After working with many experienced software engineers over the years I can confirm that many experienced software engineers have that same opinion. Yet just the camera.c and tracking.c files have 11 debug statements. One of those is implemented in a state machine and is called 18 times.
For all the high school programmers watching out there, creating robust software systems is an important consideration in software design, even in a resource limited machine. I have programmed on much smaller systems than the IFI. Just because you think certain conditions should not happen does not mean that they never will.

I know. :rolleyes: I will persue it until I can track down the error we observed. |
