I had a look in my 8051 reference and did fine what I needed to do. Mov R5,#8
HERE: Mov C,P3.0 ;bring in bit on P3.0
RRC A ;rotate right through carry
nop
nop
DJNZ R5, HERE
Mov R3,A ; put byte in R3This will simply whizz round the loop at whatever speed your 8051 happens to be running. You have absolutely no guarantee whatsoever that this will be sampling P3.0 at any sensible position within successive bits of your data stream! But, if it keeps you happy... |
