Posting.
as I will be away for a few days, I have changed the flags so anyone can
post. This also means you may receive spam.

Biggest problem seems to be users that have multiple addresses that they
post with.

Anyone want to be a group moderator?

If we decide to use a simm-product inside another,
how does one get 30p simm connectors? Molex no 
longer shows one in its catalog, and AMP is phasing
their version out. 

Anybody know other connectors who HAVE connectors?

Hi all,

Is there an arhive of this list somewhere? If somebody told it and I missed it
sorry...

Cheers,
Mert

Hello Mike Parkin,

Are you talking about the programming software by Brian Lane?
I downloaded it a long time ago and compiled it under RedHat Linux with
the 2.0 kernel and libraries and now it core dumps if I run it under
latest version of RedHat.

There was mention of this recently on the piclist at mitvma.mit.edu list
server.  I archived a message from Byron A. Jeff (byron@c...)
and the changes he made.  I have NOT got around to hacking the source
yet to fix it being rather new to PICmicros.

Please keep me in the loop if you find a better answer to getting it to
work.  As I get up to speed on learning this stuff I want to convert to
Linux for all steps of the process.

regards,

// David //

David,

Thanks for the message. Is there a listserver archive for mitvma.mit.edu?
If so can you point me to it? 
Or can you send me the message from Byron A. James that showed the changes
he made?

Thanks again ,

Mike

Hi PICsters,
I have a question regarding the RETLW instruction. I am trying to update
some code and find myself battling with the following code example that uses
RETLW. Could someone please explain how this code/instruction works. Please
advise. Many thanks.

Hi PICsters,
Can someone please help me to crack this code. The 'stumper' is the RETLW
instruction which as I see it returns from somewhere with a value in the W
reg. Please advise.

John,

<RETLW lit> instruction causes a return from a subroutine and also PUt
a literval value into W.  So it performs 1 pop from the stack and
loads that value into program counter, and transfer the value "lit"
into W.

It is widely use to implement data lookup table. For example in your
attached code:

>                rrf     PortA,w
>                andlw   00000111b               ; switch on Row Index
the instruction above bound the table size, so it would go
out-of-bound

>                addwf   ProgramCounter,f
the routine returns the lookup value of f, in this case:
0=< f <= 4, value = 0
f = 5, value = 6
f = 6, value = 12
f = 7, value = 8

>                retlw   0
>                retlw   0
>                retlw   0
>                retlw   0
>                retlw   0
>                retlw   6

Mike,

I ran into the same problem recently - only not with a simmstick. I got
PIC16F84 Starter Package from phanderson.com, downloaded P16PRO from
http://www.geocities.com/SiliconValley/Peaks/9620/ and got exactly the
same symptoms - programming light always on, verify errors and the PIC
was always 3FFF. 

I had the hardware settings wrong. In P16PRO I had to go into SETTINGS,
HARDWARE and set VPP to <neg>. Problem solved - programs like a champ. I
hope this helps.

Thanks,
Archie

Archie.

Thanks for the help. My problem was an assebly problem. Somehow I got the
transistor shorted so the  VPP light was  on. I replaced the transistor
and now its works great!. 

My next task is getting picprg2.2 to work with the 2.2.x Linux Kernel. 

It looks like I have this working but I need to test it a little more
before I commit to saying it is working. 


Again, Thanks for the help!

Hi,
I'm very new to this and I haven't been able to figure out which
connector on the
simstick (dt101) i should connect the 5 volts.... I've tried lots of
difrent ways but nothing works.
Is "Digital gnd" only the ground for the IO pins?

//Marcus Agbrant

Gday Marcus,

> I'm very new to this and I haven't been able to figure out which

> difrent ways but nothing works.

I am not quite sure exactly what your question here is so I will offer some
input that hopefully gets you to where you want to go.

