LPCXpresso804 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. The LPCXpresso804 board is developed by NXP to enable evaluation of and prototyping with the LPC804 MCU. Figure 1 shows the LPCXpresso804 main board. The board is also supplied with capacitive touch and PLU design prototyping shield boards. Fig 1.

LPCXpresso804 NXP Semiconductors User Manual 3. Getting Started This section describes how the operation of the factory programmed demo program, and how to set up your board for code development with MCUXpresso IDE and/or third party tools. 3.1 Initial setup and pre-programmed demo program The LPCXpresso804 board is pre-programmed with a diagnostic demo program, which tests various features of the board.
LPCXpresso804 NXP Semiconductors User Manual Follow the steps below to build and run a simple example from the LPC804 Code Bundles provided by NXP. 1. Code Bundles for the LPC8xx family are included in the MCUXpresso IDE installation. These can also be downloaded from nxp.com (in case of any updates between IDE releases): http://www.nxp.com/products/software-and-tools/software-development-tools/softwar e-tools/lpc800-code-bundles:LPC800-Code-Bundles. 2. Open a new workspace in the IDE. 3.
LPCXpresso804 NXP Semiconductors User Manual 3.4 Debugger firmware update (optional) The MP board comes pre-programmed with a CMSIS-DAP firmware image; it is not normally necessary to update the debugger firmware image, but this can be done by following the steps below. 1. Hold down the reset button and keep it held down while applying power to the board. Release reset. Using File Explorer (or equivalent on Mac/Linux platforms), look at the available drives on your system.
LPCXpresso804 NXP Semiconductors User Manual 5.1 Arduino UNO Rev 3 expansion connectors The Arduino UNO Rev 3 compatible connectors provided on the LPCXpresso804 board provide I2C, SPI, UART, PWM and analog function connections to shield boards that are available from various 3rd part suppliers, or for customer use. The pin mappings are shown in the tables below. Some connections are shared with other board features, as shown (in addition to being available on breakout headers C6 and CN7.) Table 2.

This header supplies the I2C connections plus 3.3V and ground.
LPCXpresso804 NXP Semiconductors User Manual 7.2 User button The User button (S1) is for general purpose use by LPC804 applications. It is connected to a 10K ohm pullup to 3.3V, and to the LPC804 PIO0_13 pin. It is also shared with the red User LED1. 7.3 User LEDs Three users LEDs are provided on the board, one blue, one green and one red. The anodes of the LEDs are connected together, then through a zero ohm resistor to the 3.3V regulator output (each has its own current limit resistor in-line).
LPCXpresso804 NXP Semiconductors User Manual The PLU shield also includes a test circuit that can be used to implement a simple continuity tester, for experimentation with the LPC804 ADC and DAC (requires some shield board modification.) Several signals from the LPC804 used on the PLU Shield are shared with other functions on the main LPCXpresso804 board. Please review jumper settings on the LPCXpresso804 board carefully before installing the PLU Shield.
