Freescale Kinetis FRDM-KL43Z

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.

Microcontroller MKL43Z256VLH4
Frequency 48MHz
Flash 256KB
RAM 32KB
Vendor Freescale

Configuration

Please use frdm_kl43z ID for board option in “platformio.ini” (Project Configuration File):

[env:frdm_kl43z]
platform = freescalekinetis
board = frdm_kl43z

You can override default Freescale Kinetis FRDM-KL43Z settings per build environment using board_*** option, where *** is a JSON object path from board manifest frdm_kl43z.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:frdm_kl43z]
platform = freescalekinetis
board = frdm_kl43z

; change microcontroller
board_build.mcu = mkl43z256vlh4

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Freescale Kinetis FRDM-KL43Z supports the next uploading protocols:

  • cmsis-dap
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:frdm_kl43z]
platform = freescalekinetis
board = frdm_kl43z

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-KL43Z has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools On-board Default
CMSIS-DAP Yes Yes
J-LINK
