The following article explains all necessary steps to create an Embedded Wizard UI application suitable for the LPCXpresso54608 development board. Please follow these instructions carefully and step by step in order to ensure that you will get everything up and running on your target. Moreover, this article assumes, that you are familiar with the basic concepts of Embedded Wizard.

Prerequisites

First of all, you need the following hardware components:

LPCXpresso54608 development board from NXP

USB cable to connect the board with your PC

Make sure that you have got the following software packages:

Embedded Wizard Studio Free or Embedded Wizard Studio Pro

Embedded Wizard NxpLpc Platform Package

Embedded Wizard Build Environment for LPCXpresso54608

TIP

If you want to use the Free edition of Embedded Wizard Studio and the NxpLpc Platform Package, please register on our website and select the target LPCXpresso54608. Then you can download the above software packages.

All customers who licensed Embedded Wizard can visit our download center to get the above software packages.

Installing Tools and Software

Step 1: Install the latest version of Embedded Wizard Studio.

Step 2: Install the Embedded Wizard NxpLpc Platform Package.

Step 3: Visit the NXP website and build/download the MCUXpresso Software Development Kit (SDK) for LPCXpresso54608. If you want to use FreeRTOS, make sure to select the operating system in the SDK configuration. Write down the installation path.

Step 4: Download the MCUXpresso Integrated Development Environment (IDE) from NXP and install it. Write down the installation path.

Step 5: Connect your development board with your PC via USB (make sure to use the USB Debug Link connector) and remove jumper JP5 from the board. Otherwise flashing your software is not possible.

Step 6: Create your NxpLpc project directory (e.g. \NxpLpc) at any location in your local file system (e.g. in {UserDocumentFolder}).

Step 7: Unpack the provided Embedded Wizard Build Environment for LPCXpresso54608 into the subdirectory {UserDocumentFolder}\NxpLpc\LPCXpresso54608

Step 8: Take a text editor and open the file devenv.cmd that you will find in the subdirectory \Build of the Build Environment. At the beginning of the file, the following environment variables have to be set to the installation paths of the different software components:

MCUXpressoIDE_PATH - Path of your installed MCUXpresso IDE (Step 4).

SDK_PATH - Path of your installed MCUXpresso SDK (Step 3).

Exploring the Build Environment

The provided Embedded Wizard build environment for LPCXpresso54608 contains everything you need to create, compile, link and flash an Embedded Wizard UI application for the LPCXpresso54608 target. After unpacking, you will find the following subdirectories and files:

\Build - This folder contains the necessary stuff to build your UI application: the make utility and the script file StartBuildEnvironment.bat to start a windows command line to build the application. Don't forget to set the path of your installed software packages into the file devenv.cmd.

\Examples - This folder contains a set of demo applications. Each example is stored in a separate folder containing the entire Embedded Wizard UI project. Every project contains the necessary profile settings for the LPCXpresso54608 target. The following samples are provided:

\HelloWorld - A very simple project that is useful as starting point and to verify that the entire toolchain, your installation and your board is properly working.

\ColorFormats - This project demonstrates that every UI application can be generated for different color formats: RGBA8888, RGB565, Index8 and LumA44.

\ScreenOrientation - This demo shows, that the orientation of the UI application is independent from the physical orientation of the display.

\DeviceIntegration - This example shows the integration of devices into a UI application and addresses typical questions: How to start a certain action on the target? How to get data from a device?

\GraphicsOperations - This application demonstrates the graphics performance of the target by using sets of basic drawing operations that are executed permanently and continuously.

\BrickGame - The sample application BrickGame implements a classic "paddle and ball" game. In the game, a couple of brick rows are arranged in the upper part of the screen. A ball travels across the screen, bouncing off the top and side walls of the screen. When a brick is hit, the ball bounces away and the brick is destroyed. The player has a movable paddle to bounce the ball upward, keeping it in play.

\ClimateCabinet - The ClimateCabinet demo shows the implementation of a control panel for a climatic exposure test cabinet. The user can define a heating time, a nominal temperature and humidity, a dwell time and the final cooling time.

\PaperCutter - This demo shows the implementation of a paper cutting machine, where the user can define the pagination and format of the paper as well as the cutting speed and the amount of papers. The application contains many rect effects and fade-in/fade-out effects to change dynamically the layout of the screen.

\WashingMachine - This demo shows the implementation of a washing machine with a couple of fancy scrollable list widgets to choose the washing program and parameters. The speciality of this sample application is the magnification effect of the centered list items and the soft fade-in/fade-out effects.

