heres what im trying to test just asimple PWM signal, i cut it out of my main code for testing. This is the first time ive programmed a chip and made my own circuit for it. But im not sure what im doing wrong, it simulates fine.

org 0
;
ljmp 080h

org 80h

mov sp,#050h ; Set stack pointer to address 50h

jmp DELAY
org 100h

DELAY:
mov a,#000h
mov p1,a
mov r3,#0e5h
LP:
djnz r3,LP ;DELAY .5 ms with a 11.0592 crystal
mov r3,#0e5h
LP2:
djnz r3,LP2 ;DELAY .5 ms **total 1ms**
mov r3,#044h
LP3:
djnz r3,LP3 ;DELAY .5 ms **total 1ms**
mov a,#0FFh
mov p1,a
mov r3,#0e5h
mov r4,#02ah

LP4:
djnz r3,LP4
