2.1 Getting Started with the MCUXpresso SDK!

The MCUXpresso Software Development Kit (SDK) is complimentary and includes full source code under a permissive open-source license for all hardware abstraction and peripheral driver software.

Click below to download a pre-configured SDK release for the LPCXpresso54608, which includes versions for MCUXpresso IDE, Keil MDK and IAR EWARM.

You can also use the online MCUXpresso web tool to create a custom SDK package for the LPCXpresso54608 using the SDK builder.

2.2 Install your toolchain

NXP offers a free, GNU/Eclipse based toolchain called MCUXpresso IDE.

Want to use a different toolchain?

No problem! The MCUXpresso SDK includes support for other tools such as IAR and Keil.

To set up your LPCXpresso54608 for use with 3rd party tools, first install LPCScrypt in order to install the board’s device drivers. The video below shows how to use LPCScrypt to program your board’s debug probe using this utility.

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.

2.4 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:

Build, Run

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 your board, the LPCXpresso54608 (<SDK_Install_Directory>/boards/lpcxpresso54608).

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

3.2 Build, Run and Debug 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 SDK v.2.0 for LPC546xx 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?

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.

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. 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 muxing

// Configure clock source

// Initialize the UART terminal

PRINTF("\r\nRunning the myProject project.\n");

// Enable GPIO port for the red LED

for (;;)

delay = 5000000;

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.
