LPCXpresso11U68

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 lpc11u68 ID for board option in “platformio.ini” (Project Configuration File):

[env:lpc11u68]
platform = nxplpc
board = lpc11u68

You can override default LPCXpresso11U68 settings per build environment using board_*** option, where *** is a JSON object path from board manifest lpc11u68.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:lpc11u68]
platform = nxplpc
board = lpc11u68

; change microcontroller
board_build.mcu = lpc11u68

; change MCU frequency
board_build.f_cpu = 50000000L

Uploading

LPCXpresso11U68 supports the next uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:lpc11u68]
platform = nxplpc
board = lpc11u68

upload_protocol = mbed

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).

LPCXpresso11U68 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
