dumb question

[mackrackit]

Sorry but didnt get this:And you were to work on a button part of the code to change the way the LEDs blink.
To work where?Do I have to change something?

Now you have to write your own code so when you push the button on the demo board a different set of LEDs blink. The manual will be a help while doing this.

The code you have posted has two oscillator settings, you only want one.

Witch manual?And isnt the way I did it before right?

[osceola]

I create this code,after the model you send me,but just to understand,I would like to know where do I have to make changes -because now is blinking one LED and then 3 LED at time:

And here the LEDs blink in other way:

[mackrackit]

What does this do?

PORTC = %11100000

The manual you can not find is linked on the page where you got your demo.

This page has samples that you need to work through and understand

Thank you!

[osceola]

I have compiled this and dont know why only 3 LEDs are blinking and the 4th doesnt blink.Could you tell me where I am mistaken,to understand better.Thank you
