specifying 1000 would cause the numbers 0 to 8 to be displayed instead of 0 to 8000. This may also be used to convert between units. E.g. Pressures are displayed in PSI by default. To display in bar, set this property to 14.5.

TextOffset

Real Number

Adds to the gauge value before displaying the text. A combination of the TextOffset and TextDivide values may be used to convert from Celcius to Fahrenheit for example.

DataSource

Option List

Specifies whether the data source for the component is the ECU or an external sensor. Options are:

DdsECU – ECU
DdsExternal – External sensor

DataChannelECUAnalogue

Dash Gauge Form

This is the surface on which all dashboard components are placed. Note from the example below that all other components are 'nested' within the DashGaugeForm.

Property	Type	Description
ClientWidth	Integer	The width of the window that will contain the dashboard controls
ClientHeight	Integer	The height of the window that will contain the dashboard controls
Screen	Integer	The screen on which the dashboard will be displayed. This is useful for systems with multiple monitors, such as a laptop with an second dash mounted screen. 0 is the first screen, 1 the second etc etc.

Description

Position

Option List

Specifies how the background should be placed on the screen. Options are:

DbTiled – Image is tiled over entire dash screen.
DbCentred – Image is centred on dash screen

BitmapFile

String

Specifies the name of the bitmap file. This may be in raw bitmap (bmp) format or compressed portable network graphics (png) format. Png is a lossless compression format, so using that file format simply saves disk space.

Example Usage

  object DashBackground: TDashBackground
    Left = 0
    Top = 0
    Width = 640
    Height = 480
    Transparent = False
    Position = dbTiled
    BitmapFile = 'Background.bmp'
  end

LED Bar Gauge

Displays a bar graph component, mimicking a line of LEDs.

Property	Type	Description
SegCount	Integer	Specifies the number of segments (LEDs) in the component.
Density	Real Number	Specifies the density of the bar segments. E.g. a density of 0.8 would specify 80% of the length of the component is used by segments, whilst 20% is used by the space in between each segment.
Rounded	Boolean	Specifies whether the corners of each segment are rounded.
SegmentColoursOn	List of integers	Specifies a list of comma separated colours used when the segments are illuminated.
SegmentColoursOff	List of integers	Specifies a list of comma separated colours used when the segments are not illuminated.
SegmentColourIdxs	List of integers	Specifies the zero based indices of the segments at which the above colours are used. Colours for unspecified segments will be interpolated from the colours for other, adjacent segments colour definitions in the colour lists.
Invert	Boolean	When the width of the component is greater than the height, a horizontal bar graph is drawn. Conversely, when the height is greater then the width, a vertical bar graph is drawn. When 'Invert' is set to true, the bar graph is drawn from right to left (instead of left to right) or top to bottom (instead of bottom to top).
SingleSegment	Boolean	When True, only a single segment is illuminated for the value, rather than a 'bar' of segments up to and including the current value. When SingleSegment is True, both Peak and Trough may be displayed. When false, only the peak value is visible, since the trough will be obscured by the vale bar.

Example Usage

    SegmentColourIdxs = '0,20,28,34,39'
  end

Round Gauge

Displays a highly configurable round gauge, suitable for displaying parameters such as engine RPM, vehicle speed, water temperature etc.

Note that for the round gauge, the values for the MinVal and MaxVal properties may be reversed in order to cause the needle to move anti-clockwise for increasing values. The normal behaviour would be a clockwise movement of the needle for increasing values, though this feature may be useful for gauges which only use a portion of the available 360 degrees available, such as 20 to 160 degrees.

AxleColour	Colour	The colour of the centre circle
NeedleWidth	Integer	The width of the needle or pointer.
NeedleColour	Colour	The colour of the needle
NeedleStart	Integer	The starting radius of the needle.
NeedleEnd	Integer	The ending radius of the needle
TickCount	Integer	The number of major ticks around the gauge. E.g. for an RPM gauge of 0-8000RPM, specify 9 or 17 ticks. Set to 0 for no ticks at all.
TickWidth	Integer	The width of each tick line.
TickColour	Colour	The colour of the tick lines.
TickStart	Integer	The starting radius of the tick lines.
TickEnd	Integer	The ending radius of the tick lines.
SmallTicks	Integer	The number of minor ticks between adjacent major ticks.
TickWidthSmall	Integer	The width of the small tick lines.
TickColourSmall	Integer	The colour of the small tick lines.
TickStartSmall	Integer	The starting radius of the small tick lines.
TickEndSmall	Integer	The ending radius of the small tick lines.
TickTextRadius	Integer	The radius of the tick text from the centre of the gauge.
TextInterval	Integer	The number of ticks between each text tick label. E.g. for a 0-8000 RPM gauge with 17 ticks (500 RPM intervals), specifying an interval of 2 would cause text to be displayed only at 1000 RPM intervals.
TextDPs	Integer	The number of decimal places shown of tick text.
TickFont	Font	The font used to display the tick text.
BandStart	Integer	The starting radius of the colour band.
BandEnd	Integer	The ending radius of the colour band.

  end

Dash DTC Text

Displays any current and historic trouble codes present in a single line of text. If more than one trouble code is present, the component will cycle through all codes present. Note that due to the way in which this component is implemented (so as not to impact on the performance of other gauges) it may take a few seconds before a new trouble code is displayed.

Property	Type	Description
CycleDelay	Integer	Specifies in milliseconds the period for which each trouble code will be displayed before cycling to the next code present.
