Configuration

Please use frdm_k22f ID for board option in “platformio.ini” (Project Configuration File):

[env:frdm_k22f]
platform = freescalekinetis
board = frdm_k22f

You can override default Freescale Kinetis FRDM-K22F settings per build environment using board_*** option, where *** is a JSON object path from board manifest frdm_k22f.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:frdm_k22f]
platform = freescalekinetis
board = frdm_k22f

; change microcontroller
board_build.mcu = mk22fn512vlh12

; change MCU frequency
board_build.f_cpu = 120000000L

Uploading

Freescale Kinetis FRDM-K22F supports the next uploading protocols:

  • cmsis-dap

  • jlink

  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:frdm_k22f]
platform = freescalekinetis
board = frdm_k22f

upload_protocol = mbed

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Freescale Kinetis FRDM-K22F has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Description

Mbed

The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.

Zephyr

The Zephyr Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.
