CHAPTER 2: SETTING UP THE LPC-P11C24 BOARD

2. Introduction to the chapter

This section helps you set up the LPC-P11C24 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-P11C24 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-P11C24 optimally, the following items are required:

- 7V to 9V source of power with 1A maximum amperage.

- Personal Computer with RS232 port

- RS232-RS232 cable

- TRACE/SWD interface programmer for custom code

Code can be loaded via the RS232-RS232 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.

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 LED2) 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 LED2 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 RS232 cable and RS232 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 RS232 using the FlashMagic.
