Nice idea, 

I'm really interested in stuff like this. Would be wonderful if it was going to happen.
If it would be possible to integrate a ADC and MP3 encoder as well it would be even better.  Or as a 
second SimmStick and you choose what you need. Just imagine a mobile HDD MP3 recorder....

Wait for the MAS3758D from Micronas - encoder, decoder, ADC, DAC, all on one

Don is doing a wonderful job of introducing new SimmSticks.

I had asked a while ago if there were any demand for a particular type of
SimmStick. I think I got a little action on the A/D converter front.

Are there any other ideas for new boards? (I'm thinking peripherals: like a
DTMF board, for example.)

Lynndon,

Your ToneSCADA device is very nice. If there is a desire to create an A/D 
SimmStick or DTMF SimmStick (or a combination), then I'd like to have the 
subject be open to Don and this group. It'd be nice to discuss the merits 
of this in this group.

Is there enough interest in this?

Lionel,

There are a large number of people that have asked for a microcontroller to 
IDE interface. Even without the MP3 stuff, this board would have a lot of 
appeal. ESPECIALLY IF IT COMES WITH EXAMPLES FOR FILE STORAGE AND 
RETRIEVAL.

Or, what if the board has a micro on it to talk to the IDE drive and 
communicate serially on the SimmBus? Imagine a DT111 doing some data 
logging and the results going to a drive...

The results of SimmStick Contest 2000

Well it is finally over. After several months of hard work and effort
from the contestants ( and the judging panel over the last few weeks )
the results are now finalised. The judging panel had a very hard time
deciding between the entries and have expressed their pleasure in the
high standard of all of the entries received.
On behalf of the SimmStick dealers we would like to congratulate all of
the contestants for the support and interest in SimmStick, without their
fantastic effort this contest would have been a non event.

These results can be seen at:

I'm confident that this is technically possible. The IDE interface is 
reasonably straight forward. Reading and writing raw sectors should be 
reasonably do-able.

Accessing the drive the way DOS does has a lot of overhead. If the goal is 
to datalog with a PIC (or other micro) and move the drive to a PC, then 
there is no way around the need to deal with the FAT and other DOS stuff. 
But if the drive is dedicated only to the PIC, then raw access may be the 
best bet. The drive would just be a big linear storage device.

My thought was create a SimmStick that has an IDE interface, a micro 
(PIC/Atmel/whatever), perhaps a power connector, and RS 232/485 circuitry. 
The micro would have dedicated code to access the hard drive via commands 
from the serial port.

Add this new board to a DT003, drop in your favorite DT controller board 
(DT101, etc) and create application specific code for data logging.

Neat, huh?

Make the drive readable by DOS/Windoze. I can't imagine spooling off a few
GB of data (or even a few MB) through a PIC serial port, even at 115 kbaud.
We're talking hours. Proprietary data formats are always (sooner or later)
a bad thing.

Why not have the local drive control micro do all that and present some
sort of API to the user, and hide the details of the FAT within the local
micro? There should be some more or less canned solution here, even if its
a single chip X86 controller or a fast 8051 with lots of memory.

Since we're on the subject, why even use an IDE rotating media drive? Use
SmartMedia - cheaper, 1/100 or 1/0000 the size and weight and power. Much
more rugged. 8 MB cards are under $20 at major discount chains. The
SmartMedia controller code is available in VHDL and could be stuffed into a
CPLD or FPGA. The interface is relatively simple. Cards can then be easily
read and written on a PC. Preformat them on a PC. With a USB reader,
dumping 15MB back to the PC takes only a minute or so. Lower cost than
Compact Flash, and more standard than the other memory sticks such as Sony.

Hi Folks,

With the talk of things that may find a home on a simmstick...

I was looking at an analog pressure meter the other night (it's
normally used for measuring the blowing strength in Highland
bagpipes, but that's a whole other story).

The setup consists of a Philips KP101A pressure sensor, a couple
of LM358M dual op amps and a meter.

I was toying with the idea of duplicating it using a PIC and
LCD display (or maybe send the data to a PC for display).

Anyone have any info on the KP101A?  I couldn't find much of
use with the search engines, so it may be a superceeded part.
If it is, can you suggest a modern replacement that is cheap
and likely to be obtainable in Australia without too much
drama?

I've seen that there are quite a few rocket telemetry pages
that would provide a good start.

