NXP LPC11U34¶

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 lpc11u34_421 ID for board option in “platformio.ini” (Project Configuration File):

[env:lpc11u34_421]
platform = nxplpc
board = lpc11u34_421

You can override default NXP LPC11U34 settings per build environment using board_*** option, where *** is a JSON object path from board manifest lpc11u34_421.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:lpc11u34_421]
platform = nxplpc
board = lpc11u34_421

; change microcontroller
board_build.mcu = lpc11u34

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading¶

NXP LPC11U34 supports the following uploading protocols:

• blackmagic

• jlink

• mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:lpc11u34_421]
platform = nxplpc
board = lpc11u34_421

upload_protocol = mbed

Debugging¶

Debugging - “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 LPC11U34 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.
