Introduction
Thank you for buying Embedded Artists’ LPCXpresso Base Board, designed for the LPCXpresso Board (target LPC1343 and LPC1114) and the mbed module from NXP’s.
This document is a User’s Guide that describes the LPCXpresso Base Board hardware design. The general focus will be for the LPCXpresso boards but differences for the mbed module will be noted.
ESD and Handling Precaution
Please note that the LPCXpresso Base Board come without any case/box and all components are exposed for finger touches – and therefore extra attention must be paid to ESD (Electro-Static Discharge) precaution.
Make it a habit to always first touch the metal surface of one of the USB or SC/MMC connectors for a few seconds with both hands before touching any other parts of the boards. That way, you will have the same electrical potential as the board and therefore minimize the risk for ESD.
Design and Production Services
Embedded Artists provide design services for custom designs, either completely new or modification to existing boards. Specific peripherals and I/O can be added easily to different designs, for example, communication interfaces, specific analog or digital I/O, and power supplies. Embedded Artists has a broad, and long, experience in designing industrial electronics in general and with NXP’s LPC2xxx microcontroller family in specific. Our competence also includes wireless and wired communication for embedded systems. For example IEEE802.11b/g (WLAN), Bluetooth™, ZigBee™, ISM RF, Ethernet, CAN, RS485, and Fieldbuses.
USB Driver Behavior
Sometimes the USB COM port does not enumerate properly when the board in connected to the PC. This is a known “feature” of the USB driver. If you experience this problem, just unplug the board shortly and then plug in again. A new COM port that can be accessed properly should be created the second time. This problem may occur after every time you start (i.e., power cycle) your PC.
