Pickit 3 - Target Device Issue

**MikelMD** · 04-30-2017, 12:12 PM

Ok - so I now have created my own Pickit 3 to PIC16F688 connection, I have set all of the correct setting (PIC selection/Family/voltage which is 4.87)) and I can read the PIC. When I select and load the hex and click program, I get the error:
The following areas will be programmed:
Program memory start address = 0x0, end address = 0xf3
Configure memory
Address 1 expected Value: 2846 Received: 0
Failed to program device
2017-04-30 12:04:53 - Programming Failed
Pass Count: 0

Attached is the HEX file.

Thanks all - I feel I am one step away!

Try a slightly lower voltage. As I said, I had to go down to 4.5v before mine would program.

You also said you managed to "heat" the chip IIRC. You may want to try a new one.

I tried a diff PIC and dropped the V to 4.5. Same error.

In addition, I can read the PIC, Verify and erase the PIC. could the hex be incorrect?

If you can read the PIC then the connections are good. I would suspect the hex file.

D/l another and same results. I have the SAM file and I created a HEx and I d/l a hex from the site and still same error.

In the MPLAB IPE app, aside from voltage 4.5 and the family and device settings. Are there any other settings that I must change from the default?

Funny thing: I perform an erase and it states erase device complete, the I to a blank check and it states device is NOT blank!

Are you still using AUTO Import Hex & Write....For me, I do a File/Import Hex.....
If I get a full import then I can generally write it.

When I program I use the IPE- there is a setting to slow down the programming and (this one is likely a red herring) another to choose what gets programmed -memory eeprom etc.
Have you tried to slow down the processes if possible? A reasonably short USB cable?

So, I have slowed down the programming, along w/ all other items. I thought I would share this. I performed a blank check on this PIC (which claimed it was not blank) then I exported the data. Below is a snippet of what was in the file.
:020000040000FA
:1000000000000000000000000000000000000000F0
:1000100000000000000000000000000000000000E0
:1000200000000000000000000000000000000000D0
(continued until)
:1043E00000000000000000000000000000000000CD
:1043F00000000000000000000000000000000000BD
:084000000000000000000000B8
:00000001FF

I then went to File, Import and selected the HEX file, this is what the log provided:
