I believe I found the problem !
On the DT111, lines RB6 & RB7 are used, under same cases, to drive an 
output signal through a sort of low impedence network.
When the hw is set to drive the load, programming does not work 
anymore...I put two jumpers between and now it's ok.
It makes sense, right ?

Hi Tim, the chip used for the USB interface is the FT8U245AM, and there
are full data sheets, schematics, application notes, and drivers are
available from: http://www.ftdichip.com/
so I hope this data will clear up all of your questions.

You mean you have rb6 and rb7 loaded?

Yes that will kill the programming.

this is basically why I have a load and run position on the dt001 board,
but I can understand if you used the dt111 proto area for prototyping.

Hi

first of all I am the one who made the SimmStick specsification :)
will be in the UK/London 21-26th Dec, I wonder if there are anybody
in the UK who would like to trade some simmstick to beer :), well
I am having trouble getting my deskdrawers empty and there are lots
of simmstick boards to give away, and so I am wondering maybe there
are someone in London or closeby who want to help me :)

cheers to all

As part of a project, I'd like to be reading a mouse probably with a
AT90S1200 to get all that nice buffer ram for cheap.  I plugged a
serial mouse into my DT006A using a gender mender but don't get a
peep out of it.  I've read that mouses get power by using all of the
lines on a 9 pin and wonder if anyone here has done mouse input or
knows where I can get examples of wiring to do that.

The project is an alternate mouse device but I need to have a mouse
also be able to "pass thru" if I can.  It's cleaner than a switchbox
which is the fall-back position.  If I can somehow get the mouse read
using the portB pins of the 2313 main brain then that would be even
better as long as I have code room and 5 pins for one other small
function, the alternate interface itself and a switch for which to
use.

Don; the rAVeR is a great little startup board!  The BASCOM makes it
very simple to code without much concern over details.  I don't know
how optimized the output is but I'll take it all one step at a time
and this little sucker is plenty fast for my needs.

With the DT104's, do we have to populate the EEPROM's onto them?
I'm a newbie and to tell the truth, don't know how I would use them
if I had them.  I guess I need to see more simple HOWTO's that are
specific to Dontronics boards.  It took me a very long time to decide
to take the plunge partly due to money and stability but there was
over a month that I wasn't sure just what did what and what else I
would need.  I'm sure other beginners are in the same boat.  General
info is good once a person is "in motion".  Specific info down to
finished working details may sell more parts and start off more
customers.

If someone can't help on this group, ask at avrfreaks.net forum. they
have about 4000 users, which is a whisker more than this group. :-)
no doubt someone as done the interfacing to an avr, possibly with
bascom.
I know I have seen many examples over the years, but would need to do a
search to find them.

> With the DT104's, do we have to populate the EEPROM's onto them?

you only populate what you need to use. in most newbie cases, you don't
need it until you find a use for it.

this is where you need to follow up with the information that is
avalable on the web. Most basic things have been done with all micros
including AVR's.

have a look at:
http://www.dontronics.com/atmel.html for my avr links to many sites as
well as the avr web ring.

AVR 16 channel serial servo controller for robotic applications is just
one link that I have added in the last few days, but I hope other users
can give you additional info via this list.

http://www.google.com is an amazing search engine that people don't make
use of.
try "at90s2313 mouse"
good heavens, better results than I thought.

Hi Neal, I did not completely understand your question but,  it it can help
you, follow this link; it brings to a number of different information (Hw,
wiring, protocols,ecc) on mice.
By the way, in my opinion ePanorama is absolutely the best site for electronic
information.
Good luck (a happy New Year, to Don too)

Yes, thank you.  It helps and is also a bit scarey!  Now I see that
what I do will not fit all conditions whatsoever.  Since PS2 mouse
is the most common, that may be the way to go.

I have also found one definite "gold" site:  
http://w1.132.telia.com/~u13205992/buttonbox/index.htm
that should interest anyone in the hobby.  Look at the KBSnoop part.

I found another site of more and wider interest, the guy is good:
http://www.geocities.com/CapeCanaveral/Launchpad/3632/
His name is Alberto Ricci Bitti and he has many very interesting
projects.  He uses the AVR's quite a bit, shows and explains well
what is done and why.

I may make a universal mouse input device if I can figure out how to 
motorize the mouseball.  That would cover all but optical mice and
if I do it right, even those would work.  It's "dirty", but then
I'm getting tired of the range in hardware and software out there.

Most of those links were about using a mouse to run somebody's
programming software or like that.  But a couple were gold. <s>

The ePanorama link and the KBSnoop link were the best.

I've seen that for serial mice I'd need to supply power on 2 lines
and likely 12V at that.  No biggie, I could carry that from the
lines from the PC serial link and know the power would be right.
What would a development board be without a few extra wires?  LOL!

You'll be getting an order for boards and oscillators soon as I'm
sure just which ones I'll be needing.

thanks Neal, remember that there are several hundred users on this list,

However I am looking at the two sites you mentioned.

Yes, a real bummer.
I designed two OSD projects for EA based around that chip, from which 
Lionel developed the DT108.
There has certainly been a lot of call for a replacement, but it does 
not look easy.

I played around with another ST chip, but it was a bugger to use, not 
nearly as nice as the 5730.

I think the custom solution has to be the way to go for longevity, 
these OSD chips have a bad habbit of becomming obsolete :(

Yes I know the projects well David. I did have a good look at them :-)

Lionel, any more on the custom job your were considering?

Guys,

I am currently doing a project based on the Microchip 2120 IR device. I
have also used the 2150 as well.

Is/has anyone done a SimmStick with irda capability?

If not, does anyone have any comments on a possible F877/IRDA combo? 

Rgds...

Yes we are working on a UART with IrDA output option as a JSimm/SimmStick 
board. It will have some other options too such as Dallas OneWire network. 
This can be used by most any SimmStick system or our JStamp and JStik products.

We are invloved in an open source Java IrDA project as well, there are 
links at our website.

Another one in development is CAN net.

 You could look at

http://www.myson.com.tw/mtv/MCU.htm

and specifically the 64K FLASH ISP+OSD model

http://www.myson.com.tw/mtv/data%20sheet/Mtv230M/MTV230M(AE).pdf

 This integrated OSD is one of the reasons the separate OSD devices are 
being phased out.
 This one is ISP Flash + STD 80C51 core, so suits your application.

 No sure of the stocking, but you could always suggest a 
'Samples for App-note' trade to the vendor :-)
