Freescale Kinetis FRDM-K22F¶

Hardware¶

Platform Freescale Kinetis: Freescale Kinetis Microcontrollers is family of multiple hardware- and software-compatible ARM Cortex-M0+, Cortex-M4 and Cortex-M7-based MCU series. Kinetis MCUs offer exceptional low-power performance, scalability and feature integration.

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 following 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¶

Debugging - “1-click” solution for debugging with a zero configuration.

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.
