Change according to your needs.

Code:

#CONFIG CONFIG OSC = XT ; XT oscillator CONFIG OSCS = OFF ; Oscillator system clock switch option is disabled (main oscillator is source) CONFIG PWRT = OFF ; PWRT disabled CONFIG BOR = ON ; Brown-out Reset enabled CONFIG BORV = 20 ; VBOR set to 2.0V CONFIG WDT = ON ; WDT enabled CONFIG WDTPS = 128 ; 1:128 CONFIG CCP2MUX = ON ; CCP2 input/output is multiplexed with RC1 CONFIG STVR = ON ; Stack Full/Underflow will cause RESET CONFIG LVP = OFF ; Low Voltage ICSP disabled CONFIG DEBUG = OFF ; Background Debugger disabled.

Hi, Ioannis

The main question is ...

" How much would you pay for it ??? " ...

BTW ... How much would consumers pay for internal/external drivers to include into PBP Package ???

Good questions, ehhhhh ... :rolleyes:

Well, currently there are two options, both free:

1. MCC the Microchip Configurator. Can be used as standalone, no need to use thw MLABX IDE

2. The Great Cow Basic that can automatically make the configuration without user intervention. After compiling, you can open the asm file and copy the configuration.
