4.1 Get SDK Project Generator

Let's create our own project and make a simple SDK-based application. NXP provides an intuitive, simple project generation utility that allows creation of custom projects based on the Kinetis SDK.

Get Project Generator

4.2 Run the SDK Project Generator

After extracting the ZIP file, open the utility by clicking on the KSDK_Project_Generator executable for your computer's operating system. Point the tool to your SDK installation path, name your project, and select the board that it uses as a reference. Click on the Quick Generate button to finish.

4.3 Open Your Project

Your new project will be located in <sdk_install_directory>/examples/frdmk64/user_apps</sdk_install_directory>. Open the project in your toolchain of choice by using the same process described in section 3.2.

4.4 Write Some Code

Now, let's make our new project do something other than spin in an infinite loop. The SDK examples provide a board support package (BSP) to do various things specific to the board, including macros and definitions for items such as LEDs, switches and peripheral instances. To keep things simple, lets make the LED blink using the BSP macros.

Update the main() function in your project's main.c file with the following code:

volatile int delay;
// Configure board specific pin muxingBOARD_InitPins();
// Configure clock sourceBOARD_BootClockRUN();
// Initialize the UART terminalBOARD_InitDebugConsole();PRINTF("\r\nRunning the myProject project.\n");
// Enable GPIO port for the red LEDCLOCK_EnableClock(kCLOCK_PortE);PORT_SetPinMux(BOARD_LED_RED_GPIO_PORT, BOARD_LED_RED_GPIO_PIN, kPORT_MuxAsGpio);LED_RED_INIT(LOGIC_LED_OFF);for (;;){LED_RED_TOGGLE();delay = 5000000;while(delay--);}

4.5 Build, Download, Run

With the changes made to your main() function, build your application. Once the build is complete, download the application to your board.

If you need help figuring out how to build, download or run an application, reference your tool-specific guide from section 3.2.

4.6 Success

With the application downloaded, you will see the FRDM-KE15Z's red LED blinking. You can also view terminal output using PRINTF.

Running a Demo Using IAR

Build an Example Application

The following steps will guide you through opening the led_output application. These steps may change slightly for other example applications as some of these applications may have additional layers of folders in their path.

  1. If not already done, open the desired example application workspace. Most example application workspace files can be located using the following path:

    <install_dir >/boards/<sdk_board_name >/<example_type>/<application_name>/iar</application_name></example_type></sdk_board_name ></install_dir >

    Using the hello_world demo as an example, the path is:

    <install_dir>/boards/LPCXpresso54S018/driver_examples/gpio/led_output/iar</install_dir>

  2. Select the desired build target from the drop-down. For this example, select the “hello_world – Debug” target.

  3. To build the application, click the “Make” button, highlighted in red below.

  4. The build will complete without errors.:

Run an Example Application

The LPCXpresso54S018 board comes loaded with the CMSIS-DAP debug interface from the factory. Connect the development platform to your PC via USB cable to J8 “Debug Link”.

  1. Click the "Download and Debug" button to download the application to the target.

  2. The application is then downloaded to the target and automatically runs to the main() function.

  3. Run the code by clicking the "Go" button to start the application.

Running a Demo Using Keil MDK/µVision®

Install CMSIS device pack

After the MDK tools are installed, Cortex® Microcontroller Software Interface Standard (CMSIS) device packs must be installed to fully support the device from a debug perspective. These packs include things such as memory map information, register definitions and flash programming algorithms. Follow these steps to install the appropriate CMSIS pack.

  1. Open the MDK IDE, which is called µVision. In the IDE, select the "Pack Installer" icon.

  2. 2. In the Pack Installer window, navigate to the section with the LPC packs (they are in alphabetical order). The Kinetis packs start with "Keil::LPC" and are followed by the MCU family name, for example "Keil::LPC54000". Because this example uses the LPCXpresso54S018 platform, the LPC54000 family pack is selected. Click on the "Install" button next to the pack. This process requires an internet connection to successfully complete.

  3. After the installation finishes, close the Pack Installer window and return to the µVision IDE.

Build the Example Application

The following steps will guide you through opening the gpio_led_output application. These steps may change slightly for other example applications as some of these applications may have additional layers of folders in their path.

  1. If not already done, open the desired demo application workspace in:

    <install_dir >/boards/<sdk_board_name >/<example_type>/<application_name>/mdk</application_name></example_type></sdk_board_name ></install_dir >

    The workspace file is named <application_name>.uvmpw, so for this specific example, the actual path is: </application_name>

    <install_dir>/boards/LPCXpresso54S018/driver_examples/gpio/led_output/mdk/gpio_led_output.uvmpw</install_dir>

  2. To build the demo project, select the "Rebuild" button, highlighted in red.
