I just purchased the PICKit 3 ... I already had MPLAB IDE installed and the Lesson PDF asks me to install MPLAB C Compiler for the PIC18 v3.13 - so I donwloaded and installed the latest ... mplablc18 v3.43 (lite version).

Part of lesson 1 navigates to C:\MCC18\lkr to include some linker files - but I don't have that directory. I am supposed to include the following files ...

• 18f45k20.lkr
• 18f45k20_e.lkr
• 18f45k20i.lkr
• 18f45k20i_e.lkr

I did a global search in my system and I found two places that have

18f45k20_g.lkr

Here: C:\Program Files (x86)\Microchip\MPASM Suite\LKR
and here: C:\Program Files (x86)\Microchip\mplabc18\v3.43\bin\LKR

Did I install the wrong program? How do I find the files the lesson wants to use?

Thanks,

Use the lkr file "C:\Program Files (x86)\Microchip\mplabc18\v3.43\bin\LKR" and you should be fine

 

Thanks.

I also learned that, since C18 v3.40, no linker files are required

Just a recap:

Running Windows 7, the MPLAB 8.* software can't seem to get past this stage of trying to recognize the PICKit 3:

At this point, the PC IDE just freezes. It flashes that it is connecting in the bottom left corner of the IDE. A progress bar keeps filling up and starting over. 10 minutes of nothing. So I shut it down and reset the PICKKit3 (holding down its button while giving it power.

After a bit of deliberation, I download MPLAB X and try it. No luck. This time, the whole app just shuts down after the "RS download complete" line.

I wondered if it was my PC ... so I installed MPLAB X and the compiler on my MAC ...

Ok - so after getting this message (I've got two PICKit 3 Debug Express kits) I plug in the other Debug Express target card. No luck. Same error. Since I'm farther along now, I decide to pop the PICKit 3 back into the PC and see what happens.

And great, the IDE works much better (doesn't attempt to download or install firmware) but it reaches the exact same final error: Target Device was not found.

I finally thought about "power" ... and turned that on in MPLAB ...

and it worked. I can see the moving LEDs on the card!
