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 ever-growing set of specialist tools for developers to reduce development time, such as pin mux configuration and state configurable time (SCT) design tools.


What's New on LPCXpresso 7.9.0

● Initial support for Windows 10

● Upgraded GNU tools to ARM launchpad GCC 4.9 update 2

● New Generic SPIFI flash driver mechanism, which will autoconfigure based on SPIFI device detected in target system

● Enhanced managed linker script template mechanism

● Support for generating LPC MCU vector table checksums directly in the image, using the startup file and linker script

● "Active Config" is now the default for the indexer

● Fixes to Multicore projects

● Fixed an issue that was preventing MTB trace with LPC82x parts

● Extended CMSIS-DAP JTAG support (for Cortex-M parts) to include Keil ULINK2/ULINK-ME probes

Stadi di sviluppo con LPCXpresso:



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 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.



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.



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).



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.



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.



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.



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.
