Newbie assistance for Atmel at89c2051 project

Greetings everyone,
   I have a specific application I want to put a atmel processor to. The 
processor would be along the lines of a AT89C2051-24, ideally something 
I can program easily say using their ISP system.
   I have a proto board design I found on the net for said mcu and it 
pretty well fits what I need for this. However. Since I have NO 
experience in programming one of these things. I was curious if there is 
a simulator that you'd recommend I could use to learn how to use this 
beast before I launch into building the real thing and realize I can't 
make it work.
   I do have windows machines, but I prefer using my Freebsd boxes. Any 
answer right now will be helpful on this. I'm doing this project for a 
non-profit organization and I have zero budget save what I'm throwing in 
which isn't much.
   A general idea of what I'm going to do with this. Is use it to 
translate a 3x4 matrix keypad output into a serial ascii equiv. So a 
computer can check the info in a database and respond with a command to 
start a motor to open a garage door. The mcu will also determin if the 
door is open or closed.
   That's the general idea of what I'm doing with this. Any and all 
assistance is greatly appreciated.

The 2051 does not support ISP.

If you need a small ISP capable 8051 compatibe controller, look at
the Philips LPC9xx series (especially LPC921/922 in your case).
They also have the needed software for ISP download.

For tutorials about programming etc, look at http://www.8052.com.

I know the 2051 doesn't have ISP. But thank you for the suggestion and 
link. I'll start digging into it. I'm not fixed on any particular mcu or 
such. I just want to spend a few dollars as I must to get this thing up 
and working.

I'm stunned and amazed at the quick reply. Keep them coming and thank 
you all in advance.

Tilmann Reh,
   Wow this LPC922 looks great so far. I've been looking at the data 
sheet and it has something I had in the corner of my mind as a good 
thing but not totally necessary. A RTC.
   The 8052 site is a bit cluttered but I'm starting to get around about 
it. Thank you again for the information. Is there a good protoboard 
design out there for this chip?

If you are in such a hurry, you might want to look at CYGNAL parts.

NEWS FLASH <http://www.silabs.com/products/microcontroller/>

Their development kit has hardware and software from $99 to $149.

Check out the phriphals you need and select a kit.

No, forget them - absolutely oversized and far too expensive
for this application.

It *is* a really great chip. :-) And d*mn fast.

I don't know of one, but you could do the development using the
LPC932 (the great brother) and later use the 922 instead (they
are almost completely compatible).
For the 932, there are some boards available.

Look at http://www.lpc900.com.

well for a few cheap dev / proto boards
from US$29 - $70 (no lpc9xxx)

http://www.futurlec.com/DevBoardAccessories.shtml
These guys can take a up to a few weeks to ship
but are cheaper than most other places.
(can put other manufacturers 8051's in these boards as long as they are pin
compatable)
If you order any of their boards
order the extra chips(eeprom , rs422/485, rtc(real time clock) etc)
at the same time. And any of the accessories - lcd.

Also can run most of their boards faster(depending on micro)
by replacing the crystal with a high speed.

I ordered a 932 development board for $59.00+ tax/shipping It seems to 
handle pretty much what I'll need and since it's already assymbled I 
won't have to worry too much about getting all the parts.

I'm excited, this is the first time I've done anything like this. I'm 
use to working mostly with servers and fixing TV's and stereos and stuff.

Thanks very much for the points and suggestions. With luck by sometime 
next week I may be starting to talk to my first MCU. I've been looking 
at the simulators availible so I can test my code and all before I start 
talking to the board. Any suggestions?

I've got SDCC running on one of my servers, though I haven't quite 
figured out how S51 works it is definitely going to take me some time to 
  get comfortable with all this.

Many thanks and happy new year.

Davon

DO  NOT use the SDCC compiler. the LPC kit should come with a Keil
compiler. Although this has a 4K limit on it you will probably be able
to compiler far more code than with the SDC compiler.  

The Keil is extremely good at optimising ad data overlaying. The SDC
isn't
