LPC2xxx diy programmer and how should i start

Started by "ezesolares.listas" June 21, 2008
Hi!

I'm trying to get into the LPC2xxx world but i live in a south
american country... so, i can't buy a fancy development board
and i can't buy an already made programmer..
So, i'm about to buy some components from digikey with a
couple of friends and i was wondering

- best LPC2xxx mcu to start
- another componentes i should buy to make myself a great
development board (where can i find an already made dev
board?)
- best Do it youself LPC21xx programmer..

I was thinking the LPC2124 and the LPC2138.. but i have no
idea what programmer should i use, and well, software also
(winarm sounds good)

Thanks in advance

My design for a JTAG interface is in the Files section (jtag.zip). It works
very well.

You really want to install YAGARTO. Everything you need, including
OpenOCD, is included. Ready to run and free!

If you want to use ISP for programming (as opposed to JTAG), there is
a simple interface here:
http://www.sparkfun.com/commerce/product_info.php?products_idq4
Build something just like it on your development board. The schematic
is given.

The LPC2148 is very useful. Especially when you grab the demo code at
www.jcwren.com/arm. It has a bunch of neat toys like A/D and USB.
For a less complex chip, the LPC2106 is my favorite. It has a ton of
flash and RAM but no A/D or USB.

i would prefer a jtag interface.. but well, i need to know which one.. i was
watching USBProg... looks like a nice all in one programmer.
So, any other jtag interface i should look for?

I've already mentioned mine. It's very cheap, and works with the Rowley
software.

Dear Ezequiel Solares,
I am not an expect in ARM, but I am playing with Embedded Artists Quick Start LPC2148 board.
I do not use any Jtag to program, instead I use the sample program and program it through serial port.
I use the Quick Start board together with the prototype board. I use the LED as indicator for the program flow.

I would check out the Rowley CrossFire Evaluation
Kits.

http://www.rowley.co.uk/crossfire/crossfire_lpc2138.htm

The IDE is one of the best that I've used. The
compiler comes with its own tasking library.