\WaveformGenerator - This WaveformGenerator demo application combines waveforms with different amplitudes and frequencies. The implementation shows the usage of the class Charts::Graph to paint a list of coordinates.

\Misc - This folder contains some helper modules for printing debug messages and the memory manager used for the Embedded Wizard UI applications.

\PlatformPackage - This folder contains the necessary source codes and/or libraries of the NxpLpc Platform Package: Several Graphics Engines for the different color formats (RGBA8888, RGB565, Index8 and LumA44) and the Runtime Environment (in the subdirectory \RTE).

\TargetSpecific - This folder contains all configuration files and platform specific source codes. The different ew_bsp_xxx files implement the bridge between the Embedded Wizard UI application and the underlying board support package (NXP hardware drivers) in order to access the display, the serial interface and the clock.

\Template - This folder contains a ready-to-use project to compile and link an Embedded Wizard generated UI application. It is used for all provided examples and it can be used to build your own UI applications.

\GeneratedCode - This folder is used to receive the generated code from an Embedded Wizard UI project. The template project is building the UI application out of this folder. You can create your own UI project and generate the code into the subdirectory \GeneratedCode without the need to adapt the project.

\Project - This folder contains the prepared projects for GCC (make).

\Source - This folder contains the main.c file, a configuration file for FreeRTOS and the device driver C/H files used for the DeviceIntegration example.

Creating the UI Examples

For the first bring up of your system, we recommend to use the example 'HelloWorld':

Example 'HelloWorld' within Embedded Wizard Studio.

The following steps are necessary to generate the source code of this sample application:

Navigate to the directory \Example\HelloWorld.

Open the project file HelloWorld.ewp with your previously installed Embedded Wizard Studio. The entire project is well documented inline. You can run the UI application within the Prototyper by pressing Ctrl+F5.

To start the code generator, select the menu items BuildBuild this profile - or simply press F8. Embedded Wizard Studio generates now the sources files of the example project into the directory \Template\GeneratedCode.

Compiling, Linking and Flashing

The following steps are necessary to build and flash the Embedded Wizard UI sample application using the GCC ARM embedded toolchain:

Navigate to the directory \Build.

Open StartBuildEnvironment.bat - as a result, a windows command line window should open. In case there are error messages, please edit the file devenv.cmd and set the path variables according your installation paths of the different software packages

Now start compiling, linking and flashing:

make make install

If everything works as expected, the application should be built and flashed to the LPCXpresso54608 target.

Example 'HelloWorld' running on LPCXpresso54608 development board.

All other examples can be created in the same way: Just open the desired example with Embedded Wizard Studio, generate code and rebuild the whole application using simply:

make install

Creating your own UI Applications

In order to create your own UI project suitable for the LPCXpresso54608 target, you can create a new project and select the LPCXpresso54608 project template:

As a result you get a new Embedded Wizard project, that contains the necessary Profile attributes suitable for the LPCXpresso54608 development board:

The following profile settings are important for your target:

The attribute PlatformPackage should refer to an installed NxpLpc Platform Package.

The attribute ScreenSize should correspond to the display size of the LPCXpresso54608 development board.

The attributes FormatOfBitmapResources and FormatOfStringConstants can be set to DirectAccess in case that the resources should be taken directly from flash memory. By default these attributes are set to Compressed.

The attribute OutputDirectory should refer to the \Template\GeneratedCode directory within your Build Environment. By using this template, it will be very easy to build the UI project for your target.

The attribute CleanOutputDirectories should be set to true to ensure that unused source code within the output directory \Template\GeneratedCode will be deleted.

Now you can use the template project in the same manner as it was used for the provided examples to compile, link and flash the binary.

After generating code, please follow these steps, in order to build your own UI application:

Start the batch file 'StartBuildEnvironment.bat'. Again, a windows command line window should open.

Start compiling, linking and flashing:

make install

Most of the project settings are taken directly out of the generated code, like the color format or the screen orientation. Only a few additional settings can be configured directly within the Makefile, like the usage of QSPI flash memory or the usage of the FreeRTOS operating system.

Console output

In order to receive error messages or to display simple debug or trace messages from your Embedded Wizard UI application, a serial terminal like 'Putty' or 'TeraTerm' should be used.

As soon as you connect your LPCXpresso54608 target with the PC via USB, a LPC-LinkII UCom Port (COMx) appears within your system device list. Open the device manager to get the number of the installed COM port.

Now you can open your terminal application and connect it via COMx with the following settings: 115200-8-N-1

This terminal connection can be used for all trace statements from your Embedded Wizard UI applications or for all debug messages from your C code.
