Trouble reading a button

[hadium]

Hi! I have been using C18, and have just changed to CCS. I'm simply trying to toggle an LED using a button input. I can flash an LED through code, but not through the button.

Please see my code below:
[ while (1) {

while(input(PIN_A0)) {
output_high(PIN_D1);
delay_ms(500);
output_low(PIND1);
}

while(!input(PIN_A0)){
output_high(PIN_D2);
delay_ms(500);
output_low(PIN_D2);
}
}
]

Any help understanding why this might not work would be greatly appreciated!

Thanks!

Sorry, there was an error in my code. Here is the revised version:
while (1) {

while(input(PIN_A0)) {
output_high(PIN_D1);
delay_ms(500);
output_low(PIN_D1);
}

while(!input(PIN_A0)){
output_high(PIN_D2);
delay_ms(500);
output_low(PIN_D2);
}
}

If you want the LEDs to flash, you've got to have a delay for both
the high and the low time. Add the lines shown in bold below.

Thanks for your reply. I tried what you suggested, but no luck. I can't make the LEDs trun on at all!!!

Post a test program. Show the code that you've already posted,
but also show the main() function, and all #include, #use, and #fuses
statements.

When post the code, highlight all of it and then press the "Code" button.
This will make it be formatted better.

Also, when you post, make that HTML is disabled. Look below the
window where you type in your post. There is a checkbox labeled:

Thanks so much for your help. Here is my program. I used the project wizard to set it up.

Can you post the #include, #use, and #fuses statements ?
They are likely to be in this file:

Here's the .h file:

Try NOLVP in your fuses. This one bit me when I first started using CCS.
