I am using lpc2103.till now I am using IR sensor to send motion then send the message through pc connect via RS-232 to ARM.

I want to interface a camera with the board but lpc2103 memory is less.
Could somebody please help in how to interface off chip flash memory then load OS kenel into flash.Is this a good idea by the way.

Please help me I am just a begineer.

Any help would be really appreciated

Thanks

You can use I2C interface on 2103 to access flash.

The 2103 has no external bus.

But you should be able to read the manual ?

What 'final year' is it?
Why are all of the students asking for help with the finals projects?
(Rhetorical question).

You did not specify what the electrical interface of the IR sensor or the
flash technology or what type of O/S.
It would also be useful to know what type of data throughput performance you
expect.

In real-world engineering, concise details in documentation and
communication with other people is ESSENTIAL.
The same skills and consideration goes with this group so you do not waste
everyone's time. Hopefully your school is not just about technical
expertise, but also -human- language interactions.

One thing I will take a 'wild guess' in respect to the flash: I am having
a lot of success using Serial (SIO) Flash devices in a SO-8 package. They
are super-easy to interface with their low-pin count, have high-capacities,
are easy to program, erase & read and cost under $2 US-dollars in
single-unit quantities. I have been using a part from Numonyx that is 2
Megabytes.

Hi,
I am sorry if I missed out so many required details

I am doing my final year of engineering 4th year last sem BTech ECE.

Progress of the project

Till now I have done programs like timer and uart interrupt.
And I am trying to configure IR sensor as an external pin(as GPIO pin has this option).I am trying to use a very simple IR sensor.This sensor has to be given some input voltage 5V(DC) on sensing motion it outputs voltage 5V on detection.And then I thought of using ADC present in LPC2103.

I havent got IR sensor.It will reach within probably 2 days.
Here is the link to IR sensor details
http://robokits.co.in/shop/index.php?main_page=product_info&products_id#4

I thought of loading free RTOS or embedded linux if possible.
I have referred the manual for programming earlier.

But
Interfacing Flash memory means dealing with addressing thats where I am doubtful....

Frankly telling I dont mind the performance so much that is not the criteria but simplicity and how fast it can be done.

If any details I ahve missed out please let me know

thanks for helping

Don't count on running Linux on the LPC2103.

Please could you suggest other method to do the same.
Thanks

Hey, but maybe LUnix :-)

NetBSD, or better yet, FreeBSD, since it is really free.
