Pickit 3 - Target Device Issue

**MikelMD** · 04-25-2017, 07:43 PM

Hi All,

I picked up a PicKit 3 clone and I am using the MPLAB IDE 8.92. I have read many boards, FAQs and I feel that I am close, however, no cigar! I keep running into the Target Device ID (0x0) does not match excepted Device ID (0x420).
The MPLAB is power is checked and set to 5v.
On the board, I have followed the instructions for DIP 8,14,18,20: J1 on 2, all open and J7 on 2-3.

For fun, I have tried to move the PIC around and all I get is a hot PIC and a Overcurrent logic has detected a fault condition....

Thanks in advance for any assisatnce.

looking at this as best as I can looks like you might have the pins not set for the chip you have

what device are you using?

**davros** · 04-25-2017, 08:34 PM

Do you have it set to power the target?

I am trying to program my U6-U8 – PIC16F688 Microcontrollers. The Pickit 3 is a clone. I am using the MPLAB IDE v8.92 and I in the settings for Power, I have the power target circuit from pickit 3 checked at 5v.

While it is not the cause of your current problem, I suggest you set the voltage to 4.5v. At 5v the programming was unreliable. At 4.5v I did not have any failures. I will look at the spec sheet to give you alignment when I get home from work

Hi, I'm not a PIC guy but I have been watching some tutorials on them with a view to learning. This was on that delt with Pickit 3 issues, it may help, if not it's only 15 mins of your life wasted.

Thanks for the movie. I watched it and using the pickit 3 programmer I was able to d/l the OS and get the device ID on the clone pickit 3. However, when I attached the pickit adapter and chip, the app does not detect the chip. So, I am feel that the settings are incorrect. On the board, I selected "DIP 8,14,18,20:" and the jumpers are as follows: J1 on 2, all open and J7 on 2-3. I placed the chip top left is one facing the pull down locking lever. The reply I get on the application: No device detected.

Looks to me that you need to move your chip 1 slots closer to the 3M. You should have 3 slots open on the non 3M side.

Far away from the 3M is the DIP20 - no open slots
then up one slot is the 18 pin - one open slot
up one slot is the 16 pin - two open slots
now your 14 pin. - 3 open slots

hmm. To me it looked like three empty pins on the non-3m end and then the chip starting in the fourth pin on the non-3m end. The notch on the chip should be on the 3m end of the socket.

After that you need to set the jumpers for a 14 pin chip. Then you need a total of 7 jumpers.

J1 position 2
J2 and J3 and J4 and J5 and J6 and J7 all need jumpers between positions 2&3
