Pickit 2 VPP Voltage Level error

[nachum]

Hi
I bought a MINI KIT2 for programming. But when I try to program I get a message on the voltage level on VPP is lower than that message "Pickit 2 VPP Voltage Level error. Check target and retry operation." . Any idea what could be done to resolve the problem.
I checked with a FLUKE the VPP showed me just 1+- volt.

Attached pictures of programmer And the development board kit.

Thank you for your help

Hi,

Not familiar with that dev board, but it looks like a far east Pickit2 clone.

I would first prove that the Mini Kit2 was working ok by simply putting your 16F chip in a breadboard etc and connecting short 5 wires to the programmer and first see if it can recognise the chip and then program.

The results of that should show what the next step is.

Thanks for the answer.
What connections should I do ?
i work whit pic16f877a

 

[blueroomelectronics]

The PICKit2 software has self test modes. Quite useful.

Hi,

You should connect the two -

16F877a.......................Pickit2

pin 1 VPP .......................1
pin 32 & 11 + Vss ......... 2
pin 31 & 12 - Gnd ..........3
pin 40 Data.....................4
pin 39 Clock ...................5

kit2 pin 6 not used , see the Microchip Pickit2 Help - User Manual for helpful info and trouble shooting is this does not work.

Hi
I connected the micro to the PICKIT 2.
Like you said
pin 1 VPP .......................1
pin 32 & 11 + Vss ......... 2
pin 31 & 12 - Gnd ..........3
pin 40 Data.....................4
pin 39 Clock ...................5
I check with PICkit 2 v2.61 and i Received "Pickit 2 VPP Voltage Level error. Check target and retry operation"

Hi,

Just need to establish some facts.

The 16F877, did that come preprogrammed with some sample led flashing progam for the dev board, if so, did it work on the dev board OK ? - Does it still work on the dev board ok ?

Your first attempt to program was with the 16F in the dev board zip socket and the minkkit2 plugged into the dev board ?

The attempt you have just done was in a breadboard with nothing else connected to the 16F and the wires between the two not longer that 150mm / 6" ?

Do you have any other pic chips to hand ?

Test the pickit2 with it's software it has tools to test the programmer with like Bill said. If all good with your pickit2 then make sure you don't have Vpp
pulled low it should be pulled to Vdd with a 10k resistor

 

[nachum]

I bought a development kit + programmer (PICKIT2).
Right now I could not do anything.
I always get an error message on the problem of voltage VPP.
I downloaded the software that checks voltage programmer. And there I get no voltage on VPP.
There could be a problem with the programmer or I did not connect properly??

 

[Vizier87]

I checked with a FLUKE the VPP showed me just 1+- volt.

You're sure? That is the problem then, USB output for Vpp to GND is around 5V. Check that from the USB output of your PC (it is USB connected ain't it?) according to this:
**broken link removed**

Figure out the problem from that point, USB ain't gonna be the problem, probably some short-circuit problems you overlooked.

 

[nachum]

USB properly. the VDD shows 5v.
But when I try to Check Communication i get an error message on VPP.
I attached pictures.

Hi,

If your last Vpp test was done with nothing connected to your Mini Kit2, and the Vdd looks ok, then it would seem you have a faulty unit and it needs returning to your supplier.
Is it a far east mail order unit ?

Internally they are smd devices and little you can do to them.

The reason I asked earlier about if you had run any demo on the dev board was to try and establish if that board was also ok, particularly the connections to pin1 the Mclre / Vpp pin.

 

[nachum]

I checked the PICKIT 2 even without the development kit also received an error message on the VPP
I bought the programmer in China
If I did not connect the pic16f877a to PICKIT 2 Which result I should get When I check the VPP ??

 

[Wp100]

Hi,

The Troubleshooting via the Pickit2 program must be intially done, as the opening screen states, with nothing connected to it other than your test meter wires.

So with the Minikit2 plugged into the usb lead and the output connector totally empty, connect your meter + lead to Vpp pin 1 and your meter - lead to pin 3 - your meter should be set to the dc volts range.

Do you get anything near 12v being shown ?

Also try the +5v Vdd again.

 

[nachum]

I do not see any change in VPP When I checking with FLUKE.
vdd=5v
vpp=0v

 

[Wp100]

Hi,

Well even if you test it without the Fluke connected it should still show 12v on the diagnostic screen - looks like you have been unlucky and got a duff one.

Back to the suppliers then...

 

[colin55]

Vpp will not appear if a chip is not recognised by the programmer and will not appear until the actual time of "burning."

 

[nachum]

Hi

How do I see 11+ volts? the USB is 5 volts.
I get an error vpp

 

[nachum]

I tried to burn and i receive notification problem on VPP.
So I installed the software PICkit 2 v2.61 and saw that PICKIT 2 volts on VPP.

 

[nachum]

Could be that the PICKIT not know to program the PIC16F877??
