      1.3 Run the Out-of-Box Demo

      Your FRDM-K66F comes loaded with a "bubble level" demo that leverages the on-board accelerometer. When the board is flat, the RGB LED is turned off, and when the board is tilted, the green or red LEDs gradually illuminate based on the degree of tilt on the X- and Y-Axis.

          2.2 Jump-Start Your Design with the Kinetis SDK

          The MCUXpresso SDK is complimentary and includes full source code under a permissive open-source license for all hardware abstraction an peripheral driver software. Learn about SDK.

          Click below to download a pre-configured SDK release for the FRDM-K66F.

          Get MCUXpresso SDK

          You can also use the online SDK Builder  to create a custom SDK package for the FRDM-K66F using the SDK builder.

          2.3 Install Your Toolchain

          NXP offers a complimentary toolchain called MCUXpresso IDE.

          Get MCUXpresso IDE

          Want to use a different toolchain?

          No problem! The MCUXpresso SDK includes support for other tools such as IAR , Keil  and command-line GCC .

          2.4 MCUXpresso Config Tools

          The MCUXpresso Config Tools is an integrated suite of configuration tools that guides users in creating new MCUXpresso SDK projects, and also provides pin and clock tools to generate initialization C code for custom board support.

          The MCUXpresso Config Tools are integrated within the MCUXpresso IDE, if using MCUXpresso IDE, no additional download is needed. If using another toolchain, please consider downloading the Config Tools here.

          2.5 PC Configuration

          Many of the example applications output data over the MCU UART so you'll want to make sure that the driver for the board's virtual COM port is installed. Before you run the driver installer, you MUST have the board plugged in to your PC.

          Download Driver

          With the serial port driver installed, run your favorite terminal application to view the serial output from the MCU's UART. Configure the terminal to 115,200 baud rate, 8 data bits, no parity and 1 stop bit. To determine the port number of the FRDM-K66F's virtual COM port, open the device manager and look under the "Ports" group.

          Not sure how to use a terminal application? Try one of these tutorials: Tera Term Tutorial, PuTTY Tutorial.

              3.2 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 FRDM-K66F: <sdk_install_directory>/boards/frdmk66f.

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

              3.3 Build, Run and Debug MCUXpresso SDK Examples

              If one or more of the example applications sound interesting, you're probably wanting to know how you can build and debug yourself. The Getting Started with MCUXpresso SDK 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.

                  4.2 Clone and Example Project from MCUXpresso SDK

                  Option A: Use the MCUXpresso IDE to clone an example project.

                  Option B: Use the MCUXpresso Config Tools to clone an existing MCUXpresso SDK example for use with third party IDEs.

                  4.3 Use the Pins Tools

                  Now, let's use the Pins tool that is part of the MCUXpresso Config Tools to show how to add a new GPIO pin to your project to blink an LED.

                  4.4 Use the Clocks Tool

                  Next, use the Clocks Tool that is part of the MCUXpresso Config Tools to change the clock settings and change the rate that the LED blinks.

                  4.5 Success

                  With the application modified, you will see the FRDM-K66F's blue LED slowly blinking. You can also view terminal output using the terminal program.
