Subject: 24LC64 I2C routines

   
Has anyone got the I2c routines to Read/Write to a 24LC64 EEPROM with 
a 16F877 on a DT206 board?

Microchip has a couple of app notes that have I2C code examples...I've not
used them.

I am about to use the I2C routines included in FED WIZ C in my next app.

Speaking of 24LCxx. I notice that there is space for 2 on the DT106 board.

Unless I'm mistaken, be aware that the 24LC08 does not connect the A0-A2
pins...thus, only one could be addressed on this board.

Don't ask me how I know... ;-)

Not a problem with larger EEPROMs.

Mac

Subject: SimmStick CAD File?

   
Hi:

Is there a basic SimmStick CAC file available so that I can
order a SimmStick for a custom circuit. Of course, I assume
this file would just include the basics (such as the connectors
and the board size).

If not, is there a service that will create PCB simsticks
given the details (other than the connectors)?

Thanks in advance.

There aren't any real standards for PC layout databases, each vendor is 
different. The common output is a gerber photo plotter file, but you don't 
edit that file to create the board layout.

We have a SimmStick/JSimm template in PCAD 2000, if that does you any good.

We can export to DXF.

Thanks, Bruce. I'll have to check what formats I can use. As you know I'm
back to circuit design after 20+ years, and things a changed a bit.  :)

I can do that; I believe there are a few open source programs to do this.
I have to check on the formats that they accept, though.

Have a nice day!

Hi Alex, I have thoughts of doing something, and I know of one or two
others also. Not sure how far away this will be.

Also I have thoughts on enhancing the Simm Bus, but still retaining the
current bus pinout.
I hope to be able to release some details for discussion within a week,
maybe a few days.

This depends on my mother-in-law's geographical movements.-)

Don:

My views as a very recent user of your excellent line might not
be very valuable, but I want to send you my comments anyway.

Unfortunately what I see as the major problem with the simm
connectors is the distance between connectors.  The distance
is very tight for dips and other components.

A system based on 20 x 2 will accommodate some expansion.
Certainly not some of the larger AVR chips.

Your idea of the 40 -> 64 expandable design looks very good.

Yet the whole concept of adapter boards makes me think:
I will certainly not upgrade my existing projects, they will stay
as they are.

The 30 pin SimmStick is a beauty.  The size is so nice.  And
I have used the stacking without the motherboard to make them
fit in tight spaces.  I HOPE YOU DO NOT DISCONTINUE THEM !!!
I think this feeling will be shared by others.  It fits the small chips
very well.

I greatly dislike the "pins on the edge into a motherboard " concept
because it is mechanically very poor.  Stacking boards is much easier
and the boards can be connected with standoffs to keep them together.

I would like to see a new line of 40->64 boards that have been
designed from scratch with the new chips in mind.  Boards that can
take other chip formats.  Surface mount would be nice but it is hard
for some people to work with.  PLCC sockets, however,  are easy
to work with, and inexpensive. Also, a board with crossed strip
pattern would be nice.

Thank you for your work in developing boards that make working with
micros easier !!!

Hi Fred, thanks, I welcome all feedback, including the reasons newcomers
chose SimmStick. 

We knew right from the start that in reality a dual Simm socket, would
basically only take one board, unless all components were surface mount.
As singles and dual sockets are about the same price, cost wasn't a
factor, but sure, board space is.

I have snipped the rest of your message off, so that others can comment
on your thoughts, however please understand that as I have so much tied
up with SimmStick, it will not be discontinued in the immediate future.

My main thoughts came about because of the Simm socket. How is everyone
getting on with sourcing them?
How many are using only the male/female pins?

I have thousands of sockets in stock, which will keep me going for a few
years, and I should be able to get more.

Are there any DT simmstick hardware options for using this chip? If not, 
what's the largest memory-capacity Atmel processor that I can easily get

Hi Paul, basically yes, if it is in a dip package and pin compatible,
then it should be OK, but we haven't designed anything for the mega
chips yet, and haven't moved into them ourselves, as they have been
expensive and too hard to get generally. I hope this changes in the
future.

PIC seems to be on a bit of a roll with their new pic18Fxx2 range right
now.

Subject: STK500 ISP and Simm100 intermittent programming fault.

   
Hi,

With the SIM100 connected to the ISP of the STK500, on approx 1 in 5 
attemps to program a 8535/Mega163, or reading the signature bytes, I 
get an error - the error occurs right after issuing the command.

When there is NO error, the programming works without a hitch, it 
only seams to be when the STK500 tries to make initial contact with 
the AVR. (reset??)

The error I get indicates failure to read device (as if it were off).

Versions - AVR Studio 3.52 and STK500 (ver 1.2). 
Im using the VTG from the STK500.  8Mhz xtal on SIMM100

I have two SIM100's and both give the same error. One has the minimal 
config (no 232,leds,adc, etc). Because both boards show the same 
fault, and I have tried two AVRs, I'm sure its not a soldering or 
component fault etc.

Both are using RC resets (10k / 10uF) , and this is what I think the 
problem relates to. Am I right, and does anyone have any fixes.

Thanks
Mark

Have you linked a wire on J6 for the reset, since you only use a
resistor/capacitor have you install this jumper?

See http://www.lawicel.com/simmstick/simm100/ for instructions.

Other than that, I do not know what it could be.

Lars,
yes, I have - its hard wired!
Still love your board and SIMM concept though, thanks!

Hi,

Then I suggest, just as a test you install a proper RESET
device, since some "old" AVR's like the 8535 could be kinky
to start proper. If that doesn't work, I should blame the
STK500 or something in that area.

Yes, just placed the MAX701 on order!!

BUT,throwing caution to the wind, I replaced C12 in the RC circuit 
with a 100nF to see what would happen - and the problem has gone away!
I hope this value isn't to low for the RC Reset to work properly when 
powering up - we'll see.
Does anyone out there know why the higher value (10uF) causes the 
STK500 ISP to fail, as I described in my original submission?

cheers

It should actually work with just a Resistor up to VCC, but the
problems with the early AVR's like the 8535 (not Mega163 etc.) is
that the brown out doesn't work in them, so if you have a too low
value of the capacitor or none, the AVR will start up early on
low voltage and the EEPROM doesn't work there at the low voltage
and you could loose content in it. The same if power goes of, the
AVR keeps then running on lower voltage and if you have EEPROM
routines, they fail and you loose data. Thats why you want it to
hold reset a bit. This is why an external Reset device is the best
solution. If you on the other hand have Mega163, Mega323, Mega32
in it, you just need a pullup resistor to VCC anb program the fuse
bits in the AVR to correspond to the VCC startup behaviour (read
datasheet). The problem you encountered is probably due to that
the STK500 is too fast in asking for the device signature, so the
10uF was to big, if you lower that to e.g. 1uF you might see it
work better with STK500. But for e.g. BASCOM 10uF might work or with
e.g. Pnyprog, since it has longer delay for asking the signature.

Just some background on why you have the problem,

The MAX701 is way too expensive nowadays, the DS1813 Reset from
Dallas is much cheaper.
