(Note: This is not the correct picture of the LPC2148 board, but the board looks very similar)
Embedded Artists' LPC2148 USB QuickStart Board lets you get
up-and-running quickly with NXP's ARM7TDMI LPC2148 microcontroller.
The small form factor board offers many unique features that ease your
development.

| Other |
• 2 Kbit I2C E2PROM for storing non-volatile parameters
• Simple and automatic program download (ISP) via serial channel.
Circuit that automatically controls the bootloader from RS232 channel
• Four layer PCB (FR-4 material) for best noise immunity
• Both UART #0 and #1 connected

In order to ease the development of application programs Embedded Artists'
QuickStart 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 the QuickStart Boards
are delivered with Embedded Artists' build environment. It is based on GCC
v3.4.3 + newlib as the compiler.
Embedded Artists' LPC2148 QuickStart 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 on day 1
-
Development environment included (compiler, linker, make, editor, etc.)
– based on GCC
- Many sample applications included
- Extensive documentation
- Rowleys CrossWorks included (30 day evaluation version)
- IAR Embedded Workbench KickStart Compiler included (32 KByte limited)
- Real-time operating system (RTOS) included
- Board support package (BSP) included
- Minimize design problems by using pre-designed hardware boards
- Simple and automatic program download (ISP)
The LPC2148 QuickStart Board is very low cost and can be used for
prototyping/development as well as for OEM production.
Modifications for OEM production can easily be done for volume customers.
Contact Embedded Artists for further information about design and production services.
You will likely be surprised at our competitive prices!
Bulk boards (10 or 100 board packages) can be delivered without pin rows
soldered for easy integration with original equipment.
