architecture? Why not?
Free RTOS supports ARM7 architecture (including Philips/NXP LPC series).
It's just a matter of different peripherals and memory. Then you need to
configure this i.e. port to your hardware.

I think there is port for LPC2468 on FreeRTOS. However check on the same.

HI ,
Those are great suggestions friends. well thanks for telling me
about LPC2387 doesn't have USB host. I was told by LPC support that it
has
USB host. Anyways I will go for LPC2388.
Yes definitly I will review my schematic from expert before building
up the board. Also I will start s/w by small and simple modules.
Would you suggest me to go for "Free RTOS" which will make PS2/USB
keyboard and Ethernet stack implementation more simple? But I heard "Free
RTOS" does not support LPC23xx architecture?
Regards,
Vihang

LPC2388 also supports USB host.
It has the same type of package as LPC2387 but 144 pins instead of 100.

Hi,
LPC2387 doesn't support USB host. It only supports USB device
functionality.
Look for 2468. This has almost all interfaces.

Ravi

Hello, Vihang.
The first step you need to do is to get a development board. Optionally you can
build it yourself or develop in target system provided you considering some
issues (programming). You might want to discuss the schematics with someone with
experience before building it.
When you have the development board and programming environment start with
simple programs, e.g. first only serial port, then add LCD. USB and Ethernet are
not so simple.

Hi All,
I would like to introduce myself. I am Vihang from India. I
have been working in field of embedded system since last three years.
I have worked on 8/16bit microcontrollers from ATMEL/PIC. Now first
time I am trying my hand on ARM(LPC2387) and I am very excited about
it.
I am going to develop (H/W + S/W) system with following things.
Hardware Requirements:
1. LCD display with 4-6 rows by 16-20 characters.
2. USB host
3. serial port
4. alpha numeric compact keypad (PS2)
5. External memory chip SPI interface- Initial 4MB expandable.
6. Ethernet.
Before I start development I need to know the current resouces
available for LPC2387.
1. Please guide me towards sample codes available for 2387.
2. Are there any ref. hardware design available or hardware design
guideline available.
3. I am bit confused would development be simpler if I go for "free
RTOS". I guess free RTOS doesn't support LPC2387? can any one tell me
how it can be possible to use free RTOS with 2387.
For s/w tools I am thinking of IAR.
