'PIC16F84 COM84 programming?'

Hi!

Is it possible to program PIC16F84 chips with COM84-programmer and PIP
software(http://sistudio.com/sistudio/download.html)? PIP 1.14 claims that
it can program 16F84.

The problem is that easiest PICs to get was 16F84 and I made COM84 to
program them. Programming don't write anything to the chips, but reading
seems to be OK. (code: 3fff 3fff.... eeprom: ff ff ff ff, I guess that
these are right for new PIC) Is the COM84 unable to program them or is my
COM84 just buggy?

no the driver is same, but you should select C84 as device I believe
let me know if it still does not work.

thee 3FFF FF reading does not indicate OK, it just indicates no data
it may be balnk chip or no chip.

I am doing the same thing and it works very well.

Be carefull though. 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
wasn't the case with the older version.

Your problem must be your programmer.

Good luck

Hi Antti

I see you have just replied too.

When I program F84's I select 16F84 as the device & it works fine!

Cheers

Sorry if this is a repost but I got an 'Undeliverable' message with the
first one.

I am using the same combination of hardware & software.
I choose 16F84 as the device and it programs perfectly every time.

Be carefull though. 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
wasn't the case with the older version.
