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.

Microcontroller LPC11C24
Frequency 48MHz
Flash 32KB
Vendor NXP


Please use lpc11c24 ID for board option in “platformio.ini” (Project Configuration File):

platform = nxplpc
board = lpc11c24

You can override default NXP LPC11C24 settings per build environment using board_*** option, where *** is a JSON object path from board manifest lpc11c24.json. For example, board_build.mcu, board_build.f_cpu, etc.

platform = nxplpc
board = lpc11c24

; change microcontroller
board_build.mcu = lpc11c24

; change MCU frequency
board_build.f_cpu = 48000000L


NXP LPC11C24 supports the next uploading protocols:

  • blackmagic
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

platform = nxplpc
board = lpc11c24

upload_protocol = mbed


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


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 LPC11C24 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
Black Magic Probe   Yes