Whilst I'm at it, I'd be interested in knowing what sort of
technology is behind tuning meters (such as the Korg CA10 and
it's ilk).  Could this sort of thing be done with a DSP/PIC
combo?  Maybe I could send both pressure and pitch info to
a PC for display?

Cheers, Dieter.

Have a look at http://www.simmstick.com/entries.htm ( I think )
There was an entry in the 1999 SimmStick contest for an aircraft altimeter
that also used a pressure sensor interfaced to a pic. I don't remember the
entry number of hand but it should be pretty obvious.

Motorola makes an extensive family. They are not what I would call cheap,
however.

I agree...

But with the addition of either the USB simm or the ethernet simm(??) or even
serial or parallel IO then the data could be read/written via a PC.

Sorry, nope (haven't looked too hard though).

Motorola makes a bunch of absolute and relative pressure / vacuum sensors 
(mostly for the auto inudstry, eg. MAP sensors etc), but usable for all 
sorts of apps. Like everything else, Arrow's probably the rep for Motorola 
here in Australia.

>Whilst I'm at it, I'd be interested in knowing what sort of

Don't know about the specific meter in question, but generally they need 
either a reference- (expensive) or transfer- (cheaper, but requires 
recalibration) standard oscillator timebase.  Then there are several ways to 
compare the amplified/filtered microphone input signal with the reference.

Thinking about it (but having not tried the idea...) probably the neatest is 
to use a phase locked loop and look for zero "pull" on the VCO.  In other 
words, use the abovementioned accurate frequency standard (eg. 440.000000Hz 
for A above middle C) to be the centre frequency of a voltage controlled 
oscillator in a phase locked loop.  If the microphone input signal is 
exactly the same frequency (eg. 440Hz), the input to the vco should be zero 
since there's no error between input and reference.  If the input is a 
stable frequency, but is different from the reference, the error signal will 
"pull" the vco either higher or lower until the pll locks again (at which 
point the error signal will be a constant DC). Buffer the error signal and 
drive a centre-zero meter movement and you've got a tuning meter!! The 
further from zero, the further off-tune, and you could arrange it so that 
the needle swung right for overfrequency and left for under. Note that it 
would probably come close to working for tuning frequencies that are (sub?) 
harmonics of the reference too, but I can't vouch for that.

Of course, that's just one way.  You could also "mix" the reference and 
input signals and look for "beats". Mixing directly gives sum and difference 
products, and it's the difference we hear as "beats".  So you could 
low-pass-filter the output of the mixer (to get rid of the sums), buffer 
that and drive the meter movement.  For perfect tune, you'd see the meter 
needle being still (at zero? depends if your filter/amp combo is dc 
coupled), for off-tune, it'd swing back and forth around zero, the faster it 
swung the further off tune it'd be.

There's probably other ways too, but both of the above could be done fairly 
cheaply at audio frequencies, and all they rely on is the accuracy of the 
initial reference (which after all is all you get with a classic metal $5.00 
tuning fork isn't it? you rely on Mr. Yamaha filing just the right amount 
off the ends of the forks to make them oscillate at 440.0000Hz, or 
whatever).

Hi.

I'm looking for a 72 pin version of DT201/DT202.
I would use one half (the lower pins) of this as an ordinary SimmStick layout. The upper pin numbers would I use as a kind of SimmBus.
From the top of my head those pins would be used for: D0-D7+ A0-A7+ALE+IORW+MRW+INT0-INT3

In that fashion you could have a bus design with say 3x72pin sockets for SimmBus modules, and 3x36 pin sockets for SimmStick modules.


But, is such a board available anywhere?

Not sure quite what you mean here Henrik,
The SimmBus is a 30 pin design.
I guess you are looking at a standard 72 pin edge connector on a
dt201/202 type proto.
You would delegate the first 30 pins to standard SimmBus pinouts, and
the top half is then open for more I/O signals as you suggest above.

The only problem is the pin count and pitch of the edge connector won't
match existing designs.

I have written a bit about 72 pin designs at:

this may or may not be relevant.

In that fashion you could have a backplane design with say 3x72pin sockets for SimmBus modules, and 3x36 pin sockets for SimmStick modules.

SimmBus modules that pop up could be: ethernet card, ram/eprom/flash card.

But, is such a board available anywhere?

