Hi

Last night I used my Dual Power Eprom Programmer to program a PIC:

This was my first shot. I never programmed a PIC before, only Eproms.
Anyway, before I tried to program it, I read the PIC contents without problems.
Then I loaded the HEX file, and clicked on the Program Chip button, but all I got was a "Error writing program area":


What I did was to set up the switches as shown on the image, put the PIC in the "PIC" socket, and go.

Am I missing something?

Questions:

1.- I have some NMOS EPROMs programmed before I started platying with the PIC. Does the Vpp I used for those EPROMs affect to the PIC programming? What value should I use for PIC programming?
2.- I have a "data-switch" between my programmer and my PC parallel port. Does this affect to the PIC programming? Should I avoid the "data-switch" and connect the programmer directly to the PC parallel port?
3.- Is the PIC (shown in the picture) placed at the right socket?

Help!

PS: Reading the PIC and 'blank-testing'-it run OK. Only the programming fails...No copy protection selected, the PIC was brand new...

OK Thanks for your response.

So basically I fried my PIC using the wrong programming voltage...

Yes, 12.5 Vpp the right voltage.

Bump.

I just see your first picture of programmer, the Vpp voltage setting is wrong. The right side of jumper need to short the lower 2 pins. Not the upper two pins.



Hi

I updated the picture (please refresh), to show where the Vpp jumpers (JP5, JP6) are located.



If I short the lower 2 pins of JP6 ("the right side of the jumper"), given that the upper 2 pins of JP5 are connected, then I'll get 12.5 Vpp, according to the User Guide:



Is this correct?

BTW, I should have asked before: is 12.5 Vpp the right voltage for programming a 12C509A Microchip PIC?

Yes. You need select "Willerpro Programmer".
Also, if you are using Windows 2000 or WindowsXP, you need go to the Optons->Misc->Enable NT/2000/XP driver need checked.

OK

I downloaded ICProg, then went to the Hardware Setting menu (F3).
What programmer on the list should I select?
"WILLERPRO Programmer"?

Try ICprpg software.
