For better contrast it is possible to supply the base board via USB connector P1 and the
LPCXpresso via a second USB cable connected to the computer.
2.2 LPCXpresso
LPCXpresso is a low-cost development platform available from NXP. The software
consists of an enhanced, Eclipse-based IDE, a GNU C compiler, linker, libraries, and an
enhanced GDB debugger. The hardware consists of the LPCXpresso development board
which has an LPC-Link debug interface and an NXP LPC ARM-based microcontroller
target. LPCXpresso is an end-to-end solution enabling embedded engineers to develop
their applications from initial evaluation to final production.
The LPCXpresso IDE, is based on the popular Eclipse development platform and
includes several LPC-specific enhancements. It is an industry-standard GNU tool chain
with an optimized C library that gives engineers all the tools necessary to develop high-
quality software solutions quickly and cost-effectively. The C programming environment
includes professional-level features. There is syntax coloring, source formatting, function
folding, on- and offline help, and extensive project management automation.
The LPCXpresso target board, jointly developed by NXP, Code Red Technologies, and
Embedded Artists, includes an integrated JTAG debugger (LPC-Link), so there is no
need for a separate JTAG debug probe. The target portion of the board can connect to
expansion boards to provide a greater variety of interfaces, and I/O devices. The on-
board LPC-Link debugger provides a high-speed USB to JTAG/SWD interface to the IDE
and it can be connected to other debug targets such as a customer prototype. Users can
also use the LPCXpresso IDE with the Red Probe JTAG adapter from Code Red
Technologies.
Refer to the “Getting started with NXP LPCXpresso”, listed in the references, for more
information.
The board included with the base board is OM13035 which contains the LPC1115 MCU.
2.3 Switches
Three switches are present on the board, SW1, SW2 and SW3. At the time of writing this
user manual, functionality was not implemented in software yet.
2.4 Jumpers
The board contains a number of jumpers. Below they are listed, along with their
functionality.
•
VBAT: This jumper connects the two AA batteries to the subsequent boost
converter. Remove if the board will be stocked with the batteries inserted.
•
J1: This jumper connects the V
LCD
pin of the LCD drivers to the voltage VLCD_EXT
which is generated on the base board if supply option 3 is used. However, if also
the internal voltage generator is enabled, this can cause damage to the LCD
driver. If the internal voltage generator is used, jumper J1 should be removed.
•
JP3, JP4, JP5, JP6: These jumpers need only be placed when the SPI interface is
used, which is only possible if PCA8537BH is mounted on the board. In all other
