This thread is to help us simple folk with a list of PICs, oscillator speed and configs until you know what files to use and how to read the datasheet.
This is what I'm using in my current project:
PIC 18F4550, 20 MHz external oscillator, USB operation, not using power from USB cord, using Lab-X1
PBP 2.60C
MPASM v4.02
This goes at the top of my PBP program. You can group them all in ASM/ENDASM if you prefer that method:
@ __CONFIG _CONFIG1H, _FOSC_HSPLL_HS_1H
@ __CONFIG _CONFIG2L, _PWRT_OFF_2L & _BOR_ON_2L & _BORV_43_2L & _VREGEN_ON_2L
@ __CONFIG _CONFIG2H, _WDT_OFF_2H
@ __CONFIG _CONFIG3H, _CCP2MX_ON_3H & _PBADEN_OFF_3H & _LPT1OSC_OFF_3H & _MCLRE_ON_3H
@ __CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _ICPRT_OFF_4L & _XINST_OFF_4L
DEFINE OSC 48
Comment out the default configs in 18F4550.INC in PBP folder with a semi-colon like this:

One thing people don't realize is that comments don't take up any space on a PIC (unless you ENABLE Insert Source File Comments in MicroCode Studio under VIEW / COMPILE AND PROGRAM). Feel free to put as many comments at the top (or bottom) of your program if it helps you remember what config does what.
I like to list them all so I don't have to go back to the datasheet/file when I want to change something.

Note: My first version of PBP came on a diskette and I still consider myself a beginner.
Re: Voltage regulation circuit 12V to 5V in 5A range
I only used the bottom regulator on that schematic.
Demon Yesterday, 19:30I have 9v 2a wall adapter coming in today, and a 7v 2a coming in tomorrow.
That should reduce wasted heat a lot.
