'PROPIC problem'

Hello Friends
Some enquiries on the Propic programmer.
Some months ago I built the v2.5 programmer and downloaded the software
for it and everything worked fine. Since then I lost the software due to a
harddisk failure and recently downloaded the v3.9 software but alas my
programmer doesnt seem to work with it. Has anyone else had this
problem driving the v2.5 programmer with the v3.9 software or may it
be an elusive hardware fault of mine?
Thanks
Justin

pls check the hardware description. regarding the version
changes. the hardware was slightly starting from version number,
if you used the very old version and switched to newest software
this may be the problem

Hi! The hardware changes are partly documented in the
readme file that you get when you download the software
from
http://www.geocities.com/~oct_nogueira

Also I'm sure Octavio will give you any information that
you need, he's very helpful.

Greetings Pic guys,

I have built Octavio Nogura's Propic and am experiencing difficulties.
Propic will read without problems but refuses to write. When I try to
write it does not even get past the first byte. I have checked the circuit
thoroughly. I checked all the pins on the programming socket with an
oscilloscope to make sure that the voltages were correct. I have also
contacted Octavio but everything he suggested I had already done. I am
running Windows 3.1 on a 486 DX266.

I would appreciate help if anyone has travelled this route.

TIA

part 0 144 bytes
Please check the connection between the computer parallel port and the PIC progr
amer, especially the ground pins.
I hope this wold be helpful

I don't use propic(but I have the software), maybe you may try this:
1. make sure your parallel port is standart (SPP).
2. how do you know that propic can read? do you read the programmed device,
or just read the unprogrammed device (result is blank). I suggest the
programmed.
3. try to put pull-down on data pin RB7, result is 0 and try pull-up,
result should be FF. if this read test passed, you may say your hardware is
OK. :)
4. try to program using pull-down or pull up resistor (the buffer should be
FF for pull-up and 0 for pull down).
5. if it can read, I'm sure it can write because it uses the same pin. your
hardware is then OK.
6. try to program 16F84 first, because 84 uses 10ms, this is not critical
(compare with 100us for orher devices).
7. try to use different computer :(

goodluck