The DT101 has its own onboard regulator (78L05) you will note on the cct
diagram that there is a 5 volt isolation link (J1) this is incase your
motherboard (ie. DT001) has its own power sorce then you will need to have
this link OUT (there is a track to cut... on the solder side of the PCB
between the 2 pads of J1) as the two 5volt supplies would `fight' with each
other.

i.e. ONLY use ONE power source, (DT001 or DT101 onboard)

If you are using the DT101 as your power source you should place the input
power source onto the PWR connection (pin 4) of the simmbus and GND to the GND
pin (pin 9). If your regulator is working you should be able to see 5 volts at
the 5volt pin (pin 7) of the simmbus.
NOTE you will of course need J1 inplcae (or the track not cut) if you wish to
use the DT101 for the power supply, also the PWR input should be DC not AC so
check your power source (a good one to use is a 9 volt battery here).

If on the other hand you are using the DT101 in the mainboard (ie DT001) the
cut the track under J1 and remove the link if there is one fitted and the
DT001 will supply the 5 volt (as measured at pin 7) for you.

I hope the above is helpful.



> Is "Digital gnd" only the ground for the IO pins?

Where did you get that term from? I cant find any reference on Dons over lay
or schematic (but then I am blind sometimes)
But in answer No! it is GND and common to all GNDs (sometimes you need to be
careful with ANALOG GNDs but still these generally still connect to the common
gnd (usually at one place only)

check out the following page

I have just re-read your msg and you need to connect the power source (still DC of
7-10 volts) to J2 which is located along the top edge just top the left of the
78L05 with + to the left (square) pad and - to the right (round pad)

Hi Everybody,
I am not a design engineer and have newly embarked in the Simmstick world.
I have my sim100 with the AT90S8535 AVR chip mounted on board.I am using a 
8M xtal.I have programmed my AVR using Meng's BA1FB from my PC printer port 
connected to J3 on my sim100.I have written some programs (blinking and 
walking LEDS and read switch) to test the I/O ports of the AVR and they work 
perfectly.
Now I wish to run programs in which results need to be displayed on my 
PC.For example printing some values or reading the A/D values from the ports 
of the AVR.
Can anybody help me concerning the codes and connections required from my 
sim100 to my PC?
Please.I urgently need your help!!!!

Thanks.
Salim.

Mick, I know the screen print on the DT101 leaves a lot to be 
desired. but from what I can make out by tracing the pcb tracks is 
that the 3 pin device which is to the right of J2, and above C4 is the 
Brownout chip, the device to the left of J1 and to the right of C7 is 
the 78L05 Vreg. I have to admit that I am unsure about this, which is 
why I have not finished building the board yet.

Mick, I'm not sure but..I'm building my first DT101 at the moment 
and from what I can make out from the track layout J2 is  to the left 
of Brownout. The Vreg is to the left of J1. I wish there was a clear 
screen print of one of these devices as I'm really not sure about this, 
and I'm not going to fit the Vreg and Brownout until I am.
totally different topic perhaps you can help..
how do you answer a thread in the digest version of this list without 
massive cutting /pasting and messing about , as I have done with 
this reply..

Never underestimate the power of Human stupidity

My 2 cents worth of explanation : )

I have built the DT001 programmer and a DT101 simmstick.
Have it all up and working now flashing pretty LED's.
So, My mistakes first put a 78LO5 regulator on the DT101, this got nice and
hot in competition with the 7805 reg. on the DT001, also caused the VDD
light on when in program (although did program).
Don't fit the 78LO5, the DT101 gets +5 from the DT001. If you want to power
the DT101 outside the programmer, fit the reg and apply power to the pads
(looking from component side) directly above C3 (xtal cappy) +ve left, gnd
right.
Second mistake, not fitting all the resistors (5 * 10k), so didn't have the
MCLR pin tied high, wondered why it was locking up.

Hope this is of any assistance to anyone.

Brian.

Greetings;

I have two questions for the group niether of which pertain to
simmsticks.

Question 1)
What is the 'subscribe' address for the PICLIST?

Question b)
Using MPLAB v4.0 and whatever version of mpasm that comes with it, 
I would like to write functions and generate object files and link 
them together like the higher level languages do. Save all the 
hassle of wrestling with code and what not. The README & Help files 
give ample enough explanation regarding the source files, but the 
linker part is pretty vague.

Can someone please email me a copy of an example linker file that
provides enough info to figure out what is going on?  Have been
messing around with powerpc linker scripts at school so understand
*a little* of what to look for.

