People,

I have looked at the PCF.... datasheet, and he is correct. But, The
devices can sink 10 - 30 mA, so if you use pullups, that would be OK.

Whether there is room for the pullups is another story. Do the ULN's
have pullups on the inputs? - don't use them so don't know.

Hi!

Yep. The PCF8574 can sink enough to drive an LED, but cannot source enough 
to drive the ULN2803. At least according to specs. Again, the little devils 
on my bench work together without any problem, but a pull-up resistor 
package (SIP) appears to be the way to go.

Thanks again for all of this great feedback.

Take care,
-Rob

Good Morning.

Don MKenzie said:

I am now! [on the list :) ]

I said:

> > 2. stuff U1/2/3 with resistors for input or low current, low 
voltage out

When I made my suggestion about opto stuffing, I meant:
Install one of the following:
  4N25 series transistor
  4N32 series darlington
  H11A series ac input
  H21A series transistor (4 pin)
  MOC3010 series triac
  MOC3030 series zero-crossing triac
in the pads of U1/2/3. If the opto is installed with pin
1 "north", then this port is an input. With pin 1 oriented
in the "south", then this port is an output.

Naturally, the H11A suggestion above is for an opto-isolated
input. And the MOC30x0 suggestion is for an opto-isolated 
output.

For opto-isolated outputs, the PCF8574 has to drive the 
opto LED on pins 1/2 of the opto-isolator. To make that
happen, we need to introduce either a series or parallel
resistor. The recent discussions about fixing the ULN2803 
drive problem suggest that Rob is going to put in some
pull-ups. This would be enough to drive the opto's LED.

For instance, suppose the opto is connected as this:
u-opto is a ISP817 4 pin opto-transistor
u5-4 to u-opto-1
u5-5 to u-opto-2
u-opto-3 to J2-2
u-opto-4 to J2-1
3k pullup on u5-4
To drive the thing, the programmer must set U5-5 low;
this is the cathode of the opto's LED. Then the 
programmer can switch U5-4 high and low to drive
the anode of the LED. The 3k pullup resistor will 
feed 1mA into the photo diode, and we should be able to drive
a 1mA load. 

We use two io ports on the PCF8574.

Change the opto to a MOC30x0 device, and you can 
control AC loads. Low current loads :) These are 6 pin
devices, so you use up 3 ioports on the PCF8574, but that's
the price of flexibility.

To make an opto-isolated input, connect as 
follows:
u-opto is a ISP817 4 pin opto-transistor
u5-4 to u-opto-3
u5-5 to u-opto-4
u-opto-1 to J2-2
u-opto-2 to J2-1
To drive the thing, the programmer has to set u5-4
to a low. This will ground the emitter of the
photo transistor. Then the programmer should set u5-4
to a logic high. This will source 30-300uA into the
collector of the photo transistor. The programmer can
then check the level of u5-4 to determine if the
opto is turned on.

Someone somewhere will have to put a series resistor
in line with the opto LED; probably off-board.

Again, this wastes two or three ioports, depending
on whether you use a 4 or 6 pin opto. I expect most
project will only use one or two of these along
with 16-20 regular digital ioports.

..........

The load or signal source can be connected to 
J2 ribbon cable. Or, I'd probably insert some 
screw terminal blocks into the pads
of J2 and wire the load in that way.

[Rob, does the new layout allow for terminal blocks.
Unfortunately, the cheap terminal blocks are on 0.2"
centres.]

..........

Rob, have you considered adding an alternate pad set
for U4/5/6 to handle the pinout of the TDA8444 ($2)
octal DAC. This pad set could be offset by 0.1"
if you have the room. Then the outputs could carry
on out through U1/2/3 (stuffed with jumpers or
protection resistors).

On the other hand, perhaps the PCF8591 ($3) might 
be a better choice: 4 ADC and 1 DAC. Yes, better I think.
...........


Nice job Rob.

Thanks, Pat. (On behalf of everyone) Welcome to the list.

I clipped all of your opto-stuffing, uh, stuff. :-)
This advice would make a great app-note for the DT209.

In fact, it would be great if any creative use of any of these boards could
be shared with everyone.

.2" Terminal blocks can be used, although there are trade-offs.

No, I have not considered any DAC for this board at all. I have been
thinking of a board that would support perhaps 4 or 8 A/D converters and a
DAC or two. Perhaps the TDA8444 or PCF8591 on this. Some analog gain
circuitry. This is just vaporware at this point. I'm open to suggestion. Or
if someone else want's to do this design, have at it. I'm OK with that.

I want to be careful not to make the DT209 overkill. It'll end up being 3
feet long. (Or ever worse, a meter!) 


> Nice job Rob.

Thank you. And again, thanks for the great feedback.

