LPCXpresso802 NXP Semiconductors User Manual 1. Introduction The LPCXpresso family of boards provides a powerful and flexible development system for NXP's Cortex-M MCUs. They can be used with a range of development tools, including the MCUXpresso IDE toolchain. The LPCXpresso802 board is developed by NXP to enable evaluation of and prototyping with the LPC802 MCU. Figure 1 shows the LPCXpresso802 Board. Fig 1.

Insert See schematic. a jumper either between the center and left pin for 3.3V or between center and right pin for 1.8V operation. Note that a jumper must always be installed for the LPC802 to operate. JP2 Voltage selection for LPC802 ADC reference. Insert a jumper either between the center and left pin for 3.
LPCXpresso802 NXP Semiconductors User Manual 3. Getting Started The firmware for the on-board debug probe and Windows 7/8 driver for the virtual com (VCOM) port are available from http://nxp.com/demoboard/OM40000 under the Software and Tools tab (look under “Software” download types). If using Window 7 or 8, you will need to install the VCOM driver by running the installer program before attempting to use the board.

Select the debug probe that appears for your board, then click OK. Note that the IDE will remember your selection for the next time you debug this project, so will not prompt for this again, unless it cannot find the board. 8. The code will execute to main. Press F8 to resume and run the program.
LPCXpresso802 NXP Semiconductors User Manual The CMSIS, DISK and COMM LEDs are connected to the LPC11U35 device. The behavior of the LEDs will vary depending on firmware used, typically the CMSIS LED will blink when debug communication is occurring, and the COMM LED will blink when data is being transferred over the VCOMM port. 4.1 Using an external debug probe An external debug probe that supports ARM’s SWD interface, such as a SEGGER J-Link or PE Micro probe, can be used with the LPCXpresso802 board.
