pickkit_3 problems

[Hans van Veldhuizen]

Hello all,

I regularly have problems with the pickit-3.(MPlab X IPE v 5.45) .

  Because it happens less often when I first start up my PC, connect the pickit to the PIC and put voltage on it and only then connect the USB cable, this is my base.

  Despite this, I get often  messages that the voltage is insufficient, the PIC is not the right type or a wrong feedback occurs during programming. This can almost always be solved by restarting MPlab, or by first performing a read or an erase.

Lately I've been working with 3.3V. Now I had a program under 3.3V and that didn't work at all after programming without errors. After I erased the PIC separately below 5 V, the program works again.

I have two clones. One suddenly doesn't work at all under 3.3 V, but with the Pickit_minus (with modified firmware) on 5V.

Can anyone tell me where to look for the cause of all this?

regards

Hans

Hoi Hans

 

I have had the same problem with the PICKit3 and SNAP.

I solved the problem by both by starting the PIC first. It seems that the MPLAB IPE software looks by starting up for the PIC to recognize it.

Working this way MPLAB IPE recognize the PIC automatically.

You only have to ‘Connect’ the PICKit3 or SNAP.

 

Regards

Peter

Hello Peter,
I've tried a lot of tricks now, sometimes it works and sometimes it doesn't.
1. As you indicated start up with voltage on the pic.
2. Perform a read once.
3, Unplug the USB once and plug it back in.
4. Restart everything
etc etc. unfortunately it does not give a real solution.
regards
Hans

Hi

I don't have an answer but wonder if this setup  is a newer PC that is constantly automatically installing OS updates?

Just a thought to consider

( just saw a PC with WIN 11 "S mode"  and it frightened me  :)  )

Hi Hans,

I use two different PICKit3's. One that I use with the PICKitplus software and one with the MPLABX (IPE) software. 

As you know they use a different firmware in the PICkit3 and to prevent that I need to reload the firmware I just swap PICKit3's.

My normal approach is:

-) Start the PC with the PICKit3 connected to the PC

-) Power up the board with the PIC

-) Start PICKitplus or MPLABX IPE (also when using a SNAP programmer in combination with IPE).

I also noticed that when you start the PICKitplus software (not sure if that is also for the MPLABX IPE) and the board is not powered up that it still recognizes the PIC.

Some time ago I also programmed the PIC with the PICKitplus software when the PIC was powered with 3.3. Volt.

When connecting both a SNAP and a PICKit3, the MPLABX IPE software will recognize both and you can select which programmer to use. 

I never encountered the problems that you mention.

Kind regards,

Rob
