IDE Project Update

No pics or schematic yet, but I did get the low level routines to work. So far,
I'm only using 28 out of 33 pins on this 16F877 PIC. The other 5 will be for
serial communication & ADC.
Hopefully, I'll have more time this weekend to update my site.

along with an updated schematic.
Since this is becoming more PIC related and less Stamp related, are there
any PIC groups around that anyone would recommend?
Once this project is finished, it will become Stamp-related again. All of
my recent efforts have gone into developing PICDOS. Eventually, it will be
a simple 2-wire I2C peripheral for hard drive access with FAT16/32
capability. Right now, I'm focusing on FAT16, but once it is operational,
those routines can be easily modified to support FAT32.
Also, I'm working on a more permanent hardware arrangement. Does anyone
know where I can get a few prototype boards made for a reasonable fee? The
only place I've found so far is http://www.pcb-pool.com that Jeremy
referenced on his site: http://www.geocities.com/skimask87

Since it is being designed for use with a Stamp it is Stamp related
isn't it?
The main PIC list is at http://piclist.com/techref/piclist/index.htm you
will probably want to set digest mode the list is extremely busy and can
get a hundred or messages a day.

Check out http://www.custompcb.com/index.shtml I have not used them but
the have a program where you can get a free board by putting their link
on your web page.

The PICLIST operating out of one of MIT's servers is probably the best
place. The easiest way to join is to head over to <www.piclist.com> for
the appropriate links and instructions. Also - would you consider leaving
a note to James Newton (webmaster of piclist.com) about what you have done
- your project sounds like one that is a natural for his site.
One other think - if you do finish up with a working version written in C,
there is a bit of a contest going on at piclist.com and at Myke Predko's
site - you might wind up with free copies of Hitech's C compiler and the
Salvo real time kernel. They are worth quite a lot - the compiler is 895US
and I think Salvo is similarly priced.
I would have mentioned the above sooner but I thought that you were already
aware of the piclist.
Congratulations on your success!

Barry,
Take a look at www.expresspcb.com . I haven't used them yet, but know
several who have, and all are happy with the quality, turn-around time and
price. Download the free PCB layout software from the web site and start
designing your boards. The software calcs the prices before you order, and
you order right online. If you use their services, please let the rest of
us know what you think.

2.5x3.8" board for $59.00
great deal don't forget if your board is small enough you may be able to
fit 2 or??? on a single board.
I have used them several times I have no complaints.
their software is super easy to use.
as a matter of fact I wish they would make a retail version of it.
regards
victor

simple schematic--especially if you are still making changes. However, my
needs were for a four component board. I just copied and pasted them so I
got a 3x4 array in my 2x3 board. (The cheap $59 service only allows for one
board size.) The boards were better than I'd have made myself, and arrived
in a timely manner. I'll probably use them again when I need another simple
board. I won't waste my time with them again on a complex board. (Why would
I want to do two layouts, when I could send my file to a shop that accepts
standard files?)
While I haven't used them yet, A guy posted the message below on the
picbasic list. I plan to try them out for my more advanced boards.
Good luck!

Advanced circuits has a $33 per board special. The offer $33 per board
(minimum 2), up to 10" x 15" and it includes solder mask on both sides, and
silkscreen on the top. Here is the link if you want to check them out.

& LCD are already on my site with a full schematic that the PCB was
made from. But, I'd like to eventually make a kit available so
anyone can get the PCB and program it to do whatever they want.
They'll have to come up with their own way of storing/reading data
from the hard drive. Or they can buy a pre-programmed PIC that has
PICDOS on it and use it as a FAT compatible peripheral for their own
project.
