[SOLVED] Problem programming a 16F1708 using PICKIT 3

[ljcox]

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.

Have you got the PicKit3 options (in the MPLAB) set to LVP as that would explain the low voltage.
(I've not used MPLAB for a very long time so I can't tell how to check for this setting in the IDE.)

Thanks Susan. No it is not set to LVP. Someone on another forum gave me a procedure to refresh the firmware in the PK3. I did that & now I get the correct Vpp voltage but the waveshape on the scope does not look right as you will see in the attachments. So it still won't programme a PIC.

Use MPLAB IPE

which is specially design for PICkit3 . Once you installed MPLABX 3.25 then MPLAB IPE on your desktop

MPLABX/MPLABX IPE versions 5.15 are the latest. Version 3.25 is quite old.
