Hi all,
I tried to program PIC18F1320 with 3 volt(LVP).My programmer is PICKIT 3 which i bought it from Farnell.
I activated the LVP bit on config and connected the PGM pin to PICKIT 3. When i program it with 5 volt, there is no problem, it programs with success, but i want to program it with 3 volt, it allerts " Programming failed at Program Memory address 0x000000".

Is there anybody faced this problem? Or is there any specific thing i have to do about programming pics with low voltage?

Thanks..

do a Google search, there are three resistors that need to be done with wires in the pickit 3

I found that pdf http://ww1.microchip.com/downloads/e...ow_Voltage.pdf

But all these resistors are also "0" ohms in my programmer.

I am getting an error when I use Pickit3. The error is:

"Unhandled exception has occurred in your application. If you click continue, the application will ignore this error and to continue. If you click Quit, the application will close immediately. Data parameter cannot be longer than 136bytes. Parameter name: Data"

I have the latest Mplab which I reinstall but in vain. If Pickit 3 is not attached on the USB the Pick program come on. If the pickit3 is attached to the USB and start the Pick3 program I get "Pick 3 has stopped working, Windows is checking for solution to the problem"
If I unplug the pickit3 and open the Pickit 3 program then plug the pickt3 unit to the USB then click Tools, Check communication I get the error above. I can see there are a lot of activities on the LED of he Pickit3. The status and active LED flash until the error.
Operating system: Windows 7 64bit, Mplab 8.9
I am pulling my hair and really don't know what else to do. Pleas any leads to resolve the problem. Many thanks in advance.

Regards,

Yves

I haven't used the pickit3 but recently my pickit2 program indicated my p2 needed the firmware downloaded again.
so in the Tools menu there is a choice to download pickit2 operating system... that fixed it for me

you might also check over in the microchip forums at microchip.com

good luck
