Simple 3 Button On-off With 12f629 (mikroC)

a simple 3 buttons on-off with pic12f629.

it's written with MikroC

start the code with ''int''
----------------------------------------------------------

int x0,x1,y0,y1,z0,z1; ////// with this the GPIO outputs could stay on or off

void main() {

GPIO = 0x00; ////// all outputs are 0

CMCON = 0x07; ////// Disable CMCON PORT

TRISIO = 0b00111000; ////// inputs-outputs setup, 0=output 1=input (3 outputs/3 inputs)

x0=1;x1=0; ////// when the PIC starts x0=1,x1=0

y0=1;y1=0; ////// when the PIC starts y0=1,y1=0

z0=1;z1=0; ////// when the PIC starts z0=1,z1=0

----------------------------------------------------------

----------------------------------------------------------
while (1)

{

if ((GPIO.GP5==0)&&(x0==1)) ////// if the GPIO.GP5 grounded (pressed button) and the same time x0=1 (from the

begining of program, you see this at the previous step)

This will happen

{

x0=0; ////// the x0=1 it will be 0

x1=1; ////// the x1=0 it will be 1

GPIO.GP0=1; ////// turn the led on ( the - of the led is connected to the Ground and the + at GP0, pin 7 ) . delay_ms(600);

}

if ((GPIO.GP5==0)&&(x1==1)) ////// if the GPIO.GP5 grounded again and x1=1(from previous pressed button)

This will happen

{

x1=0; ////// x1=1 go back to 0

x0=1; ////// x0=0 go back to 1

GPIO.GP0=0; ////// now the led is off and the program wait for ((GPIO.GP5==0)&&(x0==1)) to turn on again .

delay_ms(600);

}

This is for the one button and led. You have two more. See the .txt file.

you can use this at many projects as Latching Relay..

turn on and off circuits or devices with relay or not.
