Embedded Artists' LPC2148 Education Board lets you get
up-and-running quickly with NXP's ARM7TDMI LPC21xx microcontroller series in general and with LPC2148 in particular.
The board contains many interesting and useful experiments. The experiments can be further expanded via the expansion connector.
There exist a lot of expansion boards, and new boards are continuously added.
The board can be used for education purposes as well as for experiment and prototype projects.
This is the second revision of this education board. There is a newer revision of this board.
This board is on sale in bundles with expansion boards.

In order to ease the experiments and development of application programs Embedded Artists'
Education 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.
-
Analog to Digital Converter - Demonstrates how to convert the analog inputs into digital values (for processors with built-in ADC).
-
Code Protection - Demonstrates how to enable the code protection functionality (for processors with built-in code protection functionality).
-
In-Application Programming - Demonstrates how to invoke the IAP functionality from an application program (to program the internal FLASH memory).
-
UART - Demonstrates how to use the UART in an irq and a polled implementation (i.e., with or without using interrupts).
Includes a general print number function.
-
Polled I2C - Demonstrates how to use the I2C as a master in polled mode (i.e., without
interrupts). Reading and writing to an i2c-eeprom is used as sample application.
-
SPI - Demonstrates how to use the SPI as a master in both a polled and interrupt
implementation.
-
SWI - Demonstrates how to use SWI interrupt (software interrupts) and how to
create a customer SWI handler.
-
FIQ Handler - Demonstrates how to create a customer FIQ handler.
-
IRQ Handler in SYS Mode - Demonstrates how to create an IRQ handler that execute interrupt handlers in SYSTEM mode, instead of IRQ mode.
-
PWM Examples - Demonstrates how to vary the frequency of a PWM signal and how to vary the
duty cycle of a PWM signal.
-
Timer Interrupt - Demonstrates how to use a timer (in interrupt mode) as system time counter
and how to register timer callback functions.
-
Timer Delay - Demonstrates how a timer can be used to implement exact (polled and irq)
delays.
-
Power Save Mode - Demonstrates how the idle mode can be used to save power.
-
Power Down Mode - Demonstrates how the power down mode (lowest power mode) can be used to save power.
-
Real-Time Clock - Demonstrates how the real-time clock can be used.
-
Watchdog - Demonstrates how the watchdog can be used.
QuickStart Build Environment
In order to be able to build the sample applications (and your own applications) the Education Boards
are delivered with Embedded Artists' build environment. It is based on GCC
v3.4.3 + newlib as the compiler.
Embedded Artists' LPC2148 Education Board is not just another education / prototyping board.
The many unique features and experiments have been developed in cooperation with universities.
