1. Plug It In

Let's take your TWR-KL82Z72M for a test drive! You have the choice of watching the sequence in a short video or following the detailed actions list below.

1.1 Attach the USB Cable

1.2 Run the Out-of-Box Demo

Your TWR-KL82Z72M comes loaded with a "bubble level" demo that leverages the on-board accelerometer. After the USB cable is plugged in, all the LEDs on the board will flash. Then when the board is flat, the RGB LED is turned off, and when the board is tilted, the yellow or blue LEDs gradually illuminate based on the degree of tilt on the X- and Y-axis.

Installing software for the TWR-KL82Z72M

2.1 Jump Start Your Design with the Kinetis SDK

Want to learn about SDK

The Kinetis 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 the KL82Z standalone SDK package

Get SDK

2.2 Install Your Toolchain

NXP® offers a complimentary toolchain called Kinetis Design Studio (KDS).

Get Kinetis Design Studio

Want to use a different toolchain?

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

2.3 Tool Update

If using Kinetis Design Studio or Arm GCC tool chains, the latest Segger J-Link software tools need to be downloaded and installed. This update is required for those tools to support the KL80 family. Ensure you install this update after installing the IDE of your choice.

First, download the latest “Software and documentation pack”, at least version 5.02, from Segger

Then Install the software and at the end of the installation, there will be a dialog box asking to update installed IDEs. Make sure the KDS 3.0.0 IDE is checked if using Kinetis Design Studio.

2.4 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 115200 baud rate, 8 data bits, no parity and 1 stop bit. To determine the port number of the TWR-KL82Z72M's virtual COM port, open the device manager and look under the "Ports" group.

Build and Run SDK Demos on the TWR-KL82Z72M

3.1 Explore the SDK Example Code

The Kinetis SDK comes with a long list of demo applications and driver examples. To see what's available, browse to the SDK 'examples' folder of your SDK installation and select your board, the TWR-KL82Z72M (<sdk_install_directory>/examples/twrkl82z72m</sdk_install_directory>).

To learn more about demo applications or driver examples, open the Kinetis SDK Demo Applications User's Guide, located in <sdk_install_directory>/doc</sdk_install_directory>.

3.2 Build, Run and Debug 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 Kinetis 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 Kinetis Design Studio (KDS) IDE.

Create an Application for the TWR-KL82Z72M

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 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 the Quick Generate button to finish.

4.3 Open Your Project

Your new project will be located in /examples/twrkl82z72m/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: 


let copy = ""
  let copied = ""
  let lang = NXP.locale ? NXP.locale : "en"
  switch (lang) {
      case "en":
          copy = "Copy"
          copied = "Copied"
          break
      case "zh":
          copy = "复制"
          copied = "已复制"
          break
      case "cn":
          copy = "复制"
          copied = "已复制"
          break
      case "ja":
          copy = "コピー"
          copied = "コピー済"
          break
      default:
          break
  }

  volatile int
  delay;
  // Configure board specific pin muxing
    hardware_init();
  
  // Initialize the UART terminal
    dbg_uart_init();
  PRINTF("
  \r\nRunning the myProject project.\n
  ");
  // Enable GPIO port for LED1
    LED1_EN;
  for
  (;;)
    {
  
  LED1_ON;
    
  
  delay = 5000000;
    
  
  while(delay--);
    
  
  LED1_OFF;
    
  
  delay = 5000000;
    
  
  while(delay--);
    class="instruction"
    }

4.5 Build, Download, Run

With the changes made to your main() function, build your application. Remember to build the SDK platform library first if you did not build any of the other SDK examples in the previous steps. 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 TWR-KL82Z72M's red LED blinking. You can also view terminal output using PRINTF.

Tera Term Tutorial

Tera Term is a very popular open source terminal emulation application. This program can be used to display information sent from your NXP development platform's virtual serial port.

  1. Download Tera Term from SourceForge. After the download, run the installer and then return to this webpage to continue

    2. Download

  2. Launch Tera Term. The first time it launches, it will show you the following dialog. Select the serial option. Assuming your board is plugged in, there should be a COM port automatically populated in the list
  3. Configure the serial port settings (using the COM port number identified earlier) to 115200 baud rate, 8 data bits, no parity and 1 stop bit. To do this, go to Setup → Serial Port and change the settings
  4. Verify that the connection is open. If connected, Tera Term will show something like below in it's title bar.
