PIC 18 IO Chasing LEDs

The net result is that LEDs seem to be chasing each other — Debut pic — Episode#05

Hi, in this new quite nice PIC project we’re gonna light LEDs like so: ❤ git

Fig 1. Chasing LEDs

Here is the code:D

There is no science here. In the loop, just Send j to PORTB, wait .1 s, bitwise left j and assign to j itself; IF last bit then reset j. That’s all!

for(;;)                              // Endless loop
    {  
        PORTB = j;                   // Send j to PORTB
        Delay_ms(100);               // Delay 1 s
        j = j << 1;                  // Shift left j
        if(j == 0) j = 1;            // If last LED, move to first one
}

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

And that’s it!

Thanks a lot! See you in the next episode.

Bye!
