Embedded Artists' LPC2478 OEM Board (mounted on the QVGA OEM Base Board with touch panel) lets you get up-and-running quickly with NXP's ARM7TDMI LPC24xx microcontroller series in general and with LPC2478 in particular. The OEM board has SODIMM format and is only 66x48 mm and is perfect for running uClinux with large on-board RAM and FLASH. All processor signals are available on the 200 pos connector for easy expansion.
The board can be used in OEM applications, as well as for education purposes, experiment, and prototype projects.
uClinux Distribution
Embedded Artists provide a uClinux distribution for the board based on Linux 2.6 and using u-Boot 1.1.6 for booting.
The distribution is provided "as-is" and without any support. A Yahoo group exist for the board for sharing experiences.
They do, however, provide a support page packed with information how to get started with uClinux, working with drivers and developing uClinux applications (available after purchase).
A specific frame buffer driver does not exist for the LPC2478 at this moment.
A DVD is included with a complete Linux development environment for uClinux development, based on VMware Player™ technology - you can develop for uClinux on your Windows PC!

In order to ease the development of and experiments with application programs our boards are delivered with a lot of software/sample applications.
- Pre-emptive Real-Time Operating System (RTOS) - the RTOS is delivered as a binary package together with some sample applications that illustrate different functionalities of the RTOS.
Can be used for non-commercial applications.
- SDRAM initialization example.
- Sample applications.
QuickStart Build Environment
In order to be able to build the sample applications (and your own applications) you get access to Embedded Artists' build environment. It is based on GCC + newlib as the compiler.
Embedded Artists' LPC2478 OEM Board is not just another prototyping board. The many unique features and the extensive support package provided gives you a head start before your competitors.
- Get up-and-running quickly
- Start developing/experimenting on day 1
- Embedded Artists's QuickStart Build Environment included (compiler, linker, make, editor, etc.) – based on GCC
- Many sample applications included
- Extensive documentation
- Real-time operating system (RTOS) included
- Board support package (BSP) included
- Simple and automatic program download (ISP)
The LPC2478 OEM Board is very low cost and can be used for prototyping/development as well as for OEM production.
