How to make toggle switch using mikroc?

asking · Jan 25, 2013

Hello,
I tried to use default mikroc library to a toggle my one variable with 1 or 0. Means led = 0 led = 1 means I need to keep 1push button once clicked it will be either 0 or 1. Please provide me simple code how to do it.....

try it ..using push button switch when ever your switch=1 port A0=1, at the same time Port B7=1,else 0.

can i use Do function again ? because i already have 1 do function afte void main in my program....but mikroc wont allow more than do function....if i remove do and compile it works fine but if i keep do function and then try to compile then it gives me error. so m little bit confused that its my programming error or its limitation of mikroc to use the Do function...only 1 time...or should i add the new code within that do function...?

post your full code.

Simple Code is

Code:

 [syntax=c]
void main() {
         TRISA.F0 = 0x01;
         PORTA = 0x00;
         TRISB.F0 = 0x00;
         PORTB = 0x00;

         while(1) {

                 if(PORTA.F0 == 1) PORTB.F0 = ~PORTB.F0;
         }
} [/syntax]

} [/syntax]

ok great...what if i want to replace PORTB.F0 with some variable unsigned short LED. it will be

Code:

if(PORTA.F0 == 1) LED = ~LED;

?

Means when i click on switch, Variable LED = 1, and if i click switch again it will be LED = 0; ? because i dont want to use push to on and push to off switch i just want to use push to on switch to toggle the output 0 or 1....

                    if(hour>=24)
                    hour=0;
                    hour = Binary2BCD(hour);

                    write_ds1307(2, hour); //write hour
                    break;
            case 2:
                     minute = BCD2Binary(minute);
                     minute = minute + set;
                     if(minute >= 60)
                        minute = 0;
                     if(minute < 0)
                        minute = 59;

                     break;
          }
        }
     }

i just want this condition to be true...by pressing button, and it should be false if i press button again. Means just toggle the condition true or false.

if(d1==0)d1+=12;
else if(d1>=13)d1-=12;

i tried but no change so i need for this. My other switch works fine as shown above in my code.

Code:

if(PORTC.F7 == 0)
      {
            Delay_ms(30);
            if(PORTC.F7 == 0) {
                LED = ~LED;
           }
         }

This worked like charmed....thanks here my LED is flag which is turned 0 and 1. It was not turning because i kept it LED = 0; it should be LED == 0;

jayanth.devarayanadurga · Jan 26, 2013

LED == 0 is not right. PORTC.F7 == 0 is right. LED is connected to output pin, so, LED = 0 makes sense.

Jayanth,

i already told, LED is variable (FLAG) i just need to turn it 1 or 0 for proving my condition true or false. Its not connected to output pin dear....its just Variable in program.

Guys, I want if i pressed the button in RA0 to make the led on PortB.F7 to light up till next press . so even if i released the button the led should be on till next press any hep on this please .

Hi jayanth,
I did the same but the Led will be On for 100 ms only and will be OFF again , i think you did not get my point and i will be more clear . when i power the Circuit the LED should be Off then if i pressed the Push button the LED should be ON and keeps ON even if i released the button and when i pressed the button again it should return OFF and be OFF till next press .

Try this code. It is for PIC16F887

Code:

 [syntax=c]
#define SW PORTA.F0
#define LED PORTB.F7

void main() {
         TRISA.F0 = 0x01;
         PORTA = 0x00;
         TRISB.F7 = 0x00;
         PORTB = 0x00;
         ANSEL = 0x00;
         ANSELH = 0x00;
         CM1CON0.C1ON = 0;
         CM2CON0.C2ON = 0;
         
         while(1) {

            if(SW == 1) {
                 Delay_ms(150);
                 if(SW == 1) {
                      LED = ~LED;
                 }
