dear all,
It is continue my learn about C language for mcs51.
Now I use SDCC (KEIL demo too big for download) for learning.
I have simple program in assembler below :

;*********************************************************
init:
setb c
mov a,#0
setb p3.7
right:
rrc a
mov p1,a
lcall delay
jnb p3.7,left
ljmp right
left:
rlc a
mov p1,a
lcall delay
jb p3.7,right
ljmp left

delay:
mov r0,#10
loop1:
mov r1,#255
loop2:
mov r2,#255
djnz r2,$
djnz r1,loop2
djnz r0,loop1
ret
end
;**********************************************************
Does anyone can convert my program above with SDCC language?
thank you verymuch

regard
hen.
