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pdf
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Revxx

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)

2. Prepare to run the ‘Hello World’ Program
ProgramdevelopmentisperformedonaPCrunningsuitablesoftware,andaplug‐inhardware
‘dongle’isrequiredasaprogramming/debuginterfacebetweenthePCandtheCMmodule.

2.1 Software requirements
Tobuild,downloadandrunyourfirstprogramyouwillneedtohaveasuitable
IntegratedDevelopmentEnvironment(IDE)runningonaPC.Ifnecessary
downloadKeilµVision4forARMprocessorsfromtheKeilwebsite.Thisisa
full‐featuredfreetrialversionthatislimitedto32Kbytesofoutputcode.You
canupgradetothefullversionlaterortryoneofthealternativesdiscussedin
anappendixtotheUserManual.TheIDEhandlesallaspectsofcode
productionasitcontainsasourcecodeeditor,assembler,Ccompiler,Flash
programmeranddebugtools.

2.2 Hardware requirements
TheKeilIDEneedsahardwareprogramming/debugdonglewhichallowsthe
CMmoduletobelinkedviaUSBtotheIDErunningonthePC.Ifyoualready
runKeilµVisionthenyoushouldalreadyhavetheinterfaceintheformofa
ULINK2module.Ifnot,thenasuitableunitcanbeobtainedfromRSunderthepartno.703‐9241.

ThesoftwareinsidethedongleisupgradedautomaticallybyKeilµVisionwhenitispluggedintothe
hostcomputer.ItsupportsclassicARM7/ARM9architecturesaswellasthelaterCortexdevices.
JTAGandSWDarebothsupported.

folder.Doubleclickon‘Hello_World’toloadtheprojectfiles.
•Thescreenwillnowappearasbelow:


NotethatthefolderalreadycontainsallthenecessarysourcecodefilestogetherwiththeBuildfiles
producedbytheIDE.TodemonstratetheprocedurewewillnowperformtheBuildandLink
operations.

3.2 Build the Project
•Click the Rebuild button on the Build toolbar (see picture below). The various files are
compiled and linked, progress being reported in the Build Output pane.
•If there are any compilation errors they will be reported here and linking will not take place.
Double clicking on a particular error message will take you to the offending line of source code
in the edit pane above.

3.3 Download and program target Flash memory
•IfzeroerrorsarereportedthenthecodecanbedownloadedtothetargetMCUand
programmedintoitsFlashmemory.ClickontheDownloadbuttonontheBuildtoolbar.
•PresstheResetbuttonontheEDPBaseBoardandoneofthetwoyellowUserLEDsonthe

4. Build your own Project
Theprocedureforbuildingandprogrammingyourownprojectisexactlyasoutlinedaboveusing
yourownprojectfoldercontainingsource(.c)andheader(.h)files.

TheHelloWorldprogramdoesnotuseanyEDPApplicationModulehardwarebutyourprojects
probablywill,sothenecessarydriverswillneedtobeincludedinyourfolder.Downloadthesefrom
theEDPwebsite.NotethatMCU‐specificdriverswillalsoberequired:seeexampleabove.
