that's interesting Mike, had a look at:
http://www.wbc-europe.com/hot/pcn/
but couldn't find a mention.

I'll cc this to sales@s..., he may know more and can get us up
to date.
Hope it's correct as I know many manufacturers went with this chip, and
were left up in the air.
No good alternative has surfaced yet.

BTW, I still have 9 x dt108's left.

Cheers Don...

Don:

Greetings from NC, USA, and thanks for the fine products and good service.
Those who have seen my finished circuits are very impressed by the motherboard
concept and the quality of the boards and say they look very professional.

1.  "FAT" simmsticks:  A current project is a circuit on the 1" DT201 with
28 pin IDS 1420.  For this kind of chip I definitely like to use a socket.
There is not much room left for the resistors and capacitors needed,
especially because I keep the leads short.

I am going to try mounting the socket and some components on what is
usually the solder side of the board, with busses under the chip for ground
and 5V.  Reasonably low components will be mounted on the front. This
I can mount the board in the last slot, and the fat part will not interfere.

2.  When I mount a socket in one of the "sea of holes"  boards, I still
have to make connections to other components.  Right now I am just
tacking the ends of the sockets, and bending the leads of resistors and
condensers from the hole they are in, and around the socket lead.  It is
kind of a wire-wrap type of connection that has been soldered.

Horizontal busses for the power and ground on the back of the board,
plus vertical traces on the front would make wiring a lot easier.  Do you
think we as a group can come up with a good design that you would be
willing to produce?

To all readers of this list who are using simmsticks, I would appreciate
your comments on the above.

Best regards,

fred

Hi Simon, first and foremost, sorry your first name slipped my memory. I
always try and use first names.
That's the trouble when you get to 60. :-)

thanks for the feedback, I hope it is correct, and I'll pass what you
have onto my members.
I know that you and so many others have counted on ST production of this
chip, and it would be good to see it back on line, and if it is, then I
guess it will be here to stay for some time.

Cheers Don...

I'll leave this for comments then.
I have had one or two others mention that similar boards would be nice.

I am still having problems programming the DT001/DT106 (16F877) board. I
have sucessfully programmed it a few times. I let a friend try it out on his
system and he programmed it. When he gave it back I could program it as
well, however only with P16PRO (PICALLW), not WinPicProg v1.9 by Nigel
Goodwin. I am suspecting the settings of the fuses. It seems it is sucessful
when I set it to 3D3A which is HS, and Background Debugger selected in
P16PRO. But the strange thing is I can set these same options in WinPicProg
and I don't get 3D3A. Sometimes when I read the PIC it comes back with a
different fuse and then I can't program it anymore.

Bascially I am wondering how to program the board with WinPicProg. What
should I select as the fuses? Is it normal that the two programs come up
with two different hex values even though I select the same settings? I am
thinking maybe this particular version 1.9 of WinPicProg doesn't work with
the board somehow. Also, how can I put the fuses in the hex file. The
programmers always complain that I don't have it encoded in my hex file. Any
suggestions are welcome.

OK Chris, I think the 84 will help to isolate the problem.
A good scope shouldn't load the crystal signals, but you don't need it
running to program the chips anyway.

I think Nigel is on this list, so he may respond. I haven't used
WinPicProg.

do you have a short cable, and do you have the latest version of p16pro?
Bojan is always updating it, and sorting out new bugs, which includes
speeds of modern CPU's with his delay settings.

You said in an earlier message you'd seen correct signals on pins - did you 
count the pulses off the CRO screen, and compare with the Microchip EEPROM 
Memory Programming Specification, document DS39025E? Checking pulses with 
the probe on the IC legs will confirm if your programmer hardware and 
software are working correctly together, whether the right volts and pulses 
are getting to the right pins at the right time. But probably requires a 
storage oscilloscope - if you're in Perth and you don't have access to one, 
email me direct, I do. The Microchip spec is available for download from 
their site, and also includes how to map ID, configuration, and EEPROM data 
memory bytes into your hex file:

User program is locations: 0x0000 to 0x1FFF (8K for 16F877)
4 ID words are locations: 0x2000 to 0x2003
Configuration word (fuses) is location: 0x2007
Data memory is locations: 0x2100 to 0x21FF (256 bytes for 16F877, one byte 
per address, LSB aligned)

Something that gave trouble when I first programmed on DT001/106 was the 5V 
supply to the PIC. This is switched on and off at high speed by the Propic 
software I was using. However, the voltage took a significant number of 
microseconds to ramp up to 5V, it had to charge the big supply capacitor 
C12 on the DT106 board. So the first few clock and data pulses had been and 
gone before the PIC was powered up properly, it wouldn't program. Removing 
C12 solved the problem.

Good luck,
Rob Moline

Hi,

You might get different readings back for the fuses as I mask the fuse
byte in WinPicProg before I display it - the fuse settings for different
processors use different bits, I mask off the ones which are not needed.

To add the fuse settings to your source file you can either add the
complete byte, like this:

list    P=16C84
include P16C84.inc
__config H'3FF9

Or set the fuses individually, like this:

list    P=16C84
include P16c84.inc
__CONFIG _XT_OSC & _WDT_OFF & _PWRTE_OFF & _CP_OFF

The individual fuse names are stored in the .inc file.

A couple of years ago I designed a SimmStick with a Xilinx XC9536 CPLD on 
it, as an entry for the 2000 SimmStick design competition. I never actually 
entered the design, as my prototype PCBs were the wrong thickness for the 
SimmStick connector, and I couldn't be bothered to fit it to a prototyping 
SimmStick, so it could fit the socket. I subsequently got some of the DT208 
SimmStick bus adaptor PCBs, and have just got around to fitting one of my 
prototype CPLD PCBs from two years ago to one of these.

