Programming PIC

[moraes]

Hello

I've just finished soldering everything on my megadrum, but i'm having some trouble to do the programming. I built it with PIC18F2450, instead of 18F2550. When i use WinPic to program it, it says the "Programming Fail". I used the firmware which i can find on the forum. Also, the crystals I have are for 12MHz and 16MHz. The version I built is 32 inputs.

This was the programming error:
"Info: Loading definitions for "PIC18F2450" from C:\Arquivos de programas\WinPic\devices.ini .

Can somebody help me out please? thanks

I've found the firmware for 2450, but now it shows this error:

I hope this will help: http://www.google.co.uk/#sclient=psy&hl ... &oq=&pbx=1
I should note that I myself have not managed to program PIC18F2450 using the ICSP programming cable and WinPic otherwise I would be suggesting using it instead of PIC18F2550 since it is cheaper.
