LPC2101 development kit, which one? |
|
|
Hello Folks,
The Philips ARM series had been out of my price range but the LPC2101
finally seems to be in reach, meaning under $2 in quantity. Now if one
wants to try it out which kit would work? I'd have no problem if it was
for another one of the ARM chips as they seem to be quite compatible.
The only kit for the lower number parts I found at Digikey was the
KS2106 LPC210x Kickstart kit. It is listed to be for the LPC2104 through
2106. Unfortunately there is no data sheet on it and the IAR site
doesn't find it. What I'd need for kicking the tires would be the IAR
suite or something similar, a small experimental board (which seems to
be in that kit) and a USB programmer (no word about that one).
Does anyone use this KS2106 kit? Is it the complete deal to get started?
Regards, Joerg

Given that I know (from the msp430 list) that you want the ADC,
you could go for the LPC-H2138 from www.olimex.com. A lot more
ROM and RAM than 2101, but it has the ADC, and it's always good
to have extra headroom when developing. Should be under $100,
shipped to you with JTAG adapter. |

The new Keil board might be better. The LPC2104/5/6 are the oldest LPC2000
chips, and the LPC2101/2/3 are the newest, with quite some differences.

Joerg,
right now the Keil Board as mentioned is definitely the best choice
(the only one on top of that ;-).
You can order one here: www.lpctools.com for $99.
LPCtools ships usually next day from CA, so you might have a board in 2
days.
p.s. you do NOT want to use the LPC2104/5/6 board because those devices
do not have an ADC nor a 32 kHz Real-Time Clock nor Counter inputs nor
Fast I/Os nor a buffered SPI....
As Karl mentioned, the 2101/2/3 are the newest Philips ARM chips, the
2104/5/6 the oldest.

The 8051 (and PICs) are like roaches; they'll be around for a very
long time. But I think, from a designer's pov, the ARM is a very nice
complement to 8-bit and 8/16 micros such as the MSP430. At 0.18u the
new Cortex M3 (Thumb mode only) will be only 0.35mm^2, they say. The
existing ARM7 core units are a bit slow at some math operations, and
system cost is going to be a bit higher than 8-bit micros in some
cases (low output drive and voltage, multiple regulators etc.) but
they are already pretty much in a different class, and there's an
upward migration path.
Also, like the 8051, they're on their way to having a large number of
manufacturers and a large number of variants on the market. So, I'm
bullish on them.

The newer LPC dev boards are a bit strange in this respect. They use a
USB link only to suck power, it doesn't connect to anywhere but the
regulator input. Programming is either via JTAG or RS232.

Hmm, slow on math? That would be a concern since I have to run lots of
filters. Multiplication is the reason why the MSP430 won't fly since
only the luxury editions (lots of $$) come with a HW multiplier.
Yes, the dual supply on the ARM is a pain. If I use them it'll probably
be one switcher and a linear regulator, or two switchers. Whatever is
more economical. One switcher would be needed anyway no matter which uC
since it's battery operated and anything other than a couple AA cells is
not really practical.

That means longevity, to some extent. This is why I had never used
anything but 8051 in the past. Stuff needed to be able to remain in
production for at least a decade.

Working directly with the 2101 would be best indeed. Any version above
2103 is off limits for most of my projects because of prohibitive cost.
I'll check that out. Keil has no pricing on their web site so one has to
go through the stone age quoting rigamaroo. A bit strange, oh well.

Sparkfun has that one in the US for $65. But you'd need a USB
programmer. Those 'new and improved' laptops are USB only.
The 2101 also has the ADC but it's not in the data sheet (yet?). The
whole section 6.8 where its TOC says the ADC is spec'd was missing from
the data sheet on the Philips server. Really strange.

Yes, if I had RS232. But the PCs around here are mostly USB only. Maybe
some converter box would work. But I remember that it didn't with the
MSP430 programmer so I had to get the USB version for that one. I just
want to avoid having a gazillion of these boxes flying around, like one
for every uC family.

Apparently you can do in-circuit debugging through the JTAG port, with
real breakpoints, and you can single-step, examine register contents
and so on, which I suppose is worth something-- not quite a real ICE,
but on the cheap.
In the past, I've found simulation of the tricky stuff preferable--
the "window" through with you see the micro is bigger and more
responsive, and ICD probably grabs some resources, but when you need
hardware debugging you probably *really* need it bad. Fortunately,
that's seldom.
Keil has integrated stuff like code coverage analysis into the
debugger interface, so maybe it's not as primitive as some I've used.
