PIC 16F877A

[San4N]

hI,

 

I am new to this forum. i need help of someone to guid me to program the PIC16f877a.

I am using PIC to control the relays. for Pneumatic Cylinders and DC Motor.

For time being. if some one can help me.

want to use push button to control two relays with timer.

when push button is on> o/p 1 on for 3 sec then o/p 2 on for 10sec . the sequence continues.

 

 

#include<16f877a.h>

#use delay(clock=20000000)

#fuses hs,noprotect,nowdt,nolvp

 

#byte PORTD=8

#byte PORTB=6

void main ()

{

set_tris_d(0b00000000);

set_tris_b(0b00000011);

set_tris_e(0b00000000);

portd=0b0000000;

do

{

   if(input(PIN_B0)==0)

{OUTPUT_HIGH(PIN_D0)&&Output_LOW(PIN_D1);}

delay_ms(300);

  //if(input(pin_B0==0)

           {output_HIGH(pin_D1)&&OUTPUT_HIGH(PIN_D0);}

delay_ms(1000);

 

}

 

while (1);

 

 

this is my code. i am using ccs compiler.

 

thank you, , ,

i thnk if u use timer using interrupt it will be useful.

can u plz share your circuit diagram & code on my mail id [email protected].

& function delay_ms(300); will give you delay of 300 miliseconds not 3 seconds
