u-blox C027

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.

Microcontroller LPC1768
Frequency 96MHz
Flash 512KB
RAM 64KB
Vendor u-blox

Configuration

Please use ubloxc027 ID for board option in “platformio.ini” (Project Configuration File):

[env:ubloxc027]
platform = nxplpc
board = ubloxc027

You can override default u-blox C027 settings per build environment using board_*** option, where *** is a JSON object path from board manifest ubloxc027.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:ubloxc027]
platform = nxplpc
board = ubloxc027

; change microcontroller
board_build.mcu = lpc1768

; change MCU frequency
board_build.f_cpu = 96000000L

Uploading

u-blox C027 supports the next uploading protocols:

  • jlink
  • blackmagic
  • cmsis-dap
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:ubloxc027]
platform = nxplpc
board = ubloxc027

upload_protocol = mbed

Debugging

PIO Unified Debugger - “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).

u-blox C027 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
Black Magic Probe    
CMSIS-DAP Yes Yes

Frameworks

Name Description
mbed The mbed framework The mbed SDK has been designed to provide enough hardware abstraction to be intuitive and concise, yet powerful enough to build complex projects. It is built on the low-level ARM CMSIS APIs, allowing you to code down to the metal if needed. In addition to RTOS, USB and Networking libraries, a cookbook of hundreds of reusable peripheral and module libraries have been built on top of the SDK by the mbed Developer Community.
