CH PTER 2: SETTING UP THE LPC-P11C24 BO RD
2. Introduction to the chapter
This section helps you set up the LPC-P11C 4 development board for the first time. Please consider
first the electrostatic warning to avoid damaging the board, then discover the hardware and software
required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior is
detailed.
2.1 Electrostatic warning
LPC-P11C 4 is shipped in a protective anti-static package. The board must not be exposed to high
electrostatic potentials. A grounding strap or similar protective device should be worn when
handling the board. Avoid touching the component pins or any other metallic element.
2.2 Requirements
In order to set up the LPC-P11C 4 optimally, the following items are required:
- 7V to 9V source of power with 1A maximum amperage.
- Personal Computer with RS 3 port
- RS 3 -RS 3 cable
- TRACE/SWD interface programmer for custom code
Code can be loaded via the RS 3 -RS 3 interface and the bootloader, however it is highly
recommended to have a SWD/TRACE programmer at your disposal.
Note that OpenOCD OLIMEX programmers + SWD adapter at the moment of writing are
supported only in Rowleys Crossworks for ARM.

OLIMEX© 01 LPC-P11C 4 user's manual
2.3 Powering the board
The board is powered via the PWR jack by 7 to 9 volts (preferably closer to the upper limit if you
use all peripherals and GPIOs).
When powered by 9V the current measured is around 40mA. The red, green and yellow leds (PWR
LED, LED1 and LED ) turn on.
2.4 Prebuilt software and bootloader
The prebuilt software is a bootloader and a simple LEDs and buttons test. When you power the
board initially all LEDs will be on. If you press and hold the B1 button LED should start blinking.
If you press and hold WAKE_UP button LED1 should start blinking. Upon releasing the buttons the
LEDs should return to their initial “always on” state.
In order to connect with the bootloader you should close PIO1_RS and RST_E jumpers. You will
also need RS 3 cable and RS 3 computer port. After that you can use NXP's FlashMagic
software to check if the board is connected successfully. You can also load binary files via the
RS 3 using the FlashMagic.

6.3 Proto area pads
The proto area allows easier and safer analyzing of signals on the board and also provides easier
access to free processor pins. In the table below the pads are listed with their corresponding
processor pins. When a name of signal is available and written before the processor pin this means
the pad is used for the peripheral of the board and provides debug interface. If you wish to use such
a pad as GPIO probably you would have to disable some of peripherals on the board.
The pad names are written on the board and the names are above the corresponding pads.
