LIN Bus applications
Baby-LIN/HARP-5 devices are used to control a LIN bus equipped ECU‘s, e.g.
wiper motors, climatic actuators, button modules, interieur lights etc.
The base concept of LIN defines, that there is always one master on a LIN Bus
and several LIN Slave nodes.
The Master sends command frames, carrying signals like set values, vehicle
status information (vehicle speed, temperature, …).
The Master also fetches some information from the slaves by issueing read
frames, which will be reponded by the slave node.
The read frame will contain signals from the slave e.g. actual motor speed, park
contact state, motor temperature, error information etc.

Typical starting point
LDF
The LDF (Lin Description File) describes the representation of the
information (signals) interchanged by master and slave (e.g. motor). It
contains descriptions of all nodes, frames and signals available on a
specific LIN Bus.
The LDF file is typically the starting point, when dealing with LIN.
So this is one of the first questions, you need to answer:
Do I have an appropriate LDF file available?
Where can I source it ?
If you have to do any LIN related job, ask the principal to supply the
appropriate LDF file !

LINWorks Session Conf
The Baby-LIN/HARP needs some more information than
given in the LDF file, to allow a bus simulation.
So the Baby-LIN needs to know, which nodes should be
emulated, and which nodes will be present and connect in
real.
LDF
Additional some funtional logic for the simulation can be
necessary.
All this can be defined by the LINWorks component
SessionConf.
LINWorks
SessionConf
First the LDF is imported into the SessionConf.
Then after minimal adding emulation setup the configuration
will be stored in a SDF file.
Of course the Session Conf can also open existing
SDF files to allow for modifications.

LINWorks Simple Menu
A SDF file can be executed by a Baby-LIN or a HARP device.
With a Baby-LIN the SDF is downloaded into the device by the
LINWorks SimpleMenu component.
LDF
Then the simulation can be started from the Simple Menu screen, and
signals can be watched or edited in realtime, macros or
macroselections can be executed.

USB
Optionally the SDF can be stored persistently in the Baby-LIN device flash memory, It then
can be auto executed every time the device is powered up.
Once installed in the device, the SDF can be executed without a PC connected
to the Baby-LIN => Stand-alone operation !

Typical Application
The HARP workflow is a little bit different, as the
SDF file is not downloaded via USB, but it is copied
on the SD-Card
So the PC needs a SD card writer installed!

HARP-5 operation
The HARP can hold multiple SDF files on the SD-card.
The user can select one of them for operation.
If available, you also can open subdirectories and select a SDF file
from there.
The head line indicates, whether the item under the inverted line
cursor is an SDF-V2 or SDF V3 file or a subdirectory.

HARP-5 operation
After selection of the SDF file, you can
choice to run in SDF-Menu or
KEYBOARD menu.
The bus will be started by execution of
autostart macro (if defined in SDF file)
or by Start key in SDF Menu
SDF Menu holds
monitored and editable
signals, macros and
macro selections.
Content is defined in
SessionConf Simple
Menu section.

Folie-9
KEYBOARD menu
holds up to 5 monitored
signals, but by default
only 2 of the are shown.
Other display area is
used to show key
descriptions.
HARP-5 SDF Menu
SDF SimpleMenu section definitions
will be visible in HARP-5 SDF-Menu
Editable signals and macro selections
can be changed after pressing right
arrow key and selecting new value with up/down arrow keys.
Macros will be executed by pressing the OK key.
Signals can be shown as raw values or in physical dimensions.
A short press on the ON/OFF key will toggle the display mode
(raw/physical encoded)

shown in the display. here
F1 = START
F2 = RESTART
F3 = SLEEP
HARP-5 Keyboard Menu
Keyboard menu is defined in 2 parts
Key actions are defined in the SDF Events Section.
Monitored signals and key descriptions are defined in
the SDF Device-specific options section.
Toggle between 2 signal and 5 signal display by long
press on the MENU key.
Short press on the MENU key will open the LOGGER
menu, to setup data logging features
