Hello,
yes, i'd built it in 1 hour and it works fine! You can use windows or dos
software, both of them very friendly. However, I think that it doesn't
support in circuit programming, that is, connecting the pic circuito to the
programmer pcb by a cable. That's what I'm trying to do now with other
programmers.
I have a programmer that is almost the same as the ludipipo Pic Programmer and
it works
perfect. If you like i can send you the schematic and the software to program
various
eprom's and Pic procs.

PTM: I made a new drawing of it with HiWire, smaller and with connection
for 24Cxx I2C EEPROMs: http://ptm2.cc.utu.fi/ftp/pub/assemble/pcb/ludi1.dwg. Ludi2 is even
smaller but I have not tested it.
It works just fine, if you work with a PC that has 1488/1499 RS232 port.
It seems that some RS232 drivers don't give voltage enough for LUDIPIPO.
With my Compaq Aero I have to program everything twice.

PTM It could be done, if you make a connector to your pcb and another to
Ludi. There is nothing in Ludi or in the programs against it.

Hello Rod
Don't know about Ludipipo.
A few months ago, I asked in this group if a simple in-circuit
programmer
might not be as good as buying Microchip's programmer.
You will find a reply below. I built that programmer and had no
problems. In-circuit programming works without having to disable
the clock (see below). I recommend it. You will find the progr.
software at:
If you later want to be able to program _any_ other PIC-procesor, you
might build Octavio Noguerieras parallell port programmer, which
is much more complicated, but not only programs the whole range,
but also checks programming at different supply voltages, really
necessary only for production programming. Also for
in-circuit programming, but a disadvantage is that it seems to
be necessary to stop the clock from running by grounding
CLKIN.
Works very nicely under Win95. It's at:
Both work well with MPLAB assembler-editor-simulator, that you can
download from http://www.microchip.com
Check the include files included (!) in MPLAB.
You can specify the config bits like this:
list p=16c84
#include p16c84.inc
__config _xt_osc & _wdt_off & _pwrte_on & _cp_off

Hello Gustaf
Your approach is the best way to go. I have been operating that way for
a
year now. I have several production units running & I program them all
using a simple serial port controlled programmer.
I use the reprogrammable 16F84. This is the easiest chip to use as you
can
erase it in circuit. There is nothing that you can program with the
MicroChip programmer that you cannot program with the many serial
programmers available.
I would suggest that you use a program called PIP02 as a programmer. It
is
dos based but runs under windows. It is faster than other serial
programmers I have used. My actual programmer consists of a serial cable
and 3 resistors!
I got the diagram (that I modified slightly) from Com84.zip. I can't
remember where I got it from, but it is only 16K so I can send it to you
if
you want it. The PIP02 programmer is available from many sites but it
originates from Silicon Studio. There are currently two versions I use.
The
one is v1.04 & the other 1.14. The older version doesnt support the F84.
The newer one does but it has a small bug in it in that it doesn't close
the hex file once it has loaded it. This prevents you from keeping the
programmer running (Under windows) while you are trying to use Mplab to
assemble.
Cheers
Dennis
___________________________________________________________
Here is a diagram of the changes I made to the Com84 programmer. I have
been using it for a year on a 120 Meg Pentium without problems. (If you
can't make out the circuit then cut it out & paste it into notebook)
I like this programmer because I usually have other things plugged into
my
parallel ports.
Don't give up hope. I started in Pics trying to use a Parallel
programmer
and had all sorts of problems. That's why I now use a serial programmer.
PIP02 works very well but be careful. V1.14 has some bugs. One is that
the
configuration bits
are not picked up from your hex file correctly and the other is you
cannot
compile in MPLAB (Under windows) if you have PIP02 V1.14 open in another
window. PIP02 doesn't close the hex file so MPLAB cannot access it. This
It works fine, if the serial port can deliver enough volts. I use it in
preference to one of the parallel port programmers I've built because I
prefer the programming software.
>>Has anyone on the list built the LUDIPIPO PIC Programmer

I've built the Jens Madsen modified Ludi RS232 programmer (11 parts )and it
works fine on my old 586/133 with the Pixxer software under dos but not so
happy under Windoze95.

Excellent for a match box sized unit, for programming only (without the
hassels of needing a psu), but for prototype development, may I suggest any
variation of the David Tate parallel port unit, as its easier to analyse
and easier to program in cct. See comment below.

I also couldn't connect up my RS232 unit to program in-circuit due to the
voltage offsets, I'm not saying it can't be done, just that I preffered to
use the David Tate parallel port circuit. This is now working just the way
I want it to. I use a 14053 analog mux on RB6 and RB7 (the programming
pins) so all 16C84 I/O pins are available for use in any development
circuit.I download the program (assembled C source) to the circuit under
development while the 16C84 is running. Everything stops for a couple of
seconds and then the new program takes over, no switches to set or chips to
swap, it all happens from the pc keyboard.

Hi Pasi!I have tried to look at your drawings with HiWire II v2.2r0 but
no chance, the editor refused to open them. Do you have any idea why?
Thanks Gaston.

PTM: I had some troubles with older HiWire versions, but dont know why. I
Try to make a PS version of the pictures.

PTM: It seems that this version of HiWire that I'm using is rather old,
V1.1r11. Sorry .
