Don't be scared of ARM, take it as a normal controller

yes ajay that is the best thing about arm.....
a little intro....
u will find arm proccessor in
1) your PC pentium is based on ARM
2) most mobile/gsm modems
3)PDA's
etc....
so you must know that ARM is just a proccessor core....
it is neither a proccessor nor a cotroller.....
it is u can say.... an idea .....

u see.. pentium is an ARM based proccessor
LPC21xx are ARM based controllers....

thus if u have an idea of working on any controller (8051/AVR/PIC etc).. it will do......plus if u have an idea of working on proccessors... (8085/8086/x86)...it will be an added advantage...

but if u are a basic level programmer assume (8051)..
do not worry.....
if u follow my aproach, u'll find ARM easier than 8051

believe me

now lets get started with the tutorials.....
a little googling can get u the pdf...ebook..
lpc-arm-book_srn.pdf
also look for..
user.manual.lpc2131.lpc2132.lpc2134.lpc2136.lpc2138.pdf
u can get it frm
www.nxp.com

the above two books are more than enough for starters.....

i still use them in almost all my developments......
if u cant find them .... i'll some day post them but they are way to big to be posted....
so better download them urself frm the net....

aha... we are moving to next step then

hey abbas, as you have Proteus so you can use that too for simulation purpose

just wanted to remind you of it

ARM has an embedded ICE (In-curcuit Emulator). Its a real time debugger. Most of the ARM compilers make use of it, so there's no need for any seperate simulator as such.
I have worked a lot on ARM7... the same Philips LPC series. I can contribute anything if required.

sure... we want everyone's contribution.

The reason i mentioned Proteus is.. that people who don't think that they can buy/make a development board, if they have Proteus VSM then they can simulate ARM on it, just to get them started.

And almost all ARMs are equipped with JTAG and so boundary scan can be done and you can get all the internal information of registers through JTAG. Which can help them to debug and test your codes.

i never had time to test my board using JTAG.....
but
@abhishek_h if u could provide us the resources to build our own jtag debugger it would be of gr8 help

as for as the software is considered we can use OCD debugger which u can find in the WinArm package

but i think before we get the board ready , we can use Keil Uvisioin3 for simulating peripherals of the chip...
download demo frm ..

i tried JTAG on PowerPC but not on ARM coz never worked personally on ARM. I used special software that time.. its called single step for PowerPC.

Shyam, after we finish our discussion on ARM board, we will create a new topic for ARM instruction set discussion...

if you have more idea please share..

as i said there are open source software to go by ARM
ex. OCD debugger....
but i feel for starters we should use keil demo version
there we can also simulate the peipherals.......

then while working directly on board we will use
WinArm or cygwin Arm-elf as decided before

as per ideas once we r thru the basic ARM programmes.....
we should try RTOS on to it......
they are easy to implement and interesting....
mean time it would be gr8 if someone starts a new category on
OS fundamentals...
watsay??
