PostPosted: Mon Oct 11, 2004 1:01 pm     Reply with quote
Have Pbuttons attached to PIN_B4 and PIN_B5. Want to change
a value up&down according to wich Pbutton is pressed.

any suggestions?

#int_rb
rb_isr()
{
char x;
x = input_b();

if((x&8)==8) //somethings wrong here...
{
//value +=1; B4
}

if((x&16)==16) //and here..
{
//value -=1; B5
}
}
