PIC 18 IO Lighting LEDs In a Row!

Nice Special Effect — Debut pic — Episode#04

Hi, this code makes the LED’s lighting in a nice sequence o/

All we need is a single button! ❤ git

Here is the code:

Tips n Tricks

Just create a method (increment), a counter variable and a switch like this:

unsigned char myCounter = 0;
void increment (unsigned char counter)
  {
     switch (counter)
       {
           case 1:{PORTD.RD0 = 1; break;}
           case 2:{PORTD.RD1 = 1; break;}
           case 3:{PORTD.RD2 = 1; break;}
           case 4:{PORTD.RD3 = 1; break;}
           case 5:{PORTD.RD4 = 1; break;}
           case 6:{PORTD.RD5 = 1; break;}
           case 7:{PORTD.RD6 = 1; break;}
           case 8:{PORTD.RD7 = 1; break;}
           default: {PORTD = 0; MyCounter = 0; break;}
       }
  }

Yeah! Easy, right?

Now, modifying the same previous code call the method increment instead of LAT:

//PORTD.RD0 = ~ LATD.RD0;
increment(++myCounter);

And that’s all!

In the next lesson let’s make a CHASING LEDS :)

And that’s it

Thanks a lot! See you in the next episode.

Bye!
