Introducing the LDS4 Colour Display System
1
The GEMS LDS4 intelligent AMOLED colour display system comprises the LDS4 colour display
and LDS4 Editor editing software. Screen pages are designed graphically and as LDS4 Editor is a
WYSIWYG editor, the screen layout displayed in LDS4 Editor is identical to the layout displayed
on the LDS4.
In addition to the graphical display editor, LDS4 Editor also provides a comprehensive setup
editor to program the input, output and mathematical functionality of the LDS4.
Once created, setups are uploaded to the LDS4 via a USB link.
1.1 Notation used in this manual
Menu commands are signified in bold type with a pipe symbol |between each level of the menu.
For example, File | Open indicates that you should click on the Open option in the File menu.
Italic text is used to indicate text that should be typed in by the user.
1.2 Installing LDS4 Colour Display System
LDS4 Editor is distributed on CD ROM. To install:
·Insert the disk in the CD drive.
·The installation wizard should start automatically. If it does not:
·Click on the Windows Start menu and select Run...
·In the Open box type X:\LDS4 EditorSETUP.EXE (where X is the drive letter of your CD
drive) and click OK.
·The installation wizard starts. Follow the instructions on screen to install the software.
1.2.1 Installing USB Drivers
The installation program will automatically install the USB drivers required by LDS4. However, on
rare occasions, it may be necessary to install the USB drivers manually. To do this:
·Connect the LDS4 to the PC.
·When the add new hardware wizard appears, select "Install from a list or specific location" and
click Next.
·Choose "Search for the best driver in these locations" and check "Include this location in the
search"
·Click the Browse button and navigate to the Drivers folder on the LDS4 Editor CD.
·Click the Next button and the driver installation will proceed automatically.

Revision History
2
2.1 LDS4 Revision History
LDS4 firmware is organised into release families. Generally, setups are compatible with different
versions in a release family; the major changes made between releases may create some
incompatibility with previous versions; this is noted under compatibility issues.
2.1.1 Release 06 Revision History
Known compatibility issues
·Requires version 3.39 or later of editing software.
·Requires v2.06 or later of Emerald.dll.
06x00 - 27/11/09 - Changes from Release 05
·Added CAN status messages.
·Optimised interface to RTC. This optimisation has freed up processor time and makes the
display operation appear smoother.
·Fixed bug in square bar graph when in "draw from centre" mode which could leave bars
unerased.
·Numeric value gauge supports a warning colour and warning value which makes the gauge
change colour when the value is exceeded.
·Added day, month, year display formats.
·Added support for extended ASCII characters so eg French, German, Spanish accented
characters are now displayed correctly.
·Added 20Hz and 50Hz CAN output rates.
·Fixed bug where value and dynamic text gauges did not update correctly when an underlying
alarm bar changed.
·Made speed input setup on LDS4 more explicit.
·Added finer grain to the LDS4 brightness control.
06x01 - 11/12/09
·Added support for LDS3 Road Mode.
·Integrator outputs are backed up if added to the monitor screen.
06x02 - 17/02/10
·Added support for setting day of month - this can be used on a button hold for changing month
and year.
·Added support for Little Endian CAN streams. Requires v3.40 or later of the editor.
06x03 - 16/03/10
·Serial comms performance and reliability improved in PI System 3 mode.
06v04 - 30/03/10

3Revision History
© 2009 General Engine Management Systems Ltd.
·Added support for fastest lap delta and last lap delta.
06x05 - 14/04/10
·Special LDS4-PWM firmware created which produces a user-configurable PWM output on the
low side drive pin of
2.1.2 Release 05 Revision History
Known compatibility issues
·Requires version 3.31 or later of editing software.
·Requires v2.06 or later of Emerald.dll.
05x00 - 30/01/09 - Changes from Release 04
·Added Round Bitmap Tacho Gauge. This allows the pointer positions and offsets to be
specified but does not draw any part of the gauge other than the pointer. It also allows a bitmap
to be specified as the background thus allowing quite sophisticated gauges to be drawn.
·Added Odometer output.
·Add an extra lower limit section to bar tachos that can be set to be a different colour. The new
bar tacho also supports a flashing mode that if the upper and/or lower limits are passed, the
limit section or the entire bar can be flashed. Current flashing frequency is 1Hz.
·Support added for second serial comms channel on LDS4. LDS4 now has dedicated SMS1
support on Serial 1 and serial data stream support on Serial 2.
05x02 - 11/02/09
·Added a fast CAN transmit - this sends out the first 4 analogue inputs at 1kHz, big endian on
message 0x700.
·Analogue 3 is mapped as up/down button and can be used as a push button page select.
05x03 - 12/02/09
·Added support for real time clock in LDS4 Issue B boards.
·reduced the number of available CAN messages to 31 to protect the fast CAN Tx added in #78.
If more channels are required, specify an appropriate CAN mask in LDS4Editor.
·LDS4 Analogue 2 now used for up/ down button as per CD24.
05x04 - 24/03/09
·Added support for serial GPS data streams in standard NMEA format.
·Added on-board sector analysis. This uses GPS from a serial link to determine the car position
on-track.
·Made the OSA sector tolerance programmable. By default this is set to 0.003 minutes
(about +/- 6m).
·Added ability to display negative time information eg for split time differences.
·Fixed a bug that could erroneously trigger a lap start on power on.
·Interpolates latitude and longitude between GPS updates if a valid speed and heading are
present.
·Added support for GPS signals via CAN.
·Added a GPS Output that shows the GPS parameters (such as lat long etc) in a unified format.
·Written a StrToInt function for faster processing of GPS serial streams.

4 LDS4 Colour Display System

·Added support for low side driver output on PB20 on LDS4.
05x05 - 22/04/09
·Added round LED shift lights as an option to the limiter gauge.
05x07 - 27/04/09
·Added protection against out of range A2DOut indexing.
·Added short versions of FRAM functions.
·Removed some spurious code in EventMgr that could theoretically cause erroneous page
selects.
·Added means of calibrating LDS4 analogues 0 to 3 as sent out on the fast CAN message. This
adds a new event: ET_LDS4_CAL_MODE which toggles the dash between:
1) Not in cal mode
2) In cal mode (moving the analogues logs the min and max values)
3) Program mode (stores the Min and Max in the FRAM and reverts to mode 1
Once calibrated, the transmitted analogues will have a value between 1000 and 2000
although it can fall outside of this range if the calibration is incorrect.
05x08 - 05/05/09
·Changed the LDS4 fast CAN Tx to send A2 and A3 on words 1,2,3 and 4 of the fast CAN Tx
message.
05v10 - 12/05/09
·LDS4 calibrated analogues are filtered over 1 sec when in calibration mode.
05x11 - 02/06/09
·Fixed bug in TimeFilter output that could cause erroneous values to appear at certain update
rates.
·Add 2ms delay after initialising AMOLED panel to improve boot reliability.
05x12 - 05/06/09
·Explicitly turn AMOLED panel on as soon as controller has been reset. This fixes a very rare
occurrence of a full white screen on boot.
05x14 - 12/06/09
·Added message mask support.
05x15 - 26/06/09
·Fixed bug in OpenScreen and EventGauge that meant Keypad IDs greater than 127 did not
work. This affects setups where a lot of alarms have been added and are used for page
triggers.
05v16 - 07/08/09
·Added STOP_UNTIL_RESET event to stopwatch. Once received, the stopwatch will not start
running again unless a reset is received first. This works around setups that use a distance (eg
