LPC2148 & RTOS, need suggestions

Started by SohaIb Qammar July 7, 2009
Hi all

I m planning to use LPC2148 development board (MDfly) for my project regarding OBD development.
I have to develop a RTOS for the complete project using microcontroller.

The reason for writing here is to take some helpful and experienced suggestions regarding LPC2148.
Can i develop the RTOS using LPC2148 or more specifically i have to develop an operating system like
SymbianOS using some processor. Can i easily find help for developing RTOS using LPC2148 ? I would
really appreciate ur suggestions and helpful opinions.

Best Regards
SohaIb.

You need to develop an RTOS? Why not use an existing offering? Take a look
at
http://www.jcwren.com/arm/ for some LPC2148 examples.

Sohalb,

What is the time frame that you are looking at? Developing an RTOS is not a
very simple thing to do. As someone rightly suggested; try using the
available free RTOS like FreeRtos, Tnkernel; may be you also wanna have a
look at http://code.google.com/p/blueboard-lpc214x/.

All the best.

Warm regards
Ashwin

Other posters have suggested that it may be easier to use an RTOS that has already been developed and tested. I would go further - don't try to develop your own 'Symbian' unless you have a large department and huge development budget - you *will* fail if you try.

Can i easily find help for developing RTOS using LPC2148 ?

Sure - start with hardware user manuals and assembler language - you will need all that to get the interrupt-handling, synchronization, scheduler/dispatcher and memory-manager working. You will need a good development system with hardware debugger.

Oh, and yes - cancel your vacations.
