Developing on the LPC2478

Started by ostehaps01 August 8, 2008
Hi

I'm about to start develop a new system using the brand new LPC2478
(LPC2468 with a LCD controller)

I have a dev board from Embedded Artist

So before I use $$$ on development tool, j-tag etc. I just whant to ask
some Q here.

My needs are as following:

- Good supply of samples for the interfaces (USB Host, Ethernet, UART,
SPI, LCD etc) Prefered is that the development tool comes with rich
collection of samples
- Good support for debugger/compiler
- A good and stable debugger
- Some sort of RTOS ?
- The application doesnt has to be real realtime and the tasks it
schould performe isnt very complex.
Something like showing data and progress, setup stuff and to some
communication with the outside world.
- There is no problem using 6000$ on a commerciel compiler/debugger if
that makes my life easier :-)
- Fast and easy install and usage of development tool. I guess a
Eclipse, GCC compiler takes time to setup and to learn?

Is Keil a ok developmet tool based on the the above needs?
I know there are others like IAR, CrossWorks, HItex etc.

If I select Keil, I have to buy the ULINK2 J-tag? Is that a bad thing?
Is there better J-tags out there?

Hope this is enough info

Hi Thomas,

Keil is more than just an OK development tool, Keil is part of ARM but
fortunately kept most of the good things that it used to be when
independent (better support more microcontroller oriented). IAR and
Keil are overall kind of close, from my experience, Keil is easier to
start with, IAR let's you have a little more control if you want to
embed the tools into a given environment.
It is not a bad thing to buy ULINK2 but you could also use Segger's
JLINK, that is also supported by Keil tools.

Either tool chain (and Rowley's Crossworks as well) will save you some
time over a GNU setup and it will also generate overall smaller code
because the libraries are more optimized.

I think that free examples coming with Keil are more complete than
those coming with IAR, however, if you buy the IAR PowerPAC, that will
provide more Operating system features than Keil's Rea;-Time Library.

Hope that help, Bob
Hi Bob

Yes, thanks for the info... I makes my desision easyer :-)
What I basiclly needs is USB Host support, FAT filesystem, TCP/IP and
som USB Hhost bootloader.
I think I will use the products from HCC Embedded for the USB parts :-

The only one I know of at present is the Embedded Artists LPC2478-OEM
board - you'd have to make your own LCD adapter board to go from their
0.1" header.

It comes with linux on but you can erase the linux and write your own
code with Keil, EA provide samples.
