Hi all, I am just wondering what your Favorite programmable microcontroller is
and why? I am trying to find out as much information about different types of
microcontrollers to compare.


Thanks,
Jeremy
 
My favourites are Atmel 89c51RD2, AC2, CC01, CC02 depending on application,
I like
them because they are ISP programmable.

I'm afraid I don't think there is any such thing...

The 'favourite', must change with the application. The PICs, are very
popular for small applications, because there are a large number of variants
with different hardware based round the same 'core', and a lot of 'code
examples' exist, making them popular for hobbyists. However the higher speed
versions can be fussy. Scenix, and the AVR's (Atmel), are probably the
preferred ones for slightly faster applications. Then you have units
for special applications (8051 based USB interfaces for example, and
devices designed for high noise enviroments, such as the automobile
industry).
This is why there are so many types in existence, from different
manufacturers. To work out the 'best', requires generating a list of
hardware features required. This will 'rule out', eighty percent of the
types on the market, and a sensible choice can then be made from the
remainder.

Uh, maybe you should take a short break from writing that next book.

But...

I love my love with a K because the designers understood K.I.S.S.
I love my love with a Y because the Yield is high.
I love my love with a Z because she got legs!

I assume you are talking about 8 bit micros where all the RAM/ROM
is included on chip.

High volume production or home hacking?

Atmel AVR parts are popular. I think their $79 starter kit
(ATSTK500) covers all their AVR parts. They are reasonably
friendly for assembly programming.

If cost is your major concern, PICs have a reputation for
low cost. (I've never purchased large quantities.) They have
a starter kit (PICKIT) for $36. It's a good way to get
off the ground, but it only works for a few of their smaller
(and cheaper) parts. Some people think they are harder to
program.


I haven't been tracking the 8051/6802 type chips. Some people
probably think of them as more like "normal" CPUs.


If you need more horsepower, lots of companies are shipping
ARM based chips.

You should have posted this to alt.religion...

My favorite so far is the Zilog Z8 Encore. You can program it and DEBUG it
in circuit! It has a jtag pin... I've had trouble with it in high noise
situations, however. probably the jtag pin picking up rf and crashing the
thing.

Another favorite are those tiny PIC 8 pin flash reprogrammable things. They
are just so totally cute, assuming you can get the darned software working
with no real feedback except perhaps a flashing LED or two. (You can run
their simulator, which helps quite a bit, but only in assembler). Like
programming with the 'printf' debugger, where printf can only print 'x' and
' '.

Unfortunately, there probably isn't a 'best' one, since one's preference
usually depends on what you've used in the past, and whats worked for you.
I'd want a posting from somebody who had recent experience with all of the
major competitors (which I don't have, unfortunately.)

The Z8 internal architecture is very nice.
Did they fix the clock thing? On the last Z8s I used, the cpu instruction
clock was Xtal/12.

The manual says 2 to 9 clocks per instruction. They also say "Up to 10 MIPS"
on the same page... So I'm guessing the clocks are the Xtal pulses, which
can run up to 20MHz. It needs an external crystal.

The PIC chip I'm currently using has a standard Xtal/4 instruction speed.
Its a RISC architecture, so one cycle per instruction, except jumps. So, I'd
say the Z8 Encore is about comparable. However, the instruction set on the
Z8 is also much richer.

The thing that sold me on PIC is the 8 pin package, however. I know there
are other 8 pin uCs around, but I noticed this one. Its really nice not to
have to ground 30 unused pins... The Z8 Encore also needs 3.3V, which means
you need to step down the traditional 5V (unless you go for all 3.3V.)

We have a couple AVR variants in 8 dip, like the 2343.
It's got on-board R/C osc, and can go up to 10 MHz, which is say 9 mips with
typical code.
I did a couple intro projects on this, available in the avr-chat group at
yahoogroups.com
One is an emulation of a Whelen Slimlighter, and the other blinks three
lasers in morse, with different messages simultaneously.
 
I am looking to convert a Basic Stamp application to a cheaper
microcontroller and was wondering if there is anything to aid in
porting it over?

I haven't found anything in Google so far - unless I'm using the wrong
search terms...

Why not use exactly the same 'microcontroller'?.
Click to expand...
The Basic Stamp, is a relatively simple PIC controller (available for
perhaps 1/10th the cost of the 'stamp' module), running an interpreter,
which gives the 'language'. It is the combination of controller, EEPROM, and
interpreter, that you are paying for. There are several PIC Basic's
available, that provide similar functionality, and with these, the code can
be written directly to the chip. Use one of the 'flash' chips, and no
seperate EEPROM is necessary.
Alternatively, several people have also attempted to produce their own
'budget' clones of the stamp.
Try:
http://www.hippy.freeserve.co.uk/diystamp.htm
which has links to several cheaper clones running similar languages. The
'PICAXE', is probably the nearest to what you want.

John,

Basic stamps are an overkill both in hard- and in software. But it is a
deleberate overkill. The stamp developers set a kind of a standard that is
easier to learn and easier to use then the whole range of PICs not to speak
about the other tastes of micros. The most obvious benefit is a short
application development time and that's expensive time. So both producers
and users of the stamps are happy and have no use for porting. I'm only
aware of to exceptions: The amateurs with more time then money and the profs
that want to make high volume. Both have to fall back on the skills and
knowledge of general pic developers. The first step in porting is to choose
an appropriate pic. Even this first step brings in so many variables and
requires so much knowledge of the PIC range that it hardly can be automated.
So if you want to port an existing Basic stamp application you'll have
either to look for a skilled PIC user or you'll have to dive in it yourself.

There are compilers that produce a binary PROM image from
Stamp Basic source (or something close to it).

PicBasic and PicBasic Pro from microEngineering Labs, Inc.
http://www.melabs.com

Heck, even Jameco sells it.

I think there are open source projects for equivalents.

You can chalk up 5 stars for the entire PICAXE range- & BS code very
compatible! Dirt cheap ( orders of magnitude LESS than BS2 ), ultra
user friendly, versatile & powerful. UK sourced ( www.picaxe.com ),
but they've been a sensation down under in NZ & Australia. Check the
likes of => www.picaxe.orcon.net.nz for enthusiasm. Manuka
