I want to program PIC18F such that with push button 1 pressed, the relay/LED is on for 1 sec, off for 2 sec continuously unless button 2 pressed , in which relay/LED will be on for 2.5 sec and off for 5 sec. How to achieve this? I tried giving delay (as given below) but when i press RD1 it does not recognize. I want PIC to change timing whenever i press other button.
while(1) { if(PORTD.RD0==0) { PORTB.RB0=1; delay_ms(2500); PORTB.RB1=0; delay_ms(5000); if(PORTD.RD1==0) { //condition of while RD0 becomes false //start a different delay } } }You can program like this :
............. ............. TRISD.F0 = 1; TRISD.F1 = 1; ............. ............. while(1) { while(PORTD.F0 == 0) { LATB.F0 = 1; // Use LAT register to write output in 18F Delay_ms(1000); LATB.F0 = 0; Delay_ms(2000); } while(PORTD.F1 == 0) { LATB.F0 = 1; Delay_ms(2500); LATB.F0 = 0; Delay_ms(5000); } }
