    1.4 Run the Out-of-the-Box Demo

    Your LPCXpresso55S69 board comes loaded with a program to verify that target MCU is running.

    The application is active if the green LED in the RGB-LED flashed with a 1 Hz rate.

    1.5 Switch and LED Test

    1. Press the [WAKEUP] button. Verify that the blue LED in the RGB-LED is constant on while pressing
    2. Press the [USER] button. Verify that the green LED in the RGB-LED is constant on (with only short off-flashes)
    3. Press the [ISP] button. Verify that the red LED in the RGB-LED is constant on while pressing
    4. Press the [RESET] button. Verify that the RGB-LED turns off while pressing

    1.6 Audio Test

    For this test you need:

    • A line level audio source like a PC, smartphone or tablet
    • A stereo audio cable to connect the audio source to the LPC55S69 board
    • A stereo audio headphones or speaker

    Instructions

    1. Plug in the audio source to the [Audio Line In] connector
    2. Connect headphones or speaker to the [Audio Line Out] connector
    3. Play audio from device connected as input
    4. Verify you listen to the audio on the headphones

      2.1 Jump Start Your Design with the MCUXpresso SDK

      Want to learn about SDK?

      Get MCUXpresso SDK

      You can also use the online SDK Builder to create a custom SDK package for the LPC55S69-EVK using the SDK builder The board name for the SDK is LPCXpresso55S69 SDK Builder.

      2.2 Install Your Toolchain

      NXP offers a complimentary toolchain called MCUXpresso IDE.

      Get MCUXpresso IDE

      Want to use a different toolchain?

      2.3 MCUXpresso Config Tools

      The MCUXpresso Config Tool is an integrated suite of configuration tools that guides users in creating new MCUXpresso SDK projects, and provides pin and clock tools to generate initialization C code for custom board support. It is fully integrated into MCUXpresso or you can download a seperate tool. Click the Get MCUXpresso Config Tools below to get the Config Tools installer.

      Get MCUXpresso Config Tools

      To learn more about the basic interactions between the tools wh working with either an imported MCUXpresso SDK example project or creating a new project within the IDE, watch this three-part video series.

        2.5 Serial Terminal

        Most of the MCUXpresso SDK examples set up for IAR and Keil tools use the MCU UART for printf output, and this is also an option for the MCUXpresso IDE. If you are not sure how to use a terminal application try one of these tutorials:

          3.1 Explore the MCUXpresso SDK Example Code

          The MCUXpresso SDK comes with a long list of example applications code. To see what's available, browse to the SDK boards folder of your SDK installation and select LPCXpresso55S69.

          <SDK_Install_Directory>/boards/LPCXpresso55S69

          To learn more about specific example code, open the readme.txt file in an example’s directory.

          3.2 Building and Debuging MCUXpresso SDK Examples

          If one or more of the demo applications or driver examples sounds interesting, you're probably wanting to know how you can build and debug yourself. The Getting Started with MCUXpresso SDK guide provides easy, step-by-step instructions on how to configure, build, and debug demos for all toolchains supported by the SDK.

          Use the guide below to learn how to open, build and debug an example application using the MCUXpresso IDE.

          Using a different toolchain?

          This demo is also available for IAR and KEIL.

          3.3 Building and Debuging MCUXpresso SDK Examples

          Now its time to plug in the board to debug your project:

          1. Make sure the DFU jumper J4 is removed
          2. Plug the micro USB cable from the PC into the Debug Link micro USB connector as shown
          3. In the Project Exporer window in MCUXpresso select your project
          4. In the Quick Start Panel click on Debug
          5. Choose the CMSIS-DAP debug interface
          6. Choose Core 0 for the target core
          7. Hit Resume to get the code running after the breakpoint at the beginning of main ()

          More details can be found in the SDK getting started documents found in the SDK folder
