NXP LPCXpresso54114¶

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 lpc54114 ID for board option in “platformio.ini” (Project Configuration File):

[env:lpc54114]
platform = nxplpc
board = lpc54114

You can override default NXP LPCXpresso54114 settings per build environment using board_*** option, where *** is a JSON object path from board manifest lpc54114.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:lpc54114]
platform = nxplpc
board = lpc54114

; change microcontroller
board_build.mcu = lpc54114j256bd64

; change MCU frequency
board_build.f_cpu = 100000000L

Uploading¶

NXP LPCXpresso54114 supports the next uploading protocols:

• cmsis-dap

• jlink

• mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:lpc54114]
platform = nxplpc
board = lpc54114

upload_protocol = mbed

Debugging¶

PIO Unified Debugger - “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).

NXP LPCXpresso54114 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
