| MPLABX and CCS led blink not as I want |

I made this program...
http://pastebin.com/WSYK0DsU
what it should do:
-blink all leds from LED1 to LED6 (startup signal)
-set LED1 to 1, wait 50 ms (default value for variable K, blink frequency), set LED1 to 0; and repeat this.
-when I press BUTT1 (stays for BUTTon, non [spam]), the variable i become 1; when I press BUTT2, the variable j become 1.
-when i is 1, k=k+10; and when j is 1, k=k-50, so with those buttons I can adjust the frequency.
What it actually do:
-blink main leds (1-6) (startup sequence)
-blink LED7 forever.
why?????? |

How is it supposed to get from your first "while(1)" block of code to the second "while(1)" block of code that flashes LED1?

If i put all the code in one while(1) the problem is the same.

So when are you going to fix the problem pointed out to you
by gpsmikey and show the new code that doesn't work? No one here is a
mind reader...

By making one while with the code from the variables of the buttons to the end.
Delete lines from 64 to 68. |

| Are your switches active high or active low? |

Ah yes, missed those two - I've been trying to train myself to write code so the compiler will catch those. The answer is fairly simple - instead of "if ( k = 0 )" which sets K to 0 and is always true, you write it as "if (0 = k)" and the compiler will throw it out at which point, you go "duh" and change it to "if (0 == k)" and all is well. Takes a bit of retraining for these old grey cells though