I think the opto "stuff" is really practical now that there
is a pullup resistor available.

Yes, perhaps too many variations is not a good thing. But that's
what I really like about the DT101. Tight, tight, many option,
and every spare area is sea-of-holes.

I'd be happy to look at an D/A, A/D board; I'd probably put
a DS1620 on there for temperature. Is there anything else
people would like:
 -phone line interface (probably illegal)
 -X10 interface

Yup. Agreed.

Have at it! The 1620 is a great idea!


> Is there anything else people would like:

>  -phone line interface (probably illegal)

A co-worker is sketching out a Simm board that has a processor to monitor
lines and communicates with an external modem to serve web info (or
something).

A phone line connection to monitor and produce DTMF is also a good idea. The
drawback is that making it international is impossible. But if the SLIC is
off-board, the Simm could contain the DTMF parts and perhaps audio parts.

>  -X10 interface
 
This is on my drawing board. I intend to make it.


Would anyone be interested in making a motor interface? Perhaps an H-bridge
on a Simm?

Would an embedded PIC that has multiple channels of servo control be a good
idea? How about stepper motor control?

-Rob

Gday Don,ALl,

Yes but was he `driving' with a low (good design practice) or with a High?  I
would suggest that they could NOT light a LED with a HIGH.

I would LOVE one of these beasties..... but please design so that it works on
240V 50Hz as well.

Is that a `stepper motor' driver? If so YES!

Yes please.

Have been looking at H-bridge and also feel there is a market for it
combined with the servo controller. Need to be very very very careful of
layout on this one due to the very high currents involved with motor
control.

In my spare time I will release ( free ) software for an 8 channel servo
controller. The hardware is trivial and not worth laying out a PCB for. It
consists of a DT101 ( with PIC & RS232 ), a resistor for each servo and a 3
pin header for each servo.

Combining the servo controller with the motor controller has applications
for robotics.

Ha ha ha ha yeah right. Who would ever need one of these!?! 50Hz! Ha ha ha. 
Never!

OK. I was kidding about the 50Hz stuff above. There are patent restrictions 
on directly modulating X-10 onto the power-line. My intent was to drive the 
TW523 made by X-10. But is there one for 240V?

In a previous life the company I worked for licensed driving the power line 
directly and we had equipment for 110/60 and 220/50. The task is not too, 
uh, tasking...

As far as the motor designs go: These are suggestions at this point. I 
think that they would be valuable SimmStick peripherals.


-Rob

Can I suggest a decent 12 bit A-D interface, LTC1298 or similar.

Cheers

Hi 

I've made an Stepper motor driver using an Simmstick (Lawricel SIMM100 for AVR 8535 )
and 8 HMOS drivers. 

It runs ca. 100V and ca. 20A 

Believe me, your going into a heavy world.

If U use this to control a real stepper ( below .5 ohm DC )  you will come into the problem of current restriction for low frequencies.
U will have more than only 10 - 50 A peek's..........
 
Cut down this current is not easy and you will run into severe EMV problems.

I was able to crash / STOP the AVR 8535, so it's no more accepting an NMI...... ( can mean all drivers of the bridge shorted !!!!)
Only power shutdown helps...

The power part uses two layers, and half  "euro-format", the simmstick is plugged on then end.

My advise is, U shut never handle such inductive currents over "Simmstick contacts". 

I'd propose U,  to use modules like the once from allegro ( ca 2.5 A ), and not go into the real stepper applications.

Regards

Who knows??? I have never seen anyone advertise or use it over here... I have
read with interest in cc ink etc and would like to do some experimenting with
it.  If you need to buy some sort of commercial interface to use it then I'd
guess that its a waste of time as these, assuming they are available here,
would be quite pricey.

Todd posted to me several times also.
I told him the SimmStick User Group posting was OK as it was related to
our game, and providing it wasn't abused. "Could I complain about that?"
:-) The same basic rules apply on the PIClist, so I have to defend his
posting to the SimmStick list, as it was the first we had seen from him.
In fact, I didn't even raise an eyebrow when he posted. All was well
until I learnt of the potential virus.

However I did ask him to remove me from his private mailing list. I also
informed him what appeared to be a virus script was attached to his
emails, and several people had complained to me about this. They also
said they would speak with Todd about the problem.

I know Todd is a responsible adult trying to make a living like all of
us, so I also know he wasn't aware of the virus, and it wasn't
intentional. 

We have seen similar things from many members in the past few months,
and it has been done unintentionally, and without their knowledge. It
may be you (or me <gasp!>) next time!

The 'spams' seemed revelent to me, but what's this about an attached
virus script? Can you tell me more about it please? Is this an Outlook
Express mail type of virus, or something else? What's it called? 

