1. Introduction
To
get
the
most
out
of
the
EDP
platform
it’s
important
to
understand
the
concept
of
the
EDP
system
correctly.
This
is
detailed
in
the
user
manual
for
the
Base
Boards
which
can
be
downloaded
as
a
file
RS
EDP
‐
BB
‐
SystemBaseBoard
User
Manual
Vx
,
from
the
RS
EDP
website.
The
base
boards
come
in
both
2
position
and
4
position
formats
and
share
a
common
user
manual.
Please
read
this
manual
to
get
an
understanding
of
the
system.
Each
of
the
Command
Modules
(CM)
and
Application
Modules
(AM)
has
its
own
user
manual,
so
again
these
documents
must
be
read
to
get
an
understanding
on
how
to
use
the
modules.
Each
of
the
boards
comes
with
its
own
suite
of
software
to
fully
exercise
the
EDP
Application
Modules
and
the
peripherals
available
on
the
MCU
device.
An
EDP
system
usually
consists
of
one
Command
Module
and
one
or
more
Applications
Modules
plugged
into
a
Base
Board.
A
minimum
system
just
has
a
Command
module
and
Base
Board,
for
example
a
simple
web
server
operating
through
an
Ethernet
connection.
The
Command
Module
dictates
whether
the
whole
system
uses
a
supply
voltage
of
+3.3V
or
+5.0V.
This
particular
CM
module
use
a
+3.3V
microcontroller
(MCU)
and
so
the
board
is
configured
as
such.
The
user
can
check
the
Vcc_CM
signal
on
the
Base
Board
break
‐
out
header
to
confirm
the
system
voltage.
There
are
100
pins
on
the
MCU
and
these
are
connected
via
various
link
options
to
the
Base
Board.
The
Base
Board
then
routes
these
signals
to
the
Application
Modules
thereby
allowing
the
CM
Module
to
communicate
with
the
Application
Modules.
As
many
of
the
MCU
pins
have
more
than
one
function
it
can
make
the
mapping
of
the
connections
rather
complex
so
there
are
additional
support
documents
available
to
help
you
with
this.
The
first
is
the
Pin
Allocation
Spread
Sheet.
One
spread
sheet
is
available
for
each
of
the
CM
Modules.
The
one
for
the
NXP
family
of
ARM
‐
based
modules
is
called:
Pin
Allocation
‐
100
pin
NXP
Command
Module

This
spreadsheet
also
forms
part
of
the
User
Manual
for
the
LPCxxxx
CM
module.
It
details
which
pins
are
mapped
to
the
Base
Board
backplane
and
the
various
link
options
which
need
to
be
configured
to
connect
them
accordingly.
To
get
an
appreciation
of
how
the
Application
Modules
are
mapped
to
the
backplane
and
how
the
CPU
Module
can
connect
to
them,
a
Mapping
Aid
exists.
The
one
for
the
LPC1768
module
is
called:
Mapping
Aid
RS
‐
EDP
NXP
LPC1768
Rev
xx
(Name
may
vary
slightly
for
other
NXP
modules)
This
mapping
aid
also
forms
part
of
the
User
Manual
for
the
LPC
Module
and
at
a
glance
you
can
see
what
resources
are
required
to
get
the
best
out
of
each
Application
Module.
Other
useful
documents
you
will
need
are
the
circuit
diagrams
for
the
modules
you
wish
to
use.
These
are
contained
in
the
back
of
each
user
manual.
So
before
you
start
to
use
the
RS
EDP
system
make
sure
you
have
to
hand
the
following
documents:
•
Base
Board
User
Manual
•
Appropriate
CM
module
User
Manual
•
Application
Module
User
Manuals
(as
required)