The XC9536 has 36 macrocells with about 800 usable gates and up to 34 I/O 
pins. I'm using the 44-pin PLCC version. Max. clock rate is 100 MHz for the 
fastest version. Outputs can drive up to 24 mA.

The CPLD SimmStick has it's own clock input from an 8-pin DIL oscillator 
module connected to the GCK1 global clock input, and an LED/resistor 
connected to one of the I/Os. 16 of the I/Os are connected to D0-D15 on the 
SimmStick bus. There is a breadboarding area, and a JTAG connector for 
programming the CPLD via the standard Xilinx Parallel Cable III. Xilinx's 
free WebPack software is used for development; VHDL and schematic entry are 
supported.

At present, the CPLD SimmStick is ensconced in a home-made 3-slot SimmStick 
bus PCB, with a 1200 AVR SimmStick. I'll be putting a picture of it on my 
Geocities web page.

Some additional info.

I first tried with Netscape, that gave the

"The web page you are trying to access doesn't exist on Yahoo!
GeoCities. 
                                     
http://www.geocities.com/leon_heller/index_files/pu4geo.js " message.

When I tried with IE, the page loaded, but indicated that there were
errors. Things like 
"Line 43 Char 1 'document.all.yl0.style is not an object"
"Line 226 Char 1 object expected"

Andy, I just tried it on

http://www.geocities.com/leon_heller

with IE, and it worked fine. Perhaps there was a problem with 
Yahoo/Geocities. Pic isn't there yet.

BTW, I tried to contact you several times a few weeks ago, but you didn't 
return my calls. I wanted to discuss my MSP430 SimmStick with you.


Regards.

Hi Leon, I still have the same problem with your page.

I also sent you a message about my spam filters which I think caught
your hotamil address. (see sig and
http://www.dontronics.com/contact.html#bounce )

I added your individual address to my "white list" and have tested it as
working OK to me.

Sorry, I simply got fed up with spam and sites that promote them and
bodgy email addresses.
I got to the point of spending more time deleteing spam than reading
messages, so I have now blacklisted most of China and Korea ISP's.

Cheers Don...

Weird! I just checked it again, and it's OK. Geocities seems to be having 
some problems, as it gave me an error message once this morning, and it took 
ages to upload the pic. Details of the CPLD Simmstick are on:

Some of the problems with the URL I gave might be due to my bandwidth 
allocation at Geocities being exceeded. I've also put the files here:

http://www.leonheller.com/cpldsimm.html

I should have taken the picture at a lower resolution, the image file is a 
bit on the large size for downloading.

Can anyone supply programming/control/driver information (or links) for the 
Truly LCD display as sold by Dontronics? Or does it use the same control 
codes as the Hitachi HD44780, which always comes up in internet searches?

And what of the DT102 and DT106 wiring, having only 4 data lines going to 
the LCD? Is it possible to control the Truly LCD with 4 data lines, or do 
you need to connect up the other 4 data lines also?

Thanks in anticipation,
Rob Moline

Hi Rob,

I don't know if this will help you much, but most LCD panels based on the
Hitachi chip can be driven using a 4-wire data bus, instead of using all 8
wires.  You load the low and high nybbles into the LCD separately.

This didn't help me with my project as I only had 2 lines free so had to
use a shift register, but for some projects the 4-wire data bus means you
can control the whole LCD panel using one 8-bit I/O port.

Hope this helps,
Ben

FAQ:
Do you have specs on the LCD displays you sell?

Answer at:
http://www.dontronics.com/faq.html#lcd

This should give you enough info I hope Rob.

Most embarrassing...somehow I missed that link while searching your site 
for info. Will try harder next time ;-)

Hi,

I am working on a robotic device using three SIMMstick motor
controllers.  The device is battery operated and I want to conserve
battery power as much as possible.  I am using the PIC16F628 MCU and
would like to use the interrupts.  The idea I had was this, the mainline
program would set up the MCU and then go to sleep. When an interrupt
occurs (on RB4 or RB5) the MCU would wake up and bring RB0 or RB1 high
to power half of an H bridge to run the motor either forward or
reverse.  All or the porta lines are being used as inputs  for limit
switches or outputs to clear the flip-flops used to latch interrupts and
provide the interrupt for the next controller.  RB2, RB3, RB6 and RB7
are unused.  I don't have much experience with microcontrollers and no
experience using interrupts.  The hardware aspect is pretty simple but
the programming is kicking my butt. The external interrupt would come
from either the start switch or another MCU, the signal to stop the
motor is provided by external limit switches, and the final action
before returning from the interrupt would be to provide the interrupt
for the next MCU on the bus. After retuning the MCU would go back to
sleep mode.  I can find all kinds of examples for using timers to
provide interrupts to wake up a sleeping MCU but none to use the RB
change exclusively.  In this type of application do I need to save and
restore the context registers? I used porta for inputs and outputs to
avoid confusion and nested interrupts.  How does the the sleep function
work with an RB inerrupt? Does it still execute the next instruction or
does it go to the interrupt service routine?

Any assitance would be appreciated.

I've just designed a little 0.8" wide 20-pin DIL module (just over 1"
square) with a TSSOP MSP430F110 on it. It's a single-sided PCB with two wire
links, and can easily be made at home. I made the prototype in the kitchen.
To go with it there is a simple programming/test PCB the module can be
plugged into, that has a header for the FET, a power connector and an LED
connected to P1.0 on the module. The module has pads for a 32 kHz watch
crystal (I haven't mounted it yet).

You can see a pic of the prototype system here

        http://www.geocities.com/leon_heller/dil.jpg

It could be used to make an MSP430 SimmStick, by putting it on an
appropriate SimmStick prototyping board, or it could be mounted on my CPLD
SimmStick.
