pickit 2 with 16f628a debug problem

[zhaniko93]

I have pickit 2 and I program 16f628a with it well but when I tried debugging, it says:
"Found PICkit 2 - Operating System Version 2.32.0
PICkit 2 Unit ID = OlHoss
Target power not detected - Powering from PICkit 2 ( 5.00V)
PKWarn0003: Unexpected device ID: Please verify that a PIC16F628A is correctly installed in the application. (Expected ID = 0x1120, ID Read = 0x1060)
PICkit 2 Ready"

And when I try to debugm it says:
"PKWarn0006: The local copy of program memory has been changed since the last program operation. Should PICkit 2 program the target (fix) before proceeding?
Programming Target (7/17/2011 11:59:10 AM)
PKWarn0003: Unexpected device ID: Please verify that a PIC16F628A is correctly installed in the application. (Expected ID = 0x1120, ID Read = 0x1060)

PICkit 2 Ready
"
And alert: "PK2Error0028: Unable to enter debug mode"

I connect pickit 2 directly to breadboard, and on breadboard is nothing else 16f628.
After searching a bit, I found that for debugging:
PIC16F627A*, 628A*, 648A*
- Use AC162053 ICD header & AC164110 adapter.

Do I need it in addition? ca anyone give circuit to build it's clone or something like that?

Actually I have junebug, and can I debug 16f628a without any additional things or not?

Hi,

If you go into MPlab , Configure and Select Device it tell you straight away if the chip you select will run on the Pickit2 in Debugging mode and if any header are needed - see the box at the bottom right hand side.

For the 628 /A you do need a header.

Basically they are a Pic chip capable of running debugger directly, it then controls your target chip.

Its probably much easier and cheaper to use a chip with Debugger built in.

Have a look at the 16F88 which is, I believe pin compatible with the 628 but with more memory and features.

Hi,

See this thread - basically the same applies as my last post https://www.electro-tech-online.com/threads/using-mplab-junebug-icsp-to-debug.91747/

I second switching to the 16F88.

OK I understood, everything is clear now, thanks

You can debug the chip on the junebug. If you want or get a 16f88 like they said

Do you like the junebug ?

You can debug the chip on the junebug.

You still need the adapter for the 16F628a.

I was just saying if he wanted to debug a chip use the one on the junebug it's debugable
