Need help on the programmer PICKIT2

kenny90 · Oct 31, 2011

I program my PIC16f877a by using MPLAB IDE v 8.56. When program the PIC16f877a, it show that

Initializing PICkit 2 version 0.0.3.63
Found PICkit 2 - Operating System Version 2.32.0

how to solve the target power not detected and the unexpected device ID. Hope you guys can help me...

The "target power not detected" is not a problem--if you don't already have the pic hooked up to an external power source, it senses it and provides its own power. It's very convenient, if you ask me.

As for the unexpected device ID, it is just a warning, so it should still work. There are many possible causes of this error. I suggest you check and make sure that you have selected the PIC16F877a on MPLAB (not just the PIC16F877, or something like that). It simply means that the chip it sensed was not the one it was expecting.

The device with id 0x9A0 is a 16F877 not a 16F877A. It is revision A0 which was the first version issued so it's a very old chip but appears to be working. The config register is different on the two devices and so I don't think you can select the A version.

Thanks Mike! Very helpful! I was looking for a table just like that earlier.

The device with id 0x9A0 is a 16F877 not a 16F877A. It is revision A0 which was the first version issued so it's a very old chip but appears to be working. The config register is different on the two devices and so I don't think you can select the A version.

Mike.

Thanks Pommie, so when i create a project on MPLAB IDE v8.56 that time, i must choose PIC16f877, not the PIC16f877A right?
Thanks for the 16 series device IDs very much.

Pommie · Nov 1, 2011

Yes, select the chip you have.

It sounds like you are ready to write your own routines.

Good luck and have fun. If you get stuck then just ask here.

Mike.

The "target power not detected" is not a problem--if you don't already have the pic hooked up to an external power source, it senses it and provides its own power. It's very convenient, if you ask me.

As for the unexpected device ID, it is just a warning, so it should still work. There are many possible causes of this error. I suggest you check and make sure that you have selected the PIC16F877a on MPLAB (not just the PIC16F877, or something like that). It simply means that the chip it sensed was not the one it was expecting.

Thanks DerStrom8, so the Target power not detected and the unexpected deivice ID is just a warning and still can program the PIC16f877a right. and i have select the PIC16f877A on MPLAB when i program into it. and i have try a simple coding like blinking LED but than the LED did not blink .
so i have question:
1) did the coding program into the PIC16f877a? ( Although it show that program successfully)
2) how can i check whether the coding is program into it or not?

Well, as Pommie said, it looks like some of the configurations for the 877a are different from the 877, so it may or may not work. Make sure you select the chip you have in MPLAB and it should work.

1) It would help to see the code--It could be as simple as a test function that says something like if(x=y) instead of if(x==y).
2) You can read what is programmed into the chip using the PK2. Check that out and make sure it's right.

EDIT: Just found your latest post. Unfortunately i do not code in asm, so I cannot easily tell you if it's right or not. Try running the PK2 in debugger mode and see where it goes wrong.

House0Fwax · Nov 1, 2011

The first time your program calls 'Blink' it will be stuck there, it will never get as far as 'return'.

hi mvs sarma,

Blink ;LED blinking
movlw 0xff

movwf PORTB
nop ;the nop's make up the time taken by the goto
nop ;giving a square wave output
movlw 0x00

movwf PORTB ;set all bits off
goto Blink ;go back and do it again
return
END

the goto Blink is keep on blinking the LED and did not return back to the previous routine to perform call send.
am I right?

Hi, House0Fwax. in order to go to the 'return' routine, i must cancel off the 'goto Blink' right?
Blink ;LED blinking
movlw 0xff

movwf PORTB
nop ;the nop's make up the time taken by the goto
nop ;giving a square wave output
movlw 0x00

movwf PORTB ;set all bits off
return
END

your observation is correct.
you can define a counter to limit number of blinks, and if the number is reduced to zero, you should program , instead of go to blink it should skip and go to next line
ie RETURN.

That's right.