	I didn't notice if the messages were sent through the Simmstick mailing
list, or not. If a virus was passed on through the Simmstick mailing
list, I think someone has an obligation to post a message informing the
subscribers of the situation. One of the reasons I keep my mail on Juno
is that it provides some primative protection against MS mail virus
scripts (why else would I put up with this clunky thing?). 

	Thanks for the info,

	Mike.

It was a non productive script and we had no reports of any problems
with it.
You can re-examine the message in the SimmStick archives without harm,
(http://www.egroups.com/list/simmstick/ message 151) Actually, it is a
javascript that must run on an html page. How it is invoked being
attached as text to an email, i have no idea. It also appears that the
posting on the list is only 4 lines long. The original was about 40 to
50 lines of javascript when it was posted to individuals.

re the question of the message being a spam, i told the author is wasn't
when he posted to the list, providing it wasn't abused. As this was the
first time Todd had posted, it seemed in order.

Now the real problem was he appeared to have had mined email addresses
from several lists and posted unsolicited mail to these people including
me.

I promptly asked him to remove me from his list, as i had never
subscribed as he suggested.

I didn't know there was a script embedded in the email when I first
spoke to him, however not only I, but several members on this list and
others have made him very aware of it.

So the problem isn't posting "On Topic" to a list, it's spamming private
individuals using mined email addresses taken from lists such as this.

The attached script was unfortunate, and possibly beyond his control. We
have seen this many times in recent months.

I now have many angry messages from people that have refused to purchase
from the company that recently mined lists for the purpose of sending
SPAM email.

Others have asked my advice about sending unsolicited email, and I have
told them they would be absolutely mad. Start a newsgroup, or a
subscribed mailing list! I have done both, and they are working well for
me.

The SimmStick eGroup, formed DEC 7th 1999, now has 135 members, and the
DonTronics Listbot Newsletter, formed Dec 1st 1999 has 327 members.
(Bruce Reynolds: thanks for the advice on that one) :-)

These are customers and potential customers that have subscribed to
these lists. You don't need to SPAM. You have to promote your products
via a sensible healthy exchange of messages from users.

It makes for better product announcement, promotion, development,
marketing, and is a self help mechanism for users/customers, therefore
taking a lot of the load off me responding personally to questions on a
one-2-one basis.

These are great Internet tools that many companies aren't using at all,
and with zero or very small costs involved. Why not try it?

when you post to a list on a related subject, and don't abuse this
privilege, i don't mind, but when you post to the list owner (which is
me) and to me also privately, I end up with 3 messages, and i call this
spam, as i didn't ask you for it, so please remove myself and the
simmstick group from any further postings. i will request all members of
the list to boycott your company, and will pass this message onto other
lists and individuals.

We won't tolerate unsolicited spam!!!!

Hi Don, interesting that there are two spams now - one of them for
bathroom
fittings for heaven's sake! (stronger expletive deleted) !

That makes me suspect it is the work of some freelance spammer doing it
as an agency or something similar.

I've reported it via the automated spamcop.net as I hope you have, the
more folk that complain about these abuses the quicker the abuse might
be dealt with.  I am also mailing the addresses given in the spams to
say much the same
as you have said, won't use their company, will advise everyone I know
not to buy from them etc.

I've also done the same on their website "contact us" addresses and in
their guestbooks.

I see you did one of the guestbooks too, good plan.


Cheers
Andy

P.S. Wanna buy any bathroom fittings?

For this list, it gets back to a full time moderator, or occassional
spam.

If potential members would join first, then post questions, moderation
would work, as there would be very little messages to approve/disaprove.

but when you see unsubscribe commands sent directly to the lists, you
know it ain't going to work. :-)

anybody wanna be a moderator? (or buy bath fittings? :-))

Cheers Don...

Yeah not everybody will play the game, but there are things that help...

I run a couple of list and have found two things that ease the load. E
groups allows you to add a text message to the end of each outgoing
mail, In there I have details of how to subscribe, unsubscribe and
change your personal status at egroups.

The other thing that helps is to restrict posting, viewing the archives
and everything else to members only.

> anybody wanna be a moderator? (or buy bath fittings? :-))


Did you know that a DT001 with a couple of SIMMs inserted makes a
wonderful soap-rack?

I manage two lists which require joining to post to the list. So far this
has prevented all but one spam in several years. The non-member posts
bounce to me instead of going to the list. The inconvenience of having to
join is the tradeoff for spam blocking.

Hi Gang,
I have posted a reply to Sue and explained to her that she is posting to
a group.

I have decided to take a harder stand on the group regards posting by
non-members, and will set the flags so you don't see spam or these types
of messages posted by non-members.
It will also mean I will simply delete any non-members postings.

Cheers Don...
