#175102 - Ask yourself this
Responding to: ???'s previous message
DELAY_20MS: MOV R0,#4607     ;4607 cycles for 20 ms             
_ABCD:  NOP
        NOP
        DJNZ R0, _ABCD
        RET

 


Hmm. Ask yourself this: what is the largest number you can put in R0 ?

Satisfy yourself that this works, and then rewrite it properly, and use the timers, as this was discussed in great detail very recently.
