#107301 - example 500hz and 10 khz square wave Responding to: ???'s previous message |
i send two examples...
but i dont relate various frequency and this program... TO GENERATE SQUARE WAVE OF 500 Hz USING TIMER 1 MODE 1 mov tmod,#10h ;timer 1, mode 1 start: mov th1,#0fch ;load the count to t1 mov tl1,#68h cpl p1.0 ;compliment output setb tr1 ;start timer back: jnb tf1,back ;check timer 1 overflow flag clr tf1 sjmp start TO GENERATE SQUARE WAVE OF 10K Hz USING TIMER 1 MODE 2 mov tmod,#20h ;timer 1,mode 2 mov th1,#210 ;load the count setb tr1 ;start timer back: jnb tf1,back ;check timer 1 overflow flag cpl p1.0 ;compliment output clr tf1 sjmp back |
