## 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.

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.
