NXP LPCXpresso55S69

Hardware

Platform NXP LPC: The NXP LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors. The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals.

Configuration

Please use lpcxpresso55s69 ID for board option in “platformio.ini” (Project Configuration File):

[env:lpcxpresso55s69]
platform = nxplpc
board = lpcxpresso55s69

You can override default NXP LPCXpresso55S69 settings per build environment using board_*** option, where *** is a JSON object path from board manifest lpcxpresso55s69.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:lpcxpresso55s69]
platform = nxplpc
board = lpcxpresso55s69

; change microcontroller
board_build.mcu = lpc55s69

; change MCU frequency
board_build.f_cpu = 150000000L

Uploading

NXP LPCXpresso55S69 supports the next uploading protocols:

  • jlink
  • mbed

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:lpcxpresso55s69]
platform = nxplpc
board = lpcxpresso55s69

upload_protocol = jlink

Debugging

Debugging - “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).

NXP LPCXpresso55S69 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
J-LINK Yes Yes
