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 T

E Build Output C Find in Files Browser Simulation 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 Electrocomponents plc Page 6 EDP CM LPCxxxx Getting Started V3 11 RS 4 1 Creating a new Project 5 Click on New Vision Project from the Project menu and navigate to your project folder containing your source files Type in a project name and click on Save You will now be asked to select a target MCU device In this case select NXP and then the part number from the drop down list Right click on Source Group 1 in the Project pane expanded from Target 1 and then on Add Files to Group Select and Add all your source c files You can rename Target 1 and Source Group 1 and create other groups for other files by right clicking on Target 1 and then clicking on Manage Components Double click on file system _LPCxxxx c and select the Configuration Wizard tab Locate the Power Control for Peripherals Register and tick the boxes of peripheral systems used by your
4. 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 uVision 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 Vision 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 uVision 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 itil A HAN mee SS ua a wa BAR WRK BRR LEAR BRR ayy MER RRR 3 RNR kuy y a rs ors V F y Ae zi i igi i sa abe wa on t J Ay e e e o _ _ _ oe e o STHTTHTTLERLALL LLL EARLE LARP ER EED mi ee
