1. First, the problem is my PIC no response at all.
2. output msg is BUILD SUCCEEDED.
3. this program is only to control LEDs blinking
4. I'm using MPLAP IDE, MPASM Assembler v5.44
5. I used MPLAB SIM to simulated this program
6. The OSCCON i want to set it as 01100010(62H),
but dunno y simulation result is always show that OSCCON is 01100000(60H)
7. This Fcuk-ing shit still doesn't WORK
8. Last, if u guys need any photo or anything else to better understand with my problem, pls feel free to ask, thanks =]

Have you checked whether you have turned off the ADC and the Comparators/PWM first?

[FakeSheep]

as im using pic18f4550
I not really sure how to do it
if to off the Capture/compare/PWM and ADC module
is it should be like this?
movlw H'00'
movwf CCP1CON
movwf ADCON0

i already tried but still can't work..have u try my program? is it working with ur chip?

org 00020h
Start:
movlb B'00000010' ;FE0H, select Bank 2
movlw B'01100010' ;FE8H,62H Use internal OSC at 4 MHz
movwf OSCCON
movlw B'00000000'
movwf TRISD ;F93H set all Port D to output
clrf PORTD ;PORTB,F81H
;Your instruction says PORTD but your comment says Port B, where did you connect your LED?
movlw H'00'
movwf LATD

I simulated in Proteus and it worked.
May be you should add a little more looping in your delay subroutine to make the flashing more visible. Running at 4MHz, my rough calculation got that you delay is only 132 mS which is too fast for your eyes. Try this:-

CODE: SELECT_ALL_CODE

;PIC Time Delay = 1.0000020 s with Osc = 4.000000 MHz

counterA  equ 0x02
counterB  equ 0x03
counterC  equ 0x04

   movlw   D'6'
   movwf   CounterC
   movlw   D'24'
   movwf   CounterB
   movlw   D'168'
   movwf   CounterA
loop   decfsz   CounterA,1
   goto   loop
   decfsz   CounterB,1
   goto   loop
   decfsz   CounterC,1
   goto   loop
   return

Yes, i already checked my hardware
But 1 thing is, i tried to set my OSCCON as B'01100010' which is internal OSC with 4Mhz
i simulated it and the result show below:

i cant able to set OSCCON as B'01100010', but only B'01100000'

bit 1-0 SCS1:SCS0: System Clock Select bits
1x = Internal oscillator
01 = Timer1 oscillator
00 = Primary oscillator

The primary oscillators include the External Crystal
and Resonator modes, the External Clock modes and
the internal oscillator block. The particular mode is
defined by the FOSC3:FOSC0 Configuration bits. The
details of these modes are covered earlier in this
chapter.

I am not familiar with the MPLAB simulator. But if it set the 1x internal oscillator to 00 Primary Oscillator. The control is passed to Configuration bits CONFIG1H......

i still can't work with it...any sample can let me refer?
or suggest me any other assembler or IDE etc?(ASM based pls, I'm suck in C, yet)
bcoz seems like no much body are using MPLAB...
it is quite sad that no much body can help with my problem and i can't even control a LED blinking
i stuck at situation like now for a long time

[ABSF]

What about this program?

CODE: SELECT_ALL_CODE

;connect LED to PortD, Bit 1
#include P18F4550.INC
CONFIG WDT=OFF; disable watchdog timer
CONFIG MCLRE = ON; MCLEAR Pin on
CONFIG DEBUG = ON; Enable Debug Mode
CONFIG LVP = OFF; Low-Voltage programming disabled (necessary for debugging)
CONFIG FOSC = INTOSCIO_EC;Internal oscillator, port function on RA6
