Redesigning PCB for ProPic 2 Gold

[zibby]

I'm redesigning PCB for ProPic 2 gold (once done I'll post it here, Eagle file) and I have few questions. Original schematic is using DB9 on PCB, and DB9-DB25 cable. I want to use DB25male connector instead, so I just want to make sure I have it right.
I got all pins except the one from 12c505 (pin # 5, marked as CLK VDD 8-8) it's connected to DB9 pin8, but what is it used for?
Is it connected to any pin in DB25?
Any help will be appreciated.

Thanks
Zibby.

**broken link removed**

pin8 is a handshake pin
and usualy is used to talk to the software or the port

Here's the pinouts for DB25:

Look at h***://***.geocities.com/mpu51

you will find propic2 there. but little changed. infact they are same(propic2 std). And also single side pcb.

it has db25 connector on pcb .
i learn how to connect propic2 db9 to computers db25 port.

Ok, let me rephrase my question. Original ProPic2 (and all mods) are connected to parallel port (printer port, LTPx), not serial port (COMx). Original schematic is using DB9 connector, with cable DB9 to DB25.
Original schematic has labels for DB9 and also parallel port DB25.
E.g. D4-5-4 where:
D4 is parallel port pin description
5 is DB25 pin
4 is DB9 pin

So I have question about pin9 (DB9) labeled CLK VDD8-8 connected to
PIC12C508 pin5. What is it used for, and what pin (DB25) is it connected to.
**broken link removed**

BTW, I did check out other schematics (read mods), but none of them are using 12C508.

Thanks.

So I have question about pin9 (DB9) labeled CLK VDD8-8 connected to
PIC12C508 pin5. What is it used for?

As far as I can tell CLK VDD8-8 is used to control VCC_VAR voltage.
This feature is only on ProPic Gold.
VCC_VAR is connected to VDD thru a tansistor switch in Gold version. In standard version VDD is just connected to 5V.

The variable voltage VCC_VAR is used to test the PIC at different voltagetes instead of only the standard 5V.
This is mostly intended for professional use, to verify that the PIC works at different operation voltages, for example 3.3V.
If you don't want this feature just connect emitter of T5 to 5V isntead of VVC_VAR and then you don't need the circut inside the dotted lines with PIC12C508 and LM358.

I have hex for 12c508 and want to use it with this programmer.
So because of that I want to make sure pin8 (db9) is connected to pin8 (db25)

Thanks.

propic 2

IT DOES !!!!!

ok..... i have built and used it
and originaly posted ppg2 in 1999 here

followed by the production grade programmer firmware for the 12c508a
rather that the orignal ppg2 this must be flashed to a pic508
it comes back to mind

the software for the propic pre xp is the only one that works
look here for alternatives

propic clone

http://www.enetsystems.com/~lorenzo/propic2/

here is a second clone uses some cmos to do the job of the pic
and a charge pump to do the psu arrangements

http://www.geocities.com/mpu51/propic/propic2.htm

maybe adding his additions to the epropic2 will be better
any views???



the software is all that matters to this design
use your hex the v2.9bla version of the software win 98 or me
fake licence {tip is copy the new ini fie back it contains the newer chips but you can buy it cheep 20 euros is only the price of a few meals.... and meals make projects but if you can find a way around the 100 byt limit cool///

and this design i put together then covers all chips and some avr and all senix via icprog
you can double varify looking at this guys pcb etc
if still not convinced

it is normal to connect an i/o to a lpt port direct so dont worry inside the lpt port controller is resistors to limit any current

propic2 clone

you re right. db9->pin8 connected to db25->pin8
db25 pins 2 3 4 5 6 7 10 have connections.

dont forget. before you insert a pic (target and 508) to programmer test it using propic2 XP software. watch leds and check voltages.

if there is a error you can see easily. then replace 508.

propic2 xp

ok here's in double sided PCB with schematic and BOM (Eagle PCB format, v4.09)

 

[Fragrance]

propic programmer

could it possible that you convert these file into pdf or any image file

because i do not have eagle 4.09

 

[zibby]

propic2 pcb

As requested pdf files.

 

[mbyka]

propic clone

see what you make of these


final verison
anyone want a pcb

or maybe some proteus practice is better
perhaps someone want to make for us pcbs for this design

i have hex files and will test this new design tomorrow after i make it on two single side pcbs that will stack
ill think of something

SEEMS THE XP AND PROPIC2 PROBLEM IS SOLVED

so this project will make a nice addition for basic langauges and also allow for lv flash etc etc.....

let me know if your building it please....

hi friend
can the programmer programming all pic series?(12..16...17...18 series)thanks

 

[ash]

propic ii schematic

could anyone send hex file?

 

[sick_man]

propic2 software

8) pcbs added to epropic2
ill put it back tomorrow

with corrected pcb layouts

design in brains topic above

The epropic can program any ic that picbasic supports
and some it dosnt

it can happily be used as an icp icd and isp as the propic also can be brocken out for this type of programming
by removing the board

for some strange chips {fpga plcc etc}

this requires making other sockets
i dont have the full layouts for

so we need a kind member to show us some adapters
so far i found a 40pin and 18 pin {inc eeprom and 24c serial stuff}

so pretty much covers a few
we need pic16ctype {long skinny 24pin } although if you look on there site
you get more of an idea but parts missing to make it dificult to ident the connections


help!!! hehe 8) 8)

Here is the hex file and asm file for pic12c509 for pro pic gold hope this will help you

zibby:
how does it work? your PIC12C508P have no input pin to activate voltage.

 

[Lodie]

propic schematic

Have constructed ProPic 2 on a redesinged PCB , Running the latest software (Unregistered) on the ProPic 2 Webpage on OS....XP and 2000.
When burning 16F84 all OK, but when READ Back the buffer displays all 0's. When the 16F84 is programed with ProPic 1 and readback on ProPic 2 all seems fine.
The problem seems to be with the burning action. Have verified PCB , Cables and setup, also the voltage test on the Software all test OK.
I requested help from ProPic 2 WebPage, but the responce was that the Software needs to be registered. The ProPic 2 Webpage state that the the software will work in a demo mode. In this mode you can program up to address 0x100.....Can the problem be the software ?
Thank you

If you use PROPIC hardware, try using ICPROG as the software.

It works fine.

Lodie...

I have had exactly the same problem whith my original hardware propic 2. PropicXP can read PIC's OK, but does not want to program them at all. I tried icprog and it worked.

Be aware that icprog 1.05C has a few problems with certain PIC's, including the 16F84. It *does* program them, but cannot read them back to verify! Use version 1.5 (no letter) if it supports your PIC, or use 1.05C to program and PropicXP to *verify* only if it is a problem PIC type.

Cheers,
FoxyRick.
