FRDM-K64F

The Freedom-K64F is an ultra-low-cost development platform for Kinetis K64, K63, and K24 MCUs.

Overview¶

The Flagship FRDM-K64F has been designed by NXP in collaboration with mbed for prototyping all sorts of devices, especially those requiring optimized size and price points. The board is well sized for connected applications, thanks to its power efficient Kinetis K64F MCU featuring an ARM® Cortex®-M4 core running up to 120MHz and embedding 1024KB Flash, 256KB RAM and lots of peripherals (16-bit ADCs, DAC, Timers) and interfaces (Ethernet, USB Device Crystal-less and Serial). The Kinetis K64 MCU family remains fully software, hardware and development tool compatibility with Kinetis MCU and Freedom board families. It is packaged as a development board including extension headers compatible with Arduino R3 shields and includes a built-in USB Debug and Flash Programmer.

Board Block Diagram¶

The graphic below gives an overview of the board features and the connection between the target MCU and the on-board components and connectors

Board Pinout¶

Component Pinout¶

Following figure indicates the Kinetis K64F signal connections with the board components (RGB LED, Motion Sensor) and extension connectors (uSD Card, Bluetooth and RF headers).

Arduino and NXP Header Pinout¶

Freedom board headers enable up to 64-pins and give access to most of the Kinetis K64F signals

• Outer row pins deliver right signals to meet Arduino R3 standard
• Inner row is connected to up to 32 additional Kinetis K64F pins
  
  
  

The FRDM-K64F is fully supported in the mbed platform, so it gets access to the free tools and SDK that provides experienced embedded developers with powerful and productive tools for building proof-of-concepts. The pinout above shows the commonly used interfaces and their locations. Note that all the numbered pins (PT_XX) can also be used as DigitalIn and DigitalOut interfaces.

Pin names¶

• mbed pin-names
• K64F/FRDM-K64F revE3 pin-multiplexing

PC Configuration¶

Your mbed Microcontroller can appear on your computer as a serial port. On Mac and Linux, this will happen by default. For Windows, you need to install a driver:

From a host PC to communicate with mbed you will need a terminal application. This allows the mbed Microcontroller to print to your PC screen, and for you to send characters back to your mbed.

• Terminals - Using Terminal applications to communicate between the Host PC and the mbed Micrcontroller

Some terminal programs (e.g. TeraTerm) list the available serial ports by name. However, if you do need to know the identity of the serial port so that you can attach a terminal or an application to it:

	'''Windows'''		'''Mac'''		'''Linux'''
	Find the identity of the COM port by opening ''Device Manager''. To do this navigate ''Start -> Control Panel -> System -> Hardware -> Device Manager''.		To find the device name under Mac OS X, use the command ''ls /dev/tty.usbmodem*''		To find the device name under Linux, use the command ''ls /dev/ttyACM*''

Debug Interface Firmware Update¶

A new interface firmware image is necessary to mbed-enable NXP FRDM boards

The latest Arm Mbed DAPLink interface firmware for FRDM-K64F is available at (click the image):

Get Started with mbed¶

First board connection¶

Use the USB lead to connect your mbed to a PC. The status light will come on, indicating it has power. After a few seconds of activity, the PC will recognise the mbed Microcontroller as a standard USB drive.

Windows XP example	Mac OS X example

Connect to mbed¶

Go to the new USB Drive, and click MBED.HTM to open it in a web browser.

If you do not have an mbed account, choose "Signup", and create your mbed Account. Otherwise, log in with your normal username and password.

This will give you access to the website, tools, libraries and documentation.

Flash a project binary¶

1. Download a (.bin) to the FRDM Platform¶

Download the appropriate "Hello World!" binary:

• NXP FRDM-K64F: HelloWorld_K64F.bin

Note: the source code for this program will be seen in the next section.

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

2. Press the Reset Button¶

When the Reset Button in pressed, the newest program on the mbed Microcontroller Disk will be loaded in to the Microcontroller FLASH memory. The Status LED will flash as this happens.

When the program is has been loaded onto the microcontroller, it will then start it running.

3. Run Hello World!¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.

4. Flash a new precompiled program¶

It is the newest program on the mbed Microcontroller that is run after reset. We can therefore download a new program or overwrite an existing one to update the program that will run.

Open existing Project¶

1. Import the Program to your mbed compiler¶

Select Import As Program
Choose Import Name of your preference
Click on Import

2. Compile the Program¶

In the right panel Program Workspace Select the program you want to compile
Click on Compile in toolbar
If compilation ends successfully, you should see the comment Success! displayed in the Compile Output window available in the bottom and your web browser should download automatically the precompiled binary for the program.

3. Download a (.bin) to the FRDM Platform¶

Save the program binary file to your mbed Microcontroller Disk, just like you would with a normal USB disk. The Status LED will flash as the PC writes the file to the Microcontroller disk.

4. Press the Reset Button¶

When the Reset Button in pressed, the newest program on the mbed Microcontroller Disk will be loaded in to the Microcontroller FLASH memory. The Status LED will flash as this happens.

When the program is has been loaded onto the microcontroller, it will then start it running.

5. Run the Program¶

The Microcontroller is now running the program; flashing LED1 forever! If you reset the Microcontroller, or disconnect and reconnect the power, the program will simply restart.

Supported Seeed Studio Grove extension modules¶

SEEED STUDIO has recently launched a new family called GROVE of compact Connectivity and Sensor modules, much cheaper (starting $2.90) and smaller than Arduino shields.Up to now the Seeed Grove portfolio includes more than 100 extension solutions!!

Several Grove adapters are available for the major MCU platforms of the market like Arduino, Rasbperry-Pi... to extend your MCU/MPU board with up to 16 grove analog or digital modules. To connect the Grove modules to the FRDM-K64F, we are going to use the Grove Shield v2 compatible with Arduino board pinout.

The mbed repository for the Grove modules covers today 37x Modules with Program Examples and Libraries, which should be easily ported (automatically) for the FRDM-K64F.
