PICKIT 3 problems

[hans]

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

As the real developer of PICKitPlus and the database that was plagiarized by PK- I am the right person to help.

When our database was copied the developer decided to change the order that the chip families are searched.  I wrote a detailed analysis for him and he ignored. So, using PK- can apply the incorrect voltage your PCB during startup.

Which chip or chips have this issue?  This will help me isolate the issue.

Hi Evan,

I noticed indeed issues with PICkitminus that it sometimes recognizes another PIC than the one that is installed.

So in order to get rid of this - and other issues I encountered - I just ordered your PICKitPlus software for my PICKit3 🙂.

Kind regards,

Rob

Just sent the order go through the process.

If you have issues, then, we can set about resolving for you and the greater community.  The new release has the new 16F180xx and 16F171xx chipfamily - we are waiting on the  16F181xx to arrive before we can add (as we have to test them!).  Also, adding more PIC32Mxs at the moment.  Always busy.

Hi Evan,

Downloaded, installed it and it work for my PIC16F18857 (also programmed a PIC 12F675 and works OK).

I still get the error on the PIC16F18857 that it is not able to program address 0x0000 (verification error) but I think the PIC died so not related to the PICKit3 software. I will try with a fresh version.

Thanks for the quick service.

Kind regards,

Rob

A  PIC16F18857  is that same architecture as the other  PIC16F188xx chip family.  Send me the hex.  Let us inspect the HEX to ensure the hex works here.  Use the email address in your distribution email.

Rob, prior to throwing it away, plug it in a stanium foil for a while to short all pins together.

Old PIC12F675 had this problem with address 0 and this was in a surprising way the cure.

Of course, only if you did not supply it at 220V, see the top right corner...

I had the same annoying problems with an 18F4520. Sometimes yes, sometimes not, then again a non-working program !!
Luckily I still have my old wisp. Connected and everything works flawlessly, just like before

. If something didn't work for me in the past, I was sure it was my fault. !!!
Wouldn't Wouter be able to expand his wisp so that it can also handle the newer things?

 Otherwise I think I'll just use pics that the wisp supports. There's plenty of fun to do with that.

These issues are typically very simple to resolve.  I have test rigs that cover about 1300 PICs and therefore we can replicate issues very quickly.

We can always help to verify an issue.
