Lpc2000

I've just received 10 PCBs for Eduardo's LPC-M216 DIL module from
PCB-Pool.

I've uploaded a pic of the front and back to the Files area: module.jpg

PCB-Pool's protoype service doesn't include silk-screen. The boards
appear to be up to their usual high standard of quality.

I'll be sending one to Eduardo and only want a couple for myself. If
anyone is interested in buying one or two of the remainder, please get
in touch. Price will be 16 Euros each, including air-mail postage.

I'll be putting one together when I get the parts I need (regulator
and 0603 Rs and Cs).

Sweet, I'm looking at making something similar myself. Are those extra 
holes I see for a JTAG interface header in the middle of the thing?

Ok, ok, I could follow the traces from the image and look up the pinout 
of the chip, but that would be *effort* ;-)

For mine, I plan to bring out just the serial link, reset, and the line 
that is used to invoke the ROM bootloader - no need for complex 
debuggery, since I'll run FORTH on it and debug via the serial link anyway.

Tempatation, temptation... you're in the UK, aren't you? What's that in 
pounds with mere first class postage? :-)

Yes, that's right.

I was designing something like it as well, until Eduardo did this. I have
reservations about his decoupling capacitors, the one for the I/O supply is
a long way
from the chip. I'd have put them on the underside, as close to the chip as
possible.

Have a look at his docs for the schematic, etc.

I'll design a simple home-made PCB to take the module and a 3.3 V regulator,
plus an LED,
RS-232 transceiver, etc.

I was thinking of porting a Forth to it, as well. 8-)

My invoice from PCB-Pool was in Euros and I worked the price out from that.
Say 10 pounds. PayPal would be quickest.

What flavour of Forth are you planning to port to the chip? I'm 
interested in playing with that myself once my devel modules arrive from 
Olimex.

BTW did you use to be called Alaric B. Williams and run rfc.net? If so I 
think we met a few years ago at an exhibition in London.

Can the lpc2100 program it's own Flash memory without invoking the
bootloader ? Does it have those intructions like the avr mega series ? The
would be quite nice to run a FORTH system..

I'm planning on making a stab at gForth, although I haven't looked too 
deeply into feasability yet! But where gcc can go, gforth can generally 
follow, if not with all the platform-specific speed tricks.

Bwah! Are you one of the many former Alexes of (void)? Who Lee Maguire 
and I did meet? For indeed, I used to be called Alaric B. Williams, and 
I run RFC.net (which is back up after a long 'rest' due to 'networking 
problems' that turned out to be due to the ISP not configuring their 
switch right).

gForth is nice but I think pForth is worth considering too for ease of 
portability and compactness:
http://www.softsynth.com/pforth/

Also worth a look is Andrew Mileski's SAForth written in GNU format 
assembly for the StrongARM 110- perhaps a bit more work to port but 
probably faster and definitely smaller than a C-based Forth:
http://netwinder.oregonstate.edu/devteam/andrewm/forth/strongarm/saforth-0.12.tar.gz

I should point out that I'm in no way a Forth expert.

That's right :)

Yes, look at page 193 of the User Manual. It's called 'In-Application
Programming' or IAP.

I'll take a look, thanks!

Mmmm, that might be good... more effort though. Perhaps for version 2.

Either way, when I'm done I'll post [a link to] my port here.

Hi Alaric!
I'm also interested running Forth on it. Do you know www.tinyboot.com and
www.cynetix.de/avise (there is a english link) ?
What Forth do you plan on it? I need a portation to ARM.

Henry

I've put it on my NetWinder so you can try it out by telnetting to 
alexholden.net port 4242 (for a limited time only).

Another question: has anyone done any work on simulating an LPC210x in 
SID? It seems like it could be a nice way to develop software for the 
processor without using real hardware. http://sources.redhat.com/sid/

Woot! Output seems odd - can't seem to *see* anything. "1 1 + ." just 
says "OK" :-)

Hmmm, it already has ARM7T processor support. Handy. Lots of finnicky 
little peripherals inside the LPC210xes, but since some of them are 
rarely used, you could start by getting a few up and it would already be 
useful for many applications, then work from there as needed.

It seems to be a bug, possibly in doACCEPT, related to the fact that 
telnet sends CRLF at the end of the line instead of just LF. A 
workaround seems to be to press space before enter, ie.
1 1 + . <enter>

It's obviously alpha quality code that seems to have been abandoned back 
in 2000 after a few months work, so I wouldn't be surprised to find that 
it's buggy and incomplete. I exchanged emails with the author on an 
unrelated subject a few days ago though so he's still around to answer 
questions. If you want to try porting pforth or gforth I might have a 
stab at saforth myself (more choice = good right?).

I may put them beneath for mine. I fancy learning surface mount board 
design (already done PTH), so am not particularly fazed by the effort of 
doing it myself in order to get the experience :-)

In fact, I'm wondering about putting the LPC itself underneath with the 
crystal, caps, and regulators on top, since it has such fine traces 
around it that I can imagine accidentally scraping in my clumsy haste 
and it's not a very thick chip. Then I can maybe put the crystal OVER 
the vias connecting straight through to the XTAL lines on the device, 
for the shortest possible traces. Putting the crystal underneath with 
the LPC on top might foul some DIL sockets, IMHO.

Mmmm, successful flashing LED = satisfaction :-)

As I said to Alex, I'll publish whatever I manage here. I'm tempted to 
write my own forth in assembler, to be honest, because I'm a bit odd in 
the head. But it'll be open source either way.

I'm evolving some twisted ideas about how to use IAP to interactively 
compile to FLASH, and to store an initial RAM image that gets copied 
into RAM on startup or reset (with initial variable values in). This 
will require a way of stating when allocated space is to be considered 
variable (and put into RAM) or constant (and written into flash when 
it's ready), but I think just some variations on the syntax of CREATE 
ought to do it.

Oh, and I'll need a "SAVE" word to copy the current RAM down into the 
startup image area.

Where've you managed to get LPC chips from in the UK, if you don't mind 
me asking? I'm pursuing a quote from Spoerle in Germany who say they're 
on an 8 week leadtime. These chips ain't widely available yet :-/

I got 10 pcs LPC2106 from Avnet-Silica, for about 10 GBP each. I don't know
what their current stock position is.
