8051 program – serializing data

Serializing data is a way of sending a byte of data one bit at a time through a single pin of microcontroller. There are two ways to transfer a byte of data serially:

• using serial port
• Transferring data one bit at a time through a single pin

Serializing data is one of the most widely used applications of the rotate instruction. Using that concept and the rotate instruction, we transfer a byte of data serially (one bit at a time).

; Serializing data
	ORG 0H
	MOV A, #0C5H
	MOV R7, #8
LOOP:	RRC A	; move bit to carry
	MOV P0.1, C	; send bit on data pin
	DJNZ R7, LOOP
	END
