INTRODUCTION:
LPC-P2919
board is easy to use development board with LPC2919 - ARM9
microcontroller with CAN and LIN produced by NXP Semiconductors.
With LPC-P2919 you can explore the features of LPC29XX family on budged, the
board has everything necessary to build simple applications: reset and oscillator
circuits, JTAG port for programming and debugging, CAN, LIN, RS232, SD/MMC,
LCD, three status LEDs and two user buttons.
There are plenty of GPIOs on extension headers where you can connect your
additional circuits.
BOARD FEATURES:
-
CPU: LPC2919FBD144 32 bit combine an ARM968E-S CPU core with two
integrated TCM blocks operating at frequencies of 80 MHz, CAN and LIN, 48
kB SRAM, 768 kB flash memory, external memory interface, two 10-bit ADCs,
and multiple serial and parallel interfaces in a single chip.
JTAG connector with ARM 2x10 pin layout for programming/debugging with
ARM-JTAG, ARM-USB-OCD, ARM-USB-TINY

ELECTROSTATIC WARNING:
The LPC-P2919 board is shipped in protective anti-static packaging. The board must
not be subject to high electrostatic potentials. General practice for working with
static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS:
Cables:
The cable you will need depends on the programmer/debugger you use. If
you use
ARM-USB-OCD,
you will need RS232 cable and 1.8 meter USB A-B cable
and if you use
ARM-USB-TINY,
you will need 1.8 meter USB A-B cable.
Hardware:
Programmer/Debugger – one of the Olimex ARM Programmers: ARM-
USB-OCD, ARM-USB-TINY.
Software:
ARM C compiler and JTAG programmer, the possible options are:
-
open source platform: GNU C compiler + OpenOCD and Eclipse
