I bought a PK3 some months ago & used it to programme a 16F1708 via MPLAB 8.92.
(I have MPLABX but have not worked out how the use it fully & did not want to waste time climbing the learning curve). 8.92 does all I want.

However, the programming software I have used for years (WINPIC) does not include the 16F1708. So I had to buy the PK3

Yesterday, I tried to use PK3 again to do another 16F1708 and received the "Target device ID (0x0) does not match ......0" message.
I connected my scope to the Vpp (without the PIC installed) and found it was only 4.4 Volt rather than the required 8 ~ 9 Volt. I checked the hardware and it was OK.
I also tried to programme a 12F675 but received the same message.

It would be excellent if someone knows how to enter the 16F1708 into WINPIC.

Any advice will be appreciated.

Hey larny, you ok?

are you using "power from device" or a separate PSU?

I have found my PK3 has trouble providing the target VCC

It is annoying sometimes, I go through a load of PICs (I still use the smaller ones for some projects with a mix of GCBasic+ASM) and I can go back to it after a couple of months and nothing works - mystery and I have to piddle around to get it all working again.

Hi,

I have the same feelings as you over WinPic, but time moves on and I have to get used to the current state of things. It usually means making some sort of adaptor to connect the PicKit3 to the chip.

I have had similar occurences with Pickit3 and have solved them by using the 5v supply from a usb serial connector like the CP2102.

I have not studied this completely, but this website seems very helpful https://www.northernsoftware.com/dev/pic16f/pic16f1708.htm

May be worth a visit.

Thanks CaptainBoing. I supply the target from one of the PC's USB sockets.
Looks like I'll have to keep piddling around in order to solve it.

Thanks Trevorc. I made a PIC programmer/adapter for programming the 8, 14 & 20 pin PICs. See attachment. I supply the 5 Volt from one of the PC's USB sockets.
I'll have a look at the link you gave me & report back.

EDIT. The ICs are Darlington arrays ULN2003 & ULN2803.Edited by larny 2019-05-02

I looked at the site that Trevorc gave me but it appears I would need to build a PCB to do it.
I tried to enter the 16F1708 into WINPIC following the procedure given in the help, but I eventually reached an impasse. I could not work out how to proceed further. The instructions are vague, so unless someone can help me, I will give up that option.
I'll select a different PIC - one that is in WINPIC.
Any assistance will be appreciated.

Before I give up on the 16F1708, I have decided to see if anyone can help me with WINPIC. The situation is as follows:-
I gave up trying to programme a 16F1708 with PICKIT3 as it (i.e. PK3) appears to be faulty (I tried several suggestions from people on various forums but nothing worked.
Several said that the PK3 "is a pain".
I have always used WINPIC to programme PICs, but the 16F1708 is not included.

I tried to enter the 16F1708 into WINPIC according to the WINPIC help document "Help - my PIC is not supported".
I managed to do part of it, but eventually came to an impasse. I could not work out what to do next. The instructions are not clear.

Does anyone know how to do it?
I have attached a screen grab of the WINPIC screen which shows how far I got.
The second screen grab shows the same screen for a 12F675.

Any assistance will be appreciated.
