I bought myself recently a kit from Microchip ( DV164131). The kit consists of a PICKit3 programmer and a evaluation board with PIC18F45K20 microcontroller.
I download MPLAB X IDE v. 3.65. But when I wanted to program a microcontroller, I got a failed message:
The status LED on the programmer turned red. I downloaded the program “PICKit 3 Programmer Aplication” from here. As standard I installed as any other program on my computer. Once installed, I launched it and chose it: Tools -> Revert to MPLAB Mode (when the programmer was connected to a PC).
After that I tried to upload the compiled soft to the microcontroller on MPLAB, but I got this message:
I chose: File -> Project Properties -> PICKit3 -> Option categories -> Power and match box “Power target circuit from PICKit3”, because my eval board didn’t have external supply. After this, after trying to upload the software I saw a message:
And my eval board came to life.
I had a similar problem. Thanks for the hint of the solution.
Frequent beginner mistake. It is also important to correctly select the voltage supplying the board.
Hello Nice tuto .. i have the same trouble now it’s all right good job
Thank you all, all these ideas were a good background to update. But for me it didn’t work and went further, after activating 5volts i even used a multimeter and got 1.08 volt on vdd of pickit3. So didn’t work with mola x.
Solved the problem by using pickit software. I could program the pic16f84a.
i tried the menus which you said above but still i got the same connection failed.
i connected the pickit3 programmer with my laptop
The target circuit may require more power than the debug tool can provide. An external power supply might be necessary.
Connection Failed.
any other solution kindly support
