Hi people,

Im looking for a place good on the net to find LPC2138 tutorials.

If someone know where can i find this and want to share with me, please, im
really need it.

Thanks a lot. Start a New Thread

If you Google for 'lpc2138 blinking led' one of the responses is:
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/#lpc_uart_irq

There is an LPC2106 interrupt driven USART example that will very likely run on an lpc2138 IF you create a new linker file with the proper memory layout. Copy LPC2106-ROM.ld to LPC2138-ROM.ld and make the memory layout mods. Just the ROM and RAM sizes in the MEMORY { } section.

Then change the Makefile such that SUBMDL=LPC2138 and you should be good to go with the GCC toolchain (WinARM, GNUARM, YAGARTO or even Rowley Crossworks with a little effort).

For the blinking LED portion, you may need to change the IO pin. See config.h

The is no learning curve to ARM. It is more like a cliff, right straight up!

Could you ask a more vague question ?

Ok, try this one:
http://dreamislife.com/arm/

If you really need help with something specific, ask here.

If you are not sure what your doing,
Write an outline of all the things your program/hardware needs to do,
(that's called a design spec).

Mapping the features of the LPC2138 to your design spec should help you understand if the 2139 will do what you want to do.

Writing some code on a PC in (say Visual C or Pascal) will help you understand if your ideas can be done at all. ( that's called modeling)

Once you understand what it is your are trying to do, geting it into a micro will be lots easier.

Thank to all :)

I'm trying to build a caliper to get back the amount of turns of a wheel,
something like the speedometer of a car.

I'm good at C + + with the Borland compiler, but, speaking of
microcontrollers, I still have to learn almost everything about them.

Thanks for the tips.

The ARM processor is not usually recommended as a 'first' microcontroller. However...

The definitive tutorial on LPC2106 and LPC2148 is James Lynch's excellent work. It's sometimes hard to find but here is one link:

http://gnuarm.alexthegeek.com/

The LPC2138 is a subset of the LPC2148.

If you are using Windows, I would recommended either of two toolchains rather than installing the bits and pieces from the tutorial: The evaluation version of Rowley Crossworks. For personal use there is a very discounted license fee. I also like YAGARTO which is free.

If you are using Linux, again consider Crossworks or GNUARM. You will probably want to build GNUARM from source and everything starts here:

http://www.gnuarm.org/support.html

Grab the build instructions from this page and then select Files to get the GCC 4.3 toolchain source files.
