PIC16F84A and PICKit2

[apple737]

Does anyone know how to troubleshoot this? I havent got a reply for a long time.... =(

Hello there,

Is there other alternatives of using the PIC16F84A? Or, have you followed the link I gave you previously? The old microcontorller is a bit difficult to be programmed.

Nope, i really need this PIC16F84 for my circuit board to work.

Sorry, i havent try...

in case anyone else has trouble with the pic16f84a and pickit 2 with low pin count demo board, here is how the pins match up.
all you need are those five from pickit 2 to the chip and you're ready to go

PICKIT 2 PINS PIC16F84A PINS
1 (13+V) 4 (mclr)
2 (5+v) 14 (Vdd)
3 (GROUND) 5 (Vss)
4 (PGD) 13 (RB7/PGD)
5 (PGC) 12 (RB6/PGC)

Does this mean i disconnect my PIC16F84 from the program board? Instead of program it in the programmable board, i connect it through breadboard and connect as above u have mention?

Btw, where is PGD and PGC? I cant find it on my PICKIT2 PINS.

According to the Low Pin Count demo board manual, PIC16F84(A) is not supported. You have to put it in the breadboard and connect them manually.

The PGD and PGC pins can be found on the Pickit2 pins. Please consult the manual for the programmer. It's located in the Pickit 2 software -> Help -> Pickit 2 User's Guide, page 9.

We are using UIC00B to program PIC16F84A on SK18B without problem. But PIC16F84 does not seem to be supported by PICkit 2 nor MPLAB IDE. We do not have any PIC16F84 in our lab to verify this.

Sometime I see PIC16F84A in your post, but sometime is PIC16F84, which is the correct model you want to program?

Thanks Brian. I have tried using your method to program but i still failed to program it into my PIC.

Then, probably this might be the cause. Currenly i'm using PIC16F84 not PIC16F84A. Btw, what's the different between these two PIC? I understand that PIC16F84 is an older version and the PIC16F84A is a newer version. If i were to load my program into PIC16F84A, is that possible?

[Brian Griffin]

If I'm not mistaken, the PIC16F84 has no 'tag' inside for in circuit serial programming (ICSP), and therefore PICKit 2 may not able to detect it.

Please take a look at this Microchip forum thread.

Ok, Thanks Brian for telling me. Maybe i would order the PIC16F84A to try out.

Sich, the forum is about PIC16F84A. I need more information on how to use PIC16F84 and Pickit2.

Have anyone in Cytron forum tried to modified the PK2DeviceFile.dat file to switch compability from PIC16F84A to PIC16F84? Just wondering if anyone have slight idea about it.

Owh...i thought you are using 16F84A since your title stated it. Haha. Sorry about it!
