LPCXpresso IDE
Overview
The LPCXpresso IDE is a comprehensive, highly-integrated
Eclipse-based IDE software development toolchain for NXP LPC
microcontrollers based on Cortex-M, ARM7, and ARM9 cores. It
features the industry-standard GNU toolchain with a proprietary,
optimized C library based on the standard Newlib library, plus
many enhancements to simplify development with NXP LPC
microcontrollers. NXP is continually updating the LPCXpresso IDE
to make sure the latest advances from ARM’s compiler
development team and the Eclipse Foundation are available for
your LPC projects. The LPCXpresso IDE also integrates an evergrowing set of specialist tools for developers to reduce
development time, such as pin mux configuration and state
configurable time (SCT) design tools.

Sviluppo di un progetto
Stadi di sviluppo con LPCXpresso:
36/80
The latest generation of LPCXpresso boards are an evolution of the V2 version, maintaining the Arduino UNO
compatible shield connectors on the board top side, and adding additional rows of expansion connectors
adjacent to them. As with V2 boards, they include an onboard LPC-Link2 based debug probe, compatible with
the LPCXpresso IDE out-of-the-box, and with other toolchains via optional firmware, including ARM CMSISDAP. These boards can also be configured to act as a standalone probe to allowing debugging of an external
board, and the 10-pin debug connector also allows debugging of target MCU via an external probe.
37/80
LPCXpresso V2 boards build upon the original and highly successful V1 design. These boards provide
"Arduino UNO" compatible shield connectors on the board top side, as well as a ‘standard LPCXpresso/mbed’
expansion connector (board bottom side). They also include an onboard LPC-Link2 based debug probe,
compatible with the LPCXpresso IDE out-of-the-box, and with other toolchains via optional firmware, including
ARM CMSIS-DAP. These boards can also be configured to act as a standalone probe to allowing debugging
of an external board, and the 10-pin debug connector also allows debugging of target MCU via an external
probe.
38/80
Designed to provide a flexible hardware platform for low-end LPC MCUs, the LPCXpresso MAX
boards comes pre-programmed for mbed compatibility. They also include an onboard CMSIS-DAP
based debug probe for compatibility with a wide range of toolchains, and can also be used with an
external probe. These boards provide "Arduino UNO" compatible shield connectors on the board top
side, as well as a ‘standard LPCXpresso/mbed’ expansion connector (board bottom side).
39/80
Designed to replace the original LPCXpresso board, this CMSIS-DAP (or CD) version replaces the
original on-board debug probe called "LPC-Link" with a CMSIS-DAP probe implemented using an
LPC11U3x MCU. The board still seamlessly connects the LPCXpresso IDE (version 7.9 onwards
required) to the target MCU via full speed USB. The target includes a small prototyping area and easily
accessible connections for expansion. An RGB LED is fitted as standard, as are reset and ISP buttons
for easier operation. Other features (such as peripheral connectors) are dependent on the variant used.
40/80
Due to the debug probe (MCU) no longer being available, most original LPCXpresso boards featuring
the LPC-Link debug probe are being replaced with LPCXpresso CD, LPCXpresso MAX type boards
(with CMSIS-DAP debug probes). For other MCUs alternative boards are recommended
Since first introduced in 2009, the original LPCXpresso family of boards, along with the
associated LPCXpresso IDE, has reenergised the whole MCU evaluation board market. Each
LPCXpresso board includes an on-board debug probe called "LPC-Link" and a target MCU.
LPC-Link seamlessly connects the LPCXpresso IDE to the target MCU via USB, and can also
be modified to allow debugging of an external board. The target includes a small prototyping
area and easily accessible connections for expansion. An LED is also fitted as standard, with
some board variants having additional fittings such as an RGB LED, potentiometer or USB
device connector.
41/80
LPC-Link 2 is an extensible, stand-alone debug probe that is compatible
out of the box with the LPCXpresso IDE. It can also be configured to
support various development tools and IDEs using a number of different
downloadable firmware images, include CMSIS-DAP and Seggar J-Link.
It can also be used as an evaluation board in its own right for the NXP
LPC4370 triple core MCU.
42/80
LPCXpresso MAX, V2 and V3 boards feature Arduino UNO R3 compatible expansion connectors, so can be
used with a range of third party Arduino shield (check individual LPCXpresso boards for compatibility). V3
boards have extended expansion sites that add several more signals for interfaces such as Ethernet, CAN
and SDIO, along with extra UART, I2C and SPI connectivity.
Current products:
LPC General Purpose Shield (OM13082)
Sensor Shield Board (only available as part of the LPC54102 Sensor Processing/Motion Solution OM13078)

Example Code - LPCOpen
An integral part of the LPCXpresso platform is the driver and example code that we provide =>
LPCOpen. Packages for the various LPCXpresso boards can be downloaded, suitable for use out
of the box with Keil, IAR and our own LPCXpresso IDE.
