AVR-Chat

Given that this is an AVR forum, not a PIC one, let me plug a product that I
have found very useful:  BASCOM.  A free 4k limit compiler is available and
supports most AVR chips.  The BASIC dialect is plenty powerful, lots of
library support (LCD, one wire, switches, AT keyboard, graphics displays,
etc) and runs circles around anything Parallax has to offer.  Full support
(some specialized libraries and 128k limit) is $60, but I have never run out
of space (granted I only use it for small quick projects).

 

Start at www.mcselec.com <http://www.mcselec.com/> 

 

Bascom is an editor, compiler, downloader and a limited simulator.  The
current crop of AVR chips come with a calibrated 1mhz internal oscillator
(most can easily be bumped to 8mhz and some to 16mhz) so literally a
no-parts (other than the chip,  power and the programming cable which is
little more than a cut up line printer cable) development environment can be
put together for a couple of $$.

 

A mega16 is $6.50 in singles, run it off of three AAA batteries; spend a
little extra on a breadboard, some LEDs and switches and resisters.  How
cheap can you get??

Subject: [AVR-Chat] Re: (OT) PICAXE

 

Another easy-to-use MCU you can consider is, the SX family distributed by
Parallax (used to be from Ubicom). I suspect Parallax is trying to set a
difference between their expensive part (read, premium), Basic Stamp family
and a low cost version (SX). You will be surprise, SX is quite powerful. The
only caveat is, you have to buy their proprietary SX chip-programmer, the
SX-Key (SX Tech Tool Kit PLUS). Its USD 99.00. But the number of parts in
the package and plus a BASIC compiler that comes free, I think , it value
for money. I compared it with a good Basic program for the PIC which can
cost up to a few hundreds of $ ! 

 

As for the SX chips, it cost only a few $ each. Best of all, Parallax is
selling 2 high quality SX protoboards for a mere USD 9.95 each ! Great for
projects but does require the SX-Key though. Check out their web site (
www.parallax.com )

 

PS: I am not in any way related to Parallax. In fact, I quite dislike them
due to their high priced BS until they lunched the SX. But then again, I
vote with my $.

 

cheers,

I've used PICAXEs.  They're pretty cool.  A nice, cheaper alternative 
to BASIC Stamps.  I don't use them anymore, because I'm much better at 
programming PICs now and PICAXEs, of course, have limitations and 
overhead.

I would definitely recommend them for schools, though.  The cost is 
like 1/4 of what Stamps are.
