Timer Question

[yoyodyne]

For practical purposes, yes,

if(disabled_mode) // not disable_mode - my bad

is really the same as if(disabled_mode != 0)

If you look at ifi_default.h you will see the following defines:

#define FALSE 0
#define TRUE !FALSE

It might make more sense if the way you coded it was simply in your logic to increment timer

if(!disabled_mode) // disabled_mode == FALSE
timer += 1;
