The LPCXpresso1769 board with CMSIS-DAP containing NXP's ARM Cortex-M3 microcontroller has been designed to make it as easy as possible to get started with Cortex-M3


  • The debug interface is CMSIS-DAP compatible, meaning that it is supported by many development environments, including (but not limited to) MCUXpresso IDE, uVision from Keil/Arm, Embedded Workbench from IAR, etc.
  • The CMSIS-DAP debugger can be disabled with a jumper, allowing an external debugger to be connected (via a standard 10 pos Cortex debug connector)
  • The debug side can be removed in a simpler way than before (snap/break off), but note that it is not possible to connect the two parts again. After breaking off the debug side, we recommend using LPC-Link2 as the debug solution
  • The pcb is a 4-layer design with better grounding and power supply layout, making the board better suited for integration


Recommended Book

Embedded Artists recommends Richard Barry’s book Using the FreeRTOS Real Time Kernel – a Practical Guide, which includes sixteen examples written specifically for the LPC17xx Cortex M3. This is a concise, step by step, ‘hands on’ guide that describes both general multitasking concepts and FreeRTOS specifics. The book is purchased here.
