According to the code piece given in the lower part on the PIC microcontroller in the circuit, when the switch positions given in Table 1 are applied, what is the direction and angle of the step motor rotor (according to the given reference position (R))? (show by calculating). Results given without calculation will not be evaluated. The 5V stepper motor used in the circuit has a step angle of 1.5 . Each key combination given in Table 1 is not applied until the stepper motor reaches its final position (stops). The motor (Bank 1) will start from the R point. #include #fuses XT,NOWDT,NOPROTECT,NOBROWNOUT #use delay(clock=4000000) #use fast_io(a) #use fast_io(b) int i,j,x=5,y=0; int seri[]={10,9,11,8,7,12,14,4,13,6,5,2,15,3,0,1}; #int_rb void kesme_1() { if(input(pin_b4)) x = x + 2; if(input(pin_b5)) x = x * 2; if(input(pin_b6)) x = x - 4; if(input(pin_b7)) x = x * 3; if(input(pin_a0)) x = x * 2; if(input(pin_a1)) y = 1; for(i=0;i=0;j-2) { output_b(seri[j]); delay_ms(50); } } x = 10; y = 0; } void main () { set_tris_a(0x0F); set_tris_b(0xF0); output_b(0x00); enable_interrupts(int_rb); enable_interrupts(GLOBAL); while(1); }
