    Square Waveform

    The document describes an experiment using an 8051 microcontroller to generate a 1 kHz square wave by interfacing with a digital-to-analog converter. The program uses a delay loop and moves alternating values of 0 and 255 to the DAC port address FFC8 to output the switching voltage levels for a square wave. The result is that a square waveform can successfully be produced using an 8051 and DAC interface in this way.

    INTERFACING DIGITAL TO ANALOG CONVERTER FOR GENARATING SQUARE WAVEFORM

    Aim:

    To perform 8051 based DAC Interface experiment for generating 1 KHZ Square waveform.

    Program:

    OPCODE LABEL INSTRUCTION

    START MOV DPTR #FFC8

    MOV A, #00

    MOV @DPTR, A

    LCALL DELAY

    MOV A, #FF

    MOVX @DPTR, A

    LCALL DELAY

    LJMP START

    DELAY MOV R1, #05

    LOOP MOV R2, #FF

    HERE DJNZ R2, HERE

    DJNZ R1, LOOP

    RET

    Result:

    Thus we can generate square waveform using 8051 based DAC interface.