Thank you;

ok..jef

Subject: [simmstick] PICLIST and linker question


Greetings;

I have two questions for the group niether of which pertain to
simmsticks.

Question 1)
What is the 'subscribe' address for the PICLIST?

Question b)
Using MPLAB v4.0 and whatever version of mpasm that comes with it, 
I would like to write functions and generate object files and link 
them together like the higher level languages do. Save all the 
hassle of wrestling with code and what not. The README & Help files 
give ample enough explanation regarding the source files, but the 
linker part is pretty vague.

Can someone please email me a copy of an example linker file that
provides enough info to figure out what is going on?  Have been
messing around with powerpc linker scripts at school so understand
*a little* of what to look for.

Thank you;

ok..jef

Hi there Mike (nice name),

Please accept my appologies, You are quite correct, the Vreg is just to the
right ofC7/C8 and its the brownout that is to the right of  J2. Have a look at
DOns (ok its not a fantastic overlay but it is there) overlay at :

http://www.dontronics.com/dt101.html

IMHO Dons overlays have improved since that one and when I see him today I
will suggest that he `cleans' it up a bit.

Sorry cant answer that one.

Hello

I have problem to start pic002 in bs2 mode
Can i connetc pi002  straight on DT003 and max232 will do serial driver
work or not
or i need to install the transistors on pic002?
do i need install bc547 for ATN signal on DT003
ok I got messages Dowloading(to half bar)then communication error
2 communication erreor
3 hardware not found
Colud you help me little a bit

Cheers Tanel

Hi Tanel,
Robert Nansel did a complete writeup on this in Nuts & Volts magazine,
however Kalle Pihlajasaari also did a step by step description at:
http://www.dontronics.com/ssconfig.html#bs2
I hope this helps.

re transistors, don't install them if you have the max-232 installed.

For those that don't know, Tanel lives in Tallin Estonia and knows Antti
Lukats, who was the original designer of SimmStick and PIC002. think you
can hunt him down Tanel? :-)

We are about to finalize our runAVR (rAVeR) board, and felt the
SimmStick users may like some input.
you can check it out at:
http://www.dontronics.com/dt006.html

As always, just after we release a new board, we get some one say "why
didn't you do this or that?"
Here is your opportunity.

Hi All,
	I'm just starting with PIC16F64 
Could someone give me some  'basic' do's and dont's and "lore" in 
the use of these Beasties B4 I start burning.
 Is there an FAQ for Hardware interfacing ? covering simple things 
like protecting the I/O pins from sinking/sourcing too much current 
etc.
 final queries for today.;-)
 the DT101 brownout cct.. I don't have one of these beasts, would 
the following be ok..component designation as per DT101..
R1=10k paralleled with 1n4148 to vdd, R2= 330r, and 0.1uF between 
junction of R1/R2 to vcc. values approximated from DS30430c page 
43.
 I have a 24C02-MB in SO package, will this replace the 24LCxx 
eeprom as specified..if used in an SO to DIP carrier?.

In return for your words of wisdom I offer two URL's that I hope you 
will find interesting.

www.tech-tools.com
ftp.tech-tools.com
for Latest version of Parallax assembler, now called CVASM16, and 
some interesting, to me at least, programs and projects.

www.cs.unibo.it/~lanconel  ( thats a curly? not a minus )
for "Ponyprog" a simple RS232 based programmer for a multitude of 
devices, I2c, PIC, SPE, Microwire, AVR etc.  CCT and Program 
there. your comments appreciated on this.

many thanks.. Mike W

As no one has answered, I'll pop in here Mike.
the best source of info for this sort of info is the piclist and its
archives.
Andy warren's page (on my links page) has a lot of info on this, however
another good source is piclist.com put together by James Newton.

You will possibly find that just R1/R2 combo will do it, however the
other items should help.
The 64 of course is one of the older family members, and may need a B/O.

If it is a microchip part, yes, it should be OK. newer parts like the 64
(not 65), have slightly different r/w routines.

My apologies, I just stated that piclist.com was by James Newton, then
found this:
This FAQ maintained by Jory Bell, Mark Willis and James Newton. Last
update 200001100717 
Sorry Jory and Mark.

Gee, that's a big date.