What is the board in the picture at the top of that page?

Hi Don.

I just read your note at http://www.dontronics.com/ssinfo.html#72

I fully agree with your redesign worries. That's also why I'm suggesting that a possible 72 pin design should share the lower 36 pins.

For now I'm not planning to go that far.
I'd just like to get my hands on a few prototype boards to build a 8515 board, a ram / prom board, and a ether net board,
and combine them with SimmStick io boards as you would.

(Actually I'm quite chicken when it comes to designing, so I'd like to separate a design on separate boards to keep it simple.)

But planning ahead, this would allow for a combo mother board with a few 36 pin sockets and a few 72 pin ditto.
What can be reused? all io boards, and those controller boards that are used as intelligent io boards.
We certainly will need a new motherboard design, and a 40 pin micro card (8515/mega?), and then some new io/memory boards in this range.

There is a SIMM72 buss used by the Dallas TINI java module. I can't
recommend it as a generic controller bus, however. STEP+ has 2 x SIMM72
TINI bus sockets and an SBX socket.

We have an SBX card with LCD, keypad, and 24 high-current open drain I/O
bits, plus a 16C500 UART being released within a week (I'm just finishing
up the code for it).
http://www.systronix.com/expansion/sbx2/sbx2.htm

We have a SIMM72 TINI bus module with 2 x hardware UARTs supporting DCE,
DTE, and IrDA, about to be released. (not on the web site yet)

vinculum.com has a SIMM72 proto board about 2" tall (we have some here),
intended for use with the TINI bus, but the contacts are not dedicated so
you could use it for anything you wish.

We've thought about a board similar to our STEP+,
(systronix.com/tini/step.htm) with a Simmstick bus on it to allow plugging
on some ready to go I/O. I ordered all the common relay, pushbutton, etc
simmsticks from Wirz a month ago so we'd have some to play with and see how
it might all fit.

It is a y2k countdown clock with a complimentary message for resolving
the y2k problem.
A plastic toy my friend Mick found in a toyshop. About $4.95AUD I think.

I wonder if it can read presidential voting cards? :-)

Have you had a look at the http://www.dontronics.com/dt107.html
This is for 8515 and has a 40 pin header that matches the Basicx ram
sandwich. This board has been tested with the ram sandwich also. It
appears to be the only simple way of getting that extra memory hooked to
an 8515 that uses the SimmStick concept, because of the 30 pin
restriction. using a satellite board such as this, you could add all the
rom and ram that the micro is capable of addressing

This is where I lose you. 36 pin sockets? SimmStick is 30 pins, and
sharing the lower 36 pins on a 72 pin socket doesn't seem to add up.
perhaps I am reading you completely incorrectly.

Darn, I hoped it was a SimmStick with a built in LCD ;-)

I am looking at purchasing a full working Simmstick DT006 
WITH a MEMORY on board. The memory should be at least 64Kb.

I have spoken to Don about this. Don suggested 
I post on simmstick

Reasons: I have been trying to develop a special project of mine
on a simmstick-AVR-board.
The diffculty is finding the time at the moment to have a fully
tested 
simmstick-AVR-Board WITH at least 64 KB memory.
I thought I will work with the Simmstick board DT006 and add a 64 
memory chip and later a small LCD.
Trying to match the ATmel with the 64KB memory is so time consumiong 
that finally I realise there NOT enough hours in the day, plus my 
technical knowledge is NOT high enough in some very specific field 
of interfacing.
So I decied to stay with my programming in Machine Language and 
purchase part or the full interfacing.
But at the moment my project requires at least 64 KB memory, I
thought 
may be someone has already something working that I may use in part
or 
in full if that PERSON IS READY to sell me their OWRKING MODEL.
I contacted Mitsubishi for the 64kb MEMORY AND LAGER MEMORY BUT I
have 
some technical problem to interface the AT90S4433-08-PC to the memory.
That's why I thought if someone one in the group is prepared to sell 
me something already working so I can explore the possibilties and 
learn at interfacing AVR and large memory.

I have already from DON
DT006 fully assembled +a few other bits and pieces from DON like
AT90S4433-08-PC, ZTT-8 00MT, 24LC64/P, 2x16LCD.
FULL DONTRONICS STK200 Development System will.
Purchasing more parts IF IT IS GOING TO WORK is NOT a problem

This is a genuine request.
