Hey all,
I probably would've asked this earlier, but I just followed the diagrams and instructions blindly last year.
I've searched and can't find any relevant threads, so here's my question.
After reading over the CMUcam documentation, I see that the camera board has a TTL port. I remembered this from the RC, so I read the docs for it, and sure enough, we have a TTL port there. So, I have to know, why do we use a TTL to RS-232 converter? Is it a matter of convenience (3 wires to run instead of four)? I'll keep using the converter, but I just found this curious.
Weird things happen when you read the manual...
you might actually think!

EDIT: Also, why are auto white balance and auto gain on by default? They must mess with RGB thresholds. Does FIRST measure the color thresholds with the auto settings on? If so, how can I be sure they are reliable? I had a vapor light above our test field bleach the light white. How can I be so sure this won't happen at a competition?
