Ye, I though about it,
But I use the button as "Rising Edge" so when the button is pressed there is no interrupt yet.

I didn't say anything about the button causing the interrupt did I?Originally Posted by menta
If you re-read my post, you'll see that I said that a timer causes an interrupt and the button input is read during that interrupt. Therefore, it doesn't matter if your button pulls a line high or low, or what, as long as you are able to read the state of that pin during the interrupt.

Right,
Thanks.

Just a question Menta, why did you set the ports as analogue if you are using them for a switch???
|
They aren't...
PortA is set for analog...
PortB is set for digital (ANSELH = 0). The comment behind the line in the code a few posts back is technically correct, but slightly misleading.

Thats right.
