The FRDM-K82F is a low cost development platform for Kinetis® K80, K81, and K82 MCUs.

Overview¶

The FRDM-K82F has been designed by NXP in collaboration with Mbed for prototyping all sorts of devices, especially those requiring the size and price point offered by Cortex-M4.The board is well sized for low-power applications, thanks to its power efficient Kinetis K82 MCU featuring an ARM® Cortex®-M4 core running up to 150MHz and embedding 256KB Flash, 256KB RAM. Features on FRDM-K82F include but not limited to dual-role USB interface, QuadSPI memory and headers for use with Bluetooth® and 2.4 GHz radio add-on modules.The Kinetis K82 MCU family remains fully software, hardware and development tool compatibility with other 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 K82 signal connections with the board components (RGB LED, Motion Sensor) and extension connectors (QuadSPI Flash, Camera Expansion Board, 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 K82 signals

• Outer row pins deliver right signals to meet Arduino R3 standard
• Inner row is connected to up to 32 additional Kinetis K82 pins
  

Important Notes

Please note that on this MCU in SPI Slave mode pins labeled MOSI behave as Slave Output and pins labeled MISO behave as Slave Input. The terms MOSI (Master Out Slave In) and MISO (Master In Slave Out) only apply to Master mode.

The FRDM-K82F 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¶

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:

Windows

See Windows-serial-configuration for full details about setting up Windows for serial communication with your Mbed Microcontroller

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:

Firmware Update¶

FirmwareUpdate

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

For FRDM-K82F, at the following link, choose CMSIS-DAP firmware that is compatible with OpenSDA v2.1 bootloader.

Quick Summary: hold down the reset button, plug in the usb cable to the OpenSDA usb connection, copy the new interface firmware to the enumerated drive, done!

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 recognize the Mbed Microcontroller as a standard USB drive.

Mac Os Download

Flash a project binary¶

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

Download the appropriate 'Hello World!' binary:

• NXP FRDM-K82F: HelloWorld_K82F.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

[Repository '/teams/mbed-os-examples/code/mbed-os-example-blinky/' not found]

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.

Is this service legitimate?

Mac Os Catalina

Safari and Chrome, on my MBP 'late 2011', had been compromised with malware that made 'We Know' the default home page. That problem has been resolved. Being extra cautious, I thought I would ask the pros in this community for advice. Thanks for any and all input.
